Performing Privileged Account Access Review

Overview

Privileged Account Access Review is a critical identity governance process that validates whether users with elevated permissions still require their access. This review covers domain admins, service accounts, database administrators, cloud IAM roles, and application-level privileged accounts. Regular access reviews are mandated by SOC 2, PCI DSS, HIPAA, and SOX compliance frameworks, typically required quarterly for high-privilege accounts.

When to Use

• When conducting security assessments that involve performing privileged account access review
• When following incident response procedures for related security events
• When performing scheduled security testing or auditing activities
• When validating security controls through hands-on testing

Prerequisites

• PAM solution deployed (CyberArk, BeyondTrust, Delinea, or equivalent)
• Identity governance platform (SailPoint, Saviynt, or equivalent)
• Complete inventory of privileged accounts across all platforms
• Defined access review policy with SLAs and escalation procedures
• Designated reviewers (account owners, managers, security team)

Core Concepts

Privileged Account Categories

Category	Examples	Risk Level	Review Frequency
Domain Admins	Enterprise Admin, Domain Admin, Schema Admin	Critical	Monthly
Service Accounts	SQL service, backup agents, monitoring agents	High	Quarterly
Cloud IAM	AWS root, Azure Global Admin, GCP Owner	Critical	Monthly
Database Admin	DBA accounts, sa/sys accounts	High	Quarterly
Application Admin	App admin roles, API keys with admin scope	Medium	Semi-annually
Emergency/Break-glass	Firecall accounts, emergency access	Critical	After each use

Workflow

Step 1: Account Discovery and Inventory

Enumerate all privileged accounts across the environment:

Active Directory:

• Domain Admins, Enterprise Admins, Schema Admins groups
• Accounts with AdminCount=1 attribute
• Service accounts with SPN (Service Principal Names)
• Accounts with delegation rights (Unconstrained/Constrained)

Cloud Platforms:

• AWS: IAM users/roles with AdministratorAccess, PowerUserAccess, or iam:* permissions
• Azure: Global Administrator, Privileged Role Administrator, Security Administrator roles
• GCP: Owner, Editor roles at organization/project level

Databases:

• SQL Server: sysadmin, db_owner, securityadmin fixed roles
• Oracle: DBA, SYSDBA, SYSOPER privileges
• PostgreSQL: superuser, createrole, createdb attributes

Step 2: Establish Review Criteria

Each privileged account must be evaluated against:

1. Business Justification: Does the user's current role require this privilege?
2. Least Privilege: Can the task be performed with lower privileges?
3. Account Activity: Has the account been active in the last 90 days?
4. Compliance Status: Does the account meet password policy, MFA requirements?
5. Separation of Duties: Does the access create SoD conflicts?
6. Ownership: Is a responsible owner assigned and active?

Step 3: Conduct the Review

For each account, the designated reviewer must:

1. Review the account details, permissions, and last activity date
2. Approve (certify) the access if still required with documented justification
3. Revoke access if no longer needed or the reviewer cannot justify the privilege
4. Flag for investigation if anomalous activity or policy violations are detected
5. Escalate if the reviewer cannot make a determination

Decision matrix:

Condition	Action
Active user, justified privilege	Certify - maintain access
Active user, excessive privilege	Remediate - reduce to least privilege
Inactive > 90 days	Disable account, notify owner
No owner identified	Disable account, escalate to security
SoD conflict detected	Remediate - reassign or add compensating controls
Break-glass account	Verify last use was authorized, reset credentials

Step 4: Remediation and Enforcement

After reviews are completed:

• Revoke access for accounts that were not certified within the SLA period
• Implement automatic revocation for accounts not reviewed within 14 days
• Rotate credentials for all certified privileged accounts
• Convert standing privileges to just-in-time (JIT) access where possible
• Update PAM vault with current account inventory

Step 5: Reporting and Documentation

Generate review reports including:

• Total accounts reviewed vs. total in scope
• Certification rate (approved vs. revoked)
• Average review completion time
• Overdue reviews and escalations
• Remediation actions taken
• Comparison with previous review cycle

Validation Checklist

• Complete inventory of all privileged accounts documented
• All accounts assigned to a responsible owner/reviewer
• Review criteria and decision matrix defined
• Reviewers completed certification within SLA (14 days)
• Revoked accounts disabled and credentials rotated
• Orphaned accounts identified and disabled
• Service accounts reviewed for least privilege
• Break-glass accounts audited for authorized use only
• Review report generated with metrics and trends
• Remediation tickets created and tracked to completion
• Evidence preserved for compliance audit
