Understanding ISO 27001:2022 Annex A.9 – Access Control

/in

We started the ISO 27001:2022 series with the promise of explaining how the 14 categories of controls can be implemented.

Today we address ISO 27001:2022 Annex A.9, “Access Control”.

Access control is a fundamental component of information security management systems (ISMS).

It provides guidelines for implementing controls to ensure that only authorized individuals have access to information assets and resources.

 

 

Importance of Access Control

Access control is crucial for protecting sensitive information, preventing unauthorized access, and maintaining the confidentiality, integrity, and availability of organizational assets. Annex A.9 underscores this importance by:

  1. Protecting Information Assets: Implementing access controls helps safeguard sensitive data, intellectual property, and critical systems from unauthorized disclosure, modification, or destruction.
  2. Enforcing Least Privilege: Access control mechanisms ensure that individuals have access only to the resources and information necessary to perform their job responsibilities, minimizing the risk of misuse or abuse.
  3. Mitigating Insider Threats: Controls such as user authentication, authorization, and auditing help detect and deter insider threats, including malicious activities by employees, contractors, or third-party users.

Implementing Annex A.9 in Practice

To effectively implement Annex A.9, organizations can follow these practical steps:

  1. Access Control Policy: Develop an access control policy that defines the principles, rules, and procedures governing access to information assets and resources. The policy should outline requirements for user authentication, authorization, access provisioning, and access revocation.Example: Define a password policy specifying requirements for password complexity, expiration, and reuse to strengthen authentication controls.
  2. User Authentication: Implement robust authentication mechanisms to verify the identity of users accessing organizational systems and resources. This may include passwords, biometric authentication, multi-factor authentication (MFA), or single sign-on (SSO) solutions.Example: Deploy MFA solutions requiring users to authenticate using a combination of passwords and one-time passcodes sent to their mobile devices for accessing sensitive systems.
  3. Authorization Controls: Define access control lists (ACLs), roles, and permissions to determine the level of access granted to users based on their roles, responsibilities, and organizational hierarchy.Example: Assign roles such as “administrator,” “manager,” and “user” with corresponding access rights and permissions to resources based on job responsibilities.
  4. Access Provisioning and Revocation: Establish procedures for provisioning access to new users and revoking access for departing employees, contractors, or third-party users in a timely manner.Example: Develop an access request and approval process where users submit access requests, which are reviewed and approved by authorized personnel before access is provisioned.
  5. Monitoring and Auditing: Implement logging and auditing mechanisms to track user activities, monitor access attempts, and detect unauthorized access or suspicious behavior.Example: Configure audit logs to record user login attempts, access permissions changes, and unauthorized access attempts for review and analysis.

Audit of Compliance with Annex A.9

Auditing compliance with Annex A.9 is essential for evaluating an organization’s adherence to access control requirements. Here’s how the audit process typically unfolds:

  1. Audit Preparation: Gather documentation related to access control policies, procedures, and controls. Appoint an audit team to facilitate the audit process.
  2. Audit Planning: Define the audit scope, objectives, and criteria. Develop an audit plan outlining activities, timelines, and responsibilities of auditors and auditees.
  3. On-site Audit: Conduct on-site visits to assess implementation of access control controls. Review documentation, interview personnel, and observe access control practices. Use checklists or assessment tools to evaluate compliance.
  4. Audit Findings: Analyze findings and identify areas of non-compliance or improvement opportunities. Document observations, including strengths and weaknesses in access control implementation.
  5. Reporting: Prepare an audit report summarizing findings, conclusions, and recommendations for corrective actions. Share with senior management and stakeholders for review and action.
  6. Follow-up: Address audit findings by implementing corrective actions and improvements as recommended. Conduct follow-up audits to verify effectiveness of corrective measures and ensure ongoing compliance.

Conclusions

ISO 27001:2022 Annex A.9 emphasizes the importance of access control in protecting information assets and mitigating security risks. By implementing robust access control mechanisms, organizations can prevent unauthorized access, enforce least privilege, and safeguard sensitive information. Regular audits help assess compliance with Annex A.9 requirements and drive continuous improvement in access control practices. Prioritizing access control is essential for organizations seeking to maintain the confidentiality, integrity, and availability of their information assets in an increasingly interconnected and digital world.

Zero Trust in Cybersecurity: from myth to the guide

/in

Every single day I read news on various portals and on LinkedIn and I encounter a lot of buzz words.

Most of the time I just smile recognizing the marketing b**it, and continue to scroll…

This time, I found an article from the Germany’s Federal Bureau of Information Security (BSI) and it was about Zero Trust (DE). Note, this is summary, meant to be full of buzzwords, not a guide or anything similar.

I have to say that Zero Trust used to be a lot more prominent in the Corona years, between 2020 and 2022 than it is now. This shows also the history on IT Security News and Google Trends.

 

What is Zero Trust?

Zero Trust is a cybersecurity framework designed to address the limitations of traditional perimeter-based security models. Oh, if you didn’t read the article on cybersecurity framework, go there and give it a try.

In the past, companies would rely on firewalls and trust the inside network while treating the outside as a potential threat.

Zero Trust, on the other hand, assumes that threats can originate from both inside and outside the network. It promotes a “never trust, always verify” approach or how we usually say, to be politically correct, “trust is good, but control is better”.

 

Core principles

1. Identity Verification

Before granting access every user, device and application attempting to access network resources must go through a verification process.

2. Limited Access Privileges

Users and systems should only have access to the resources, for their tasks; nothing

3. Micro Segmentation

The network is split into separate sections to limit the spread of threats.

4. Continuous Monitoring

Constantly observing and analyzing network activity, user actions and system well being, in time.

5. Flexible Access Control

Access permissions can adjust dynamically depending on the users actions, device security status and contextual factors.

 

Why Zero Trust is such a popular term

Zero Trust is not exclusive to any industry or company size. It can be implemented by any organization looking to enhance its cybersecurity posture. Whether you’re a business or a multinational corporation Zero Trust can be tailored according to your requirements.

Due to the COVID 19 restrictions, all companies had to increase the reliance on cloud services, implement remote work, and proliferate mobile devices, which resulting in an expanded traditional network perimeter.

This transformation has made organizations more vulnerable to cyberattacks.

To summarize, these are the main reasons why Zero Trust has become so popular:

1. Changing Nature of Cyber Threats

With cyber threats becoming advanced and unpredictable organizations need to take measures to defend against them.

2. Impact of Remote Work

The COVID 19 pandemic has accelerated the adoption of work rendering traditional network perimeters ineffective.

3. Embracing Cloud Services

As businesses shift towards cloud computing, data and applications are no longer limited to, on premises environments.

4. Adherence to Data Privacy Regulations

Compliance with data privacy regulations like GDPR and CCPA necessitates the implementation of data protection measures.

Implementing the Zero Trust framework

There is nothing new here, the same steps apply as to any other cybersecurity framework and ISMS.

I will not go into details about it, just go back and read these articles on ISMS and NIS2.

1. Identify and classify your digital assets

2. Implement strong user authentication methods, verify their identities before granting access

3. Ensure that users and systems have the minimum necessary access permissions.

4. Segment your network into smaller zones to limit lateral movement in case of a breach.

5. Deploy real-time monitoring and analysis tools to track anomalies

6. Implement Adaptive Access Control

7. Encrypt data both in transit and at rest

8. Conduct regular security audits

9. Educate employees about the importance of security

10. Develop an Incident Response Plan

How to implement an Information Security Management System (ISMS)

/in

We wrote here https://www.sorinmustaca.com/how-to-nis2-eu-directive/ that the 3rd  step in implementing the requirements of the directive is to establish a cybersecurity framework.

If you haven’t read what a cybersecurity framework means, then you should read article: https://www.sorinmustaca.com/demystifying-cybersecurity-terms-policy-standard-procedure-controls-framework/ .

An ISMS is typically based on the ISO 27001 standard, which provides a framework for establishing, implementing, maintaining, and continually improving information security within an organization.

Establishing a cybersecurity framework is usually achieved together with, or while implementing an Information Security Management System (ISMS) based on a standard like ISO 27001. So, before going to the NIS2 Step 3, I must explain why is it important to have a “good” ISMS.

This article will guide you through the steps to create a solid foundation for the ISMS which uses a cybersecurity framework.

 

Here are the steps you must follow to implement your ISMS:

  1. Get Top Management Support
    • Before you start, synchronize with the top management in order to define company’s goals in this regard. Usually it should be clear, since the company strives to receive a certification like ISO 27001, ISO 16949, TISAX, CSMS, etc..
    • Then secure the commitment and support of senior management by helping them understand the necessary resources and efforts.
    • In all standards that require an ISMS it is imperative to have the commitment of the management because their feedback and support are required in several places along the way.
  2. Scope Definition
    • Define the scope of your ISMS: determine which assets, processes, and locations will be covered by the ISMS.
    • This will help in setting boundaries for your security efforts. Some certifications require an assessment per location and scope, so this needs to be developed properly and in accordance with company’s goals.
  3. Risk Assessment
    • Create policies that help identify and assess information security risks.
    • This involves:
      • How to identifying assets: List all the information assets your organization handles, such as data, hardware, software, and personnel, intellectual property.
      • How to identify threats and vulnerabilities: Determine potential risks and vulnerabilities that could impact your assets.
      • How to assess risks: Analyze the likelihood and potential impact of these risks.
      • How to calculate risk levels: Prioritize risks based on their severity.
  4. Risk Treatment
    • Develop a policy for risk treatment plan:
      • How to implement controls: Select and implement security controls and measures to mitigate identified risks.
      • Document policies and procedures that enforce the creation of security controls.
      • Allocate responsibilities: Assign roles and responsibilities for managing and monitoring security measures.
      • Set risk acceptance criteria: Determine which risks can be accepted, mitigated, or transferred.
  5.  Establish the ISMS Framework
    • Establish the ISMS framework based on ISO 27001:
      • Define information security objectives.
      • Develop an information security policy.
      • Create a risk assessment methodology.
      • Define criteria for risk acceptance.
      • Develop and implement security controls.
  6. Implementation
    • Execute the ISMS based on the established framework:
      • Train employees: Provide information security training to all staff members.
      • Implement security controls: Put in place the technical, administrative, and physical controls identified in your risk treatment plan.
      • Monitor and review: Continuously monitor the effectiveness of your controls and review your risk assessment.
  7. Measurement and Evaluation
    • Regularly measure and evaluate the performance of your ISMS to ensure that it remains effective and aligned with your objectives.
      • Conduct internal audits.
      • Perform security testing (e.g., penetration testing, vulnerability scanning).
      • Analyze security incident data.
  8. Management Review
    • Conduct regular management reviews to assess the ISMS’s performance and effectiveness.
      • Ensure that the ISMS is aligned with the organization’s strategic goals.
      • Make improvements based on review findings.
  9. Continual Improvement
    • Use the results of audits, reviews, and incidents to continually improve the ISMS.
      • Update policies and procedures as needed.
      • Enhance security controls based on new threats and vulnerabilities.
      • Maintain employee awareness and training.
  10. Certification (Optional):
    • If your organization desires ISO 27001 or any other certification, engage an accredited certification body to perform an external audit and certification assessment.
    • Be careful because several certification require a pre-certification or pre-assessment performed either with in-house auditors (internal) or external auditors.
  11. Documentation
    • Maintain detailed documentation of all ISMS activities, including policies, procedures, risk assessments, and audit reports.
    • Maintain a log of all changes in time, because this demonstrates continual improvement and usage.
  12. Training and Awareness
    • Continuously educate and raise awareness among employees regarding information security policies and best practices.
  13. Incident Response and Recovery
    • Develop an incident response plan to address security incidents promptly and effectively.

 

Remember, and make sure that your management remembers as well, that implementing and maintaining an ISMS is an ongoing process. Even if certifications are renewed only after 3 years (usually) it is important that in these 3 years the ISMS is lived.

Regularly update your risk assessments and adapt your security controls to evolving threats and business needs. Continuous improvement is key to the success of your ISMS.

An ISMS, or Information Security Management System, is a systematic approach to managing an organization’s information security processes, policies, and controls. It is a framework that provides a structured and holistic approach to protect the confidentiality, integrity, and availability of sensitive information assets within an organization.

The primary objective of an ISMS is to establish a set of coordinated security practices that align with the organization’s overall business goals and risk management strategies. It involves defining and implementing policies, procedures, guidelines, and controls to manage the security of information assets effectively.

Key components of an ISMS typically include:

  1. Risk Assessment: Identifying and assessing potential risks and vulnerabilities to the organization’s information assets, including data breaches, unauthorized access, and system failures.
  2. Security Policies: Developing comprehensive policies and guidelines that outline the organization’s approach to information security, including acceptable use, data classification, incident response, and access control.
  3. Asset Management: Inventorying and categorizing information assets based on their importance and sensitivity, ensuring proper protection measures are applied accordingly.
  4. Access Control: Implementing controls to manage user access privileges, authentication mechanisms, and authorization processes to ensure that only authorized individuals can access sensitive information.
  5. Incident Response: Establishing procedures and protocols to detect, respond to, and recover from security incidents, including data breaches, malware attacks, or system compromises.
  6. Business Continuity Planning: Developing strategies to maintain critical business operations during and after a security incident or a disruptive event, ensuring minimal impact on the organization’s functions and services.
  7. Security Awareness and Training: Promoting a culture of security within the organization through regular training programs and awareness campaigns to educate employees about security best practices and their roles in protecting information assets.
  8. Continuous Monitoring and Improvement: Regularly monitoring and evaluating the effectiveness of security controls, conducting audits, and implementing improvements to address emerging threats and vulnerabilities.

Commonly recognized standards for implementing an ISMS include ISO/IEC 27001, which provides a globally recognized framework for information security management, and NIST Cybersecurity Framework, developed by the National Institute of Standards and Technology in the United States.

 

ISMS Scope

Key goals of an ISMS are:

1. Protecting Confidentiality and Integrity:

Companies possess a vast amount of confidential information, including customer data, financial records, proprietary processes, and intellectual property. An ISMS provides a structured framework to identify, classify, and protect this valuable information from unauthorized access, disclosure, or modification. By implementing robust security controls and protocols, an ISMS ensures the confidentiality and integrity of sensitive data, reducing the risk of data breaches, leaks, and unauthorized usage.

2. Compliance with Legal and Regulatory Requirements:

In an era of increasing data privacy regulations, companies face stringent legal obligations to protect customer information and comply with industry-specific standards. Implementing an ISMS assists in meeting these requirements by providing a systematic approach to information security management. Whether it’s the General Data Protection Regulation (GDPR), Health Insurance Portability and Accountability Act (HIPAA), or Payment Card Industry Data Security Standard (PCI DSS), an ISMS helps companies establish and maintain a strong security posture, avoiding legal penalties and reputational damage.

3. Mitigating Risks and Vulnerabilities:

Cyber threats and attacks are a constant and evolving concern for businesses of all sizes. An ISMS helps identify potential risks and vulnerabilities within the company’s information systems and infrastructure. By conducting regular risk assessments and implementing appropriate controls, such as firewalls, encryption, and intrusion detection systems, an ISMS minimizes the likelihood of security incidents. It enables proactive monitoring, threat detection, and incident response, ensuring that companies can effectively manage security risks.

4. Enhancing Customer Trust and Competitive Advantage:

In today’s highly competitive marketplace, customers prioritize the security and privacy of their data. By implementing an ISMS, companies demonstrate their commitment to protecting customer information and build trust among their client base. A robust information security framework helps differentiate the organization from its competitors and can be a valuable marketing point, particularly when dealing with sensitive data or operating in industries where security is paramount. Additionally, companies that adhere to international standards such as ISO 27001 gain a competitive edge by showcasing their dedication to best practices in information security management.

5. Business Continuity and Disaster Recovery:

Information security incidents can have severe consequences, leading to financial losses, operational disruptions, and damage to the company’s reputation. An ISMS encompasses business continuity planning and disaster recovery strategies to minimize the impact of such incidents. By implementing appropriate backup mechanisms, incident response protocols, and recovery procedures, companies can quickly restore operations and maintain the trust of stakeholders in the event of a security breach or a disruptive event.

An ISMS provides a comprehensive framework to protect sensitive information, comply with legal obligations, mitigate risks, build customer trust, and ensure business continuity. By implementing an ISMS, organizations can safeguard their valuable assets, keep and even enhance their reputation.
