Network Segmentation is a core foundational cybersecurity concept that every cybersecurity and GRC professional should understand.
What Is Network Segmentation?
Network Segmentation refers to the practices, processes, or technologies related to network segmentation within the context of information security and risk management. Understanding network segmentation helps organizations protect their systems, data, and operations from relevant threats.
How It Works
Network Segmentation is applied through a combination of policies, technical controls, and organizational procedures. Security teams implement network segmentation as part of a broader security program aligned to industry frameworks and regulatory requirements.
Why It Matters
Organizations that correctly implement network segmentation reduce their exposure to cyber risk, improve regulatory compliance, and strengthen their overall security posture.
Key Takeaways
- Understand what network segmentation is and how it applies to your organization’s security program.
- Align network segmentation practices to a recognized framework such as NIST CSF, ISO 27001, or CIS Controls.
- Regularly review and test controls related to network segmentation to ensure they remain effective as threats evolve.
