					Kaspersky Safe Surf
Today, surfing the Internet without adequate software protection is one of the most
dangerous activities a computer user can indulge in. Increasingly, users are
encountering fraud, malicious programs, botnets and spyware when browsing the web.

Surfing the net without protection affects individual users and companies, as well as
other social groups. The scale of the inflicted damage grows as more people begin to
use the Internet to bank and shop online.

A user can enhance their online security by using systems which restrict access to
malicious or undesirable websites. Kaspersky Safe Surf has been developed for just
such a purpose and is an integral feature of Kaspersky Internet Security 2011.

With Kaspersky Safe Surf the user can browse the web safe in the knowledge that they
are fully protected and will be notified of any threat situation they may come across. A
connection to a malicious or phishing site will be terminated before any dangerous code
or content is downloaded to the user’s computer, so an infection or criminal attacks will
be avoided. However, a user can still connect to a specific website if they consider that
it is safe to do so.


Site reputation

Kaspersky Safe Surf is designed to control and provide access to websites according to
an assigned security rating. Safe Surf classifies each web resource according to three
categories: Safe, Dangerous and Unknown, this last category being the case when
there is insufficient data available upon which to base a classification. Whenever the
user is about to visit an untrusted site with a low reputation which is deemed dangerous
or unclassified, their access will be restricted.

Kaspersky Safe Surf warns the user about a dangerous URL before following the link to
that address. Subsequently it may block any connection to it. The product receives site
reputation data from two sources: a Kaspersky Internet Security database of malicious
and phishing URLs located on the local system, and Kaspersky Lab’s external
centralized reputation service which is contacted online via the Internet.

Kaspersky Lab’s centralized reputation service categorizes URLs based on data about
their reputation, stores that information, and then sends the URL rating to the Safe Surf
tool on the user’s computer. When it generates a URL rating, the service performs a
comprehensive analysis, taking into account the site’s metadata, its content and known
facts about any infection. This analysis is based on advanced technologies and uses
the global database which is much more comprehensive and up-to-date than the local
database on the user’s computer.

Thus, Kaspersky Safe Surf implements an effective operational structure which expands
the capabilities of the locally installed security product. By contacting the global URL
database via the Internet, Safe Surf can react to threats in a more prompt and accurate
way. The information about new and dangerous URLs is updated faster than the
antivirus databases. The accuracy of detecting malicious and phishing sites is increased
and the number of false positive and false negative detections is reduced.
How to use Safe Surf

The Safe Surf tool integrated into Kaspersky Internet Security 2011 can check URLs
and prevent any connection to dangerous addresses. Importantly, Safe Surf only
restricts immediate access to dangerous URLs, but leaves the final decision to the user,
thus respecting both the user’s and site owner’s rights.

Kasperksy Safe Surf can check URLs listed on a webpage, such as those provided by a
search engine, and color-code them according to their security rating. Links leading to
dangerous URLs are shown in red, links to unclassified URLs are shown in blue and
safe links are not highlighted at all.

The user can enable the blocking of dangerous URLs. In this case, Safe Surf will return
a page saying that the requested URL is dangerous. Whenever an attempt is made to
access such an address, the user is prompted with the following two options: return to
the previous page or override the program and open the dangerous URL. If the user
attempts to access a website with an unclassified security rating, the user is given an
additional option to open it in the Sandbox. Once the user decides a specific URL is
safe, they can add it to the exceptions list.




Using Safe Surf’s flexible settings the user can enable or disable the checking of URLs
before they are opened and can also choose to block access to any known malicious
websites.
Kaspersky Safe Surf highlights suspicious and dangerous links in all recent releases of
Microsoft Internet Explorer and Mozilla Firefox. Connections to dangerous URLs are
blocked in each browser.

In Kaspersky Internet Security 2011, the blocking of dangerous URLs is disabled by
default.



Conclusion

These days, the Internet is a very dangerous environment for an unprotected user.
Within minutes of starting to browse the user can encounter a malicious program or a
phishing attack and face the risk of losing their money and damaging their reputation.
Kaspersky Safe Surf is similar to a traffic light network, directing the user to safe
sections of the World Wide Web and warning them when the going gets dangerous.
