Understanding the OWASP API Top Ten for 2023 (and How to Protect Your APIs)





  • In today’s interconnected digital landscape, application programming interfaces (APIs) play a critical role in facilitating communication between software applications.
  • However, with this convenience comes the responsibility of ensuring API security to protect against malicious attacks.
  • Let’s delve into key aspects of API security using insights from Open Web Application Security Project (OWASP) API Security Top Ten for 2023.
  • Let’s explore the fundamental concepts of API security and learn how Radware helps protect your APIs against each of those vulnerabilities.
  • This risk occurs when APIs expose endpoints that manage object identifiers, creating a wide attack surface of Object-level Access Control issues. Object-level authorization checks should be considered for every object of a function or endpoint accessed by a specific user.
  • Object-level authorization is an access control mechanism that is usually implemented at the code level to validate that a user can only access the objects they should have permission to access.
  • This risk occurs when authentication mechanisms are implemented incorrectly, allowing attackers to compromise authentication tokens or exploit implementation flaws to assume other users’ identities temporarily or permanently. Compromising a system’s ability to identify the client/user compromises API security overall.
