Anti-Spyware
Spyware/grayware often gets into a corporate network when users download legiti-
mate software that has grayware applications included in the installation package.
Most software programs include an End User License Agreement (EULA), which the
user has to accept before downloading. Often the EULA does include information
about the application and its intended use to collect personal data; however, users
often overlook this information or do not understand the legal jargon.
The existence of spyware and other types of grayware on your network have the
potential to introduce the following:
• Reduced computer performance
• Increased Web browser-related crashes
• Reduced user efficiency
• Degradation of network bandwidth
• Loss of personal and corporate information
• Higher risk of legal liability
To address these problems, the Anti-Spyware function in InterScan Gateway Security
Appliance helps protect LAN users from inadvertently downloading spyware and
grayware, which can collect personal and corporate information, reduce computer
performance, degrade network bandwidth, and more seriously, compromise the
security of the network.
Using the spyware scan engine, pattern file, and cleanup template, the Anti-Spyware
function in InterScan Gateway Security Appliance monitors inbound and outbound
SMTP, POP3, HTTP, and FTP traffic for spyware and grayware.
