Information
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.
Solution
Configure the Arista network device to use an authentication server.
Step 1: Configure the Arista network device to use RADIUS server using the following commands:
switch#config
switch(config)#radius-server host 192.168.10.101 key 7 106D1A182224E12AZ
aaa group server radius RADIUS_1
server 192.168.10.101
Step 2: Configure all network connections associated with device management to use an authentication server for login authentication.
switch(config)#aaa authentication login default group radius local
aaa authentication login console group radius local
aaa authentication dot1x default group radius
aaa authentication policy on-success log
aaa authentication policy on-failure log
aaa authorization console
aaa authorization commands all default local
aaa accounting exec default start-stop group radius logging
aaa accounting system default start-stop group radius logging
aaa accounting commands all default start-stop logging group radius
switch(config)#exit
