| Description |
| 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. |

| Review the OS10 switch configuration to verify the device is configured to use at least two authentication servers as primary source for authentication. Verify that multiple radius servers are configured and that AAA login authentication is configured to use remote authentication.

| Fix Text (F-74577r1052343_fix) |
| Configure the network device to use at least two authentication servers. The authentication order is determined by the order in which the radius-server entries are configured. OS10(config)# OS10(config)# radius-server host 10.120.60.23 tls security-profile PROFILE1 key ****************** OS10(config)# radius-server host 10.120.80.82 tls security-profile PROFILE1 key ****************** OS10(config)# OS10(config)# aaa authentication login default group radius local OS10(config)# aaa authentication login console group radius local OS10(config)# Configure all network connections associated with a device management to use the authentication servers for the purpose of login authentication. OS10(config)# aaa authentication login default group radius local Optionally, configure the local console access to try local authentication before attempting remote authentication servers.
