Study Notes
Security Controls Types
- Preventive: Stop threats before they occur (e.g., Firewalls, MFA)
- Detective: Identify threats in progress (e.g., IDS/IPS, SIEM)
- Reactive: Address threats post-incident (e.g., Incident Response, Patching)
- Corrective: Actively reduce impact (e.g., Backup Restoration)
- Recovery: Restore asset post-impact (e.g., Disaster Recovery Plans)
CIS Controls Safeguards Implementation Groups
- Inventory and Control of Hardware/Software Assets
- Continuous Vulnerability Management
- Secure Configuration
Risk Monitoring and Audit
- Network Activity Logs: Maintain situational awareness
- Threat Trends: Monitor evolving threat landscape
- Attack Surface & Vulnerability Posture: Identify and prioritize vulnerabilities
Challenges in Security Risk Management
- Valuation of Assets: Accurately valuing data, software, and intangibles
- Likelihood of Impact/Harm: Relevance of past data for future probabilities
- Unpredictable nature of future attacks
- Resulting Risk Assessment: Accuracy of assessment with uncertain data
- Subjectivity in Risk Treatment: Which risks to treat or accept?
ISO 27002 Standard
- Provides a comprehensive set of best practices for information security controls
- 14 Security Control Clauses:
- Information Security Policies
- Organization of Information Security
- Human Resource Security
- Asset Management
- Access Control
- Cryptography
- Physical and Environmental Security
- Operations Security
- Communications Security
- System Acquisition, Development, and Maintenance
- Supplier Relationships
- Information Security Incident Management
- Information Security Aspects of Business Continuity Management
- Compliance Structure of Control Categories: Each clause contains one or more security categories
ISO 27004 Standard
- Focuses on measuring security performance and effectiveness of ISMS
- Key Aspects:
- Information security performance
- Effectiveness of ISMS processes and controls
- Monitoring, Measurement, Analysis, & Evaluation Process:
- Establish measurement constructs
- Use metrics like training statistics, incident data, and internal audits
- Example Metrics: Mean Time to Detect (MTTD), Mean Time to Resolve (MTTR), Phishing attack success rates
Challenges in Security Risk Management
- Challenge 1: Assets as Attack Platforms
- IoT devices can serve as attack platforms
- Most organizations lack full understanding of their assets
- Challenge 2: Third-Party System Risks
- Organization B may not know details of systems at Organization A or C
- These third-party systems can pose significant security risks
- Challenge 3: Assessing the Glue
- Difficulty understanding and assessing logical links between systems
- Traditional assessments focus on systems and connections but ignore the logical glue
