White Paper: Controlling Unwanted Content
MX Logic: Content and Attachment Filtering
In addition to Spam Blocking, which can help to provide a first layer of email content control, Content and Attachment Filtering, a component of MX Logic’s Email Defense Service, provides comprehensive filtering for unwanted content, including critical keyword filtering and attachment control.
CONTENT AND ATTACHMENT FILTERING: KEYWORD FILTERING
Content and Attachment Filtering evaluates the content of all messages based on the policies and associated actions configured by the organization. These policies can be quickly and easily configured to disallow the inbound and outbound transmission of private or proprietary corporate data, racially- and sexually-insensitive material, profanity, and other content deemed inappropriate by the enterprise.
Content and Attachment Filtering uses a “bucket” configuration to organize keywords. These buckets (“Profanity,” “Sexual Overtones,” “Racially Insensitive,” etc.) contain related keywords which, when detected, indicate that the message contains unwanted content. Each bucket can be turned on and off, depending on the organization’s policies. Additionally, Content and Attachment Filtering allows an enterprise to create its own keyword bucket, so it can filter messages for sensitive corporate information, as well as any words or phrases that the enterprise would like to use to prevent specific content from entering or leaving its network.
CONTENT AND ATTACHMENT FILTERING: ATTACHMENT CONTROL
Content and Attachment Filtering blocks unwanted attachments before they enter or exit the corporate network. Attachments are filtered according to configurations set by the enterprise IT administrator. Attachments can be filtered in a number of ways: by size, by MIME media type (.exe, .vbs, .mp3, etc.), by binary content (making sure the attachment’s content matches the indicated file type), and, if they are images, by image analysis.
