Title

The container platform must require the change of at least 15 of the total number of characters when passwords are changed. (Cat II impact)

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.

Check Content

Review the container platform configuration to determine if it requires the change of at least 15 of the total number of characters when passwords are changed. If the container platform does not require the change of at least 15 of the total number of characters when passwords are changed, this is a finding.
