Best Practices toSecuring Your AWS Account • Lock down the root account • Follow least privilege for IAM Users and Roles • Ensure S3 ACLs and Bucket Policies are properly configured. • Enable a strong password policy and MFA requirement for IAM users. • Enable CloudTrail and AWS Config • Leverage encryption for services that have KMS integration • Not a one time activity – Continuously monitor for changes.

- 10. Monitor Activity andIdentify Insecure Configurations Inventory the services and regions you are using. • What regions do you have VPCs in. • Which resources are accessible from the Internet. • Leverage AWS CloudTrail to identify new VPCs or service usage. • Define a consistent Tagging and Naming strategy for resources Ensure the AWS Services you’re using remain securely configured. • Disable non-secure ciphers on Elastic Load Balancing. • Remove Amazon S3 bucket permissions that allow global write or read. • Identify security groups or network ACLs that allow unrestricted access to sensitive ports.
- 11. Monitor Activity andIdentify Insecure Configurations (cont.) Identify and remediate vulnerabilities in AMIs • Patch your AMIs not your instances. • Maintain a list of trusted AMIs, restrict users from launching non-trusted images. • Scan instances frequently to identify new vulnerabilities. Scanning tools must be cloud aware • Don’t assume your instances will be running during scan windows. • Replace rather than patch ephemeral instances • Watch for inherited vulnerabilities from 3rd party plugins or open source packages
