Incident Response Fundamentals

🚨 What is Incident Response?

Incident Response (IR) is the organized approach to addressing and managing the aftermath of a security breach or cyberattack, with the goal of handling the situation in a way that limits damage and reduces recovery time and costs.

📊 Incident Response Statistics (2024)

Average breach detection time: 287 days
Average containment time: 80 days
Cost reduction with IR team: 54% lower breach costs
Organizations with IR plan: 77% have formal plans
Incident response testing: Only 32% test regularly
Mean time to respond: 16 hours for critical incidents

🎯 Incident Categories

Security Incident Types:
  Network Attacks:
    - Denial of Service (DoS/DDoS)
    - Network intrusions
    - Man-in-the-middle attacks
    - DNS poisoning
    - Network scanning

  Malware Incidents:
    - Ransomware attacks
    - Trojan infections
    - Worm propagation
    - Rootkit installations
    - Advanced persistent threats

  Data Breaches:
    - Unauthorized data access
