Solution #00004872
Scope:
Applies to all Email Security Gateways.
Answer:
The Intent Analysis layer of the Email Security Gateway performs analysis for all domains and URLs inside of email messages to identify links pointing to spam websites.
The Email Security Gateway stores a local database of these spam patterns as part of the energize update process. The local database is updated several times per hour.
Unfortunately, spam attacks are frequently launched using new domains that have never been associated with spam. Due to this dynamic nature of spam, there is a small window of opportunity for spam to get through in between the energize updates.
Enter the Real-time Intent analysis. This analysis step on the Email Security Gateway checks a real-time server at Barracuda Central. The Real-time Intent analysis allows the identification of any new domains that have been identified in emerging spam campaigns. Real-time Intent focuses on the name servers that belong to the domains in question. It will analyze them for known spam tactics and ensure they are not malicious. This provides Barracuda Networks customers continuous coverage from the activities of spammers.
