The ESXi host Secure Shell (SSH) daemon must use FIPS 140-2 validated cryptographic modules to protect the confidentiality of remote access sessions.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
|---|---|---|---|---|
| V-258732 | ESXI-80-000014 | SV-258732r958408_rule | High |
| Description |
|---|
| Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. OpenSSH on the ESXi host ships with a FIPS 140-2 validated cryptographic module and it is enabled by default. For backward compatibility reasons, this can be disabled so this setting must be audited and corrected if necessary. |
