Internet Cookies




A cookie (called an Internet or Web cookie) is the term given to describe a type of message that is given to a web browser by a web server. The main purpose of a cookie is to identify users and possibly prepare customized Web pages or to save site login information for you. When you enter a website using cookies, you may be asked to fill out a form providing personal information; like your name, email address, and interests. This information is packaged into a cookie and sent to your Web browser, which then stores the information for later use. The next time you go to the same Web site, your browser will send the cookie to the Web server. The message is sent back to the server each time the browser requests a page from the server. A web server has no memory so the hosted website you are visiting transfers a cookie file of the browser on your computer's hard disk so that the site can remember who you are and your preferences. This message exchange allows the Web server to use this information to present you with customized Web pages. So, for example, instead of seeing just a generic welcome page you might see a welcome page with your name on it.

Most Internet cookies are incredibly simple, but they are one of those things that have taken on a life of their own. Cookies started receiving tremendous media attention back in 2000 because of Internet privacy concerns, and the debate still rages.On the other hand, cookies provide capabilities that make the Web much easier to navigate. The designers of almost every major site use them because they provide a better user experience and make it much easier to gather accurate information about the site's visitors.


    Cookies normally do not compromise security, but there is a growing trend of malicious cookies. These types of cookies can be used to store and track your activity online. Cookies that watch your online activity are called malicious or tracking cookies. These are the bad cookies to watch for, because they track you and your surfing habits, over time, to build a profile of your interests. Once that profile contains enough information there is a good chance that your information can be sold to an advertising company who then uses this profile information to target you with interest specific adverts. Many antivirus programs today will flag suspicious spyware or adware cookies when scanning your system for viruses.


First and Third-Party Cookies

When choosing a privacy setting in your browser, two terms you will see are "first-party cookies" and "third-party cookies". First party cookies are those cookies that originate from (or be sent to) the Web site you're currently viewing. These types of cookies usually will contain information about your preferences for that particular Web site. These cookies are usually Third-party cookies originate from (or will be sent to) a Web site that is not the site you are visiting. For example, if the Web site you are on using third-party advertising those third-party advertising Web sites may use a cookie to track your Web habits for marketing purposes.
While some may simply choose to block all cookies, it can make Web surfing difficult if you do this. For example if you shop online, many e-commerce shopping carts that have been implemented with cookies will not work. Sites you frequently visit which enable you to personalize content also will not show your preferences when you visit if you delete or disable that cookie.
Most cookies, despite some misconceptions, are legitimate files and will not invade your privacy. Once you get in the habit of reviewing the cookies associated with your browser and manage them on your own by way of deleting malicious cookies or trying different browser privacy settings, you can still keep the good cookies that make surfing a breeze, yet keep the bad cookies that may be tracking your surfing habits off your system.
