· Move the slider up for a higher level of security or down for a lower level of security.

· To specify custom security settings for the selected zone, click the Customize Level button. To set the options for a particular security level back to their original settings, click the Default Level button.

What you need to know about security zones

Internet Explorer divides your Internet world into zones, so that you can assign a Web site to a zone with a suitable security level.

You can tell which zone the current Web page is in by looking at the right side of the Internet Explorer status bar. Whenever you attempt to open or download content from the Web, Internet Explorer checks the security settings for that Web site's zone.

· Internet zone: By default, this zone contains anything that is not on your computer or an intranet, or assigned to any other zone. The default security level for the Internet zone is Medium.

· Local intranet zone: This zone typically contains any addresses that don't require a proxy server, as defined by the system administrator. These include sites specified on the Connections tab, network paths (such as \\server\share), and local intranet sites (typically addresses that don't contain periods, such as http://internal). You can also add sites to this zone. The default security level for the Local intranet zone is Medium.

· Trusted sites zone: This zone contains sites you trust - sites that you believe you can download or run files from without worrying about damage to your computer or data. You can assign sites to this zone. The default security level for the Trusted sites zone is Low.

· Restricted sites zone: This zone contains sites you don't trust - that is, sites that you're not sure whether you can download or run files from without damage to your computer or data. You can assign sites to this zone. The default security level for the Restricted sites zone is High.

In addition, any files already on your local computer are assumed to be very safe, so minimal security settings are assigned to them. You cannot assign a folder or drive on your computer to a security zone.

If you want, you can change the security level for a zone; for example, you might want to change the security setting for your Local intranet zone to Low. Or, you can customize the settings within a zone from the default settings in Low, Medium Low, Medium, and High.

Protecting your computer from unsafe software

When you download or run programs from the Internet, you want to know that the program comes from a known, reliable source. That's why, when you choose to download a program from the Internet to your computer, Internet Explorer uses Microsoft Authenticode technology to verify the identity of the program. Authenticode technology verifies that the program has a valid certificate: that the identity of the software publisher matches the certificate, and that the certificate is still valid. Note that this does not prevent a poorly written program from being downloaded or run on your computer, but it does reduce the chance of someone misrepresenting a program that is intended to be malicious or intentionally harmful.

You can specify different settings for how Internet Explorer handles downloading programs and files, depending on the zone it is coming from.

For example, you might be confident that anything you download within your corporate intranet is safe. So, you might set your security settings for your Local intranet zone to a low level to allow downloading with little or no prompting. If the source is in the Internet zone or the Restricted sites zone, you may want your security levels set to Medium or High. Then, you'd be prompted with information about the program's certificate before it is downloaded, or you may not be able to download it all.

If you've already enabled Content Advisor, click Settings, and then type the supervisor password.

· Click a category in the list, and then drag the slider to set the limits you want to use.

· If a supervisor password has not already been set up for your computer, you are prompted to create one.

· You might want to write down your supervisor password. You will need to type it any time you change the Content Advisor settings.

· To prevent others from visiting objectionable Web sites that don’t use ratings labels, click the Approved Sites tab, and change the settings as appropriate.

Using secure Internet sites for transactions

Many Internet sites are set up to prevent unauthorized people from seeing the information that is sent to or from those sites. These are called "secure" sites. Because Internet Explorer supports the security protocols used by secure sites, you can send information to a secure site with safety and confidence. (A protocol is a set of rules and standards that enable computers to exchange information.)

When you visit a secure Web site, it automatically sends you its certificate, and Internet Explorer displays a lock icon on the status bar. (A certificate is a statement guaranteeing the identity of a person or the security of a Web site. For more information, see the Related Topic below.)

If you are about to send information (such as your credit-card number) to an unsecure site, Internet Explorer can warn you that the site is not secure. If the site claims to be secure but its security credentials are suspect, Internet Explorer can warn you that the site might have been tampered with or might be misrepresenting itself.

· Some secure sites require a higher level of connection security than what you might have installed on your computer. In the United States or Canada, you can upgrade to 128-bit secure connection support, however due to legal restrictions this software is not available worldwide.

International users may still be able to conduct 128-bit transactions without this upgrade, if the server supports Server Gated Cryptography (SGC). SGC is available worldwide for qualifying sites. However, some United States and Canada financial sites that do not use SGC may require the 128-bit upgrade be installed on your computer.

Protecting your identity over the Internet

You can use a personal certificate to protect your identity over the Internet. A certificate is a statement guaranteeing the identity of a person or the security of a Web site. You can control the use of your own identity by having the private key that only you know on your own system. When used with mail programs, security certificates with private keys are also known as "digital IDs."

· A "personal certificate" is a kind of guarantee that you are who you say you are. This information is used when you send personal information over the Internet to a Web site that requires a certificate verifying your identity.

· A "Web site certificate" states that a specific Web site is secure and genuine. It ensures that no other Web site can assume the identity of the original secure site.

How do security certificates work?

Securely sharing personal information

Profile Assistant can save you from having to enter the same information repeatedly, such as your address or e-mail name, every time you visit a new Web site that requests such information. It does this by storing the information on your computer.

None of this information can be viewed on your computer, or shared with others, without your permission.

When a Web site requests information from Profile Assistant, the request will tell you:

· What information the site is requesting from Profile Assistant, so you can exclude information if you want.

· Whether this site has a secure connection (Secure Sockets Layer or SSL). If it does, you can verify the site's certificate.

You can encrypt your personal information, both when it is transmitted and as it is stored on your computer.

What you need to know about cookies

Some Web sites store information in a small text file, called a "cookie," on your hard disk.

Cookies contain information about you and your preferences. For example, if you inquire about a flight schedule at an airline's Web site, the site might create a cookie that contains your itinerary. Or it might only contain a record of which pages within the site you visited, to help the site customize the view for you the next time you visit.

Only the information that you provide, or the choices you make while visiting a Web site, can be stored in a cookie. For example, the site cannot determine your e-mail name unless you choose to type it. Allowing a Web site to create a cookie does not give that or any other site access to the rest of your computer, and only the site that created the cookie can read it.

Internet Explorer is set up to allow the creation of cookies; however, you can specify that you be prompted before a site puts a cookie on your hard disk, so you can choose to allow or disallow the cookie; or you can prevent Internet Explorer from accepting any cookies.

You can specify different settings for different security zones. For example, you might want to allow Web sites to create cookies if they are in your Trusted sites or Local intranet zone, prompt you before creating cookies if they are in your Internet zone, and never allow cookies if they are in your Restricted sites zone.
