McAfee SpamKiller makes 'intelligent' decisions about email with Bayesian filtering

  • 14 April, 2004 13:40

<p>Sydney, 14 April 2004 - Network Associates has announced that it has incorporated powerful new Bayesian filtering into the latest McAfee SpamAssassin engine. With the new Bayesian filtering functionality, McAfee SpamKiller for Mail Servers and McAfee SpamKiller appliances will have the ability to make ‘intelligent’ decisions about the email messages customers receive, helping to eliminate the unwanted problem of spam.</p>
<p>Bayesian filtering is based on statistical methods that give a probability for an email belonging to a given class, such as ‘spam’ and ‘not-spam.’ Bayesian auto-learning functionality automatically learns from a company's spam and non-spam email, improving the detection rates over time. This enables McAfee SpamKiller to automatically tailor itself to each company's need, as spam to one company can often be deemed important email to another. In addition, Bayesian filtering offers increased performance to McAfee SpamKiller. The McAfee SpamAssassin engine now enables McAfee SpamKiller to process three to four times more email than the latest open source version of the McAfee SpamAssassin engine and adds an additional layer of spam-detection across the whole McAfee SpamKiller product family.</p>
<p>"As spammers become more advanced in their methods of sending unsolicited email, it will become increasingly difficult to detect the difference between legitimate and illegitimate email," said Allan Bell, Asia Pacific Marketing Director for Network Associates. "With the auto-learning Bayesian system incorporated into the McAfee SpamAssassin engine, McAfee SpamKiller will be able to maintain its high capture rates despite changes in spammer tactics. This will help our corporate users reduce their potential legal liability, reclaim their network bandwidth and allow employees to work more efficiently."</p>
<p>The McAfee Bayesian filter is fully automated in its learning abilities, whereas other competitive solutions require manual training by users or systems administrators so that the filter knows what should be marked as spam. With Bayesian filtering, McAfee SpamKiller has an added layer of detection, incorporating pre-built rules-based technology that works in conjunction with ‘intelligent’ Bayesian filtering.</p>
<p>By utilising six different methods of detection, McAfee SpamKiller gives IT administrators a proactive and comprehensive solution to fighting spam:
• Bayesian filtering - the McAfee SpamAssassin engine Bayesian filtering comes pre-configured with an out-of-the-box filtering database, and features an innovative auto-learning system which will adapt to the users' particular email stream
• Integrity analysis - examines the header, layout and organization of every incoming email message and applies thousands of algorithms to determine if the email is spam
• Heuristic detection - with a set of automated rules based on known spam characteristics, McAfee SpamKiller works proactively to secure the network against spam
• Content filtering - the administrator-defined set of words and phrases helps further identify unwanted email and inappropriate content
• Personalised black and white lists - a set of standards defined by the administrator and users utilising white and black lists to determine both acceptable senders of email, as well as unwanted and unacceptable senders of email
• Self-tuning - with the ability to learn the characteristics of email received at the desktop, McAfee SpamKiller powered by McAfee SpamAssassin is able to adjust the overall spam score for messages received from known senders. This functionality is provided in McAfee SpamKiller for Mail Servers
• DNS-Blocklist support - the McAfee SpamKiller appliances are able to integrate with Internet-based DNS blocklists to ensure that email sent by known ‘spammers’ is automatically blocked.</p>
