Real
time website scanning and blocking
eScan scans websites in real time. When
words related to pornography, gambling or other subject that you specify are detected
in a website, the site is blocked and a message is displayed giving reasons for
blocking the site. Screen below shows a typical message that is displayed
when a website is blocked as it has pornographic related contents.
Block
web sites based on predefined pornographic keywords
eScan has parental
control feature that allow you to control access to web sites You can specify
words and phrases like xxx, porn, adults only, poker, etc. that occur in porn
and gambling sites. If the accessed site contains such words, it is blocked and
not allowed to display on your system. The following points are explained. Category:
Category carries related group of web sites Access to all web sites that are defined
in a category can be either blocked or allowed. For e.g. the category 'Pornography'
will have web sites related to porn. You can block or allow access to sites that
occur in this category. Categories like pornography and gambling have been created
with a block status. You can create user defined categories. The next step
is adding words related to the category. Words/Phrases: You can add
to the list of words that relate to a category. For e.g. for porn category, you
can add words like babes, xxx, etc. If the category Pornography is blocked then
eScan blocks any site that has words like babes, xxx, etc. Everyday about
500 sites related to porn are added to the Internet. To avoid detection, some
of the sites are also renamed. This feature ensures that when a site with such
words in the content, keywords, script and tags occurs, access to the site is
automatically blocked even though it has been renamed. Site Names: Some
well-known sites like playboy, hustler, etc. do not change names. You can specify
such sites and access to them is blocked outright. The feature is found
in eScan Content Administrator > Webpage Scanning > Filter Categories (Frame) The
features are marked in red in the following screen. 
Block
websites using IP Address
Websites can be accessed by entering their IP
(Internet Protocol) number. The software should be able to translate the IP number
to its web site name and block access if it contains restricted words or is on
the banned list.
For e.g. www.sex-circus.com can be accessed through its
IP, http://198.63.10.71 when you use common Content Security software. Software's
like eScan are able to translate the IP to its URL and block it.
