Security
JSON Web Tokens (JWT) are used everywhere (even places they shouldn’t be). This post will cover the basics of what you need to know about JWT and the related specifications in the Javascript Object Signing and Encryption (JOSE) family.
The topic of validating an OAuth 2.0 access tokens comes up frequently on this blog. Often we talk about how to validate JSON Web Token (JWT) based access tokens; however, this is NOT part of the OAuth 2.0 specification. JWTs are so commonly used that Spring Security supported them before adding support for remotely validating tokens (which is part of the OAuth 2.0 specification.)
PASETO is a new security token format designed to be easy to use and free from the issues inherent with JSON Web Token (JWT) related specifications. Platform Agnostic SEcurity TOkens (PASETO) is a draft RFC spec created by Scott Arciszewski. PASETO reduces the scope of the JavaScript Object Signing and Encryption (JOSE) family of specs (which JWT is a part of), while still providing the functions that secure applications need.
Apache Shiro is a Java security framework that can perform authentication, authorization, session management, along with a host of other features for building secure applications. In this tutorial, you will build a simple Java REST application using JAX-RS. JAX-RS, like many Java APIs, is a set of interfaces, and you will need to pick an implementation
Many of us are not familiar with vulnerability reporting and how it is different from reporting a regular bug. Frequently, I’ve seen people report vulnerabilities or potential security issues incorrectly. A public bug tracker or Stack Overflow is NOT the right tool; developers need to handle vulnerabilities differently and should not disclose them until the project/vendor fixes them.
