IBM has introduced technology to help SMEs reduce the cost and security risks associated with spam and to make existing spam filtering solutions more effective.

The technology, FairUce (Fair use of Unsolicited Commercial E-mail), analyses the domain identity of an e-mail, helping to establish each message’s legitimacy by linking it back to its origin in terms of e-mail address, domain and originating computer. Since IP addresses are fixed and cannot be changed, this enables users to identify messages sent from zombie computers, or bot devices, as well as those from legitimate servers.
Spammers who assume false identities should therefore be unable to hide, which should reduce the growing threats of phishing and spoofing.
FairUce is designed to work alongside traditional spam filters, which scan e-mail content as it enters the network, but which can heavily tax network bandwidth. Its key benefit is to allow users to identify potentially harmful traffic as early as possible before it enters the network proper.
Stuart McIrvine, director of corporate security strategy at IBM, said, “Spam has become a high-priority security issue for businesses today. By creating a multi-layered defence that proactively repels spam at its source, SMEs can get ahead of spammers and malicious hackers, who are always looking for new ways of penetrating IT systems through e-mail.”
