Many network security service providers include update and patch management as part of their offerings, simplifying this process for organizations and ensuring continuous protection.
3. Network Segmentation
Network segmentation divides a network into smaller, more manageable segments, isolating critical systems from less secure areas. This practice significantly reduces the attack surface.
Key approaches include:
- Creating Separate VLANs: Sensitive data and applications should reside in isolated Virtual Local Area Networks (VLANs).
- Restricting Access: Implement role-based access controls to ensure users only have access to the resources they need.
- Micro-Segmentation: This granular approach isolates workloads within the same network segment, minimizing lateral movement in the event of a breach.
By compartmentalizing network assets, segmentation ensures that even if one segment is compromised, the damage does not extend to the entire network.
4. Conduct Regular Vulnerability Assessments and Penetration Testing
Proactively identifying and addressing vulnerabilities is essential for a strong security posture. This involves:
- Vulnerability Scans: Regular scans detect weaknesses in network devices, applications, and systems.
- Penetration Testing: Ethical hackers simulate attacks to uncover exploitable vulnerabilities.
