Web reputation

Web Reputation is an Internet security tool that assigns a measure of trustworthiness or safety to a Web site before a user accesses it. Designed to protect users from a growing range of Web-based threats, Web Reputation blocks access to Web sites that may distribute malicious or harmful content or files by alerting users before they can access a potentially dangerous site and become infected. The trustworthiness, or reputation, of a Web site is determined by applying a number of technologies that analyze various content and characteristics of a Web site to determine its relative safety. The following are some of the technologies that May Be used to determine a Web site’s reputation:

• Domain security profiling evaluates Web sites to gauge their trustworthiness based on factors such as whether a domain is new or has frequently changed locations

• URL filtering categorizes and blacklists Web sites based on factors that would indicate malicious nature

• Spam and phishing correlation identifies email vector attacks by matching malicious websites to the spam and phishing emails that distribute them

• Malware behavior analysis monitors network traffic to identify any behavior that may indicate malware activity

• Web site content scanning/analysis employs Web crawlers and scanning to complement the above listed techniques with a blacklist of known bad or infected sites
