1.3.11 Protecting and preserving forensic artifacts (for example, by using S3 Object Lock, isolated forensic accounts, S3 Lifecycle, and S3 replication)

1.3.11 Protecting and preserving forensic artifacts for example, by using S3 Object Lock, isolated forensic accounts, S3 Lifecycle, and S3 replication - In this episode, we dive deep into the essential skill of protecting and preserving forensic artifacts in AWS, a crucial competency for security engineers preparing for the AWS Certified Security - Specialty SCS-C02 exam. The discussion highlights how Amazon S3 Object Lock, isolated forensic accounts, S3 Lifecycle policies, and S3 replication work together to ensure the integrity, confidentiality, and availability of key evidence like EBS snapshots and log files. We explore the importance of maintaining a verifiable chain of custody and complying with regulatory standards such as PCI DSS, GDPR, and HIPAA, alongside strategies for advanced access control and encryption using IAM and AWS KMS. Youll hear practical examples showing how engineers can automate security workflows with AWS Lambda and EventBridge, set up monitoring and auditing using CloudTrail and server access logging, and securely recover artifacts for investigation without jeopardizing integrity. We also discuss the major challenges engineers face, from cost control and retention policy conflicts to the complexities of access and timely artifact retrieval. By mastering these AWS tools and best practices, engineers are empowered to secure digital evidence for incident response, audits, and legal proceedingsensuring forensic artifacts are preserved, protected, and ready for when theyre needed most in any cloud security investigation.
