Study Notes
Detecting, Responding to, and Recovering from Security Incidents
- Even with cloud security measures in place, security incidents can still occur, and it's essential to detect and respond to them quickly.
- Minor security incidents are a common part of life in some organizations and industries.
- Attackers will attempt to gain unauthorized access to assets, and it's crucial to detect them quickly, kick them out, and perform damage control.
- Understanding what attackers do and how attacks proceed is vital in detecting and responding to security incidents.
MITRE ATT&CK and Kill Chains
- Resources like MITRE ATT&CK and kill chains (e.g., Lockheed Martin Cyber Kill Chain, Unified Kill Chain) describe the tactics, techniques, and procedures (TTPs) used by attackers.
- MITRE ATT&CK is a detailed framework that shows different TTPs used in various phases of an attack and computing environments.
- Kill chains are more general outlines, listing common steps in the order attackers typically take them, such as:
- Reconnaissance
- Weaponization
- Delivery
- Exploitation
- Installation
- Command and control
- Action on objectives
- It's recommended that incident response teams read and understand at least one kill chain model and some TTPs in the MITRE ATT&CK cloud matrix.
- Understanding attacker TTPs can help when responding to an active attack.
Importance of Quick Detection and Response
- The mean time to identify a breach is 277 days, according to a study of over 550 organizations.
- Companies that identify a breach in fewer than 200 days can save over $1 million compared to those that take more than 200 days.
- Quick detection and response can significantly reduce the impact of a security incident.
