Lateral movement is a technique used by cyber attackers to move within a network after an initial breach, looking for more valuable data and assets. It poses a significant threat to businesses as it can lead to larger security breaches. Technology managers need to be aware of lateral movement's risks and how compliance frameworks can help prevent such suspicious activities.

What is Lateral Movement?

Lateral movement refers to the process where attackers, once inside a network, move sideways (laterally) to explore and reach critical or sensitive data. The aim is to expand their foothold and escalate their privileges for more access. This movement often goes unnoticed because attackers mimic normal user behavior, making it hard to detect.

Why Compliance Frameworks Matter

Compliance frameworks are a set of rules and guidelines that help organizations maintain security standards. These frameworks ensure that businesses implement best practices to protect data and prevent unauthorized access.

Key Benefit: Compliance frameworks guide technology managers in setting up safeguards against lateral movement.
Improved Security: They prompt periodic checks and balances to tighten network security.
Industry Standards: Frameworks like NIST, ISO, or CIS are widely recognized and help you align with industry standards.

Steps to Prevent Lateral Movement with Compliance Frameworks

1. Know Your Network

Map all your network assets. Understand who has access to what and ensure permissions are on a need-to-know basis.

What: Segregate network segments to limit access.
Why: Reduces the chance for attackers to move laterally.
How: Use firewalls and access controls.

2. Monitor and Detect

Use monitoring tools to detect any unusual behavior. Automation can help identify patterns that seem out of place.

What: Implement threat detection systems.
Why: Early detection helps prevent serious breaches.
How: Regularly update threat detection tools.

3. Regular Audits and Testing

Conduct audits and vulnerability assessments frequently to ensure compliance with frameworks.

What: Schedule regular compliance checks.
Why: Ensures that security measures are always up-to-date.
How: Follow frameworks like NIST for guidelines.

4. Employee Training

Train employees to recognize phishing attempts and secure their access points.

What: Cybersecurity awareness programs.
Why: Reduces human error, a common entry point for attacks.
How: Use simulations for training.

Conclusion

Preventing lateral movement in your network is crucial to maintaining robust cybersecurity. Compliance frameworks provide the necessary guidelines to help organizations achieve this goal. By closely following these frameworks, technology managers can minimize the risk of unauthorized lateral movements.
