All procedures documented and tested quarterly.
- Updates: Identity records updated within 24 hours of any change (name, role, access permissions). Identity validation systems updated monthly with security patches and quarterly with feature updates. Identity validation algorithms reviewed annually.
- Revocation: Identity credentials revoked immediately upon: employee termination, security incident, role change requiring access removal, or suspected compromise. Revocation completed within 15 minutes and all systems notified within 1 hour.
- Verification: Multiple verification points required for all transactions, including: transaction origin verification (source IP, device fingerprint, user identity), transaction content verification (amount, recipient, purpose), transaction authorization verification (approval chain, limits), and transaction integrity verification (digital signature, hash validation). All verifications completed within 3 seconds.
- Authorization: Transaction authorization required based on transaction type and amount: transactions under $10,000 require single authorized approver, transactions $10,000-$100,000 require dual authorization, transactions over $100,000 require SCC approval. Authorization must be documented with timestamp, approver identity, and approval rationale.
- Recording: Permanent recording of all transactions in tamper-evident audit logs with cryptographic integrity protection. Records include: transaction ID, timestamp, parties, amount, purpose, authorization chain, validation results, and system state. Records retained for minimum 10 years or as required by applicable law.
- Monitoring: Ongoing monitoring of all transactions through real-time fraud detection systems, anomaly detection algorithms, and pattern analysis. Suspicious transactions flagged within 30 seconds and escalated to Security Department. Monitoring reports generated daily and reviewed weekly.
- Testing: Regular testing of all validation systems including: unit testing (before deployment), integration testing (monthly), penetration testing (quarterly), and disaster recovery testing (annually). All tests documented with results, findings, and remediation actions. Test coverage must exceed 90% for critical systems.
- Auditing: Ongoing auditing of validation systems through automated audit tools, manual audits (quarterly), and external audits (annually). Audits verify: system functionality, security controls, compliance with specifications, and operational effectiveness. Audit findings addressed within 30 days.
- Certification: System certification required before production deployment, including: security certification (NIST 800-53 controls), cryptographic certification (FIPS 140-2 Level 3 or higher), and operational certification (performance, reliability, availability). Re-certification required annually or after significant changes.
- Compliance: All validation systems must comply with: CSP-1113 Technical Specification, NIST 800-53 Security Controls, Title X Security requirements, and Technical Standards. Compliance verified through automated compliance monitoring, quarterly compliance reviews, and annual compliance audits.
- Activation: Incident response activated automatically upon detection of: critical security events (unauthorized access, data breach, system compromise), system failures affecting operations, or manual activation by authorized personnel. Activation must occur within 5 minutes of detection. Activation triggers notification of Incident Response Team, Security Department, and Executive Directorate.
- Roles: Defined roles for incident response including: Incident Commander (Security Director or designee), Technical Lead (Technical Director or designee), Communications Lead (Communications Director or designee), Legal Advisor (Legal Director or designee), and Executive Sponsor (Executive Director). Roles and responsibilities documented in Incident Response Plan and updated annually.
- Communication: Communication protocols established in Incident Response Plan, including: internal notifications (within 15 minutes to Incident Response Team, within 30 minutes to Executive Directorate, within 1 hour to SCC for critical incidents), external notifications (as required by law or regulation, within 72 hours for data breaches), and public communications (coordinated through Communications Department with Legal Department approval). All communications documented.
- Documentation: Required documentation for all incidents includes: incident report (within 24 hours), timeline of events, actions taken, systems affected, data compromised (if any), remediation steps, and lessons learned. Documentation maintained in secure incident management system and retained for minimum 7 years.
- Triggers: Automatic failover triggers include: primary system failure (hardware, software, network), performance degradation exceeding thresholds (response time >5 seconds, availability <99.9%), security incidents requiring isolation, or manual activation by authorized personnel. Triggers configured in failover management systems and tested quarterly.
- Activation: Failover activation occurs automatically within 30 seconds of trigger detection, or manually within 2 minutes of manual activation request. Activation process includes: verification of backup system readiness, data synchronization verification, service migration, and validation of backup system operation. Activation documented with timestamp, trigger, and system state.
- Validation: Post-failover validation required within 5 minutes of activation, including: system functionality verification, data integrity verification, performance verification, security verification, and user access verification. Validation results documented and reviewed. If validation fails, additional remediation required before declaring failover successful.
- Recovery: Return to primary systems occurs after: primary system restoration, validation of primary system functionality, data synchronization verification, and approval from Technical Director. Recovery process includes: gradual migration of services, validation at each step, and final cutover. Recovery completed within 4 hours during business hours or 8 hours during off-hours. Recovery documented with timeline and validation results.
- Internal: Regular internal audits conducted quarterly by Internal Audit Department, covering: security controls effectiveness, compliance with policies and procedures, system configurations, access controls, and incident response procedures. Internal audit reports submitted to Executive Directorate and SCC within 30 days of completion.
- External: Annual external audits conducted by independent certified security auditors (CISSP, CISA, or equivalent), covering: comprehensive security assessment, compliance with NIST 800-53, penetration testing, vulnerability assessment, and security architecture review. External audit reports submitted to SCC within 60 days of completion.
- Special: Special audits conducted as required by: security incidents requiring investigation, regulatory requirements, SCC requests, or Executive Directorate directives. Special audits must be completed within 30 days of initiation and results reported to requesting authority within 10 days of completion.
- Continuous: Ongoing monitoring through automated security monitoring systems, including: real-time log analysis, intrusion detection, vulnerability scanning, configuration monitoring, and compliance monitoring. Continuous monitoring results reviewed daily by Security Department and reported weekly to Executive Directorate.
