Building a Self-Hosted SIEM for Monesize Infrastructure
As Monesize's infrastructure keeps growing, security monitoring had to evolve beyond checking individual servers, reviewing application logs and responding to vulnerabilities when they surface. A production environment generates too much security information for that approach to remain practical. System logs, application events, package inventories, authentication activity and network traffic all contain useful signals, but those signals become much more valuable when they can be collected centrally and investigated in context. That led us to build a self-hosted Security Information and Event Management system, or SIEM, for Monesize. The objective was not simply to install a security dashboard. We wanted a central security monitoring layer that could collect telemetry from our workloads, identify vulnerabilities in installed software, inspect network activity, generate security alerts and give us a single place from which to investigate what was happening across the environment.
