Cookie based authentication

A Cookie-based authentication uses the HTTP cookies to authenticate the client requests and maintain session information on the server over the stateless HTTP protocol. Here is a logical flow of the cookie-based authentication process: The client sends a login request with credentials to the backend server.

How are cookies used to authenticate?

Cookie-Based Authentication. Authentication is the process of exchanging user credentials for a piece of unique identification. In cookie-based authentication, this unique identifier (cookie) is created on the server-side and sent to the browser.

What is cookie vs token based authentication?

Cookies and tokens are two common ways of setting up authentication. Cookies are chunks of data created by the server and sent to the client for communication purposes. Tokens, usually referring to JSON Web Tokens (JWTs), are signed credentials encoded into a long string of characters created by the server.

Is a JWT a cookie?

JWT is simply a token format. A cookie is an HTTP state management mechanism really. As demonstrated, a web cookie can contain JWT and can be stored within your browser's Cookies storage. So, we need to stop comparing JWT vs Cookie.

Why should we use JWT instead of cookie-based authentication?

In both approaches the client side must securely save the “cookie” or the “jwt token”. The main difference is that in case of the JWT approach the server does not need to maintain a DB of sessionId for lookup.

Why is it called a cookie?

The term "cookie" was derived from an earlier programming term, "magic cookie," which was a packet of data programs that kept data unchanged even after being sent and received several times. Session cookies are also known as transient cookies or per-session cookies.

How do hackers use cookies?

The cookies are then used for post-exploitation and lateral movements. Cybercriminals can use them to change passwords and emails associated with user accounts, or trick the victims into downloading additional malware, or even deploy other exploitation tools such as Cobalt Strike and Impacket kit.

Are cookies better than JWT?

In modern web applications, JWTs are widely used as it scales better than that of a session-cookie based because tokens are stored on the client-side while the session uses the server memory to store user data, and this might be an issue when a large number of users are accessing the application at once.

What are the 3 types of computer authentication?

Authentication factors can be classified into three groups: something you know: a password or personal identification number (PIN); something you have: a token, such as bank card; something you are: biometrics, such as fingerprints and voice recognition.

Is JWT is OAuth?

JWT token vs oauth token: JWT defines a token format while OAuth deals in defining authorization protocols. JWT is simple and easy to learn from the initial stage while OAuth is complex. OAuth uses both client-side and server-side storage while JWT must use only client-side storage. JWT has limited scope and use cases.

Does Netflix use JWT?

Lately, Netflix has been partnering with device manufacturers to merchandise Netflix content to members as well as nonmembers, and sometimes from the partners' UI itself. For these integrations, we built specific APIs and we chose to use an open standard like JWT to better integrate with partner infrastructure.

What is cookies vs bearer token?

Cookies are always present once authenticated, while the Bearer token may be available only on some requests depending on the application. Note that this check only checks authentication type. It doesn't authenticate.

Is JWT better than OAuth?

JWT is suitable for stateless applications, as it allows the application to authenticate users and authorize access to resources without maintaining a session state on the server. OAuth, on the other hand, maintains a session state on the server and uses a unique token to grant access to the user's resources.

Can JWT be used without OAuth?

The simple fact is that JWTs are a great solution, especially when used in tandem with something like OAuth. Those benefits quickly disappear when used alone, and in many cases can result in worse overall security.

Is JWT really secure?

The general opinion is that they're good for being used as ID tokens or access tokens and that they're secure — as the tokens are usually signed or even encrypted. You have to remember though, that JWT is not a protocol but merely a message format.

How does a cookies work?

How Do Cookies Work? Computer cookies are small files, often including unique identifiers that web servers send to browsers. These cookies then can be sent back to the server each time your browser requests a new page. It's a way for a website to remember you, your preferences, and your habits online.

How does cookie encryption work?

When cookie encryption is enabled, the BIG-IP LTM system extracts the unencrypted cookie from the server response, encrypts it using a 192-bit AES cipher, and then encodes it using the Base64 encoding scheme. The BIG-IP LTM system then embeds the encrypted cookie into the HTTP response to the client.

What is the purpose of cookies?

Cookies are small pieces of text sent to your browser by a website you visit. They help that website remember information about your visit, which can both make it easier to visit the site again and make the site more useful to you.

What is the use of cookies in API testing?

Cookie testing is the type of software testing that checks the cookie created in the web browser. A cookie is a small piece of information that is used to track where the user navigated throughout the pages of the website.

What are the 3 types of cookies?

There are three types of computer cookies: session, persistent, and third-party. These virtually invisible text files are all very different. Each with their own mission, these cookies are made to track, collect, and store any data that companies request.

What is the advantage of cookies?

As a necessary part of web browsing, HTTP cookies help web developers give you more personal, convenient website visits. Cookies let websites remember you, your website logins, shopping carts and more.

How do cookies collect data?

Tracking cookies are cookies that are either set on a user's web browser by the website they are on or by a third party. These cookies track the user's online behaviour i.e. collect their data, such as clicks, shopping preferences, device specifications, location, and search history.

Are cookies encrypted by TLS?

A server can specify the Secure flag while setting a cookie, which will cause the browser to send the cookie only over an encrypted channel, such as a TLS connection.

Are cookies encrypted in https?

A cookie with the Secure attribute is only sent to the server with an encrypted request over the HTTPS protocol. It's never sent with unsecured HTTP (except on localhost), which means man-in-the-middle attackers can't access it easily. Insecure sites (with http: in the URL) can't set cookies with the Secure attribute.

Can cookie be hacked?

Like a phishing attack, cookie hijacking allows a cybercriminal to steal personal information like usernames, passwords, and other important data held within the cookie. If you enter your information while on the fake website, the criminal can then put that cookie in their browser and impersonate you online.
