Web Reputation Services (WRS) scrutinizes
URLs before users access potentially dangerous websites, especially sites known to
be phishing or
pharming sites. Employing WRS,
Deep 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),
Deep Edge
does not use a locally-stored, URL database.
Web Reputation technology also assigns reputation scores to URLs. For each accessed
URL,
Deep 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. With Trend Micro Web Reputation technology
(part of
the Smart Protection Network), Deep Edge can
perform website scanning at varying protection levels (low, medium, and high).
Deep Edge provides anti-phishing and anti-pharming protection through Web Reputation, if it
is
enabled.
WRS profiles can be applied to any policy. It is safe to disable any WRS profile not
in
used.
The web reputation database resides on a remote server. When a user attempts to access
a URL,
Deep 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 Deep Edge and improves
performance.
The web reputation database is updated with the latest security information about
web pages. If
the reputation of a URL seems misclassified or to discover the reputation of a URL,
