Accelerating feature delivery in software development

My company develops security products for all major operating systems. We work with startups and with big companies, all striving to develop features (functional and non-functional) as fast and as good as possible.

While on the first view this seems like a contradiction, there are actually ways of implementing exactly this.

For security software development teams aiming to deliver features more frequently, streamlined processes and efficient workflows are essential.

You guessed, the keywords are agile methods with the related activities such as automated testing, strategic prioritization, agile delivery, efficient workflows, regular and early feedback.

Below are several approaches that emphasize frequent and reliable delivery.

Define requirements with speed in mind

Clear, concise requirements set a strong foundation for quick delivery. Ensuring each feature has straightforward objectives and well-defined acceptance criteria reduces delays caused by back-and-forth clarifications. For security-focused teams, requirements should include key security considerations without overloading the development process. By clarifying expectations from the start, developers can stay on track, avoiding unnecessary revisions and accelerating overall delivery. This being said, also do not change the direction too often (called Pivoting). If you don’t allow feature to “sit”, the product will never reach maturity.

Setup incremental, agile delivery

Breaking down feature development into small, manageable increments supports faster delivery. Rather than waiting for a full release, an incremental approach allows developers to deliver small updates frequently. This Agile-inspired method brings quick wins, shortens feedback cycles, and lets teams adjust direction as needed based on real-world usage. Incremental delivery ensures that new functionality reaches users sooner, making the product more responsive to changing needs.

Optimize for efficiency

Security doesn’t have to slow down delivery. By embedding secure coding practices into the team’s daily workflows, developers can build security right into each feature rather than adding it at the end. Code reviews focused on security can be streamlined with checklists or automated tools, keeping the process efficient. This “security-first” mindset ensures that features remain secure while minimizing delays, as there’s no need for last-minute security fixes.

Invest in CI/CD

Automated testing is key to quick, reliable feature deployment. Automated tests that cover basic functionality and security requirements provide instant feedback, allowing developers to identify and address issues faster. Implementing continuous integration (CI) tools that automatically trigger these tests during development helps the team validate new features on the go. By automating tests, the team gains more time for development and can release updates with minimal manual intervention.

Integrating DevSecOps practices into the development pipeline enables seamless security without slowing down delivery. Automated security checks within the CI/CD pipeline provide fast, reliable security validations, allowing developers to address issues before deployment. This approach keeps the pipeline moving smoothly, as security checks become an integrated part of the process, rather than an additional step that slows down delivery.

Encourage collaborative and efficient workflow

Encourage open communication between developers, security teams, and testers to streamline workflows. Collaborative sessions for discussing roadblocks or coordinating on shared goals help prevent bottlenecks. An open environment where team members share updates and resolve issues collectively accelerates progress by addressing concerns in real time. By emphasizing collaboration, teams can work faster, catching potential blockers early and adapting quickly to new requirements.

Use regular retrospectives to identify and remove delivery obstacles

Post-release retrospectives focused on delivery efficiency help identify and eliminate roadblocks. By analyzing each release or sprint for delays and other issues, teams can identify specific pain points in the development or deployment process. These retrospective sessions allow the team to adjust practices and improve their ability to deliver quickly, refining the workflow with each iteration.

How-To create Security User Stories

In the previous article, we explored how Scrum enables teams to add security to the backlog and prioritize it based on risk.

Incorporating security into the SDLC ensures that security is not an afterthought but an integral part of the development process.

Security User Stories are specific, actionable items that articulate the security needs of the software in the same way functional requirements are handled.

Writing Security User Stories complements this process by providing clear, actionable security requirements that can be integrated into each sprint.

By treating security stories with the same importance as functional stories, developers can ensure that the software they build is not only feature-complete but also secure.

 

What are Security User Stories?

Security User Stories are descriptions of security requirements written from the perspective of the user or the system. They focus on specific security needs, ensuring that the software not only meets functional requirements but also protects against potential vulnerabilities. Just like traditional user stories that describe a feature or function, security stories express how the system should behave securely.

A typical Security User Story follows the same format as a regular user story:

  • As a [role], I want [goal], so that [benefit].

For example, a Security User Story for web development might look like this:

  • “As a user, I want my session to expire after 15 minutes of inactivity, so that my account is protected from unauthorized access.”

Why are Security User Stories Needed?

Security is often treated as an afterthought, addressed late in the development process or after an incident occurs. This reactive approach leads to vulnerabilities, increased technical debt, and costly security fixes post-release. Security User Stories shift this paradigm by making security an integral part of the development process from the outset. They are necessary for several reasons:

  1. Proactive Security Integration: By incorporating security needs into the backlog from the start, you ensure that security considerations are addressed in each sprint, reducing the risk of vulnerabilities later on.
  2. Clear Requirements for Developers: Security User Stories provide clear, actionable security requirements, helping developers understand exactly what is expected to make the software secure.
  3. Accountability: Writing security stories holds the development team accountable for implementing security features and allows for better tracking of security tasks within the development cycle.
  4. Risk Mitigation: When security is considered early in the SDLC, potential security issues are identified and addressed before they become significant risks. This aligns with the concept of “Shift Left” security, where security is integrated into earlier stages of the development process.

How to Use Security User Stories

Security User Stories should be written as part of the Product Backlog and prioritized based on the level of risk or impact. Here’s how to use them effectively:

  1. Collaboration with Security Experts: Work with security professionals to identify potential threats and risks specific to the application or platform. They can help create and refine security user stories based on threat modeling and vulnerability assessments.
  2. Define Acceptance Criteria: Each Security User Story should have clear, testable acceptance criteria. These criteria define when the story is considered complete and what tests should be performed to verify the security requirement has been met.
  3. Prioritize Based on Risk: Security User Stories should be prioritized just like functional features, based on their importance. Stories that address high-risk vulnerabilities, such as authentication or encryption, should be prioritized early in the development cycle.
  4. Regular Review and Updates: Security is an evolving field. As new threats emerge, Security User Stories should be reviewed and updated to address the latest vulnerabilities. Regular threat assessments help ensure the backlog remains current.

Examples of Security User Stories Across Different Platforms

1. Web Application Development

Web applications face numerous security threats, from SQL injection to Cross-Site Scripting (XSS). Below are examples of Security User Stories that address common web application security issues:

  • “As a user, I want my password to be stored securely using a strong hashing algorithm like bcrypt, so that my account is protected from unauthorized access.”
  • “As a system, I want to validate all user inputs server-side to prevent injection attacks.”
  • “As a system, I must use HTTPS for all data transmitted between the client and the server, to ensure data confidentiality.”
  • “As a user, I want to be logged out after 15 minutes of inactivity, so that my session cannot be hijacked.”

2. Windows Software Development

Windows software may face risks such as privilege escalation or malicious code execution. Security User Stories for Windows development could include:

  • “As a user, I want my application to run with the minimum necessary privileges, so that the system is protected from privilege escalation attacks.”
  • “As a system administrator, I want all logs to be stored securely and be tamper-proof, so that I can audit user activities reliably.”
  • “As a developer, I want the application to verify all digital signatures before executing code, to ensure the code has not been tampered with.”
  • “As a system, I want to enforce Data Execution Prevention (DEP) to prevent malicious code from executing in the memory.”

3. Android App Development

Mobile applications, particularly Android apps, face unique security challenges, such as improper storage of sensitive information and unauthorized access to device features. Examples of Android-related Security User Stories include:

  • “As a user, I want my sensitive data (e.g., passwords, payment information) to be encrypted using the Android Keystore system, so that my data is safe even if the device is compromised.”
  • “As a developer, I want the app to request only the necessary permissions, so that the user’s privacy is respected.”
  • “As a user, I want to be required to authenticate using biometrics before making sensitive changes, such as resetting my password, to ensure the security of my account.”
  • “As a system, I want to securely store session tokens and prevent them from being accessible via insecure storage mechanisms (e.g., SharedPreferences).”

4. iOS App Development

iOS apps must adhere to strict privacy and security guidelines, and improper handling of user data can lead to severe breaches. Below are Security User Stories specific to iOS development:

  • “As a user, I want all sensitive information (e.g., authentication tokens) to be stored in the iOS Keychain, so that my data is protected from unauthorized access.”
  • “As a system, I want to ensure that network communication is secured using TLS 1.2 or above, to protect against man-in-the-middle attacks.”
  • “As a user, I want to enable Face ID for sensitive transactions (e.g., payments), to ensure that unauthorized users cannot perform critical actions.”
  • “As a developer, I want to implement App Transport Security (ATS) to ensure all connections are encrypted.”

Conclusion

Security User Stories are a powerful tool for developers to integrate security into their development process. By writing clear, actionable stories with defined acceptance criteria, development teams can proactively address security risks while ensuring that they meet functional requirements.

Whether you’re building a web app, Windows software, or mobile applications for Android or iOS, incorporating Security User Stories into the backlog ensures that security remains a priority throughout the SDLC.

With this approach, developers can create secure, reliable software that meets the needs of both the business and the users.

Understanding Defense in Depth in IT Security

The recent outage caused by Crowdstrike’s faulty update has create a lot of discussions. I wrote a post on LinkedIn where I asked the readers why are IT professionals using Crowdstrike on some systems that shouldn’t be in need of such protection in the first place.

The answers in various groups were mostly related to:

  • protect everything against everyone
  • assume the worse
  • assume that you are compromised.

I do not agree with such a shallow answer. And this raises a question about Defense in Depth.

Defense in Depth

Defense in Depth is a cybersecurity strategy that employs multiple layers of security controls to protect an organization’s assets and information. This approach is based on the premise that no single security measure is foolproof. By implementing several layers of defense, even if one control fails, others are in place to mitigate risks. The concept is inspired by military defense strategies, where a series of defensive positions are used to delay or prevent an attack.

A common misconception about Defense in Depth is that it requires identical security measures across all layers of an IT environment. In reality, this is neither necessary nor practical. Different layers have different requirements based on their specific functions, vulnerabilities, and the types of threats they are exposed to. Applying the same controls universally can lead to inefficiencies, increased costs, and potential performance issues.

In my opinion, this is what happened in many cases during the Crowdstrike outage: admins installed the EDR solution simply on all available devices, without doing an analysis of the threats they are exposed to. This is called threat modeling, and the first step after identifying the assets to protect is to analyze their threat landscape: this is the set of threats they are potentially exposed to. Once the potential threats are identified, then the appropriate security controls can be defined. But, it is important that the right controls are used based on the risk level of the potential threat. The mistake here is that people try to protect against any potential risk, no matter how improbable it might be. So, it is not worth to protect against every potential risk.

But, this operation is, at least at first sight, expensive, time consuming and very few people know how to do it.

So, what happens in most cases is that people consider to be cheaper to buy additional licenses and accept easily a slight reduction in performance due to the tool monitoring everything (“throw” more hardware on it).

And this might be OK, if everything works perfect all the time. Well, it doesn’t !

If this sounds too theoretical, then let’s have a closer look at various layers where applications run.

  • Running at the Web Application Layer: This layer might need strong authentication mechanisms, input validation, and encryption to protect against web-based attacks such as SQL injection or cross-site scripting (XSS).
  • Running at the Network Layer: Here, firewalls, intrusion detection systems (IDS), and virtual private networks (VPNs) are more appropriate to guard against network-based threats like DDoS attacks or unauthorized access.
  • Running at the Endpoint Layer: Devices such as laptops and mobile phones might require antivirus software, device encryption, and endpoint detection and response (EDR) solutions to prevent malware infections and data breaches.

Each layer of security addresses different risks, and the controls should be tailored to the specific threats and the environment.

For instance, a high-value database containing sensitive customer information might warrant multiple layers of encryption, strict access controls, and regular auditing. In contrast, a low-value, non-critical application might only require basic security measures.

Of course, there are applications having parts that run on more than one layer. When this happens, then you must correctly create the threat model and identify the risks at each layer.

For example, if you have a computer which just displays flights schedules, without having an interaction with the exterior other than retrieving data from an internal webservice, you probably do not need a dedicated endpoint security product for it.

Why? Because you will not allow access to the machine other than the service account for patches and running the required software.

If you’re unsure, and the machine runs Windows, than the default Defender is more than enough.

Create a Threat Model for your endpoints

If you don’t know how to create a threat model for an endpoint (and not only Windows, MacOS and Linux are equally affected), here is a list of potential threats and their mitigations.

Important note:
If you apply correctly the principles of Defense in Depth, you will NEVER all all these potential risks applicable to your devices.

Even if you remotely consider that some or all these risks can occur, do not forget that the Risk is proportional to the Probability of occurrence and Impact effect:

  • Probability of occurrence – what are the chances that the risk actually occurs: Very probably, Probably, Sometimes, Unlikely, Never.
  • Impact effect: Catastrophic, Very high, High, Medium, Low.

Potential Risks on an Endpoint

  • Malware Infections

    • Risk: Viruses, Trojans, ransomware, spyware, and other malicious software can compromise the system.
    • Security Controls:
      • Antivirus/anti-malware software
      • Regular system scans and updates
      • Application whitelisting
      • Sandboxing suspicious files
      • Backup with versioning control (good for ransomware attacks)
  • Unpatched Software

    • Risk: Vulnerabilities in outdated software can be exploited by attackers.
    • Security Controls:
      • Automated patch management systems with rollback functionality
      • Regular software updates
      • Vulnerability scanning tools
      • Centralized patch distribution
  • Unauthorized Access

    • Risk: Unauthorized users may gain access to the endpoint, leading to data breaches or system compromise.
    • Security Controls:
      • Strong password policies
      • Multi-factor authentication (MFA)
      • User account control (UAC)
      • Role-based access controls (RBAC)
  • Data Theft

    • Risk: Sensitive data may be copied, transmitted, or stolen from the endpoint.
    • Security Controls:
      • Full disk encryption (e.g., BitLocker)
      • Data loss prevention (DLP) tools
      • USB port control and removable media encryption
      • Secure backup solutions
  • Physical Theft

    • Risk: The endpoint itself may be physically stolen, leading to loss of data and access to the network.
    • Security Controls:
      • Physical security measures (locks, secure storage)
      • Device tracking and remote wipe capabilities
      • Full disk encryption
      • BIOS/UEFI passwords
  • Drive-by Downloads

    • Risk: Malicious websites may automatically download and install malware without user consent.
    • Security Controls:
      • Web filtering and browser security plugins
      • Regular updates to browsers and plugins
      • Application whitelisting
      • Disabling automatic execution of scripts in browsers
  • Network-based Attacks

    • Risk: Attackers may exploit vulnerabilities in the network to compromise the endpoint.
    • Security Controls:
      • Personal firewall
      • Network segmentation
      • Secure VPN connections
      • Intrusion detection and prevention systems (IDPS)
  • Misconfigured Security Settings

    • Risk: Insecure configurations can leave the endpoint vulnerable to attacks.
    • Security Controls:
      • Regular security audits and compliance checks
      • Hardening guides and best practices (e.g., CIS benchmarks)
      • Group policies for centralized management
      • Security baselines and templates

Potential Human Risks

Phishing Attacks

  • Risk: Users may be tricked into divulging sensitive information or downloading malicious software through deceptive emails or websites.
  • Security Controls:
    • Email filtering with anti-phishing capabilities
    • User awareness training
    • Web filtering and reputation services
    • Multi-factor authentication (MFA)

Insider Threats

  • Risk: Malicious or negligent insiders may intentionally or unintentionally cause harm.
  • Security Controls:
    • User activity monitoring and logging
    • Least privilege principle
    • Endpoint detection and response (EDR)
    • Insider threat detection tools

Instead of conclusion: Balancing Security and Usability

The most critical aspect of Defense in Depth is balancing security and usability.

Over-securing can lead to decreased productivity, increased costs, and user dissatisfaction.

For instance, implementing multi-factor authentication (MFA) at every step might significantly slow down legitimate users, leading to frustration and potential workarounds that can undermine security.

A well-designed Defense in Depth strategy finds the right balance by applying strict controls where necessary and lighter measures where the risk is lower.

The goal is to create a robust security posture that protects against a wide range of threats without overburdening the system or its users.

ISO 27001:2022 and TISAX: overlaps and differences

Introduction

ISO 27001:2022 and TISAX VDA ISA 6.0 are two prominent standards in the realm of information security management, particularly within the automotive industry. While ISO 27001 provides a global framework for establishing, implementing, maintaining, and continually improving an information security management system (ISMS), TISAX (Trusted Information Security Assessment Exchange), based on the VDA ISA (Information Security Assessment) framework, is tailored to meet the specific needs of the automotive sector.

This article delves into the nuances of these two standards, highlighting their overlaps, the ways in which TISAX leverages ISO 27001, and the distinct features that set TISAX apart.

Overview of ISO 27001:2022

ISO 27001:2022 is the latest revision of the internationally recognized standard for information security management. It provides a comprehensive approach to managing sensitive company information so that it remains secure. This involves a risk management process, which includes people, processes, and IT systems by applying a risk management process.

Key Features of ISO 27001:2022

  • Risk-Based Approach: Emphasizes the identification and management of risks through a continuous improvement process.
  • Annex A Controls: Contains 93 controls categorized under four themes: Organizational, People, Physical, and Technological.
  • PDCA Cycle: The Plan-Do-Check-Act cycle is integral for continuous improvement.
  • Context of the Organization: Requires understanding of internal and external factors impacting information security.
  • Leadership Commitment: Highlights the importance of top management’s involvement in the ISMS.

Overview of TISAX VDA ISA 6.0

TISAX, a standard specific to the automotive industry, is based on the VDA ISA (Verband der Automobilindustrie Information Security Assessment) catalog. TISAX ensures that automotive manufacturers and suppliers meet strict information security requirements to protect sensitive information.

Key Features of TISAX VDA ISA 6.0

  • Sector-Specific: Tailored specifically for the automotive industry.
  • VDA ISA Catalog: Based on the VDA ISA framework, which is a detailed checklist of requirements and controls. It is split in several areas of interest:
    • Information security – containing everything that belongs to an ISMS
      • IS Policies and Organization
      • Information Security Policies
      • Organization of Information Security
      • Asset Management
      • IS Risk Management
      • Assessments
      • Incident and Crisis Management
      • Human Resources
      • Physical Security
      • Identity and Access Management
      • Identity Management
      • Access Management
      • IT Security / Cyber Security
      • Cryptography
      • Operations Security
      • System acquisitions, requirement management and development
      • Supplier Relationships
      • Compliance
    • Prototype Protection – focused on physical and cyber protection of prototypes
    • Data Protection – focused on policies for protecting privacy and secrets
  • Assessment Levels: Comprises different levels of assessment depending on the type of information and its criticality.
  • Labeling System: Provides a TISAX label indicating compliance, which can be shared with partners within the automotive ecosystem.
  • Focus on KPIs: VDA ISA provides a large set of examples on how to measure certain controls effectively.

Overlaps between ISO 27001:2022 and TISAX VDA ISA 6.0

While TISAX and ISO 27001 serve different purposes, they share several common elements. TISAX leverages the fundamental principles of ISO 27001, creating a robust framework that is both comprehensive and specific to the automotive sector.

In the VDA ISA 6.x (and previous) there are the columns “Reference to other standards” (column P) and “Reference to implementation guidance” (column Q) which point to known standards. Of course, there is no coincidence that the most reference standard is the ISO 27001 in both versions 2022 and 2013.

In the guidance we usually see reference to the Annex A of the ISO 27001 standard (both versions).

 

In the column W there is “Further information” containing explanations of what can be described by the respective control.

Risk Management

Both ISO 27001 and TISAX emphasize a risk-based approach to information security. ISO 27001 mandates a formal risk assessment process, while TISAX incorporates this through the VDA ISA requirements, ensuring that organizations identify and manage risks relevant to the automotive industry.

Control Objectives and Controls

ISO 27001:2022 and TISAX VDA ISA 6.0 share a common structure in terms of control objectives and specific controls. Many of the controls listed in Annex A of ISO 27001 are reflected in the VDA ISA catalog, ensuring a comprehensive approach to securing information.

While this is a common trait shared by the standards, the TISAX is making use of other standards than ISO 27001: NIST, BSI other ISO standards.

Continuous Improvement

Both standards advocate for continuous improvement. ISO 27001’s PDCA cycle and TISAX’s periodic reassessment and updating of security measures ensure that organizations continually enhance their security posture in response to evolving threats.

TISAX VDA ISA has a sheet called “Maturity Levels” containing descriptions of the Maturity Levels 0 to 5.

Documentation and Record-Keeping

ISO 27001 requires detailed documentation of the ISMS, including risk assessments, policies, and procedures. TISAX also mandates thorough documentation as part of its assessment criteria, ensuring that organizations maintain a clear record of their security practices.

Third-Party Management/Suppliers Relationships

Third-party risk management is a critical component in both standards. ISO 27001 includes controls for managing supplier relationships and ensuring their compliance with information security requirements. Similarly, TISAX places a strong emphasis on securing information exchanged with suppliers and partners, crucial for maintaining the integrity of the automotive supply chain.

Differences between ISO 27001:2022 and TISAX VDA ISA 6.0

Despite their overlaps, ISO 27001 and TISAX have several distinctions, reflecting their different scopes and target audiences.

Industry Focus

ISO 27001 is a generic standard applicable to any organization, regardless of its sector. TISAX, however, is designed specifically for the automotive industry, addressing unique challenges such as the secure exchange of data between manufacturers and suppliers.

Assessment Process

ISO 27001 involves a formal certification process conducted by accredited bodies, leading to ISO 27001 certification. TISAX, on the other hand, employs a mutual assessment model where organizations are assessed by ENX approved audit providers, and successful assessments result in a TISAX label. This label can then be shared with other automotive industry stakeholders, facilitating trust and compliance.

Control Specificity

While ISO 27001 provides a broad framework of controls applicable to various industries, TISAX’s controls are highly specific to the automotive sector. The VDA ISA catalog includes detailed requirements for protecting manufacturing data, ensuring compliance with industry-specific regulations, and safeguarding automotive intellectual property.

Levels of Assessment

TISAX introduces different levels of assessment (Basic(Must and Should), High, and Very High) depending on the sensitivity and criticality of the information being protected. ISO 27001 does not have a tiered assessment system but rather a uniform certification standard.

Focus Areas

TISAX places significant emphasis on physical security, secure development of automotive products, and compliance with industry-specific legal requirements. ISO 27001, while comprehensive, does not delve into sector-specific issues with the same level of detail.

Commercial vs Open standards

ISO 27001 is an open international standard governed by the Internation Standards Organisation (ISO). The TISAX trademark is owned by the organization ENX, formed by many OEMs in automotive sector.

 

Implementation of TISAX Using ISO 27001

TISAX leverages ISO 27001’s framework to build a robust and industry-specific information security system. Many organizations begin with ISO 27001 certification and then adapt their ISMS to meet the additional requirements of TISAX.

Integration of Standards

  1. Foundation in ISO 27001: Organizations often establish a basic ISMS in accordance with ISO 27001. This includes conducting risk assessments, implementing controls, and ensuring continuous improvement.
  2. Customization to TISAX Requirements: Once the foundational ISMS is in place, organizations tailor it to meet TISAX requirements, which may involve additional controls specific to automotive data security and third-party management.
  3. Assessment and Labeling: Organizations undergo a TISAX assessment conducted by an approved audit provider. Successful completion results in the issuance of a TISAX label, demonstrating compliance with industry-specific security requirements.

Benefits of Integration

Integrating ISO 27001 with TISAX offers several benefits:

  • Streamlined Compliance: Simplifies the process of meeting both generic and sector-specific security requirements.
  • Enhanced Trust: The TISAX label, backed by ISO 27001’s rigorous framework, enhances trust among automotive industry partners.
  • Cost Efficiency: Leveraging ISO 27001 as a foundation reduces duplication of effort and resources in implementing security measures.

Conclusion

ISO 27001:2022 and TISAX VDA ISA 6.0 represent critical standards for information security, particularly within the automotive sector. While they share common principles such as risk management and continuous improvement, TISAX’s industry-specific focus and detailed requirements for automotive set it apart. By leveraging the robust framework of ISO 27001, organizations can start to effectively implement TISAX, ensuring comprehensive protection of sensitive automotive data and fostering trust within the industry.

Understanding the connections between these standards and their unique requirements is very important for organizations aiming to achieve a high level of information security and compliance.

NIS-2: 10 common misconceptions about the regulation

We wrote here about NIS2 and we will continue to add more content about it.

Because we are getting closer to October 17th, many people are getting more and more nervous about NIS2.

Despite its significance, there are numerous misconceptions and misinterpretations circulating about the scope and implications of this regulation.

This article aims to clarify some of the misconceptions,  which I collected mostly from LinkedIn and articles about NIS-2.

 

Note:

“NIS2” and “NIS-2” are exactly the same thing. I am using both in this article only because of SEO.

 

 

1. NIS2 starts being applied in the EU starting 17.10.2024

Truth is that the regulation is already applicable in the EU since it was approved. This deadline applies to the individual countries of the EU to convert and apply the NIS2 requirements in local laws.

If national authorities fail to properly implement EU laws, the Commission may launch a formal infringement procedure against the country in question. If the issue is still not settled, the Commission may eventually refer the case to the Court of Justice of the European Union.

 

2. Limited scope of application

Contrary to the belief that NIS-2 only applies to large tech companies, the directive significantly broadens its scope compared to its predecessor, NIS.

NIS-2 extends beyond just critical infrastructure sectors like energy and transport, encompassing a wide array of sectors such as digital services, public administration, and healthcare.

It mandates a security and incident reporting framework that applies to both Essential and Important Entities, significantly expanding the list of sectors and services affected.

3. NIS-2 Is Just About Cybersecurity

While cybersecurity is a core component, NIS-2 is not merely about preventing cyberattacks. The directive emphasizes a comprehensive approach to security, which includes resilience against a wide range of threats.

This includes but it is not limited to:

  • supply chain security,
  • incident response, and
  • crisis management.

It establishes a baseline for security measures and incident notifications that entities must adhere to, ensuring a uniform level of security across member states.

4. NIS-2 compliance is the same across all EU countries

Although NIS-2 sets a framework for cybersecurity across the EU, member states have some flexibility in implementation. This means that there can be variations in how directives are enforced from one country to another, depending on local laws and regulations.

Companies operating across multiple jurisdictions need to be aware of and comply with local variations to ensure full compliance.

5. Heavy penalties are the main compliance driver

While it is true that NIS-2 can impose hefty fines for non-compliance, focusing solely on penalties misses the broader objective of the directive.

NIS-2 is designed to cultivate a culture of security and resilience. It encourages entities to proactively manage their cybersecurity risks and to collaborate with national authorities.

This cooperative approach is fundamental to enhancing the overall cybersecurity posture of the EU.

6. NIS-2 does not affect third-party suppliers

NIS-2 places explicit requirements on the security practices of third-party suppliers. Entities covered under the directive are required to ensure that their supply chains are secure.

This includes mandatory risk assessments and incident reporting requirements that extend to service providers, reflecting an understanding that security is only as strong as the weakest link in the supply chain.

 

7. NIS-2 contains rules for AI, IoT, Industry 4.0.

NIS-2 sets a framework for cybersecurity and it does not address anything in particular. However, the rules described can be very well applied to companies in the fields like those mentioned that fall under the regulation applicability.

The companies active in Digital Infrastructure Services (Internet Nodes, DNS Service Providers, TLD Registries, Cloud Providers, Data Centers, Content Delivery Networks, Trust Services, Communication Networks, Communication Services ) and in

ICT Service Management (B2B only) (Managed Services (IT, Networks/Infrastructure, Applications), Managed Security Services (Risk and Cyber Security) ) are potentially directly affected by the regulation. However, there are clear criteria about which companies are affected.

 

8. Any company with activity in the domains marked as Important and Essential is affected by NIS-2

Although the domains are under the NIS-2 regulation, a company is affected if it meets the criteria:

  • Essential Entities (EE):
    • at least 250 employees and
    • 50 Mil € revenue
  • Important Entities (IE):
    • at least 50 employees and

If a company doesn’t have these characteristics, then, in general, it is not affected by the regulation directly. It is highly recommended that even in such cases the companies follow the regulation’s requirements, since it will increase their resilience against cyber attacks.

However, an entity may still be considered “essential” or “important” even if it does not meet the size criteria, in specific cases such as when it is the sole provider of a critical service for societal or economic activity in a Member State.

 

9. All affected companies must certify for NIS-2

A the time of writing this post there is no certification for NIS-2. This might change in the future, especially when because we don’t know at this time how the regulation will be implemented in each of the EU member states.

There are consulting companies that sell consulting services and guarantee that a company will get the “NIS-2  certification” if they bus their services. While buying consulting is in general a good thing, the only thing that can be obtained is help in meeting the requirements of the regulation.

I recommend to stay away from offers that promise things that don’t exist.

 

10. Companies can buy software/hardware products to become conform with NIS-2

Although conformity is sometimes made easier by using specialized software and hardware products, there is no requirement or recommendation to purchase anything.

Some security providers and consulting companies are offering On The Shelf  (OTS) products that promise immediate conformity with NIS-2 (or guarantee obtaining a “certification” – see point 9 above).

If you look at the series of articles in the NIS2 area of this website, you will see that actually quite a lot of  steps involve an ISMS, a cybersecurity framework, cybersecurity products and so on.

These can be implemented with commercial or open source products, but there is still need to know where and how to install them in order to become conform.

I can very well imagine that there will be soon commercial offerings with sets of templates for implementing the NIS-2 requirements, just like there are with ISO 27001, TISAX and other certifications.

Understanding ISO 27001:2022 Annex A.8 – Asset Management

 

ISO 27001:2022 Annex A.8, “Asset Management,” addresses the importance of identifying, classifying, and managing information assets within an organization. This annex emphasizes the need for organizations to establish processes for inventorying assets, assessing their value, and implementing appropriate controls to protect them. In this technical educational article, we’ll explore how to implement Annex A.8 in practice, highlight its significance, and discuss the audit process for assessing compliance.

 

 

 

 

What is an Asset ?

In the context of ISO 27001:2022, an asset refers to anything that has value to an organization and needs to be protected.

This includes not only tangible assets such as

  • Physical assets:
    • hardware and equipment
    • buildings
    • vehicles
  • People
    • Employees
    • Customers
    • Suppliers
  • Software
  • Intangible
    • Data
    • Intellectual property
    • Proprietary information
    • Reputation
    • Market Share

ISO 27001:2022 recognizes that assets come in various forms and play a crucial role in achieving an organization’s objectives.

What makes an asset worth to be added to the list?

Here are some key points to consider regarding assets in the context of ISO 27001:2022:

  1. Identification: Organizations need to identify and inventory all their assets, including both tangible and intangible ones. This involves understanding what assets the organization possesses, where they are located, and who has ownership or responsibility for them. If this can be done, then the asset is worth enough to be considered to be managed.
  2. Classification: Assets should be classified based on their value, sensitivity, and criticality to the organization. This classification helps prioritize protection efforts and allocate resources effectively. For example, sensitive customer data may be classified as high-value assets requiring stringent security measures. If an asset is classified with a category that makes it important for the company, then it should be definitely managed.
  3. Risk Management: Assets are subject to various risks, including cybersecurity threats, natural disasters, and human error. Organizations need to conduct risk assessments to identify and mitigate threats to their assets effectively. This involves evaluating the likelihood and potential impact of risks and implementing controls to reduce risk to an acceptable level.
  4. Protection: Based on the risk assessment for an asset, organizations must implement appropriate controls to protect their assets from unauthorized access, disclosure, alteration, or destruction. This includes measures such as access controls, encryption, backup procedures, and physical security measures. Based on the measures identified, an asset can be quite expensive to be protected, but losing it or damaging it might prove to be even more expensive.

 

Importance of Asset Management

Effective asset management is crucial for organizations to safeguard their information assets, optimize resource allocation, and mitigate risks. Annex A.8 underscores this importance by:

  1. Risk Reduction: Identifying and classifying information assets helps organizations prioritize security measures and allocate resources effectively to mitigate risks.
  2. Compliance: Maintaining an accurate inventory of assets and implementing appropriate controls ensures compliance with regulatory requirements and industry standards.
  3. Cost Savings: Efficient asset management practices enable organizations to optimize resource utilization and avoid unnecessary expenses associated with redundant or underutilized assets.

Implementing Annex A.8 in Practice

To effectively implement Annex A.8, organizations can follow these practical steps:

  1. Asset Identification: Begin by identifying all information assets within the organization, including hardware, software, data, and intellectual property. Establish criteria for identifying assets, such as ownership, criticality, and sensitivity.Example: Develop an asset inventory list categorizing assets based on their type, location, owner, and importance to business operations.
  2. Asset Classification: Classify information assets based on their value, sensitivity, and criticality to the organization. Define classification levels or categories to differentiate between assets requiring different levels of protection.Example: Classify data assets as public, internal use only, confidential, or restricted based on their sensitivity and impact on the organization if compromised.
  3. Asset Ownership: Assign ownership responsibilities for each information asset to designated individuals or departments within the organization. Clearly define roles and responsibilities for managing and protecting assigned assets.Example: Assign data ownership responsibilities to business units or functional departments responsible for creating, accessing, or managing specific types of data.
  4. Risk Assessment: Conduct risk assessments to identify threats, vulnerabilities, and potential impacts on information assets. Assess the likelihood and impact of potential risks to prioritize mitigation efforts.Example: Perform a vulnerability assessment to identify weaknesses in IT systems and applications that could expose information assets to security threats.
  5. Control Implementation: Implement appropriate controls to protect information assets from unauthorized access, disclosure, alteration, or destruction. Select controls based on the results of risk assessments and compliance requirements.Example: Implement access control mechanisms, such as user authentication, role-based access control (RBAC), and encryption, to safeguard sensitive information assets from unauthorized access.

Audit of Compliance with Annex A.8

Auditing compliance with Annex A.8 is essential for evaluating an organization’s adherence to asset management requirements. Here’s how the audit process typically unfolds:

  1. Audit Preparation: The organization gathers documentation related to asset management policies, procedures, and controls. An audit team is appointed to facilitate the audit process.
  2. Audit Planning: The audit team defines the audit scope, objectives, and criteria. They develop an audit plan outlining the audit activities, timelines, and responsibilities of auditors and auditees.
  3. On-site Audit: Auditors conduct on-site visits to assess the implementation of asset management controls. They review documentation, interview personnel, and observe asset management practices in action. Auditors may use checklists or standardized assessment tools to evaluate compliance.
  4. Audit Findings: After the on-site audit, auditors analyze their findings and identify areas of non-compliance or improvement opportunities. They document their observations, including strengths and weaknesses in the organization’s approach to asset management.
  5. Reporting: Auditors prepare an audit report summarizing their findings, conclusions, and recommendations for corrective actions. The report is shared with senior management and relevant stakeholders for review and action.
