1. Initial Assessment (0-1 hour):
   [ ] Confirm the alert details and severity
   [ ] Identify the affected cloud resources and data sets
   [ ] Establish an incident response team and communications channel

2. Containment (1-3 hours):
   [ ] Isolate affected cloud instances or containers
   [ ] Revoke potentially compromised access keys and credentials
   [ ] Enable enhanced logging and monitoring for affected resources
   [ ] Implement additional egress filtering rules

3. Investigation (3-24 hours):
   [ ] Analyze cloud trail logs and flow logs for suspicious activities
   [ ] Examine identity and access management (IAM) logs for unauthorized access
   [ ] Use cloud-native forensic tools to capture volatile data from instances
   [ ] Conduct a detailed review of data access patterns and volume

4. Eradication (24-48 hours):
   [ ] Remove any identified malware or unauthorized applications
   [ ] Close any discovered vulnerabilities or misconfigurations
   [ ] Rotate all credentials for affected systems and services
   [ ] Implement additional security controls to prevent similar incidents

5. Recovery (48-72 hours):
   [ ] Restore affected systems from clean backups if necessary
   [ ] Gradually reintroduce isolated resources back into the environment
   [ ] Implement enhanced monitoring and alerting rules
   [ ] Conduct thorough testing to ensure systems are functioning correctly

6. Lessons Learned (Post 72 hours):
   [ ] Conduct a detailed post-mortem analysis
   [ ] Update cloud security policies and procedures based on findings
   [ ] Enhance employee training on cloud security best practices
   [ ] Implement any necessary long-term security improvements

Throughout the process:
