Discussion

Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Remote access (e.g., RDP) is access to DOD nonpublic information systems by an authorized user (or an information system) communicating through an external, nonorganization-controlled network. Remote access methods include, for example, dial-up, broadband, and wireless. Cryptographic mechanisms used for protecting the integrity of information include, for example, signed hash functions using asymmetric cryptography enabling distribution of the public key to verify the hash information while maintaining the confidentiality of the secret key used to generate the hash.

Check Content

Note: For AHV, this requirement is Not Applicable. 

Verify AOS, Prism Central, and Files OS VMs are configured to only use ciphers employing FIPS 140-3-approved algorithms.

1. Verify the "opensslcnf.config" is defined in the "/etc/pki/tls/openssl.cnf" file.

sudo grep -i opensslcnf.config /etc/pki/tls/openssl.cnf
.include /etc/crypto-policies/back-ends/opensslcnf.config

2. Verify the systemwide crypto policy is set to "FIPS".

$ sudo update-crypto-policies --show
FIPS

If the systemwide crypto policy is not set to "FIPS" or the "opensslcnf.config" is not defined in the "/etc/pki/tls/openssl.cnf", this is a finding.
