CCI(s)

• CCI-000366 - Implement the security configuration settings.
• CCI-000370 - Manage configuration settings for organization-defined system components using organization-defined automated mechanisms.
• CCI-003627 - Disable accounts when the accounts have expired.
• CCI-003628 - Disable accounts when the accounts are no longer associated to a user.
• CCI-003831 - Alert organization-defined personnel or roles upon detection of unauthorized access, modification, or deletion of audit information.
• CCI-004046 - Implement multi-factor authentication for local; network; and/or remote access to privileged accounts; and/or non-privileged accounts such that one of the factors is provided by a device separate from the system gaining access.
• CCI-004047 - Implement multi-factor authentication for local; network; and/or remote access to privileged accounts; and/or non-privileged accounts such that the device meets organization-defined strength of mechanism requirements.
• CCI-004058 - For password-based authentication, maintain a list of commonly used, expected, or compromised passwords on an organization-defined frequency.
• CCI-004059 - For password-based authentication, update the list of passwords on an organization-defined frequency.
• CCI-004060 - For password-based authentication, update the list of passwords when organizational passwords are suspected to have been compromised directly or indirectly.
• CCI-004061 - For password-based authentication, verify when users create or update passwords, that the passwords are not found on the list of commonly-used, expected, or compromised passwords in IA-5 (1) (a).
• CCI-004063 - For password-based authentication, require immediate selection of a new password upon account recovery.
• CCI-004064 - For password-based authentication, allow user selection of long passwords and passphrases, including spaces and all printable characters.
• CCI-004065 - For password-based authentication, employ automated tools to assist the user in selecting strong password authenticators.
• CCI-004068 - For public key-based authentication, implement a local cache of revocation data to support path discovery and validation.

Fix Recommendation

Configure the network device to use an authentication server.
set system radius-server <RADIUS-1 address> secret "<PSK>"
set system tacplus-server <TACPLUS-1 address> secret "<PSK>"

Configure the authentication order to use the authentication server as primary source for authentication.
set system authentication-order radius
set system authentication-order tacplus
set system authentication-order password

Check Contents

Review the network device configuration to verify the device is configured to use an authentication server as the primary source for authentication. Verify the RADIUS and/or TACACS+ server addresses.

[edit system]
radius-server {
<RADIUS-1 address> secret "hashed PSK"; ## SECRET-DATA
<RADIUS-2 address> secret "hashed PSK"; ## SECRET-DATA
}
tacplus-server {
<TACPLUS-1 address> secret "hashed PSK"; ## SECRET-DATA
<TACPLUS-2 address> secret "hashed PSK"; ## SECRET-DATA
}

Verify the authentication order places the external authentication server first.
[edit system]
authentication-order [ radius tacplus password ];

Note: Only the global authentication order is required; all administrative access methods will honor the global setting unless configured separately.

If the network device is not configured to use an authentication server to authenticate users prior to granting administrative access, this is a finding.
