The NSX Manager must require that when a password is changed, the characters are changed in at least eight of the positions within the password.

Description
If the application allows the user to consecutively reuse extensive portions of passwords, this increases the chances of password compromise by increasing the window of opportunity for attempts at guessing and brute-force attacks. The number of changed characters refers to the number of changes required with respect to the total number of positions in the current password. In other words, characters may be the same within the two passwords; however, the positions of the like characters must be different. Multifactor authentication (MFA) is required for all administrative and user accounts on network devices, except for an account of last resort and (where applicable) a root account. Passwords should only be used when MFA using PKI is not available, and for the account of last resort and root account.

ℹ️ Check
From an NSX Manager shell, run the following command: > get password-complexity If the number of consecutive characters allowed for reuse is not eight or more, this is a finding. Note: If this has not previously been configured it will not be shown in the output.

✔️ Fix
From an NSX Manager shell, run the following command: > set password-complexity max-repeats 8
