# 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
**Trigger phrases:**
- "performing privileged account access review"
- "Conduct systematic reviews of privileged accounts to validate access rights, ide"


- 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

This section covers core concepts for performing privileged account access review.

- Ensure all prerequisites are met before proceeding
- Follow the documented workflow steps in sequence
- Record results and any anomalies encountered during this phase
### 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

1. **Scope the task** — define objectives, boundaries, and success criteria
2. **Gather information** — collect all necessary data and context before proceeding
3. **Execute the core workflow** — follow the domain-specific steps methodically
4. **Validate results** — verify outputs against expected outcomes or baselines
5. **Document findings** — record results, anomalies, and recommendations
### 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

## When NOT to Use

- You don't have explicit written authorization to test
- Task is about defense/detection, not offense (use detection skills)
- You need to implement security controls (use implementing-* skills)
- Task requires compliance auditing (use auditing-* skills)
- You're investigating an incident (use incident response skills)
- Target is out of scope for your engagement
- Task is about vulnerability scanning only (use scanning tools)


## Red Flags

- Performing actions without explicit written authorization from the asset owner
- Testing against production systems without a defined scope and rules of engagement
- Sharing sensitive findings or credentials in unencrypted communications
- Failing to properly scope and contain the assessment before starting

## Verification

- All steps executed successfully against a test environment before production use
- Output documented with screenshots or logs demonstrating expected behavior
- Results validated against known-good baselines or reference implementations
- Documentation complete enough for another analyst to reproduce findings

## Process

1. Analyze the task requirements
2. Apply domain expertise
3. Verify output quality

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
