IT Security Management Framework and Control Integration
1. Security Governance Framework
Security Policy Foundation
The security governance framework establishes the foundation for protecting organizational assets through comprehensive policies, standards, and procedures that align with business objectives and compliance requirements. This framework ensures consistent security implementation across the organization.
Policy Components
- Information Classification and Handling
- Data classification criteria
- Handling requirements for each classification
- Data lifecycle management procedures
- Access Control Management
- Identity and access management policies
- Privileged access procedures
- Access review requirements
- Security Operations
- Incident response procedures
- Change management requirements
- Security monitoring standards
Governance Controls
Essential controls for security governance:
- Policy Management Framework
- Regular policy reviews and updates
- Policy exception management
- Compliance monitoring procedures
- Security Architecture Review
- Architecture standards compliance
- Security design principles
- Technology risk assessments
2. Access Control and Identity Management
Access Management Framework
A robust access control system protects resources while ensuring appropriate access for legitimate users. The framework incorporates multiple layers of controls and verification mechanisms.
Access Levels and Controls
- Privileged Access
Administrative access requiring enhanced controls - Elevated Access
Extended permissions with business justification - Standard Access
Regular user access based on role - Basic Access
Limited access to non-sensitive resources
Access Control Risks
Critical risks requiring mitigation:
- Unauthorized privilege escalation
- Dormant account exploitation
- Inappropriate access rights
- Authentication bypass attempts
Identity Controls
Essential identity management controls:
- Authentication mechanisms
- Multi-factor authentication
- Password complexity requirements
- Session management controls
- Access provisioning procedures
- Role-based access control
- Access request workflow
- Regular access reviews
3. Security Operations and Monitoring
Operational Security Framework
Security operations ensure continuous monitoring and protection of organizational assets through integrated tools, processes, and procedures.
Key Operational Components
- Security Monitoring
- Real-time threat detection
- Log management and analysis
- Security incident detection
- Vulnerability Management
- Regular vulnerability assessments
- Patch management procedures
- Security testing requirements
Operational Risks
Security operations risks to address:
- Delayed threat detection
- Incomplete security monitoring
- Ineffective incident response
- Unpatched vulnerabilities
Operational Controls
Critical operational security controls:
- 24/7 security monitoring
- Automated alert management
- Incident response procedures
- Regular security assessments
4. Data Protection and Privacy
Data Security Framework
Comprehensive data protection ensures confidentiality, integrity, and availability of information assets throughout their lifecycle.
Data Protection Controls
- Encryption Requirements
- Data-at-rest encryption
- Data-in-transit encryption
- Key management procedures
- Data Loss Prevention
- Content monitoring and filtering
- Data exfiltration controls
- User activity monitoring
5. Incident Response and Recovery
Incident Management Framework
Effective incident response ensures rapid detection, containment, and recovery from security incidents while minimizing impact.
Incident Response Phases
- Preparation
- Response team readiness
- Incident playbooks
- Communication procedures
- Detection and Analysis
- Incident identification
- Impact assessment
- Escalation procedures
- Containment and Eradication
- Threat containment
- Evidence preservation
- Root cause analysis
6. Compliance and Audit
Compliance Framework
Security compliance ensures alignment with regulatory requirements and industry standards while maintaining effective controls.
Compliance Requirements
- Regulatory Compliance
- Control documentation
- Compliance monitoring
- Regular assessments
- Audit Support
- Evidence collection
- Control testing
- Remediation tracking
