Description

Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. OpenSSH on the Photon operating system is compiled with a FIPS-validated cryptographic module. The "FipsMode" setting controls whether this module is initialized and used in FIPS 140-2 mode. Satisfies: SRG-OS-000033-GPOS-00014, SRG-OS-000250-GPOS-00093, SRG-OS-000393-GPOS-00173, SRG-OS-000396-GPOS-00176, SRG-OS-000423-GPOS-00187
