There must be no shosts.equiv files on the RHEL 8 operating system.


Overview

Finding ID Version Rule ID IA Controls Severity
V-230283 RHEL-08-010460 SV-230283r627750_rule High
Description
The "shosts.equiv" files are used to configure host-based authentication for the system via SSH. Host-based authentication is not sufficient for preventing unauthorized access to the system, as it does not require interactive identification and authentication of a connection request, or for the use of two-factor authentication.
