Israeli security specialist Finjan Software has launched a brace of new products that claim to offer protection against rogue Java applets and ActiveX controls. SurfinShield and SurfinShield Xtra are designed to monitor the activity of these small applications as they are pushed onto a client's machine from the Web, in most cases without the user being aware of the download.
Most of the time, these applets or controls are harmless applications such as clocks and stock tickers that provide interactivity and functionality to Web pages. However, it's possible for a hacker to use this push behaviour to carry out attacks which can go unnoticed in the background. Unlike a virus, which advertises its presence by deleting files or interrupting your work, a Java applet could be used to download sensitive files and send them to an email address. SurfinShield products monitor the behaviour of all applets that are downloaded and sound an alarm if suspicious behaviour is detected. According to Finjan, they're extremely configurable and rely on a number of different methods to identify harmful applets, including a database of known applets, behavioural pattern-matching and the monitoring of standard system functions.
The products meant for businesses are SurfinCheck and SurfinGate, which work at the firewall level and monitor all incoming applets before they get into the network. SurfinCheck monitors just the applets' headers, a method that can detect between 70 and 80 per cent of hostile applets. SurfinGate performs a more thorough scan of the applets' code, and both products are centrally configurable.
SurfinShield 2.0 costs #70, while SurfinShield Xtra retails at #100.
A 10-user licence for SurfinGate 1.0 costs #830. A 100-seat solution and an unlimited solution are also available for #5,300 and #12,630 respectively.
