ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

Your security team audits an Amazon EC2-based application that reads a YAML configuration file on each instance to obtain database credentials. Finding that the file is world-readable, they ask you to redesign the solution to maximize confidentiality and comply with the principle of least privilege. Which approach best satisfies both requirements without adding unnecessary components or complexity?

  • Hard-code the credentials in the application source code and use code obfuscation to prevent disclosure.

  • Store the credentials in AWS Secrets Manager and attach an instance IAM role that is limited to the GetSecretValue action for that specific secret.

  • Keep the credentials on disk but change the file permissions to 600 so only the root user can read it.

  • Upload the credentials to a private S3 bucket and grant the entire VPC permission to download the object through a VPC endpoint.
