Configuring Web Reputation Filtering
Web Reputation Filtering prevents client devices from accessing dangerous
websites containing viruses, spyware, malware, or phishing links. Web Reputation
Filtering detects the web threats based on the reputation score of a web page.
Reputation scores range from -10 (bad) to +10 (good). Web pages with reputation
scores below a specific threshold are considered threats and blocked.
Web Reputation Filtering only monitors and controls the website visits through the
specified HTTP port. Go to the Security Ser vices > Web URL Filtering > Advanced
Settings page to view or specify the HTTP port. See Configuring Advanc ed Web
URL Filtering Settings, page 330.
