Aladdin seals door on spam
1 April 2005 | 0
Tools and features to control e-mail-borne spam or malicious code have been added to the latest version of eSafe Gateway, Aladdin Knowledge Systems’ content filtering product.
eSafe Gateway scans all inbound e-mail and network traffic for signs of damaging, or productivity-robbing content. It deals with each of the seven major threats with a combination of analytical tools and proven techniques
According to Aladdin, the seven major e-mail borne threats to network security are: Exploits, spam, cookies, known and unknown viruses, malicious scripts, untrusted office documents, and Denial of Service (DoS) attacks.
Exploits are so called because they take advantage of security holes in operating systems. For instance, the recent Bugbear e-mail worm exploited the MIME-type vulnerability found in Outlook Express. Aladdin’s XploitStopper stops all known exploits including IFRAME/FRAME HTML Tag, ActiveX, Attached Script, Hidden File, CLSID File and many more.
Aladdin has added new spam fighting technologies to eSafe and now brings to bear six highly-effective spam prevention methods: Real time black listing (RBL), DNS lookup, anti-relay, anti-spoofing, cookies blocking, and keyword filtering.
eSafe also strips cookies from e-mail. It is claimed that when used in combination with Aladdin’s layered spam prevention technologies, rates of unsolicited e-mail fall dramatically.
Aladdin deploys MacroTerminator and Ghost Machine to detect and protect against polymorphic and encrypted viruses, as well as macro virus variants.
For unknown viruses released in the wild, SmartScript blocks any malicious script it detects while smart file rules, combined with file-spoofing protection are on guard to block unknown malicious files. Organisations can prevent mail-bomb or Denial of Service attacks by monitoring the number of e-mail sessions that are open at the same time and the total number of e-mail messages in the spooler.
Traffic from each direction is monitored separately; when either the maximum number of incoming e-mail sessions, or the maximum number of e-mail files is reached, incoming connections are rejected. eSafe prevents a variety of DoS tactics including oversize file attacks and over-recursive, compressed file attacks from propagating and jamming mail servers.
