As a security best practice, you can disable SSH access for the admin user account. The vRealize Operations Manager admin account and the Linux admin account share the same password. Disabling SSH access to the admin user enforces defense in depth by ensuring all users of SSH first login to a lesser privileged service account with a password that differs from the vRealize Operations Manager admin account and then switch user to a higher privilege such as the admin or root.
