How to Check if a Java Project Depends on A Vulnerable Version of Log4j
The team at FullHunt provided an open-source tool called log4j-scan, an automated and extensive scanner for finding vulnerable Log4j hosts. It allows teams to scan their infrastructure but also test for WAF (Web Application Firewall) bypasses that can result in code execution. The tool has several options but in short, you pass to the tool the URL to scan and you get a report on the vulnerabilities found. For example:

Securing Remix Apps with Keycloak
In this article we'll be using Keycloak to quickly augment an application with user management and SSO. We will demonstrate the integration by securing a page for logged-in users. This quickly provides a jump-off point to more complex integrations.

Simplifying Keycloak Configuration with Terraform and Terragrunt
Keycloak, an open-source identity and access management solution, provides robust authentication and authorization services for modern applications. However, configuring Keycloak instances manually can be tedious and error-prone. In this blog post, we'll explore how to simplify Keycloak configuration using Terraform and Terragrunt, enabling infrastructure as code (IaC) practices for managing Keycloak realms, clients, users, and more.

Securing Vue Apps with Keycloak
In this article we'll be using Keycloak to secure a Vue.js Web application. We're going to leverage oidc-client-ts to integrate OIDC authentication with the Vue app. The oidc-client-ts package is a well-maintained and used library. It provides a lot of utilities for building out a fully production app.

What Is OIDC?
> Don't outsource either your authentication or authorization. Run it in-house.
This is hard to do, though. I hope people here will drop a lot of combinations that work for them!
Personally, for a small/medium scale project, I went with:
Keycloak: https://www.keycloak.org/
It supports various backing RDBMSes (like PostgreSQL, MariaDB/MySQL and others), allows both users that you persist in your own DB, as well as various external sources, like social login across various platforms, is an absolute pain to configure and sometimes acts in stupid ways behind a reverse proxy, but has most of the features that you might ever want, which sadly comes coupled with some complexity and an enterprise feeling.
I quite like that it offers the login/registration views that you need with redirects, as well as user management, storing roles/permissions and other custom attributes. It's on par with what you'd expect and should serve you nicely.
mod_auth_openidc: https://github.com/OpenIDC/mod_auth_openidc
This one's a certified OpenID Connect Relying Party implementation for... Apache2/httpd.
Some might worry about the performance and there are other options out there (like a module for OpenResty, which is built on top of Nginx), but when coupled with mod_md Apache makes for a great reverse proxy/ingress for my personal needs.
The benefit here is that I don't need 10 different implementations for each service/back end language that's used, I can outsource the heavy lifting to mod_auth_openidc (protected paths, needed roles/permissions, redirect URLs, token renewal and other things) and just read a few trusted headers behind the reverse proxy if further checks are needed, which is easy in all technologies.
That said, the configuration there is also hard and annoying to do, as is working with OpenID Connect in general, even though you can kind of understand why that complexity is inherent. Here's a link with some certified implementations, by the way: https://openid.net/developers/certified-openid-connect-imple...
