Fix Recommendation

Obtain the list of network services that have not been authorized or approved by the ISSM and ISSO. For each prohibited network service, configure a security policy that denies traffic associated with it and logs the denied traffic.

To configure a Security Policy to log denied traffic:
Go to Policies >> Security
Select "Add" to create a new security policy or select the name of the security policy to edit it.
Configure the specific parameters of the policy by completing the required information in the fields of each tab.
In the "Actions" tab, select the Log forwarding profile and select "Log at Session End".
"Log at Session Start" may be selected under specific circumstances, but "Log at Session End" is preferred.
Commit changes by selecting "Commit" in the upper-right corner of the screen.
Select "OK" when the confirmation dialog appears.

Check Contents

Obtain the list of network services that have not been authorized or approved by the ISSM and ISSO. For each prohibited network service, view the security policies that denies traffic associated with it and logs the denied traffic.

To verify if a Security Policy logs denied traffic:
Go to Policies >> Security
Select the name of the security policy to view it.

In the "Actions" tab, in the "Log Setting" section, if neither the "Log at Session Start" nor the "Log at Session End" check boxes are checked, this is a finding.
