ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

A development team stores user API secrets in Amazon DynamoDB as fixed-length digests so the plaintext values are never written to disk. Today they hash each secret once with SHA-256, but a security review points out the design is still vulnerable to rainbow-table attacks if the table is leaked. Which change will MOST effectively mitigate this specific risk while keeping the stored digest roughly the same 256-bit size?

  • Concatenate a cryptographically secure random value to each secret and then hash the combined value with SHA-256 before storing it

  • Encrypt each secret with an AWS KMS symmetric customer managed key before writing it to DynamoDB

  • Hash every secret twice-first with SHA-1 and then with SHA-256-before storing the final digest

  • Compress each secret with gzip and hash the compressed output using SHA-256
