ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

Your company needs to automate nightly transfers of payroll files that contain PII from an on-premises Linux server to Amazon S3. The security team requires encryption in transit, mutual authentication, and the smallest possible number of inbound firewall openings. Which solution best meets these requirements while aligning with AWS best practices?

  • Establish an AWS Site-to-Site VPN and continue using plain FTP on port 21 through the tunnel.

  • Generate presigned Amazon S3 URLs and have the on-premises server upload the files over HTTPS.

  • Enable FTPS on an AWS Transfer Family endpoint and use X.509 certificates for client authentication.

  • Create an AWS Transfer Family server that uses the SFTP protocol and authenticate the on-premises host with SSH key pairs, allowing only TCP port 22 through the firewall.
