How do I deny downloading or uploading email attachments from webmail services, such as gmail or hotmail?
In order to block uploading and/or downloading of webmail attachments, use a combined object with Request URL Category(Email) and Request URL Operation (Down/Upload attachement). URL Operation policy is available in SGOS 6.2 and above.
1. From VPM, open a Web Access Layer and add a rule.
2. From the Combined Destination Object, create a Request URL Category.
3. From the same Combined Destination Object, add a new Request Web Operation Control.
4. Add the two objects with AND operation.
5. Set action to Deny.
6. Install the policy.
NOTE: Webmail services use SSL(HTTPS) for the email service. Hense, SSL interception will be required to apply this policy.
If you find any other webmail service that this policy doesn't work, please review 000008166
