SNMP

A simple SNMP trap will be generated to inform the operators’ alerting system that a virus has been detected. This SNMP trap could contain the sending and receiving MSISDN, however the initial solution would reflect the current behavior, i.e. only the fact that a virus has been detected will be communicated.

MMS content-based Antispam protection

Expand MMS Scanning and select Content Filter in an MMS protection profile to create content filter black/white lists that block or allow MMS messages based on the content of the message.

Overview

A school computer lab may block age-inappropriate content. A place of business may block unproductive content. A public access internet cafe may block offensive and graphic content. Each installation has its own requirements for what content needs to be blocked, and in what language.

FortiOS Carrier provides the ability to create custom local dictionaries, black lists, and white lists in multiple languages enables you to protect your customers from malicious content around the world.

MMS content-based Antispam protection

Configurable dictionary

You can create a dictionary of configurable terms and phrases using the CLI. The text of MMS messages will be searched for these terms and phrases. Add content filter lists that contain content that you want to match in MMS messages. For every match found, a score is added. If enough matches are found to set the total score above the configured threshold, the MMS message is blocked.

You can add words, phrases, wild cards and Perl regular expressions to create content patterns that match content in MMS messages. For more on wildcard and regular expressions, see Using wildcards and Perl regular expressions in the UTM guide.

For each pattern you can select Block or Exempt.

• Block adds an antispam black list pattern. A match with a block pattern blocks a message depending on the score of the pattern and the content filter threshold.
• Exempt adds an antispam white list pattern. A match with an exempt pattern allows the message to proceed through the FortiOS Carrier unit, even if other content patterns in the same content filter list would block it.

If a pattern contains a single word, the FortiOS Carrier unit searches for the word in MMS messages. If the pattern contains a phrase, the FortiOS Carrier unit searches for all of the words in the phrase. If the pattern contains a phrase in quotation marks, the FortiOS Carrier unit searches for the whole phrase.

You can create patterns with Simplified Chinese, Traditional Chinese, Cyrillic, French, Japanese, Korean, Spanish, Thai, or Western character sets.
