The Spyware Threat
Spyware is software that utilizes a computer’s Internet access without the host’s knowledge or
permission. Spyware can gather information about browsing habits, data entered into online forms,
and keystrokes.
Computers are infected with Spyware applications from a variety of sources:
• Downloaded programs such as P2P applications, freeware, screensavers, utilities,
download managers, demo software, and video games.
• Trojans delivered through e-mail, downloaded from an FTP site, or installed with freeware.
• Banner ads
The impact of spyware for users includes the following threats:
• Identity theft
• Stolen proprietary data
• Invasion of privacy
• Degraded computer performance
• Excessive bandwidth use resulting in a network slowdown
SonicWALL Anti-Spyware Security Service
The SonicWALL Anti-Spyware Service protects networks from intrusive spyware by cutting off
spyware installations and delivery at the gateway and denying previously installed spyware from
communicating collected information outbound. SonicWALL Anti-Spyware works with other
anti-spyware programs, such as applications that remove existing spyware applications from hosts.
You are encouraged to use or install host-based anti-spyware software as an added measure of
defense against spyware.
Benefits
SonicWALL Anti-Spyware analyzes inbound connections for the most common method of spyware
delivery, ActiveX-based component installations. It also examines inbound setup executables and
cabinet files crossing the gateway, and resets the connections that are streaming spyware setup
files to the LAN. These file packages may be freeware bundled with adware, keyloggers, or other
spyware. If spyware has been installed on a LAN workstation prior to the SonicWALL Anti-Spyware
solution install, the service will examine outbound traffic for streams originating at spyware infected
