Discussion

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.

Check Content

1. Log in to the Edge SWG SSH CLI.
2. Enter "show configuration".
3. Move down the configuration to the "security password-policy" section.

If the configuration "security password-policy min-changes" is not set to "8", this is a finding.

Fix Text

1. Log in to the Edge SWG SSH CLI.
2. Enter "enable" and "configure terminal".
3. Enter "security password-policy min-changes 8".
4. Enter "security password-policy min-groups 4".
