# Performing Cloud Native Forensics with Falco ## When to Use - When conducting security assessments that involve performing cloud native forensics with falco - When following incident response procedures for related security events - When performing scheduled security testing or auditing activities - When validating security controls through hands-on testing ## Prerequisites - Familiarity with cloud security concepts and tools - Access to a test or lab environment for safe execution - Python 3.8+ with required dependencies installed - Appropriate authorization for any testing activities ## Instructions Deploy and manage Falco rules for runtime security detection in containerized environments. Parse Falco alerts for incident response. ```yaml # Custom Falco rule for detecting shell in container - rule: Shell Spawned in Container desc: Detect shell process started in a container condition: > spawned_process and container and proc.name in (bash, sh, zsh, dash, csh) and not proc.pname in (docker-entrypo, supervisord) output: > Shell spawned in container (user=%user.name command=%proc.cmdline container=%container.name image=%container.image.repository) priority: WARNING tags: [container, shell, mitre_execution] ``` Key detection rules: 1. Shell spawn in non-interactive containers 2. Sensitive file access (/etc/shadow, /etc/passwd) 3. Outbound connections from unexpected containers 4. Privilege escalation via setuid/setgid 5.
