How to Restrict Web Browsing Using Internet Explorer

How to Restrict Web Browsing Using Internet Explorer

Regulating web browsing can prevent children (and workers) from accessing dangerous content on the internet, or having to make judgment calls over suitable relationships in chat-rooms. The fact is, web sites, chat-room users and downloaded programs may not have the best interests of you and your family at heart. The unscrupulous may try to manipulate the people you care about, or try to gain trust, which may result in unacceptable access to your family, your computer, or personal information.

You can block access to unwanted web content. Here's how to do so with a basic Parental Control tool included free with Windows: Content Advisor. We also examine other software titles with extended features that can help keep your family in safe territory.



Steps

  1. 1
    Open Internet Explorer by clicking on the "e" icon located at the bottom left of the computer sceen. Once the Internet Explorer window opens, look toward the upper right area for the "Tools" button, click on it and then click on Internet Options at the bottom.

Tips

  • If your children (or any other Internet browser in your home) feel that their Internet options are being limited, spend some time reminding them what happens to computers that are completely unprotected, and present the Internet filter as just another part of a good security setup.
  • Restricting a child's web usage when they are used to unrestricted access may result in negative behavior. Try to to install an Internet filter at an early stage to get them used to it.
  • Content Advisor only filters Internet Explorer, so if a family member installs another web browser such as Firefox, filtering will not be effective. To prevent a user installing another browser (such as Firefox) and bypassing IE's filtering, create another User on your computer, and assign it limited user powers. Get the other users to login using the new user ID, and their ability to install new programs is restricted.
  • Resourceful children may try to use "hacks" to bypass your controls:

    • Free proxy service websites (search on google for "free web proxy") can hide further webpage browsing from parental controls. Most parental control software will automatically block access to these sites, but check out History logs to view any attempts, and talk to your child to generate agreement on what surfing is acceptable.
    • If the child logs in to the computer using an administrator account, they may attempt to turn off Content Advisor by deleting registry settings. Create for them a new account (with limited powers) to restrict their ability to edit the registry.
  • Content Advisor may have uses but other software titles have more powerful features:

    • Control what programs and games are run.
    • Restrict computer use to certain times or days.
    • View a list of visited websites.
    • Control which websites are accessed.
  • Some other programs to consider are as follows:

    • K9 Web Protection - a leading parental control software resource. Tons of tips and guides for parents to help safeguard the online welfare of their children.
    • SafeEyes - This is what some schools are installing.
    • CyberPatrol - Perhaps the most used program at home. This program also can control access to programs installed on the computer.
    • ContentProtect - Includes a remote control feature.
    • Integrated Tools - If you are a AOL, MSN or Earthlink subscriber, or you own Norton Internet Security or ZoneAlarm Internet Security, you already have some parental control tools, as they are integrated into the software.

Warnings

  • This restricts ALL users not specific users
  • All parental-control programs sometimes over-block or under-block websites. Read software reviews to minimize the risk of installing a program that blocks too many safe sites, or allows access to too much dangerous content.
  • Often web browsers are the target of many vulnerabilities and loopholes, particularly popular ones such as Internet Explorer or Firefox are often the target of such exploits, if you feel uncomfortable about this then perhaps you should try a less popular browser like Opera or Konqueror (Linux/Macintosh) which offer different codebases and features. It should be noted however that most security compromises are a result of unsafe computing habits.

    • Ask your family to:

      • Scan all downloads with your virus checker.
      • Avoid programs and services that have not gained your trust.
    • Install a program such as Windows Security Essentials to block webpages that are known to try to gain access to your computer.
  • If you have a router/modem which provides "always on" internet access, parental control software (indeed Windows itself) can be bypassed by a user booting a custom operating system from a removable drive (this doesn't apply to internet access through a simple USB or dialup modem, where users don't have access to ISP login details).

    • Consider installing a physical proxy that controls all web requests at access level. This will probably involve installing a more costly router/firewall with extended features, unless you already have one.

Things You'll Need

  • Windows
  • Internet Explorer 6 or later

How Parents Can Block Certain Websites from Children at Home

How Parents Can Block Certain Websites from Children at Home

[For non-techie parents who have a computer at home and are worried about their kids safety online.]
block websites at homeA mother recently wrote saying she is very concerned that her young children are spending too much time on websites like Orkut, MySpace and Facebook.
Her worries are not just about children wasting time on the Internet - it’s more about the activities that children are doing on these sites. She is concerned that children could be interacting with complete strangers (or online predators) and even sharing personal information.
And with some news reports saying that criminal activities could have been planned on Orkut, the mother has finally made up her mind to restrict access to Orkut and some other websites on the home computer.
The only problem is that she has absolutely no clue about how to block websites – parental control software like Net Nanny or Norton Internet Security are pretty good but they cost money.
Now before you take this extreme step of blocking website (that is very likely to be opposed by children), try a few things:
  1. Educate your children about the dangers of sharing information online with strangers. Family members should talk in detail about privacy and the web.
  2. Place the computer in the living area of your home from where you can easily see the screen so you’ll have some idea about activities that children are doing on the computer including the websites they are visiting frequently.
  3. Orkut is an open social network – that means you can easily see who’s in the friends’ list of your children and what kind of text notes (or scraps) are they exchanging with each.
Finally, to block websites on your home computer without investing in expensive software, here’s the trick (for Windows PCs):
Step 1: Click the Start button and select Run. Now type the following text in that Run box:
notepad c:\WINDOWS\system32\drivers\etc\hosts
Step 2: You will see a new notepad window on your screen containing some cryptic information. Don’t panic. Just goto the last line of the file, hit the enter key and type the following:
127.0.0.1 orkut.com
127.0.0.1 facebook.com
127.0.0.1 myspace.com
Save the file and exit. That’s it. None of the above sites will now open on your computer.
You can block as many websites as you like with the above technique. If you want to remove the ban later, open the same file as mentioned in Step 1 and delete the above lines.
Pretty simple but remember, our children are also very smart. And there are some popular ways to unblock websites.
