Fix Recommendation

Configure the ProxySG to generate alerts for access attempts to unauthorized websites and/or services.

Email may be used to send alerts directly to the ISSO/ISSM. However, use caution and be selective when choosing which Web Access rules on which to enable email notification.

1. Log on to the Web Management Console.
2. Browse to "Configuration" and click "Access Logging". Check the "Enable Access Logging" option and click "Apply".
3. Click Policy >> Visual Policy Manager >> Launch.
4. For each Web Access Layer, right-click the "Track" column for each rule and select "Set". Click "New" and select "Email".
5. Select "Custom Recipients" and click "Configure Custom Recipients Lists".
6. Click "New," provide a name for the list, and enter the ISSO and ISSM email addresses in the "List Members" field.
7. Click "OK" and click "OK" again. Create message text and click "OK".
8. Click "OK" and click "OK" again. Select File >> Install Policy on SG Appliance.
