Outbound Filtering Categories

The Email Security product flags messages that have suspicious content, and sorts them into one of the following categories.

Standard Categories

•

Virus: The Email Security product uses traditional signature-based filtering for virus detection. Each email message is analyzed by two separate third-party virus definitions: ClamAV and Kaspersky. By default, the system blocks all emails that have viruses detected in them.

•

Phishing: Phishing fraudulently tries to lure the user into giving up personal information such as credit card numbers, passwords, social security numbers, and account information. Phishing messages often claim to come from banks, department stores, and online merchants such as eBay. By default, the system places this type of email in quarantine.

•

Adult Spam: The Adult Spam category is reserved for spam messages exhibiting sexually explicit characteristics (words, images, hyperlinks, etc.). By default, the system blocks adult content so that it is not available within user quarantine.

•

Spam: Spam is unsolicited or unwanted bulk electronic messaging. By default, the system places this type of email in quarantine.

•

Spam Trigger: Stops "tip of the spear" spam campaigns. By default, the system places this type of email in quarantine. You can change the handling to Markup and then provide a phrase such as [TRIPWIRE] to be prepended to the email subject.

•

PDF contains Javascript: Portable document format (PDF) files can optionally contain and execute Javascript code. If a PDF file that contains Javascript is attached to an incoming message, by default the system allows these messages.

•

MS Office file contains macro: Files created with Microsoft Office applications can optionally contain and execute a macro, which is a series of commands and instructions. If a Microsoft Office file that contains a macro is attached to an incoming message, by default the system allows these messages.

•

Not AV Scanned For messages that cannot be scanned with the Email Security antivirus scanner or filtered, you can specify how the messages will be handled.

Compliance Categories: GoSecure Email Data Compliance (a separate license) filters on five additional categories. The Compliance license includes built-in health and finance lexicons that prevent accidental or malicious exposure of health and financial information – a critical factor in complying with regulatory requirements. For details about Compliance filtering, see the Data Loss Protection (DLP) section of Overview of Services

•

Social Security: Scans the message and text attachments for Social Security numbers.

•

Credit Card: Scans the message and text attachments for credit card numbers.

•

Health: Scans messages and text attachments using the Health lexicon.

•

Finance:Scans messages and text attachments using the Finance lexicon.

•

Profanity: Screens outgoing email for profanity to prevent harassment. You can also specify exceptions, if required.

Other Options

•

Attachments: For each type of attachment, you can specify how the message will be handled.

•

Content Filters: Keyword filtering of messages containing specific words, phrases, and regular expressions in the subject line, message body and plain text attachments. Other types of attachments are not filtered. Messages containing blank headers can also be filtered. Content filtering is primarily used as a security measure to prevent data leaks in outgoing mail. Administrators create one or more content filters in an account, then activate filters on individual domains and outgoing IPs as needed.
