Cisco Cisco Web Security Appliance S670 사용자 가이드

The Web Security appliance is a robust, secure, efficient device that protects 
corporate networks against web-based malware and spyware programs that can 
compromise corporate security and expose intellectual property. The Web 
Security appliance extends IronPort’s SMTP security applications to include 
protection for standard communication protocols, such as HTTP, HTTPS, and 
FTP. 

Malware (“malicious software”) is software designed to infiltrate or damage a 
computer system without the owner’s consent. It can be any kind of hostile, 
intrusive, or annoying software or program code. Web-based malware includes 
spyware, system monitors, adware, phishing and pharming techniques, keystroke 
(key) loggers, browser hijackers, trojan horses, and more.

Web-based malware is a rapidly growing threat, responsible for significant 
corporate downtime, productivity losses and major strains on IT resources. 
Additionally, companies run the risk of violating compliance and data privacy 
regulations if their networks become compromised by malware. Companies run 
the risk of expensive legal costs and exposure of intellectual property.

The best place to stop these threats from entering the network is right at the 
gateway. The Web Security appliance provides deep application content 
inspection, by offering a web proxy service and by monitoring layer 4 traffic. The 
Web Proxy and Layer 4 Traffic Monitor allow organizations to ensure breadth of 
coverage within their networks. The Web Security appliance provides a powerful 
web security platform to protect your organization against malware that is 
optimized for performance and efficacy.
