Which statement accurately describes SSL usage on host devices in PCI scanning?

• A. Any form of SSL on a host device is an automatic failure, with the exception for POS devices that can prove no downgrade vulnerability.
• B. SSL on host devices is always allowed if the device is PCI-compliant.
• C. POS devices are never subject to SSL restrictions.
• D. SSL usage on host devices is unrelated to PCI scope.

Answer: (A)

SSL on host devices is treated as a red flag in PCI scanning because cardholder data must be protected with strong cryptography and legacy protocols like SSL are not considered acceptable for protecting data in transit. When a host device uses SSL, it often signals the presence of weak or deprecated encryption (or a potential downgrade path), which ASV scans flag as a failure. The only exception is POS devices, which may be allowed to use SSL if they can prove there is no downgrade vulnerability—meaning they won’t expose data through weaker protocols or older TLS versions. In short, strong, up-to-date encryption is required across the environment, and SSL usage on host devices is not permitted unless a POS device can demonstrate it isn’t vulnerable to downgrades.
