How to Secure Prometheus with HTTPS and Authentication Prometheus is a powerful monitoring tool, but by default, it does not include built-in authentication or transport layer security (TLS). This means anyone with network access can read your metrics, and if data is transmitted without encryption, it can be intercepted by attackers. To secure your Prometheus instance, you must configure both basic authentication and HTTPS . Here's an updated step-by-step guide to help you. 1. Why Secure Prometheus? Prometheus is often used to monitor critical infrastructure, making it a valuable target for attackers. By default, anyone can access your Prometheus dashboard and view sensitive metrics if authentication and encryption are not configured. Without TLS encryption, even if authentication is enabled, the credentials and data can be intercepted over the network. To ensure a minimum level of security, you must configure both HTTPS and authentication . These configurations: Protect your met...

Introduction to Prometheus: Simplifying System Monitoring Prometheus is a powerful open-source tool for monitoring and alerting systems. Created in 2012 at SoundCloud, it has been widely adopted by companies worldwide and boasts an active community of developers and users. In 2016, Prometheus became part of the Cloud Native Computing Foundation , alongside Kubernetes. What is Prometheus? Prometheus collects data as time series , meaning numerical metrics are stored with timestamps. For example, a web server could track request times or the number of active connections. These metrics can include labels (key-value pairs) to add context. Example : If your web application is running slow, Prometheus can provide insights. For instance, it might reveal a spike in request numbers, helping you identify the issue and add resources to handle the load. Key Features Multi-dimensional data model : Metrics are identified by name and key-value pairs. PromQL : A powerful query language for analyzing ...
