Description

This module uses highly advanced algorithms based the occurrence of specific words or phrases in the content of the Web site to block Web sites containing pornographic or offensive material. This feature is extremely beneficial to parents because it prevents kids from accessing Web sites containing harmful or restricted content. Administrators can also use this feature to prevent employees from accessing non-work-related Web sites during work hours. The Web Protection module also comes with advanced reporting features, which keep a track of the Web sites that were blocked by ‘e Scan. You can view the Web Protection feature logs and the Popup Filter logs from the Report section of the Web Protection tab.

 

 

When you click the Web Protection icon, the tabbed page provides you with the information regarding its status, options for configuring the module, and links to reports on the Web sites that were scanned or blocked by the module.

The tabbed page shows two sections: Configuration and Reports. These two sections are described as follows:

ActiveX Blocking An ActiveX control is component program that can be automatically downloaded and executed by a Web browser. It is similar to a Java applet. ActiveX controls may include malicious code and therefore may pose as a security hazard.
  1. Java Applets - Java Applets are programs that are written in the Java programming language. These applets can be embedded in an HTML page and can be view from a Java enabled Web browser. Applets enhance the interactivity in Web pages and provide users with an enhanced Web experience. However, some applets contain malicious code that may either disrupt the processes running on your computer or steal sensitive information. You can select the Java Applets check box to block applets from being downloaded to your computer.
  2. Scripts (Java & VB) - Scripts are usually written in scripting languages such as JavaScript and VBScript. A script is a list of commands that can execute without user input. With the help of scripts, you can automate certain tasks within an application to work in a particular computing scenario. Hackers often use malicious script to steal information about the victims. When you select the Scripts (Java & VB) check box, ‘e Scan blocks any script that contains any malicious code from being downloaded to your computer from the Internet.
  3. Check for Virus - [Default] This check box is selected by default. You should select this check box if you need ‘e Scan to scans and blocks all Web sites that contain malicious code.


Actions This section helps you select the actions that ‘e Scan should perform when it detects a security violation.
  1. Log Violations - [Default] This check box is selected by default. You should select this check box if you need Web Protection to log all security violations for your future reference.
  2. Shutdown Program in 30 Secs. You should select this check box if you need Web Protection to shut down the browser automatically in 30 seconds when any of the defined rules or policies is violated.


Port Setting This section helps you specify the port numbers that ‘e Scan should monitor for suspicious traffic.
  • Internet Access (HTTP Port) - Web browsers commonly use the port numbers 80, 88, 8080, 3128, 4480, and 6588 for accessing the Internet. You can add port numbers to the Internet Access (HTTP Port) box to monitor the traffic on ports.


Content Type This section helps you block content based on their type.
  1. Block Images. You should select this check box if you need Web Protection to block images that appear on Web sites.
  2. Block Applications. You should select this check box if you need Web Protection to block applications on Web sites from executing.
  3. Block E mails (RFC 822). You should select this check box if you need Web Protection to block messages belonging to the RFC 822 format.
  4. Block Audio files. You should select this check box if you need Web Protection to block audio files on Web sites from executing.
  5. Block Video files. You should select this check box if you need Web Protection to block video files on Web sites from executing.


III) Define Time Restriction - This section helps you define policies to restrict access to the Internet.
Note: This tab is not displayed if you select the Block Web Access option on the Filtering Options tab.

 

 

Enable Time Restrictions for Web Access: You should select this check box if you need to place restrictions on when a user can access the Internet. All the elements on this page are disabled by default. They are enabled only when you select this option. In addition to this check box, the Define Time Restriction tab displays a grid, which contains the schedule for allowing Internet access.


Timing Grid: When you select the Enable Time Restrictions for Web Access check box, the Timing Grid is enabled.
Note: You can activate or block Web access or deactivate time restrictions for a minimum duration of 30 minutes and not less than that.


Rows: The gird has seven rows; each row headed by a day of the week. The first row has the heading as “Sunday,” the next row has the heading as “Monday,” and so on up to “Saturday.” These row headings are displayed on the left of the grid.
Columns: The grid has 48 columns of colored blocks. Each block represents 30 minutes. On the grid, the column heading 00 represents 00:00 hours. The next heading 01 represents 01:00 AM, and so on up to 12 (last column heading), which represents 11:59:59 PM.
For example, on the first row, the block to the immediate right of the line labeled 02 represents 30 minutes. If you count two blocks to the right of 02 on the same row, this will represent 1 hour.


The grid is divided into two groups as follows:
00 to 12: This group comprises 24 colored blocks. The first block has the heading as 00, the third block has the heading as 01, and so on up to 12 in increments of 01. This group represents the time from 00 hours (i.e, 12:00 A.M. [midnight]) to 12:00 P.M. (noon).
01 to 12: This group also comprises 24 colored blocks. The next block has the heading as 12, the third block has the heading as 01, and so on up to 12 in increments of 01. This group represents the time from 12:00 P.M. (noon) to 11:59:59 P.M. (midnight).


 

 


Three option buttons are displayed below. These buttons are disabled initially. They are enabled only when you select the Enable Time Restrictions for Web Access check box.
Active [Default]: This option has a color code of green. You should click this option when you want to enable Web access for a given period of time.
Inactive: This option has a color code of blue. You should click this option when you want the Web Protection to become inactive for a given period of time.
Block Web: This option has a color code of red. You should click this option when you want to block Web access for a given period of time.


How to Use the Grid-based Timing feature (Timing Grid)
You can use the Timing Grid to specify the duration for which the Web Protection module should be active, inactive, or blocked. For this, you should select the required option button and then click the block corresponding to the time on the grid.


For example, if you want to block Web access from say, 01:00 A.M. to 03:30 A.M. on Thursday, you should perform the following steps.
1. On the Define Time-Restriction tab, click Block Web.
2. Next, on the grid, on the row having the heading as Thursday, find the block to the immediate right of the line labeled 01 (00 to 12 group), and then click it. This is the block corresponding to 01:00 A.M.
3. Then, on the same row click the next four blocks adjacent to this box. Ensure that the last block is the one next to the line labeled 03 on the grid (on the same row). This will block Web access from 01:00 A.M. to 03:30 A.M. every Thursday.
Note: You can also color a range of blocks by clicking the first block and then dragging the pointer to the last block in the range.
