Content Control

Attachment Control

Attachment filtering can be used to control a wide range of problems originating from both inbound and outbound attachments in email messages and web requests, including the following:

ƒ Viruses and Spyware — Attachments and downloads carrying viruses, spyware, and other types of malware can be blocked.

ƒ Offensive Content — The system blocks the transfer of images, which reduces the possibility that an offensive picture will be transmitted to or from your company messaging and web systems.

ƒ Confidentiality — Prevents unauthorized documents from being transmitted through the system.

ƒ Loss of Productivity — Prevents your systems from being abused by employees.

In policies, email and web actions can be set for both inbound and outbound Attachment Control. In addition, administrators can configure separate types of Attachment Control file and MIME type lists for email and web traffic.

Attachment stripping

The Attachment Control feature provides the ability to identify and remove attachments from inbound and outbound mail messages. Administrators can configure a list of specific attachment extensions or MIME types that should be stripped from a message before it is delivered. A configurable notification text attachment will replace the attachment that was removed to indicate to the user that the attachment was stripped and specify the reason why it was removed.

Attachment Stripping is a global feature, and cannot be configured on a per-policy basis
