How to Harden Falco
Allowlists
Create allowlists to specify trusted system calls, network activity, and file access. This helps reduce false positives and improve the accuracy of threat detection.
Key Rotation
Regularly rotate encryption keys to maintain the confidentiality and integrity of sensitive data.
Hardening
Implement additional security measures, such as:
- Configuring Falco to run as a non-root user
- Enabling SELinux or AppArmor
- Limiting network access to trusted sources
Malware Response Playbook with Rollback and Dedupe Storage
Overview
This playbook provides a step-by-step guide for responding to malware incidents using Falco, rollback, and dedupe storage.
Step 1: Detection and Alerting
Falco detects and alerts on potential malware activity. Respond promptly to these alerts to minimize the attack surface.
Step 2: Containment and Eradication
Use Falco to contain the malware and prevent further propagation. Eradicate the malware by deleting or quarantining affected files and processes.
Step 3: Rollback and Recovery
Use rollback and dedupe storage to restore affected systems and data to a known good state.
