Building an Internal TLS and SSL Certificate Monitoring Agent: From Concept to Deployment

Can you monitor your internal SSL certificates? This was a question we frequently heard from our clients. Many organizations keep their services (web, database, etc.) inaccessible on the public internet, for security, compliance, cost, and other reasons. At TrackSSL, we initially offered public SSL/TLS certificate monitoring, but we often received requests from customers for private SSL certificate monitoring. Thus, we needed to find a way to monitor certificates used on servers that are not typically accessible from the Internet.

In this article, we share our journey of developing a remote certificate monitoring service using an agent that runs on an organization's private network. We share the requirements we defined, the architecture we selected, and the solution we implemented.

Using Machine Learning for Log Analysis and Anomaly Detection: A Practical Approach to Finding the Root Cause

There are many articles on applying machine learning for log analysis. However, most of them are dated, academic in nature, or don’t focus on practical outcomes. On DZone, the last time an article covering how ML can be used for log analysis was published 5 years ago.

In this article, we want to share our real-life experience on using ML/AI for log analysis and anomaly detection with the specific purpose of automatically uncovering the root cause of software issues.

7 Best Log Management Tools for Kubernetes [2020]

You may be wondering why you should bother with Kubernetes' log management tools?

Kubernetes dominates the container orchestration market and is often used to host microservices. Each instance of a microservice generates large numbers of log events that can quickly become difficult to manage.  But worse, when something goes wrong, finding the root cause can be tough due to the complex interactions between services and the near-infinite number of possible failure modes. This potential for trouble has fueled the popularity of log management tools for Kubernetes.
