To begin with Spring Security, add the necessary dependency to your Spring Boot project's build file (Maven or Gradle):
Upon adding the dependency, Spring Boot will automatically configure Spring Security with its default settings.

Spring Security supports various authentication mechanisms, such as in-memory, JDBC, LDAP, and OAuth2. To configure authentication, create a Java class extending 𝚆𝚎𝚋𝚂𝚎𝚌𝚞𝚛𝚒𝚝𝚢𝙲𝚘𝚗𝚏𝚒𝚐𝚞𝚛𝚎𝚛𝙰𝚍𝚊𝚙𝚝𝚎𝚛 and override the 𝘤𝘰𝘯𝘧𝘪𝘨𝘶𝘳𝘦(𝘈𝘶𝘵𝘩𝘦𝘯𝘵𝘪𝘤𝘢𝘵𝘪𝘰𝘯𝘔𝘢𝘯𝘢𝘨𝘦𝘳𝘉𝘶𝘪𝘭𝘥𝘦𝘳 𝘢𝘶𝘵𝘩) method.
For instance, to set up in-memory authentication:

To set up role-based authorization, override the 𝘤𝘰𝘯𝘧𝘪𝘨𝘶𝘳𝘦(𝘏𝘵𝘵𝘱𝘚𝘦𝘤𝘶𝘳𝘪𝘵𝘺 𝘩𝘵𝘵𝘱) method in your 𝚆𝚎𝚋𝚂𝚎𝚌𝚞𝚛𝚒𝚝𝚢𝙲𝚘𝚗𝚏𝚒𝚐𝚞𝚛𝚎𝚛𝙰𝚍𝚊𝚙𝚝𝚎𝚛 class. Define access rules for specific endpoints based on user roles:

To secure RESTful APIs, use the same 𝘤𝘰𝘯𝘧𝘪𝘨𝘶𝘳𝘦(𝘏𝘵𝘵𝘱𝘚𝘦𝘤𝘶𝘳𝘪𝘵𝘺 𝘩𝘵𝘵𝘱) method, configuring the authentication mechanism accordingly, such as using JWT or 𝗢𝗔𝘂𝘁𝗵𝟮. Additionally, set Spring Security to use stateless session management and disable CSRF protection:

Spring Security offers several additional configurations to enhance your application's security:
- 𝙀𝙣𝙖𝙗𝙡𝙚 𝙃𝙏𝙏𝙋𝙎: Configure an SSL certificate to ensure secure communication.
- 𝘾𝙤𝙣𝙛𝙞𝙜𝙪𝙧𝙚 𝘾𝙊𝙍𝙎 𝙖𝙣𝙙 𝘾𝙎𝙍𝙁 𝙥𝙧𝙤𝙩𝙚𝙘𝙩𝙞𝙤𝙣: Handle cross-origin requests and protect against cross-site request forgery.
- 𝙇𝙞𝙢𝙞𝙩 𝙡𝙤𝙜𝙞𝙣 𝙖𝙩𝙩𝙚𝙢𝙥𝙩𝙨: Prevent brute force attacks by limiting the number of login attempts.
- 𝙄𝙢𝙥𝙡𝙚𝙢𝙚𝙣𝙩 𝙨𝙩𝙧𝙤𝙣𝙜 𝙥𝙖𝙨𝙨𝙬𝙤𝙧𝙙 𝙝𝙖𝙨𝙝𝙞𝙣𝙜: Use strong password encoders like 𝘉𝘊𝘳𝘺𝘱𝘵𝘗𝘢𝘴𝘴𝘸𝘰𝘳𝘥𝘌𝘯𝘤𝘰𝘥𝘦𝘳 for secure password storage.
- 𝙐𝙩𝙞𝙡𝙞𝙯𝙚 𝘾𝙤𝙣𝙩𝙚𝙣𝙩 𝙎𝙚𝙘𝙪𝙧𝙞𝙩𝙮 𝙋𝙤𝙡𝙞𝙘𝙮 (𝘾𝙎𝙋) 𝙝𝙚𝙖𝙙𝙚𝙧𝙨: Mitigate cross-site scripting (XSS) and other code injection attacks.
- 𝘾𝙤𝙣𝙛𝙞𝙜𝙪𝙧𝙚 𝙨𝙚𝙨𝙨𝙞𝙤𝙣 𝙩𝙞𝙢𝙚𝙤𝙪𝙩𝙨: Set automatic session invalidation after a specified period of inactivity.
By following these guidelines, you can significantly enhance the security of your Spring Boot applications, ensuring they are well-protected against various threats.
