This skill covers JIT architecture design, approval workflows, automatic expiration, integration with PAM and IGA platforms, and alignment with zero trust principles. ## When to Use - When deploying or configuring implementing just in time access provisioning capabilities in your environment - When establishing security controls aligned to compliance requirements - When building or improving security architecture for this domain - When conducting security assessments that require this implementation ## 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 JIT access request and approval workflows - Implement time-bound access grants with automatic expiration - Configure risk-based approval routing (auto-approve low-risk, multi-approval for high-risk) - Integrate JIT with PAM for privileged access elevation - Monitor and audit all JIT access grants and usage - Reduce attack surface by eliminating standing privileges ## Key Concepts ### JIT Access Models 1. **Broker and Remove**: Grant access through approval, auto-remove after time window 2. **Elevation on Demand**: User has base access, elevates to privileged upon request 3. **Account Creation/Deletion**: Temporary account created, destroyed after use 4. **Group Membership Toggle**: Add to privileged group temporarily, auto-remove ### Zero Standing Privilege (ZSP) Principle - No user has permanent privileged access - All privileged access requires explicit request with business justification - Access automatically expires after defined time window - All access events logged and auditable ## Workflow ### Step 1: Identify Eligible Access Types - Privileged admin access (domain admin, root, DBA) - Production environment access - Sensitive data access (PII, financial, healthcare) - Emergency/break-glass access - Third-party vendor access ### Step 2: Design Approval Workflows - Self-service request portal with justification requirement - Auto-approve for pre-authorized low-risk access (< 1 hour) - Single approver for medium-risk (manager or resource owner) - Dual approval for high-risk (manager + security team) - Emergency bypass with post-facto review ### Step 3: Implement Time-Bound Access - Configure maximum access duration per resource type - Implement countdown timer with extension request capability - Auto-revoke at expiration regardless of session state - Grace period notification (15 min before expiry) - Automatic session termination on access expiry ### Step 4: Integration Architecture - Connect to IAM/IGA platform for provisioning/de-provisioning - Integrate with PAM for privileged credential checkout - Connect to ITSM for ticket correlation - Forward events to SIEM for monitoring - API integration for programmatic access requests ### Step 5: Monitoring and Compliance - Log all JIT requests, approvals, grants, and revocations - Alert on access used beyond approved scope - Track access not used (request but never connected) - Measure mean time to access (request to grant) - Report on access patterns for baseline optimization ## Security Controls | Control | NIST 800-53 | Description | |---------|-------------|-------------| | Temporary Access | AC-2(2) | Automated temporary account management | | Least Privilege | AC-6 | Time-bound minimum access | | Access Enforcement | AC-3 | Automated access grant/revoke | | Audit | AU-3 | Complete JIT access audit trail | | Risk Assessment | RA-3 | Risk-based approval routing | ## Common Pitfalls - Setting time windows too long, negating JIT benefits - Not implementing automatic revocation at expiration - Complex approval workflows causing access delays for legitimate needs - Not providing emergency bypass for critical incidents - Failing to audit approved but unused JIT access ## Verification - [ ] JIT request workflow functional end-to-end - [ ] Access automatically revoked at expiration - [ ] Approval routing correct for all risk levels - [ ] Emergency access bypass works with post-review - [ ] All JIT events logged to SIEM - [ ] Standing privileges reduced by measurable percentage - [ ] Mean time to access meets business SLA ## Other files in this skill -

User submits access request via self-service portal 2. Request includes: target resource, duration, business justification 3. System calculates risk score based on resource sensitivity and user context 4. Risk-based routing: - Low risk (< 1 hr, non-privileged): Auto-approve - Medium risk: Route to resource owner for approval - High risk (privileged, production): Dual approval required 5. Approver notified via email/Slack/Teams 6. Approver reviews and approves/denies with comments 7. On approval: system provisions access with time-bound constraint 8. User notified of access grant with expiration time 9. At expiration: system automatically revokes access 10. All events logged for audit trail ## Workflow 2: Emergency JIT Access (Break-Glass) ### Steps: 1. User declares emergency and requests immediate access 2. System grants access immediately without pre-approval 3. Access limited to shorter maximum duration (e.g., 2 hours) 4. Security team notified of emergency access grant 5. User must provide justification within 24 hours 6. Manager and security team perform post-facto review 7. If review finds access unjustified: security incident opened 8. All emergency access events flagged in audit reports ## Workflow 3: Privileged Elevation with PAM Integration ### Steps: 1. User requests privilege elevation through JIT portal 2. Approval obtained per risk-based workflow 3. JIT system triggers PAM credential checkout 4. PSM session initiated with time-bound credential 5. User performs privileged operations via isolated session 6. Session recorded for audit 7. At expiration: session terminated, credential checked in, password rotated 8. JIT access record closed ## Workflow 4: Vendor/Third-Party JIT Access ### Steps: 1. Internal sponsor submits access request on behalf of vendor 2. Request includes: vendor identity, scope, duration, project reference 3. Dual approval required (sponsor manager + security) 4. Temporary account created with MFA enrollment 5. Access restricted to specified resources only 6. Network access limited to authorized segments 7. Session monitoring enabled 8. Account deactivated at expiration 9. Account deleted after 30-day retention period Back to [[skills-anthropic-cybersecurity-skills]] or [[agent-skills]].
