While there are numerous authentication mechanisms available, one stands out for its robust security model: Mutual TLS (mTLS). This comprehensive guide will walk you through everything you need to know about mTLS, from basic concepts to implementation details. Introduction to TLS Before diving into mutual TLS, let's first understand what TLS itself is.

It's the successor to Secure Sockets Layer (SSL) and is widely used for securing web browsing, email, messaging, and other data transfers.

I will write a separate blog on why do we need ELK? In this blog, I’ll show you how can we push spring boot application log directly to Elastic search using Logstash which we can analyze on Kibana and If you don’t know how to install ELK on windows 10 then you can refer my previous blog and start Elastic Search and Kibana server. Prerequisite Elastic Search and Kibana running on your machine Basic knowledge of Spring boot application If you don’t want to start your application from scratch then you can download one spring boot application from my GitHub repository as well. I am assuming that the Elastic Search and Kibana server are running on your machine and you have a fair idea of how to start the Logstash server and what is Logstash conf file. So, to push spring boot logs cont...
