What are cookies?
Cookies are produced when a user's browser retrieves a website. The website transmits data to the browser, which then saves it as a text file. Once the user returns to the same website, the computer retrieves and sends this file to the server.
The server also seems to use session id to display analysis of user page activities so that users can quickly pick up under which they left off on the customer's pages. Web pages do not have any' memory' by default. Muffins tell the server whether the pages show the customer so that the user does not have to remember or actually the site.
Difference between cookies and Session cookies:
Session users should be able users to be understood within a website, so that any page changes, items, or data offerings you make do remember from page to page. The online ordering feature of any e-commerce site is the most obvious form of this functionality. When you visit one page of an archive and select some items, the session cookie remembers your selection so that when you are ready to check out, your shopping cart will include the items you selected. If you click Payment process without using user data, the new page will not recognize your activities on previous pages, and your shopping basket will always be empty.
Life without Cookies :
They are used to speed up and simplify online browsing by equipping given web websites to remember your personality, such as your IP address or passwords, as well as your individual preferences, such as when Amazon suggests a book or music CD that is similar to what you were gazing for on your previous visit.
How Secure are Cookies? How Long Does a Cookie Last?
Examine all responses where a cookie is set by the application (using the Set-cookie directive) and trap them using an intercepting proxy or data intercepting plug. Then, examine the cookie for the following:
- Secure Attribute: A cookie must be passed through an IPsec tunnel whenever it includes sensitive data or is a journey token. For instance, after authenticating into applications and defining a session token with the help of a cookie, make sure the session token is marked with the "secure" flag. If it's not, the browser would agree to send it via an unencrypted, like HTTP, and an adversary could trick users into submitting their cookies over that channel.
- HttpOnly Attribute - Even though not all browsers allow it, this attribute should always be set. This attribute helps to protect the cookie from being accessible by a client-side script; it reduces some exploitation vectors but does not completely eliminate the risk of cross-site scripting. Verify whether the "; HttpOnly" tag is set.
