What are browser cookies used for?
Table of Contents
HTTP cookies, or internet cookies, are built specifically for Internet web browsers to track, personalize, and save information about each user’s session. A “session” just refers to the time you spend on a site. Cookies are created to identify you when you visit a new website.
When you visit a website that uses cookies, a cookie file is saved to your PC, Mac, phone or tablet. It stores the website’s name, and also a unique ID that represents you as a user. That way, if you go back to that website again, the website knows you’ve already been there before.
What are the security implications of cookies?
Yet, depending on how cookies are used and exposed, they can represent a serious security risk. For instance, cookies can be hijacked. As most websites utilize cookies as the only identifiers for user sessions, if a cookie is hijacked, an attacker could be able to impersonate a user and gain unauthorized access.
How does a browser get a cookie?
When a user visits a website or takes certain actions on a website, a piece of data is transferred from the site and stored within the web browser that the person is utilizing. As someone browses the web, going from site to site, they sometimes pick up many cookies from multiple websites.
In respect of cookies, this means that:
- the user must take a clear and positive action to give their consent to non-essential cookies – continuing to use your website does not constitute valid consent;
- you must clearly inform users about what your cookies are and what they do before they consent to them being set;

Why are cookies called cookies?
The name cookie is derived from the Dutch word koekje, meaning “small or little cake.” Biscuit comes from the Latin word bis coctum, which means, “twice baked.” A small amount of cake batter was baked to test the oven temperature.
What are the two main security concerns with cookie?
As an Internet user, it’s wise to understand the risks of cookies so that you can view and delete them when necessary.
- Privacy Invasion. For most Internet users, privacy is their primary concern when it comes to Internet cookies.
- Cookie Fraud.
Cookies (files stored locally which identify users/link them to sites) are another potential attack vector. Like the browsing history, they can reveal where you go and what your account name might be.
The origin domain of a cookie is the domain of the originating request. If the origin domain is an IP, the cookie’s domain attribute must not be set. If a cookie’s domain attribute is not set, the cookie is only applicable to its origin domain.
Do all websites need cookie warning?
Every website that collects user data should have cookie consent banners or privacy notices. This applies to businesses and websites around the world. GDPR law applies to WordPress.com sites and plugins that process and store data.
What should a cookie policy contain?
A Cookies Policy is used to inform your site’s visitors that you’re using cookies on your website, web app, or mobile app. It should include information about the types of cookies you’re using, how you’re using them, and how users can control the way cookies are managed on their devices.
