Title
The network device must be configured to use at least two authentication servers for the purpose of authenticating users prior to granting administrative access. (Cat I impact)
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.
Check Content
Review the network device configuration to verify that the device is configured to use at least two authentication servers as primary source for authentication. If the network device is not configured to use at least two authentication servers for the purpose of authenticating users prior to granting administrative access, this is a finding.
Fix Text
Step 1: Configure the network device to use at least two authentication servers. Step 2: Configure the authentication order to use the authentication servers as primary source for authentication. Step 3: Configure all network connections associated with a device management to use the authentication servers for the purpose of login authentication.
