Overview

This video introduces the fundamental concepts of security controls, explaining their purpose in preventing, deterring, detecting, and correcting security incidents. It categorizes controls into technical, managerial, operational, and physical types, and further breaks down control types into preventive, deterrent, detective, corrective, compensating, and directive. The video uses examples to illustrate how specific controls fit into these categories.

Key takeaways

• Purpose of Security Controls: Security controls are implemented to prevent security events, minimize their impact, and limit damage if an incident occurs.
• Categories of Security Controls:
  • Technical Controls: Implemented using technology (e.g., firewalls, antivirus, OS policies).
  • Managerial Controls: Involve policies, procedures, and documentation (e.g., security policies, onboarding procedures).
  • Operational Controls: Rely on people to execute security measures (e.g., security guards, awareness training, lunch-and-learns).
  • Physical Controls: Protect physical access to facilities, rooms, or devices (e.g., fences, locks, badge readers, guard shacks).
• Types of Security Controls:
  • Preventive: Limit access to resources (e.g., firewall rules, guard shacks).
  • Deterrent: Discourage potential attackers (e.g., splash screens, threat of demotion, warning signs).
  • Detective: Identify when a breach occurs and log information (e.g., system logs, motion detectors, patrolling guards).
  • Corrective: Occur after detection to reverse impact or minimize downtime (e.g., restoring from backups, contacting law enforcement, using a fire extinguisher).
  • Compensating: Provide alternative means to control a security event when direct controls are not feasible (e.g., temporary firewall rules, separation of duties, generators).
  • Directive: Direct individuals to perform actions securely (e.g., requiring sensitive data in encrypted folders, "authorized personnel only" signs).
• Categorization Matrix: The video demonstrates how specific control examples can fit into both a category (technical, managerial, operational, physical) and a type (preventive, deterrent, detective, corrective, compensating, directive).
