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.

NIS2: 2.Designate a responsible person or team

/in

We wrote here https://www.sorinmustaca.com/how-to-nis2-eu-directive/ that the second step in implementing NIS2 requirements is to designate a responsible person or team.

Appointing an individual or a team responsible for overseeing the implementation of the NIS2 directive within your company is critical to ensure its success.

NIS2 implementation and compliance is a project, and as any project must have a dedicated team that is actively working on its implementation.

Due to the fact that the the NIS2 requirements are demanding a continuous activity, there must be a continuity of the project after its implementation. This means that there has to be a team appointed to this project that is responsible for continuously monitoring and adapting the activities required for NIS2 compliance. To effectively manage these challenges, companies should establish a new dedicated team or name an existing team to be responsible for cybersecurity and compliance.

In this article, we will explore the reasons behind the need for such a team and identify existing teams within a company that could take on these vital responsibilities.

Cyber threats are constantly evolving, becoming more sophisticated and persistent. From data breaches and ransomware attacks to regulatory changes, companies are exposed to a multitude of risks that can have significant consequences.

Here’s why a dedicated cybersecurity and compliance team is essential:

  1. Proactive Threat Mitigation: A dedicated team can stay ahead of emerging threats by continuously monitoring the threat landscape, analyzing vulnerabilities, and implementing proactive security measures. They can assess potential risks and ensure that the company is well-prepared to defend against cyberattacks.
  2. Regulatory Compliance: Compliance with industry-specific regulations (ISO 27001, TISAX, ISO 21434) and data protection laws (such as GDPR or HIPAA) is a legal requirement. A dedicated team can ensure that the company adheres to these regulations, avoiding costly fines and legal repercussions.
  3. Incident Response: In the unfortunate event of a cybersecurity breach, a well-prepared team can swiftly respond to contain the damage, investigate the incident, and minimize the impact on the business and its customers.

 

Good news: existing teams can take on cybersecurity and compliance roles!

Identifying the right team to assume the responsibility of cybersecurity and compliance is crucial.

Below are some existing teams within a company that could take on these roles. However, be aware that due to the complex nature of the task, most chances of success has an interdisciplinary team.

 

  • IT Department: IT professionals are typically responsible for managing the company’s technology infrastructure. They can play a critical role in implementing security measures, monitoring networks, and ensuring that software and hardware are up to date with security patches.

Be aware, the IT teams may not have the specialized expertise needed for compliance and may benefit from additional support. With the right people on board, they can take over this critical task.

 

  • Legal and Compliance Teams: Legal and compliance departments are already well-versed in navigating complex regulatory frameworks. They can take on the compliance aspect of cybersecurity, ensuring that the company aligns with industry-specific laws and regulations.

L&C teams may require additional cybersecurity expertise to address the technical aspects of protection.

 

  • Dedicated Cybersecurity Team: For companies with significant digital assets and a higher level of exposure to cyber threats, establishing a dedicated cybersecurity team is advisable.

This team would focus exclusively on safeguarding the company’s digital assets, monitoring threats, conducting penetration testing, and developing comprehensive cybersecurity policies and strategies.

 

  • Cross-Functional Cybersecurity Team: In some cases, it may be beneficial to establish a cross-functional committee that includes representatives from various departments, including IT, legal, compliance, and risk management.

This team can collaborate to address cybersecurity and compliance challenges effectively.

 

Important activities that must be performed for NIS2 compliance

As part of the NIS2 requirements, the team responsible make sure that these activities are performed.

However, due to the fact that so many areas are involved, it is quite clear that the entire company must be involved.

 

  1. Risk Assessment and Management:
    • Identifying and assessing cybersecurity risks and vulnerabilities across the organization.
    • Developing risk mitigation strategies and prioritizing security measures based on the level of risk.

How-To: NIS2 EU Directive

/in

The NIS2 Directive is a European Union legislative text on cybersecurity that supersedes the first NIS (Network and Information Security) Directive, adopted in July 2016.

NIS vs. NIS2

While the first NIS (Network and Information Security) Directive increased the Member States’ cybersecurity capabilities, its implementation proved difficult, resulting in fragmentation at different levels across the internal market. To respond to the growing threats posed with digitalisation and the surge in cyber-attacks, the Commission has submitted a proposal to replace the NIS Directive and thereby strengthen the security requirements, address the security of supply chains, streamline reporting obligations, and introduce more stringent supervisory measures and stricter enforcement requirements, including harmonised sanctions across the EU.

NIS2 strengthens security requirements in the EU by expanding the NIS scope to more sectors and entities, taking into account

  • the security of supply chains,
  • streamlining reporting obligations,
  • introducing monitoring measures,
  • introducing more stringent enforcement requirements,
  • adding the concept of “management bodies” accountability within companies, and
  • harmonizing and tightening sanctions in all Member States.

To achieve the above mentioned goals, NIS2 requires member states to take a number of measures that forces them to work together:

  • Establish or improve information sharing between member states and a common incident response plan that coordinates with other member state plans
  • Establish a national Computer Emergency Response Team
  • Strengthen cooperation between public and private sector entities

 

In a nutshell, companies can stay compliant with the NIS2 Directive by

  • establishing an effective monitoring system that can detect intrusions, detect suspicious activities, and alert the authorities when necessary
  • developing comprehensive plans that detail how they will respond to an attack and what steps they will take to recover from it.

 

The official website of the EU for the NIS2 Directive has prepared an FAQ with many good questions and answers.

However, what the website is not saying (for good reasons) is how should companies start to prepare for implementing the directive.

 

How to start the compliance path

In order to successfully start implementing the requirements, the following steps should be implemented in this order. We will publish articles about pretty much each of these topics.

 

1.Conduct a gap analysis

Assess your company’s current cybersecurity practices, policies, and infrastructure against the requirements of the NIS2 directive.

Identify any gaps or areas that need improvement to comply with the directive.

Dedicated article:  https://www.sorinmustaca.com/nis2-1-perform-a-gap-analysis/

 

2.Designate a responsible person or team

Appoint an individual or a team responsible for overseeing the implementation of the NIS2 directive within your company. This could be a dedicated cybersecurity team or an existing department with relevant expertise.

Dedicated article: https://www.sorinmustaca.com/nis2-2-designate-a-responsible-person-or-team/

 

3.Establish a cybersecurity framework

Develop or update your company’s cybersecurity framework to align with the NIS2 directive. This framework should include policies, procedures, and technical controls to protect your network and information systems effectively.

Dedicated article: https://www.sorinmustaca.com/nis2-3-establish-a-cybersecurity-framework/

 

4.Perform a risk assessment

Conduct a comprehensive risk assessment of your company’s network and information systems. Identify potential threats, vulnerabilities, and risks that may impact the availability, integrity, and confidentiality of critical systems and data. This assessment will help you prioritize security measures and allocate appropriate resources. Risk management and assessments are an ongoing process. Once one risk assessment is carried out, it is important to schedule regular updates to ensure all steps are maintained.

Dedicated article: https://www.sorinmustaca.com/nis2-perform-a-risk-assessment/

 

5.Implement security measures

Based on the risk assessment findings, implement appropriate security measures to mitigate identified risks. This may include network segmentation, access controls, intrusion detection systems, incident response procedures, encryption, employee training, and regular security updates, among others.

Dedicated article:

 

6.Establish incident response capabilities

Develop an incident response plan and establish procedures for detecting, responding to, and recovering from cybersecurity incidents. Ensure the assigned employees are trained on how to recognize and report security breaches promptly. Business continuity is a very complex topic, which must be planned with a lot of time in advance and it requires extra resources (both human and financial).

Dedicated article:

 

7.Continuously Monitor and review

Implement mechanisms to continuously monitor and assess your network and information systems for potential threats. Regularly review and update your cybersecurity measures to adapt to emerging risks and changes in the threat landscape.

Dedicated article:

 

8. Maintain documentation and records

Keep comprehensive documentation of your cybersecurity measures, risk assessments, incident response activities, and any other relevant information. This documentation will serve as evidence of compliance and may be required for regulatory audits or investigations. A good record might save your company legal and regulatory repercussions in case of a major incident (cyber related or not).

Dedicated article:

 

9.Engage with regulatory authorities

Stay informed about any reporting or notification obligations outlined in the NIS2 directive. Establish communication channels with the relevant regulatory authorities and comply with any reporting requirements or inquiries they may have. NIS2 strives to improve EU-wide communication and sharing of cyber events in order to better prepare answers and reactions. Communication has never been more important than now.

Dedicated article:

 

10. Define KPIs for cybersecurity and measures taken based on them

In order to measure the effectiveness of the cybersecurity, you need to define metrics that allow identifying and quantifying changes. Example of metrics are number of incidents, types of incidents,  how many trainings have been made, how many people were trained, how many pentests were made and how many issues were identified, and many more.
