Cybersecurity Framework Overview¶
Section: Document 4A — Cybersecurity Framework & Operations
Focus: Security frameworks, compliance standards, and SOC operations
Section Purpose¶
This section provides the comprehensive cybersecurity framework implementation for enterprise security operations, detailing operational procedures, control implementations, and continuous monitoring practices aligned with industry best practices.
Primary Frameworks Covered: - NIST Cybersecurity Framework 2.0 - CIS Critical Security Controls v8 - MITRE ATT&CK Enterprise Matrix - ISO 27001:2022
Chapter Overview¶
1. Executive Summary¶
Security architecture overview, threat landscape assessment, compliance requirements, and success metrics.
Key Content: - Integrated security platform stack (10+ platforms) - Defense-in-depth architecture - Threat landscape for financial services - Compliance requirements (PCI-DSS, SOC 2, GDPR, ISO 27001) - Current vs. target security metrics (MTTD, MTTR, false positives)
2. NIST Cybersecurity Framework 2.0¶
Complete implementation of NIST CSF 2.0 across all six functions.
Functions Covered: - GOVERN (GV) — Organizational context, risk management, oversight - IDENTIFY (ID) — Asset management, risk assessment - PROTECT (PR) — Identity management, data security, platform security - DETECT (DE) — Anomaly detection, continuous monitoring - RESPOND (RS) — Incident management, analysis, mitigation - RECOVER (RC) — Recovery planning, communications
3. CIS Critical Security Controls v8¶
Implementation of all 18 CIS Controls with platform mapping.
Implementation Groups: - IG1 (Basic Cyber Hygiene) — Baseline for all systems - IG2 (Enterprise) — Target baseline for Abhavtech - IG3 (Advanced) — Critical systems only
Control Mapping: - CIS 1-6: Foundation controls (inventory, configuration, access) - CIS 7-13: Security operations controls (vuln mgmt, monitoring, defense) - CIS 14-18: Advanced controls (training, incident response, pen testing)
4. MITRE ATT&CK Framework¶
Coverage analysis and detection mapping for Enterprise ATT&CK Matrix.
Content: - 14 tactics, 200+ techniques coverage analysis - Current coverage: 68% (target: 80% by EOY 2026) - Top 20 techniques deep dive with detection methods - ATT&CK Navigator heatmap (JSON export)
5. ISO 27001:2022 Controls¶
Complete ISO 27001:2022 controls mapping with audit evidence.
Control Categories: - Organizational controls (37 controls) - People controls (8 controls) - Physical controls (14 controls) - Technological controls (34 controls)
6. SOC Operations¶
24x7 Security Operations Center procedures and workflows.
Content: - SOC organization (12 analysts, follow-the-sun model) - Daily operations workflow - Alert triage process and escalation matrix - Incident response playbooks (PB-001 to PB-008) - Threat hunting program
7. Incident Response¶
Detailed incident response playbooks and procedures.
Playbooks: - PB-001: Malware Containment (fully automated) - PB-002: Compromised Credential (fully automated) - PB-003: Lateral Movement (semi-automated) - PB-004: Data Exfiltration (semi-automated) - PB-005: Ransomware Response (fully automated) - PB-006: Impossible Travel (fully automated) - PB-007: Phishing Response (manual) - PB-008: DDoS Mitigation (semi-automated)
8. Compliance¶
Compliance reporting, audit procedures, and regulatory requirements.
Coverage: - PCI-DSS v4.0 compliance - SOC 2 Type II attestation - GDPR requirements - Quarterly risk assessments - Annual external audits
Target Audience¶
Primary: Security Operations Center (SOC), Security Engineers, Compliance Team, CISO
Secondary: IT Operations, Network Engineers, Executive Management
Integration Points¶
This framework integrates with: - Network Forensics — Incident investigation procedures - Penetration Testing — Security validation and gap identification - Platform Documentation — Technology-specific implementation guides
