This article provides information on the Webwasher Content Security Management software developed by CyberGuard Corp. Hackers are scheming about how to exploit the announced vulnerability in a number of Microsoft operating systems and applications, including Office and several versions of Internet Explorer. The reported weakness allows malignant JPEG images to enter users' computers undetected via e-mail, web site and instant message downloads, enabling an attacker to gain control of the computer. Webwasher's solution has built-in provisions that defend against new threats from file types that have previously been considered harmless. Rather than spending all day updating patches and scanning for new threats just to keep up, Webwasher relies on a deeper examination of files to prevent malicious viruses and worms from infiltrating networks. Virtual LAN support allows administrators to connect network nodes physically located on different segments of a network and apply the same high degree of network security control to the 'virtual group' treating them the same as if they resided on a single physical network segment. With the availability of an optional 6-port Gigabit Ethernet network interface card, CyberGuard claims it can deliver throughputs similar to competitive products offered at more than twice the price.
