ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

An application running on Amazon EC2 continuously compresses and writes gigabyte-scale log files to local storage before uploading them to encrypted Amazon S3. The security team wants confidentiality for the on-disk logs, minimal CPU overhead during writes, and simple key rotation using AWS KMS. Which approach best meets these requirements?

  • Encrypt each log file with RSA-2048 using an AWS KMS customer master key (CMK).

  • Generate a SHA-256 digest of each file and store the hash alongside the file for later verification.

  • Digitally sign each file with the Elliptic Curve Digital Signature Algorithm (ECDSA) before saving it.

  • Encrypt each log file locally with AES-256 in Galois/Counter Mode using a data key supplied by AWS KMS.
