# Performing Access Review and Certification

## Overview
Conduct systematic access reviews and certifications to ensure users have appropriate access rights aligned with their roles. This skill covers review campaign design, reviewer selection, risk-based prioritization, micro-certification strategies, and remediation tracking for compliance with SOX, HIPAA, and PCI DSS requirements.


## When to Use

- When conducting security assessments that involve performing access review and certification
- 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

- Familiarity with identity access management concepts and tools
- Access to a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities

## Objectives
- Design and execute access review campaigns across enterprise applications
- Implement risk-based prioritization for review scope
- Configure reviewer selection (manager, application owner, hybrid)
- Automate entitlement data collection and presentation
- Track remediation of inappropriate access findings
- Generate compliance evidence for auditors

## Key Concepts

### Access Review Types
1. **User Access Review**: Manager certifies all entitlements for their direct reports
2. **Entitlement Review**: Application owner certifies all users with specific entitlement
3. **Role Review**: Role owner certifies role membership and permissions
4. **Privileged Access Review**: Security team reviews high-risk/privileged access
5. **SOD Review**: Verify no users have conflicting separation-of-duty violations

### Risk-Based Prioritization
- **High Risk**: Privileged access, financial systems, PII/PHI systems, external-facing apps
- **Medium Risk**: Internal business applications, shared drives, collaboration tools
- **Low Risk**: Standard employee tools, read-only access, public information systems

### Review Campaign Lifecycle
1. **Planning**: Define scope, reviewers, timeline, escalation
2. **Data Collection**: Aggregate entitlements from all identity sources
3. **Distribution**: Assign review items to appropriate certifiers
4. **Certification**: Reviewers approve or revoke each entitlement
5. **Remediation**: Revoke inappropriate access, enforce timeline
6. **Reporting**: Generate compliance evidence and metrics
7. **Closure**: Archive campaign, feed findings into next cycle

## Workflow

### Step 1: Define Review Scope and Schedule
- Identify in-scope applications and systems
- Determine review frequency: quarterly (SOX), semi-annual, annual
- Define campaign timeline: review period, escalation dates, hard close
- Establish escalation chain for non-responsive reviewers

### Step 2: Data Collection and Aggregation
- Extract user-entitlement mappings from each application
- Correlate with HR data (active employees, role, department, manager)
- Identify terminated/transferred users still holding access
- Flag high-risk entitlements (admin, DBA, system, privileged)
- Calculate risk scores based on entitlement sensitivity and user role

### Step 3: Reviewer Assignment
- **Manager Reviews**: Direct manager certifies subordinate access
- **Application Owner Reviews**: App owner certifies all users of their application
- **Hybrid Model**: Manager reviews standard access, app owner reviews privileged
- **Delegate Management**: Allow reviewers to delegate with audit trail

### Step 4: Execute Certification Campaign
- Send notifications to reviewers with clear instructions
- Present entitlements with context (last used date, risk level, role justification)
- Require reviewers to explicitly approve or revoke each item
- Track completion percentage and send reminders
- Escalate to management after deadline

### Step 5: Remediation and Tracking
- Automatically ticket revocations to IT operations
- Set SLA for revocation execution (24-48 hours for high-risk)
- Verify revocation completed (re-check entitlement)
- Exception management for business-justified deviations
- Document all exceptions with expiration dates

### Step 6: Reporting and Evidence
- Generate campaign completion metrics
- Produce per-application compliance reports
- Create audit-ready evidence packages
- Track trends across review cycles
- Feed findings into risk assessment process

## Security Controls
| Control | NIST 800-53 | Description |
|---------|-------------|-------------|
| Access Review | AC-2(3) | Periodic review of account privileges |
| Account Management | AC-2 | Account lifecycle management |
| Least Privilege | AC-6 | Minimum necessary access enforcement |
| Separation of Duties | AC-5 | SOD conflict identification |
| Audit Logging | AU-6 | Review of access audit records |

## Common Pitfalls
- Rubber-stamping: reviewers approving all access without examination
- Incomplete scope: missing critical applications from review campaigns
- No remediation tracking: revoking access on paper but not in systems
- Inconsistent reviewer assignment causing gaps in coverage
- Not including service accounts and non-human identities

## Verification
- [ ] All in-scope applications included in campaign
- [ ] Reviewers assigned for 100% of entitlements
- [ ] Campaign completion rate exceeds 95%
- [ ] Revocations executed within SLA
- [ ] Audit evidence package complete and archived
- [ ] SOD violations identified and documented
- [ ] Exceptions documented with business justification and expiry

# Access Review and Certification Workflows

## Workflow 1: Quarterly Access Review Campaign

### Timeline:
- Week 1: Data collection and campaign configuration
- Week 2-4: Active review period
- Week 5: Escalation for non-responsive reviewers
- Week 6: Hard close and remediation initiation
- Week 7-8: Remediation execution and verification
- Week 8: Campaign closure and reporting

### Steps:
1. Extract entitlement data from all in-scope systems
2. Correlate with HR data for active/inactive status
3. Calculate risk scores for each user-entitlement pair
4. Assign reviewers based on reviewer model
5. Launch campaign with notifications
6. Monitor completion daily, send reminders at 50% and 75% of timeline
7. Escalate to VP level at deadline for incomplete reviews
8. Force-close with auto-revoke or manager-override at hard deadline
9. Process revocations through ticketing system
10. Verify revocations completed in target systems
11. Generate compliance report and evidence package

## Workflow 2: Triggered Access Review (Role Change)

### Steps:
1. HR system notifies of employee role change (transfer, promotion)
2. System identifies current access vs. new role entitlements
3. Birthright access for new role automatically provisioned
4. Legacy access flagged for new manager review
5. New manager certifies which legacy access to retain/revoke
6. Retained access documented with justification
7. Revoked access removed within SLA

## Workflow 3: Privileged Access Micro-Certification

### Steps:
1. Weekly extraction of privileged entitlements
2. Privileged access grouped by system owner
3. System owner reviews new privileged access grants since last certification
4. Each privileged entitlement requires explicit approval with justification
5. Non-certified privileged access auto-revoked after 48 hours
6. Results forwarded to security team for trending

## Workflow 4: SOD Violation Detection and Resolution

### Steps:
1. Define SOD rule matrix (e.g., AP create vs. AP approve)
2. Scan entitlements against SOD rules
3. Flag violations with risk level
4. Route violations to compliance team
5. Compliance team evaluates: revoke access or approve compensating control
6. If compensating control: document control, set review frequency, assign monitor
7. If revoke: process access removal and verify
