Security Operations

Security Operations is weighted at 18% in the current CC outline. It tests day-to-day security work: protect data, harden systems, monitor events, follow policies, and help users make safer decisions.

Work this domain in order

1. Data Security and Logging for encryption, hashing, classification, labeling, retention, destruction, logging, and monitoring.
2. System Hardening and Configuration Management for baselines, updates, patches, and configuration discipline.
3. Policies and Awareness Training for data handling, password, AUP, BYOD, change management, privacy, social engineering, and safe user behavior.

Operations mindset

	  I["Inventory"] --> B["Baseline"]
	  B --> H["Harden"]
	  H --> M["Monitor"]
	  M --> R["Review and improve"]

Operations answers should be repeatable and provable. If nobody owns the task, reviews logs, tests recovery, or updates the baseline, the control is weak.

In this section

• Data Security and Logging
  Study ISC2 CC data security and logging: symmetric encryption, asymmetric encryption, hashing, classification, retention, destruction, and monitoring.
• System Hardening and Configuration Management
  Study ISC2 CC hardening and configuration management: baselines, updates, patches, secure settings, documentation, approval, rollback, and verification.
• Policies and Awareness Training
  Study ISC2 CC best-practice security policies and awareness training: data handling, passwords, AUP, BYOD, change management, privacy, and social engineering.
