Description
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password. The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.

ℹ️ Check
Review the Arista device configuration "show management security" to determine the minimum 15-character password length. switch#show run \| section management security management security password minimum length 15 ! If the Arista network device does not enforce a minimum 15-character password length, this is a finding.

✔️ Fix
Configure the Arista device to enforce a minimum password 15-character length. switch#configure switch(config)#management security switch(config-mgmt-security)#password minimum length 15 switch(config-mgmt-security)#exit switch(config)# !
