AD CS monitoring and detection involves implementing systems and processes to continuously observe, analyze, and alert on activities within your Active Directory Certificate Services infrastructure, helping to identify potential security threats and anomalies.

• Enables early detection of potential security incidents
• Helps identify misconfigurations and vulnerabilities
• Supports compliance with security standards and regulations
• Provides valuable data for incident response and forensics
• Enhances overall security posture of the AD CS environment

1. Enable Comprehensive Logging

   Configure detailed logging for all AD CS components and related systems.

   Copy command

   auditpol /set /subcategory:"Certification Services" /success:enable /failure:enable

2. Implement a SIEM Solution

   Deploy a Security Information and Event Management (SIEM) system to centralize log collection and analysis.

3. Configure Real-time Monitoring

   Set up continuous monitoring of critical AD CS components and activities.

   Copy command

   wevtutil sl Microsoft-Windows-CertificateServicesClient-Lifecycle-System/Operational /e:true

4. Develop Custom Detection Rules

   Create specific rules to detect known AD CS attack patterns and anomalies.

5. Establish an Alerting System

   Configure alerts for critical events and potential security incidents.

6. Implement Regular Auditing

   Conduct periodic reviews of AD CS configurations, permissions, and activities.

   Copy command

   certutil -setreg CA\AuditFilter 127

• Implement the principle of least privilege for all AD CS components
• Regularly update and patch all AD CS servers and related systems
• Conduct regular security assessments and penetration testing
• Implement network segmentation to isolate AD CS components
• Develop and maintain an incident response plan specific to AD CS-related incidents
