Conducting regular security assessments and audits in a Privileged Access Management (PAM) environment, such as CyberArk, is critical to identifying vulnerabilities and ensuring security compliance. Here’s how you can approach this:
1. Define Audit Scope and Frequency
* Determine scope: Identify which systems, privileged accounts, access policies, and components of the PAM environment (e.g., vault, session manager, audit logs) are to be reviewed.
* Frequency: Set a regular schedule (e.g., monthly, quarterly, or after significant changes) for assessments and audits based on the risk profile of the organization.
2. Review and Audit Privileged Accounts
• Discovery and Inventory: Use automated tools to regularly discover and document all privileged accounts in the environment. Validate that all accounts in use are authorized.
• Account Onboarding: Review whether newly onboarded privileged accounts follow the appropriate security policies (e.g., password complexity, rotation, least privilege access).
• Orphaned Accounts: Identify any orphaned or unused privileged accounts that may present a security risk, and disable or remove them.
3. Examine Access Policies and Role-Based Controls
• Policy Review: Regularly review role-based access control (RBAC) policies to ensure that access levels are assigned appropriately. Ensure that the principle of least privilege is enforced.
• Multi-Factor Authentication (MFA): Verify that MFA is properly implemented for all privileged users to enhance access security.
• Access Approval Process: Ensure there’s an audit trail for access approvals and changes made to privileges or roles.
4. Evaluate Password Management
• Password Rotation: Check that privileged account passwords are rotated regularly in line with policy. Verify automated rotation processes for compliance.
• Password Vaulting: Ensure passwords and credentials stored in the vault are securely encrypted and only accessible to authorized users.
5. Review Privileged Session Management (PSM)
• Session Recording: Ensure all privileged sessions are being recorded and monitored. Check the configuration of Privileged Session Manager (PSM) for full session isolation and real-time monitoring.
• Session Audit: Periodically review session logs for suspicious activity or unauthorized access. Investigate any anomalies or unapproved access attempts.
6. Conduct Vulnerability Scans and Penetration Tests
• Automated Vulnerability Scanning: Perform vulnerability scans to identify weaknesses in the PAM infrastructure (e.g., unpatched software, misconfigurations).
• Penetration Testing: Regularly perform penetration testing of the PAM system to simulate real-world attacks and test the effectiveness of security controls, particularly around privileged access.
7. Analyze Privileged Threat Analytics (PTA)
• Behavioral Analytics: Use CyberArk’s PTA or similar tools to monitor privileged account activity for anomalies. Audit alerts generated by PTA for abnormal behavior such as unusual login times, unauthorized access, or lateral movement attempts.
• Incident Response Review: Evaluate incident response capabilities in the event of a detected threat. Ensure that logs are reviewed promptly and actions are taken to mitigate any identified risks.
8. Audit and Review Activity Logs
• Log Retention: Ensure that audit logs for privileged activity (access, password retrieval, session logs) are properly stored and retained according to compliance requirements.
• Log Review: Conduct periodic reviews of logs to detect any unauthorized or suspicious activity. Automate the analysis where possible to identify trends or vulnerabilities early.
9. Compliance and Security Policy Review
• Policy Adherence: Verify that the PAM environment aligns with industry standards and regulatory requirements (e.g., ISO 27001, PCI DSS, GDPR).
• Security Policies: Regularly update PAM security policies based on audit findings, new vulnerabilities, and evolving threat landscapes.
10. Prepare Audit Reports and Remediation Plans
• Audit Reporting: Document findings from the assessments, including any detected vulnerabilities, and prioritize based on risk.
• Remediation Plans: Develop and implement remediation plans for any security gaps or weaknesses found during the audit. Assign responsibility and deadlines for completing these actions.
• Follow-Up Audits: Conduct follow-up assessments to ensure remediation efforts were successful and that new vulnerabilities haven’t emerged.
Conclusions:-
Regular security assessments and audits help maintain the integrity of the PAM environment and ensure that privileged accounts are well-protected against evolving cybersecurity threats.
