Discussion

Centralized management of authentication settings increases the security of remote and nonlocal access methods. This control is particularly important protection against the insider threat. With robust centralized management, audit records for administrator account access to the organization's network devices can be more readily analyzed for trends and anomalies. The alternative method of defining administrator accounts on each device exposes the device configuration to remote access authentication attacks and system administrators with multiple authenticators for each network device.

Determine if the system is configured to use a primary and secondary authentication server with the following command:

cli% showauthparam
ldap-type      MSAD
accounts-dn          <accounts dn configuration>
super-map              <super-map configuration>
edit-map                  <edit-map configuration>
browse-map           <browse-map configuration>
service-map           <service-map configuration>
ldap-StartTLS        require
kerberos-realm       <Kerberos-realm configuration>
ldap-2FA-cert-field  subjectAlt:rfc822Name
ldap-2FA-object-attr mail
ldap-server          <server hostname>
ldap-server          <server hostname>
ldap-ssl-cacert:
-----BEGIN CERTIFICATE-----

If the command output does not list authparams for ldap-type, kerberos-realm, accounts-dn, ldap-ssl-cacert, and at least one role map (e.g., super-map), this is a finding. 

If there are not two ldap-server lines, this is a finding.

ldap-StartTLS must be set to require, if not, this is a finding.

If the ldap-reqcert authparam is not set to "1", this is a finding.
