AOSX-12-000570
(in versions v1 r6 through v1 r1)
Title
The OS X system must implement NSA-approved cryptography to protect classified information in accordance with applicable federal laws, Executive Orders, directives, policies, regulations, and standards. (Cat II impact)
Discussion
Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. The operating system must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. Satisfies: SRG-OS-000112-GPOS-00057, SRG-OS-000113-GPOS-00058, SRG-OS-000396-GPOS-00176
Check Content
To check which protocol is configured for sshd, run the following: /usr/bin/sudo /usr/bin/grep ^Protocol /etc/ssh/sshd_config If there is no result or the result is not "Protocol 2", this is a finding.
Fix Text
To ensure that "Protocol 2" is used by sshd, run the following command: /usr/bin/sudo /usr/bin/sed -i.bak 's/.*Protocol.*/Protocol 2/' /etc/ssh/sshd_config
