How did you secure the REST API?

Making sure that you only accept queries sent over a secure channel, like TLS, is the first step in protecting an API (formerly known as SSL). End-to-end encryption is used when communicating with a TLS certificate to safeguard all API data and access credentials while they are in transit. Another step toward protecting a REST API is the use of API keys.

What are different ways to secure REST API?

5 fundamental strategies for REST API authentication

  • simple identification The simplest method to secure REST APIs is basic authentication, an HTTP-based authentication strategy.
  • API keys
  • HMAC security.
  • OAuth 2.0.
  • Connect with OpenID.
  • using a REST API for authentication.

How do you secure a REST API and how do you authenticate it?

Here are some of the best practices for securing your REST API:

  1. Using third-party certificates to guarantee client security.
  2. Account-Based HTTP Basic Authentication.
  3. HTTP Digest Authentication.
  4. API Key-Based Authentication
  5. Web Token Authentication Using Java (JWT)
  6. oAuth-Based Authentication

How do you secure rest data?

How to secure sensitive data at rest

  1. Locate and identify the data. Organizations must be aware of what data is sensitive, such as personal information, business information, and classified information, and where that data is stored, in order to best secure data at rest.
  2. Sort the data.
  3. Accept encryption.
  4. Safeguard the system.
  5. educate users.

How do you secure API calls?

Best Practices for Securing APIs

  1. Put security first.
  2. Manage your API inventory.
  3. Use a reliable solution for authentication and authorization.
  4. Use the least privilege principle.
  5. TLS traffic encryption is used.
  6. Remove any information that is not intended for sharing.
  7. Limit the amount of data you expose.
  8. Verify the input.

What type of authentication is used in REST API?

Basic authentication must be used with HTTPS/TLS. It is most effective when used for server-side only applications because it is simple to implement and supported by the majority of browsers. It can be strengthened by combining it with additional security measures.

What is difference between OAuth and JWT?

JWT is essentially a token format. JWT is a token that can be used with OAuth, an authorization protocol. OAuth utilizes both client-side and server-side storage. OAuth2 is the only option if you want to perform a true logout.

How do you authenticate an API?

You must be a verified user to make API requests. Authenticate API requests using basic authentication with your email address and password, with your email address and an API token, or with an OAuth access token.


  1. Password.
  2. API key.
  3. access token for OAuth.
  4. your authorization header is being viewed.

How does API security work?

Security on the API level operates by looking at the data entering the API environment. API security prevents attempts to break the application’s rules or let unauthorized users use it to access and steal private data.

How many ways we can secure Web API?

The three security measures we’ve covered here are accepted practices for various circumstances. HMAC authentication is frequently used to protect open APIs, whereas digital signature is appropriate for two-way server-to-server communication.

Should I use JWT or OAuth2?

OAuth2 has lots of flexibility. It takes very little time and effort to implement JWT. Choose OAuth2 if your application requires this level of adaptability. But implementing OAuth2 is a waste of time if you don’t need this use-case scenario.

What is better than JWT?

One of the most popular designs, PASETO, or Platform Agnostic Security Token, is widely regarded by the community as the most secure substitute for JWT.

What is OAuth stands for?

Open authorization, also known as OAuth, is a widely used authorization framework that enables you to give permission for an application to interact with another on your behalf without disclosing your password. By giving access tokens to third-party services without disclosing user credentials, it achieves this.

What is the difference between OAuth and OAuth2?

OAuth 2.0 is much easier to use but much more challenging to develop securely. much more adaptable OAuth 1.0 only addressed web workflows; OAuth 2.0 also takes into account clients that aren’t web-based.

How do I validate a username?

A username is considered valid if all the following constraints are satisfied:

  1. The username can have anywhere between six and thirty characters.
  2. Only alphanumeric characters and underscores (_) are permitted in the username.
  3. A lowercase or alphabetic character, such as one from the alphabet, must be the first character of the username.

How do you secure endpoints in Spring boot?

By configuring Spring Security in the application, you accomplish that. Spring Boot automatically secures all HTTP endpoints with “basic” authentication if Spring Security is on the classpath. However, you can alter the security options further. Add Spring Security to the classpath as soon as possible.

What is JWT authentication in Spring boot?

An open Internet standard (RFC 7519) for securely and compactly transmitting trusted information between parties is JSON Web Token, or JWT as it is more commonly known. The claims in the tokens are digitally signed with a private secret or a public key/private key pair and are encoded as JSON objects.

Why is JWT encrypted?

Order for signing and encrypting

JSON Web Tokens (JWT) can be signed and encrypted to guarantee the claims’ confidentiality. Although it is technically possible to create a nested JWT in any order, senders should sign the JWT first and then encrypt the resulting message.

What is difference between bearer token and JWT?

Short response. JWTs are a practical method for encoding and verifying claims. A Bearer token is just a string—possibly random—that is used to authorize transactions.

What is difference between OAuth and bearer token?

In OAuth2, bearer tokens are used for authentication. A bearer token is a value that has been encoded and typically includes the user ID, an authenticated token, and a timestamp. REST APIs are where it is most frequently used. The API will use a bearer token if OAuth2 is supported.

Does Facebook use JWT?

It offers the entry point “/auth/facebook,” which directs users to their FBs and starts the authentication process. Then it obtains the logged-in user’s AccessToken and generates a JWT Token that is returned to the client.

Why is JWT used?

JWT: Why Use It? JWTs are used as a safe method to share information and authenticate users. The issuer typically signs the JWT using a secret or private key. In order to make sure that the token hasn’t been changed after the issuer signed it, the receiver of the JWT will check the signature.

How secure is OAuth token?

OAuth is a very safe protocol. Its strength, as with any security implementation, depends on the strength of its weakest link. The authentication process for implicit grant flows, like your single page web application, takes place between the user and the Identity provider.

Why is OAuth better than basic authentication?

OAuth is the way to go for better online account security because, unlike Basic Auth, it doesn’t reveal your password. OAuth is more of an authorization framework, which explains why. This safeguards your login information.

IT IS IMPORTANT:  What are the 2 types of fall protection used in construction?

Can JWT token be stolen?

Keep in mind that if a JWT (JSON Web Token) is stolen, it could be disastrous for both the victim and the company because there is a high risk of data breach and exploitation.

Should I use JWT for authentication?

In conclusion. Although JWT does eliminate the database lookup, it also adds complexity and security concerns. Either something is secure or it’s not; security is binary. Consequently, it is risky to use JWT for user sessions.

What is the difference between SSO and OAuth?

First off, Single Sign On and OAuth are not the same thing (SSO). Despite some similarities, they are very different from one another. An authorization protocol is OAuth. The phrase “Single Sign-On” (SSO) refers to a situation in which a user uses the same login information to access multiple domains.

Can we use OAuth for authentication?

A delegation protocol that is useful for communicating authorization decisions among a network of web-enabled applications and APIs is defined by the OAuth 2.0 specification. In addition to offering mechanisms for user authentication, OAuth is used in a wide range of applications.

What is API threat protection?

Behavioral analytics and threat hunting are combined in advanced API threat protection, a SaaS-based approach to API security, to: Discover all APIs used by an organization, including shadow or zombie APIs.

How use JWT token secure API?

In a nutshell, JWT works like this:

  1. The sign-in request is sent by the user/client app.
  2. Following verification, the API will generate a JSON Web Token and sign it with a secret key (more on this in a moment).
  3. The client application will then receive that token from the API.

Is a refresh token a JWT?

The refresh token is used to generate new JWT access tokens when existing ones expire, and the JWT is used to access secure routes on the API.

What is REST API endpoint example?

In order to use a RESTful API, an application must define one or more URL endpoints with the following information: https://mydomain/user/123?format=json, for instance. For instance, a GET request to /user/ returns a list of all users who have registered on the system.

How do you validate a regular expression?

To match and validate the text that users enter in the cfinput and cftextinput tags, you can use regular expressions. The match pattern is defined by the combination of common and special characters. Only when the user’s input matches the pattern does the validation succeed.
