Web Reputation Services (WRS) scrutinizes
URLs before users access potentially dangerous websites, especially sites known to
be phishing or
pharming sites. Employing WRS, Cloud Edge provides real-time
protection, conserves system scanning resources, and saves network bandwidth by preventing
the
infection chain or breaking it early. Web Reputation technology guards end-users against
emerging
web threats. Because a Web Reputation query returns URL category information (used
by URL
filtering), Cloud Edge does not use a locally-stored, URL
database.
Web Reputation technology assigns reputation scores to URLs. For each
accessed URL, Cloud Edge queries Web Reputation for a
reputation score and then takes the necessary action, based on whether this score
is below or
above the user-specified sensitivity level.
Cloud Edge provides anti-phishing and
anti-pharming protection through Web Reputation, if it is enabled.
The web reputation database resides on a remote server. When a user attempts
to access a URL, Cloud Edge retrieves information about this
URL from the web reputation database and stores it in the local cache. Having the
web reputation
database on a remote server and building the local cache with this database information
reduces
the overhead on Cloud Edge and improves performance.
