by falcosecurity
Falco is a cloud native runtime security tool that detects and alerts on abnormal behavior and potential security threats in real-time on Linux systems.
Cloud Native Runtime Security
Primary Use Case
Falco is primarily used by security operations teams and DevOps engineers to monitor Linux hosts and container environments for suspicious activities and intrusions. It provides real-time detection of anomalous behaviors by analyzing system calls and container metadata, helping organizations enhance their runtime security posture and automate threat detection workflows.
- Real-time kernel-level monitoring of syscalls
- Customizable detection rules for abnormal behavior
- Integration with container runtimes and Kubernetes metadata
- Ability to send events to SIEM and data lake systems for off-host analysis
- Modular architecture with core libraries and plugins
- Official, maintained ruleset for various security threats
- Command-line utility (falcoctl) for management
- Helm charts for easy deployment in Kubernetes environments
Installation
- Visit the official Falco website at https://falco.org/ for detailed installation guides.
- Use Helm charts from the falcosecurity/charts repository to deploy Falco in Kubernetes clusters.
- Clone the repository from https://github.com/falcosecurity/falco to build from source if needed.
- Install kernel drivers and dependencies as required by the core libraries (falcosecurity/libs).
- Use falcoctl command-line utility for managing Falco installations and configurations.
Usage
>_ falcoStarts the Falco daemon to monitor system calls and detect suspicious activity in real-time.
>_ falcoctlCommand-line utility to manage and interact with Falco, including configuration and rule management.
- Integrate Falco alerts with SIEM and SOAR platforms to automate incident response workflows.
- Leverage Falco’s Kubernetes metadata integration to enhance container security monitoring in cloud-native environments.
- Customize detection rules to tailor alerts for specific threat models and reduce false positives.
- Use Falco in CI/CD pipelines for continuous runtime security validation before production deployment.
- Combine Falco with threat hunting tools to proactively identify anomalous behaviors and potential breaches.
