Behavioral analysis for mission-critical applications

May 30, 2025 · 2 min read

When we talk about modern application security, we often think of Identity and Access Management (IAM), which verifies and manages users’ authentication and authorization to access resources, Security Information and Event Management (SIEM), which helps identify trends and patterns at the infrastructure or endpoint level, and log management systems, which collect and store data for future analysis. However, insider threats, data exposure caused by misconfiguration, or account takeover can remain blind spots.

tirreno's primary security approach captures events (including post-auth threats) and their metadata from your application, enriches this data with user context and network intelligence, calculates user activity metrics, and processes it through predefined rules to detect anomalies. Additionally, this approach creates value as an immutable source of truth for forensic analysis, as the tirreno dashboard provides tools to navigate through all user events and connected identities.

As an example of a mission-critical application, we take the OpenC3 COSMOS application, an open-source command & control system. After a small modification that captures and sends user data to the tirreno sensor, we are able to see what users are doing inside OpenC3 and set up risk behaviors that can block further access in real-time or send a notification for manual review. This way, tirreno acts as a security layer to track user actions, prevent account takeovers, detect insider threats, and identify unusual access patterns inside your application.

It’s not a question of if your organization will be breached... it’s how long will it take to discover it. For a detailed tutorial on setting up tirreno with OpenC3, see this step-by-step guide.
