Incident response in the cloud requires fast action because attackers can modify cloud resources quickly. Cloud providers offer tools that help teams detect respond to and recover from attacks.

Key Concepts:

• Detection: Detection uses cloud monitoring tools to identify suspicious activity such as unusual login attempts or unexpected network traffic. These tools review logs and alert security teams when something appears abnormal.
• Containment: Containment stops the threat from spreading. This can involve disabling a compromised account isolating a virtual machine or tightening security group rules. Quick containment prevents further damage.
• Investigation: Investigation uses logs snapshots and historical data to understand how the incident happened. Cloud platforms record most user and system actions which helps analysts reconstruct the attacker’s steps.
• Recovery: Recovery restores systems and strengthens them to prevent the same type of attack in the future. This may include rotating keys rebuilding systems or updating security settings.
