Every website you visit now seems to display a warning such as "We use cookies to improve your experience. By your continued use of this site, you accept such use. To change your settings please see our policy." Usually, you have no chance to stop the cookies with only an "x" button that will just disable the message. And thus many users think web cookies a bad thing which might do harm to the privacy and security. So in this article, you are going to get some knowledge of cookies and decide if it’s bad or good.

First of all, what exactly is a browser cookie? Cookies are small text files that are put on your computer or mobile device by websites you visit or certain emails you open. It is not a .exe file and doesn’t have any ability to run scripts or other potentially malicious software on your computer, all it ever stores is information in text format. Cookies also have no ability to generate pop-up advertising or to send spam.

We can sort the cookies into two categories, session cookies and persistent cookies. Session cookies are only active during website visiting and are automatically deleted when you close the browser, not collecting information from your computer but do store information relevant to that particular visit; while persistent cookies, also known as permanent cookies, are stored in the browser until you delete them.

It seems that the persistent cookie, also the notorious tracking cookie is the primary concern that is violating the privacy and security. It is absolutely not comfortable that the advertisers get your interests and display the targeted ads to you all the time. Also, the cookies might be the vulnerable path that allows malicious webmasters to access the accounts and passwords.
