1.1.5 Implementing credential invalidation and rotation strategies in response to compromises for example, by using AWS Identity and Access Management IAM and AWS Secrets Manager - In this episode, we explore the critical topic of credential invalidation and rotation in response to security compromises, as outlined in the AWS Certified Security - Specialty SCS-C02 Exam Guide. We explain how, when credentials like IAM access keys or secrets are compromised, its essential to quickly invalidate and replace themusing services such as AWS Identity and Access Management IAM and AWS Secrets Manager. Detection tools like GuardDuty and CloudTrail play a key role in spotting suspicious activity, after which immediate steps must be taken to deactivate affected credentials and rotate in new ones. Automation using Lambda, EventBridge, and Systems Manager can streamline these response workflows, minimizing downtime and reducing manual errors. We also cover best practices such as enforcing the principle of least privilege, enabling MFA, and regularly rotating secrets to prevent long-term exposure. Tune in to learn how mastering these skills not only boosts your AWS security posture but also prepares you for success on the AWS Certified Security - Specialty exam.
