Chapter 1: K9 Web Protection Overview
Blue Coat® K9 Web Protection is a content filtering solution for your home
computer. It implements the same reliable Web filtering technology used world
wide by enterprise and government customers, providing a user-friendly
experience that allows you to control Internet use in your home.
Blue Coat's Web filtering technology divides Internet content into 69 distinct
categories. These categories—and their associated Web sites—are stored in the
Blue Coat WebFilter database, which maintains and updates millions of Web
site ratings and domains. A Web site belongs to one or more of these categories,
based on the content of the site.
To meet your particular needs and preferences, you can configure the software
to block or allow specific categories.
K9 Web Protection offers:
❐
Service-based filtering—The Blue Coat filtering service receives and rates
25-30 billion requests every day, making it the most accurate content
filtering database available and ensuring that you are protected against the
ever-growing number of inappropriate Web sites. With no database to
download, K9 Web Protection does not slow down your computer.
❐
Dynamic Real-Time Rating™ (DRTR)—Blue Coat's patent-pending DRTR
technology automatically determines the category of an unrated Web page.
Unlike other filtering solutions, K9 Web Protection guarantees the highest
level of protection by building the most relevant ratings database available.
Using statistical analysis and artificial intelligence methods to rate new or
previously unrated Web pages, DRTR only provides a rating when it is
confident that it has reached an accurate conclusion. Its effective coverage
reaches more than a billion Web pages.
❐
Efficient caching—Caching is the method your Web browser uses to save
frequently used data, which increases efficiency by reducing the amount of
information requested over the Internet.K9 Web Protection uses Blue Coat's
unique caching technology, so your Internet experience is always as fast as
possible.

Configuring Web Categories
Blue Coat maintains a database that categorizes URLs based on the nature of
their content. This database, referred to as the Blue Coat WebFilter (BCWF)
database, is what K9 Web Protection uses to classify the Web sites users access
on this computer.
By selecting Web categories to allow or block, you control the nature of the
content users can access on this computer. For example, if you allow Web sites
categorized as News/Media, users on this computer can visit Web sites like
www.cnn.com, www.foxnews.com, and so on. By blocking Web sites categorized as
Gambling, you prevent users on this computer from accessing gambling Web
sites.
This section discusses categories in the following topics:

"Selecting A Defined Category Set"
"Creating a Custom Protection Level" on page 27
Selecting A Defined Category Set
K9 Web Protection has several pre-configured sets of categories. Each set of
categories (sometimes referred to as protection levels) blocks a range of content
that is typically considered to be offensive or harmful. These category sets
range from High (maximum number of Web categories blocked) to Monitor (no
categories are blocked but all are logged).
To select a different defined protection level:
1. Start K9 Web Protection as discussed in "Logging in to K9 Web Protection"
on page 21.
2. From the top menu bar, click Setup.
3. If you have not already logged in, enter your administrator password at the

Forcing Safe Search or Blocking Unsafe Search
This section discusses how to perform the following tasks:
❐
Force safe search: Force a search engine that supports Safe Search to enable its
strictest search filter; however, the quality of the filtering is based on the
engine’s built-in capabilities. The same search string entered on one search
engine might yield different results when entered on another search engine
(including varying levels of inappropriate content).
Safe Search is supported on the following search engines:
•
•
•
•
•
•
•
A9
Altavista
MSN/Live
Google
Yahoo
Ask
Orange.co.uk
With safe search enabled, the search engine Web page typically displays Safe
Search ON, Family Filter On, Safe Search Strict, or another engine-specific
message.
❐
Block search engines that do not use safe search: Prevent the use of a search
engine that does not support safe search.
If a user on your computer attempts to use a search engine that does not
support safe search (for example, www.webcrawler.com), the following page
displays:
29
K9 Web Protection User Manual
Note: For maximum control over searching, Blue Coat recommends you
enable both options. If you enable safe search but disable block unsafe search,
users can get search results from unsupported search engines. For example, if a
user goes to www.webcrawler.com and searches for offensive content,
Webcrawler returns URLs that are consistent with the search. However, users
cannot visit offensive Web pages if you set up categories or other policies to
block access to the content.
To set search engine options:
1. Start K9 Web Protection as discussed in "Logging in to K9 Web Protection"
on page 21.
2. From the top menu bar, click Setup.
3. If you have not already logged in, enter your administrator password at the
prompt and click OK.
4. From the Setup menu, click Advanced.
5. On the Advanced page, you have the following options:
•
Force Safe Search check box: Select this check box to force all supported
search engines to use safe search. If you select this check box and a user
on this computer uses an unsupported search engine (such as
www.webcrawler.com), the user might be able to get results for searches
for offensive content.
Clear this check box to enable users on this computer to search the
Internet using any search engine, and not require search engines to use
safe search. If you clear this check box, the Block Unsafe Search check box
is unavailable.
•
Block Unsafe Search
check box: Select this check box to prevent users on
this computer from searching the Internet using a search engine that
does not support safe search. Clear this check box to allow users to
search the Internet with any search engine.

Filtering Secure Traffic
K9 Web Protection enables you to filter Internet traffic that uses the Hypertext
Transfer Protocol (HTTP) and Hypertext Transfer Protocol Secure (HTTPS)
protocols. HTTP is the most common protocol; HTTPS is referred to as a secure
protocol because it uses encryption to prevent third parties from intercepting and
reading the traffic between two entities, such as you and your on-line bank.
To prevent users on your computer from accessing objectionable content using the
HTTPS protocol, you must configure K9 Web Protection to filter HTTPS traffic as
discussed in this section.
To filter secure traffic:
1. Start K9 Web Protection as discussed in "Logging in to K9 Web Protection" on
page 21.
2. From the top menu bar, click Setup.

Blocking Web Sites Using URL Keywords
K9 Web Protection enables you to block access to Web pages based on keywords
in the Web page URL. You can, for example, block any Web page that has the
word sex in the URL.
To match, the entire, exact keyword has to be in the URL.
For example, if you enter sex, only URLs like www.sex.com, www.sex.org, and
www.sex.net will be blocked. To make your keywords more flexible, use the *
(asterisk) wildcard character. The * wildcard character can be used at the
beginning, end, or both ends of a word but not in the middle of a word.
The following table shows examples.
Example URL keyword
Description
sex*
Blocks URLs that start with sex, such as
www.sexy.com, www.sex-pix.org, and so on.
*sex
Blocks URLs that end with sex, such as
www.bobsex.com, www.strangesex.net, and so on.
*sex*
Blocks URLs that contain the word sex, such as
www.strangesexypeople.com,
www.sexinspace.com, and so on.
se*y
Not valid. Do not use an asterisk character in the
middle of a URL keyword.
Note:
•
Regardless of the URL keywords you configure, URLs are still blocked
if they belong to a category you chose to block or if the Web site is on
the always block list.
•
You also have the option of hiding the blocked keyword on the
exception page that displays when a user attempts to access a Web
page. This is useful if the keyword itself is offensive and you do not
want it displayed.
