# Standards and References - Container Escape Detection with Falco
|
|
|
|
## Industry Standards
|
|
|
|
### NIST SP 800-190: Application Container Security Guide
|
|
- Section 4.3: Container Runtime - Monitor containers for anomalous behavior at runtime
|
|
- Section 5.4: Container Runtime Security - Implement runtime monitoring and alerting
|
|
- Recommends syscall-level monitoring for escape detection
|
|
|
|
### CIS Kubernetes Benchmark v1.8
|
|
- 5.7.1: Create administrative boundaries between resources using namespaces
|
|
- 5.7.2: Ensure that the seccomp profile is set to docker/default
|
|
- 5.7.3: Apply Security Context to pods and containers
|
|
- 5.7.4: The default namespace should not be used
|
|
|
|
### MITRE ATT&CK for Containers
|
|
|
|
| Technique ID | Name | Falco Detection |
|
|
|-------------|------|-----------------|
|
|
| T1611 | Escape to Host | nsenter, mount, chroot detection |
|
|
| T1610 | Deploy Container | Privileged container launch detection |
|
|
| T1003 | OS Credential Dumping | /etc/shadow access from container |
|
|
| T1005 | Data from Local System | Sensitive file read detection |
|
|
| T1059 | Command and Scripting Interpreter | Shell spawn in container |
|
|
| T1068 | Exploitation for Privilege Escalation | Kernel exploit indicators |
|
|
|
|
### NSA/CISA Kubernetes Hardening Guide v1.2
|
|
- Section 5: Audit Logging and Threat Detection
|
|
- Enable runtime security monitoring
|
|
- Detect anomalous container behavior in real-time
|
|
- Monitor for privilege escalation attempts
|
|
|

## Falco Rule Maturity Levels
|
|
|
|
| Level | Description | Count |
|
|
|-------|-------------|-------|
|
|
| maturity_stable | Production-ready, low false positives | 25 rules |
|
|
| maturity_incubating | Proven useful, may need tuning | ~30 rules |
|
|
| maturity_sandbox | Experimental, high false positive rate | ~38 rules |
|
|
| maturity_deprecated | Scheduled for removal | Variable |
|
|
|
|
## Known Container Escape CVEs
|
|
|
|
| CVE | Description | Falco Rule |
|
|
|-----|-------------|------------|
|
|
| CVE-2024-21626 | runc process.cwd container breakout | Detect use of /proc/self/fd to access host |
|
|
| CVE-2022-0492 | cgroup v1 release_agent escape | Write to Cgroup Release Agent |
|
|

|
|
| CVE-2019-5736 | runc overwrite host binary | Detect writes to /proc/self/exe |
|
|
|
|
## Compliance Mappings
|
|
|
|
### PCI DSS v4.0
|
|
- Requirement 10.6.1: Review logs for anomalies at least daily
|
|
- Requirement 11.5: Deploy change-detection mechanisms
|
|
|
|
### SOC 2 Type II
|
|
- CC7.2: Monitor system components for anomalies
|
|
- CC7.3: Evaluate security events to determine impact
