How NIS and NPF handle cookies
This document describes the Norton Internet Security (NIS) and Norton Personal Firewall (NPF) features that handle cookies (the files that Web sites place on your hard disk).
NIS and NPF provide the following options for handling cookies:
Handling alerts: When you see an alert that indicates that a Web site is attempting to place a cookie on the hard disk, use the options on the alert window to permit or prevent this action. For more information on this subject, read the section "Cookie alerts" in this document.
Displaying alerts: You may configure NIS or NPF to display an alert every time that a Web site attempts to place a cookie on the hard disk, or only sometimes. For more information on this subject, read the sections "Blocking Cookies" and "How to change the Cookie Blocking settings" in this document.
Blocking all cookies: If you want to prevent all cookies from being placed on your hard disk, read the sections "Blocking Cookies" and "How to change the Cookie Blocking settings" in this document.
Blocking or permitting cookies from specific Web sites: You may prevent specific Web sites from placing cookies on your hard disk by configuring the specific Web site on the Web Content tab under Options in NIS or NPF. For more information on this subject, read the sections in your user manual that refer to the options "Information about your browser" and "Information about visited sites."
Blocking confidential information in cookies: Occasionally, cookies may include confidential information. If you want to prevent that information from being accessed by a Web site, use the Privacy settings to specify the confidential information that you want blocked. For more information on this subject, read the sections in your user manual that refer to Privacy Control. The options in the Privacy Control feature apply to all confidential information that is sent from your computer, regardless of whether that information is sent from a cookie or from other sources.
A Cookie Alert screen indicates that a Web site has attempted to place a file on your hard disk.
If you choose Permit, the Web site saves the cookie to your hard disk. When you next visit that same Web site, the site reads that information. Most cookies are harmless. In some cases, however, you may want to block cookies to prevent the collection of information about your Internet usage, or filter cookies to prevent Web sites from accessing confidential information.
If you choose Block, the cookie is not placed on the hard disk.
When you see the alert, choose one of the following:
To block this cookie this time, select "Block."
To block this cookie every time that you visit this Web site, select "Block" and "Always use this action." Selecting these options creates a rule so that you do not see another cookie alert later for this Web site. If you do not select "Always use this action," a cookie alert screen will appear each time that you try to access this Web site.
To permit this cookie this time, select "Permit."
To permit this cookie every time you visit this Web site, select "Permit" and "Always use this action." Selecting these options creates a rule so that you do not later see another cookie alert for this Web site. If you do not select "Always use this action," a cookie alert screen will appear every time that you try to access this Web site.
Use the Cookie Blocking setting to instruct NIS or NPF on whether you want a cookie alert screen to appear each time that a Web site attempts to place a cookie on your hard disk, and to configure NIS or NPF for blocking or permitting cookies.
NIS and NPF have three Cookie Blocking options, which are accessible in the Customized Privacy Control options:
None: Allow cookies (recommended): Allows cookies without any alerts. This is the default setting. When you use this option, you do not see a cookie alert screen each time that a Web site places a cookie on your hard drive.
Medium: Prompt me each time: Alerts you each time that a cookie is encountered. You choose whether to permit the cookie.
High: Block cookies:This option blocks all cookies. Note the exceptions in the section "How to block all cookies."
How to block all cookies
Though you can set a specific security level for cookie blocking for each user, you can also set exceptions to that security level in the Web Content tab that is accessible from Options on the main NIS or NPF window.
How you configure these two settings determines whether you block all cookies, some cookies, or none:
If you want to block all cookies from being placed on your computer, regardless of your NIS or NPF settings or the user, the browser must be reconfigured. See the document, Norton Internet Security allows Web sites to place cookies, for instructions on preventing cookies from being placed on your computer. Note that if you block cookies, you may not be able to access some Web sites that require a cookie.
If you want to block all cookies except for those Web sites that have an exception in the NIS or NPF Web Content settings, use the High setting for Cookie Blocking.
If you want to block all cookies for a specific NIS user, use the High setting for Cookie Blocking for the user that you specify and ensure that there are no exceptions in the NIS or NPF Web Content settings for specific Web sites.

Open Norton Internet Security or Norton Personal Firewall.
In the left column, click Status & Settings.
Check the "Settings for" option and select the appropriate user.
Click Privacy Control, and then click Configure.
Click Custom Level.
Change the Cookie Blocking options to the desired setting.
