There are different options available like "Content Matching Options", "Content Type", "ActiveX Blocking", "Port Setting", "Rating Systems" and "Actions"

1. Content Matching Options -

this option is helpful in controlling and blocking access to the web based on matching content and which works on different criterias:-

a. Search in Site Name -

The site name or url typed would be checked if it is listed in the restricted or blocked categories.

b. Search in HTML Tags -

f. Reserved Word Threshold Level -

This is a threshold level/limit set within the software that keeps a count of how many times a restricted or blocked word/s appears, if the set word/s have appeared as per the default value or more the access to the web is blocked or restricted and vice versa.

Content Type -

This option is helpful in controlling and blocking access to the web based on the type of content and which works on different criterias:-

a. Block Images -

Images on websites will be blocked from being viewed

i) Saving on Internet Bandwidth -

For example - to view an image that we like, we would click on it and enlarge it as a result eating up internet bandwidth.

ii) Secure -

The system and data from malwares like spywares, adwares, trojans, etc... - that creep onto the system when surfing and exploit vulnerabilities of the operating system and the applications installed on them.

iii) Degradation of the system (performance).

b. Block Applications -

Applications on websites will be blocked from being run / executed

i) Saving on Internet Bandwidth -

For example - to view an image that we like, we would click on it and enlarge it as a result eating up internet bandwidth.

ii) Secure -

The system and data from malwares like spywares, adwares, trojans, etc... that creep onto the system when surfing and exploit vulnerabilities of the operating system and the applications installed on them.

iii) Degradation of the system (performance).

c. Block eMails (RFC 822) -

Messages of RFC 822 would be blocked by default.

d. Block Audio files -

Audio files on websites will be blocked from being run / executed.

i) Saving on Internet Bandwidth -

for example - listening to a audio available on the website, we would click on it and start listening as a result eating up internet bandwidth.

ii) Secure -

iii) Degradation of the system (performance).

e. Block Video files -

Video files on websites will be blocked from being run / executed.

i) Saving on Internet Bandwidth -

For example - to view and listen to a video available on the website, we would click on it and start viewing and listening as a result eating up internet bandwidth.

ii) Secure -

iii) Degradation of the system (performance).

ActiveX Blocking -

ActiveX is a technology developed by Microsoft. With an ActiveX-enabled browser, ActiveX controls can be downloaded as part of a Web document to add functionality to the browser (similar to Java applets).

a. Java Applets -

Java is a programming language from Sun Microsystems and in which an applet is written, it can be included in an HTML page, much in the same way an image is included in a page. When you use a Java technology-enabled browser to view a page that contains an applet, the applet's code is transferred to your system and executed by the browser. For example - to enhance interactive control, primarily in Web browsers and other network-oriented interactive software applications.

b. Scripts (Java and VB) -

Is a list of commands that can be executed without user interaction, to automate certain application tasks or to work in a particular computing environment/scenario. So, when any script be it Java or VB (Visual Basic) is found to contain any malicious code, it is blocked.

This option is very useful in blocking programs that trigger or execute themselves when a website is being viewed.

c. Check for virus -

This is the default action set. This option scans and blocks all activities carried out while browsing (reading of data on the website, downloading the files, etc...) if found to contain any malicious code.

Port Setting -

Internet Access (HTTP Port) - 80,8080,3128,6588,4480,88.

These are the different ports defined within the software that are monitored for any data transfer that happens through them and if it contains any malicious data, it is blocked. You can add or delete the ports as per your requirements.

Rating Systems -

This option is not enabled by default. When enabled, this option allows each user or the administrator to set for each user, of how he/ she should access content on the web. These suggestions (advice) are laid down by World Renowned Organisations that cater to Content Filtering on the Internet, viz. RSACi, ICRA, SafeSurf.

a. RSACi -

Based on the study and work of Dr.Donal F. Roberts of Stanford University on the effects of media on children for nearly 20 years certain guidelines were laid, based on which "Recreational Software Advisory Council" (RSAC) was formed. Is a rating service of websites for content on the Internet.

b. ICRA - "Internet Content Rating Association" (ICRA) -

came into existence to protect children from harmful content on the internet. Is a global, cross-cultural filtering and rating service of websites for content on the Internet.

c. SAFESURF -

Designed with inputs from millions of users (parents) and Net Citizens to empower each family to make informed decisions concerning accessibility of content on the Internet.

6. Actions -

All of the above criteria are checked when enabled and if any violation is found appropriate action is taken.

a. Log Violations -

All violations are logged for easy administration and for future reference.

b. Shutdown program in 30 seconds -

If any of the rules/policies that are defined are found to be violated, then the software has a in-built functionality to automatically shutdown the program (browser) in 30 seconds.

iii) Time Restriction -

This option is set as per requirement. This option helps to customize the access to the web based on time or as per the day of the week or daily, for example - access to the web should be allowed everyday only during lunch hours and blocked otherwise.

Block Web Access:-

The “Block Web Access” option can be found between the “Start” and “Settings” options and enables you to block the web access completely (no internet access at all).

When enabled, it blocks access to the web completely. If the need arises, access to the web can be given on a conditional basis, for example - access to the web can be given only to certain websites like www.hotmail.com, yahoo.*, gmail.com, etc... and not others.
