Ransomware defense combines prevention, detection, response, and recovery controls across the full attack lifecycle to protect against encryption and data extortion.
Ransomware defense is the comprehensive set of preventive, detective, and recovery controls that protect an organization from ransomware attacks. It spans the entire attack lifecycle: preventing initial access, detecting lateral movement, containing encryption, and recovering operations.
Ransomware defense operates across the kill chain:
Prevention (before the attack):
Detection (during the attack):
Response (containing the attack):
Recovery (after the attack):
Ransomware is the most financially impactful cyber threat facing organizations. The numbers are stark:
Ransomware groups now routinely exfiltrate data before encrypting, creating dual pressure: pay to decrypt AND pay to prevent data publication.
Ransomware defense spans all six PDM domains:
CDA mission TID-D01 (Tabletop Exercise, Ransomware) tests organizational readiness. The full ransomware resilience campaign spans C-RECON (assessment) through C-COMMAND (sustained operations).

Rogue access point detection identifies unauthorized wireless APs on the network using WIPS sensors, wired-side monitoring, and signal triangulation to prevent network bypass.
LLM security risks include data leakage, prompt injection, model supply chain attacks, and unauthorized tool execution, requiring organizations to treat AI models as high-privilege components.
How physical security failures enable cyber attacks, from tailgating and shoulder surfing to device theft and dumpster diving.
