Protecting access to Microsoft Active Directory is important when MTG PKI is integrated with an AD environment. Appropriate security measures include:
VPN (Virtual Private Network): Use encrypted network connections to protect administrative and system access.
Multi-Factor Authentication (MFA): Require additional authentication factors for privileged and administrative access.
Network Access Control (NAC): Control network access based on user, device, and security criteria.
Segmentation and microsegmentation: Separate critical systems and restrict access between network zones.
Least Privilege: Grant users and service accounts only the permissions they require for their tasks.
Monitoring and logging: Monitor security-relevant activity and integrate logs into SIEM systems where appropriate.
Hardened AD servers: Apply secure configuration standards, remove unnecessary services, and install security updates regularly.
Combining these measures can significantly improve the security of Active Directory and the overall PKI environment.
