When it comes to protecting your organization from threats, functional controls play a crucial role in ensuring security. Let’s dive into the types and categories of functional controls in a simple, easy-to-understand way that’s perfect for beginners and pros alike.

DetectiveIdentifies and alerts to suspicious activitiesIntrusion Detection Systems (IDS), Security logs, Video surveillance
CorrectiveFixes the issue after an incidentData backups, Patch management, Incident response plans
DeterrentDiscourages malicious actionsSecurity cameras, Warning signs, Publicized penalties
CompensatingProvides alternatives when primary controls aren’t enoughVPNs for secure access, Enhanced system monitoring
DirectiveEstablishes rules and provides guidanceSecurity policies, Standard Operating Procedures (SOPs), Mandatory employee training

Why These Controls Matter:

  • Preventive controls act like locked doors, stopping bad actors at the outset.
  • Detective controls are your alarm system, alerting you to trouble.
  • Corrective controls help you clean up and recover.
  • Deterrent controls make attackers think twice.
  • Compensating controls provide a safety net when primary options aren’t viable.
  • Directive controls ensure everyone knows the rules and sticks to them.

Categories of Controls
