Severity: 3-Major


When Learning is enabled in either manual or automatic mode, and is then disabled. This was considered to be the end of the learning process, and so changes are automatically made to the default wildcard entities ("*" URL, Parameter, Filetype) such as removing the element from staging. The user is not notified of these changes, and they may not be expected, leading to undesired security enforcement.


Unexpected changes to the default wildcard elements in the policy can lead to undesired security enforcement.


-- Learning is enabled in Manual or Automatic mode. -- Learning is then disabled.


The audit log shows all changes that were made to the policy, and undesired changes can be remedied before the policy changes are applied.

Fix Information

No changes are made to the default wildcard entities upon disabling of learning.
