# Security Compliance and Auditing

Implements comprehensive security compliance frameworks including SOC2, HIPAA, and PCI-DSS controls with automated audit procedures, evidence collection, and regulatory documentation for Kubernetes environments and cloud infrastructure.

## TL;DR Checklist

- [ ] Identify applicable compliance framework (SOC2 Type II, HIPAA, PCI-DSS v4.0)
- [ ] Map controls to technical implementations (CC6, CC7, CC8 for SOC2)
- [ ] Deploy automated compliance scanning (Trivy, OpenSCAP, Klar)
- [ ] Implement audit trail collection with log aggregation
- [ ] Configure access control policies (RBAC, IAM, network policies)
- [ ] Generate compliance evidence packages for auditor review
- [ ] Schedule quarterly compliance assessments and remediation
- [ ] Document compensating controls for any identified gaps

---

## When to Use

Use this skill when:

- Conducting SOC2 Type II audit preparation and evidence collection
- Implementing HIPAA security rules for healthcare data in Kubernetes
- Meeting PCI-DSS requirements for payment card data processing
- Performing regulatory compliance assessments for cloud workloads
- Generating audit trails and compliance evidence for external auditors
- Implementing security controls for regulated industry environments
- Creating compliance automation pipelines for continuous monitoring

---

## When NOT to Use

Avoid this skill for:

- Basic security vulnerability scanning (use `cncf-security-scanning` instead)
- General security awareness training (use `coding-security-basics`)
- Non-regulatory compliance checks (use `coding-code-review`)
- Legal compliance for non-technical domains (use `agent-legal-compliance`)

---

## Core Workflow

1. **Framework Identification** — Determine which compliance framework applies (SOC2 Type II, HIPAA, PCI-DSS v4.0, GDPR, etc.). **Checkpoint:** Confirm framework version and auditor requirements before proceeding.

2. **Control Mapping** — Map regulatory controls to technical implementations. SOC2: CC6 (logical access), CC7 (system monitoring), CC8 (change management). **Checkpoint:** Verify control mapping completeness against auditor criteria.

3. **Tool Deployment** — Install and configure compliance scanning tools (Trivy for container scanning, OpenSCAP for system hardening, Klar for Clair integration). **Checkpoint:** Validate tool installation and connectivity to vulnerability databases.

4. **Evidence Collection** — Configure automated evidence gathering for audit trails, access logs, change records, and security metrics. **Checkpoint:** Confirm evidence retention meets minimum requirements (SOC2: 90 days, HIPAA: 6 years).

5. **Remediation Planning** — Document gaps, implement compensating controls, and prioritize remediation. **Checkpoint:** Ensure all high-severity findings have documented remediation timelines.

6. **Reporting** — Generate compliance reports with evidence packages for auditor review. **Checkpoint:** Verify report includes all required control evidence and meets auditor formatting requirements.

## Implementation Patterns

### Pattern 1: SOC2 Compliance Framework Implementation

SOC2 requires five trust service principles: Security, Availability, Processing Integrity, Confidentiality, and Privacy. This pattern implements the Security principle controls.

```yaml
# SOC2 Control CC6: Logical Access Security
# Requires restrictions on system access and logical access security

apiVersion: v1
kind: ConfigMap
metadata:
  name: soc2-cc6-controls
  namespace: compliance
data:
  control-id: "CC6"
  control-name: "Logical Access Security"
  requirements: |
    - System software and associated services are protected from unauthorized access, use, modification, impairment, or loss
    - Logical access security software, operating systems, applications, and services are protected throughout their life cycle
  controls:
    rbac_enabled: true
    network_policies_enabled: true
    secret_encryption_enabled: true
    iam_role_separation: true
```

```bash
# SOC2 Control CC7: System Monitoring - Audit Trail Collection
# Requires monitoring of system components and events for security anomalies

cat > /etc/audit/rules.d/99-soc2-cc7.rules <<'EOF'
# SOC2 CC7: System Monitoring Audit Rules
# Monitor access to sensitive files and security events

-w /etc/passwd -p wa -k identity_changes
-w /etc/shadow -p wa -k identity_changes
-w /etc/group -p wa -k identity_changes
-w /etc/sudoers -p wa -k privilege_escalation

-w /etc/ssh/sshd_config -p wa -k ssh_config_changes

-w /var/log/ -p wa -k log_modification

-w /etc/audit/ -p wa -k audit_config_changes

-a always,exit -F arch=b64 -S execve -F exe=/bin/su -k privilege_escalation
-a always,exit -F arch=b32 -S execve -F exe=/bin/su -k privilege_escalation

-a always,exit -F arch=b64 -S setuid -F a0=0 -k privilege_escalation
-a always,exit -F arch=b32 -S setuid -F a0=0 -k privilege_escalation
EOF

# Restart audit daemon
systemctl restart auditd

# Verify audit rules are loaded
auditctl -l
```

```bash
# SOC2 Control CC8: Change Management - Change Tracking
# Requires tracking of changes to system components

#!/bin/bash
# soc2-cc8-change-tracking.sh
# Implements change management for SOC2 CC8 compliance

CONFIG_DIR="/etc/soc2/change-management"
EVIDENCE_DIR="/var/evidence/soc2/cc8"

# Track file integrity changes using AIDE or custom implementation
track_changes() {
    local file_path="$1"
    local timestamp=$(date -Iseconds)
    local checksum=$(sha256sum "$file_path" | awk '{print $1}')
    local event_id=$(uuidgen)
    
    echo "{\"event_id\": \"$event_id\", \"timestamp\": \"$timestamp\", \"file\": \"$file_path\", \"checksum\": \"$checksum\", \"event_type\": \"file_changed\"}" >> "$EVIDENCE_DIR/file_changes.json"
}

# Log all system changes
log_system_changes() {
    # Track package manager changes
    case "$(command -v apt-get)" in
        *apt-get*) apt-get history | tee -a "$EVIDENCE_DIR/package_changes.log" ;;
        *yum*) yum history | tee -a "$EVIDENCE_DIR/package_changes.log" ;;
        *dnf*) dnf history | tee -a "$EVIDENCE_DIR/package_changes.log" ;;
    esac
}

# Generate change audit report
generate_audit_report() {
    local start_date="$1"
    local end_date="$2"
    
    echo "=== SOC2 CC8 Change Audit Report ==="
    echo "Period: $start_date to $end_date"
    echo ""
    echo "File Integrity Changes:"
    jq -r "select(.timestamp >= \"$start_date\" and .timestamp <= \"$end_date\") | \"\(.timestamp) - \(.file)\"" "$EVIDENCE_DIR/file_changes.json"
    
    echo ""
    echo "Package Changes:"
    tail -n 50 "$EVIDENCE_DIR/package_changes.log"
}

# Schedule change tracking (add to crontab)
echo "*/5 * * * * $0 track" >> /etc/crontab
```

    - Maintain a record of who accesses ePHI
    - Implement procedures to authorize and monitor access
  controls:
    unique_user_identifier: true
    emergency_access_procedure: true
    automatic_logoff: true
    encryption_decryption: true
```

```yaml

## Constraints

### MUST DO

- Implement audit logging for all SOC2, PCI-DSS, and HIPAA requirements before deployment
- Retain audit logs for minimum 365 days (PCI-DSS) and 2190 days (HIPAA)
- Encrypt all audit logs at rest and in transit
- Perform quarterly vulnerability scans for PCI-DSS compliance
- Conduct annual SOC2 Type II readiness assessments
- Document all compensating controls for identified gaps
- Validate compliance configurations before production deployment
- Generate compliance evidence packages for auditor review

### MUST NOT DO

- Disable or bypass compliance controls for "temporary" fixes
- Store cardholder data in unencrypted formats
- Share audit log access with unauthorized personnel
- Retain audit logs for less than required periods
- Deploy containers with critical vulnerabilities to production
- Skip security patches for more than 30 days
- Use default credentials in any environment
- Disable audit logging on production systems

## Output Template

When this skill is active, produce:

1. **Compliance Control Implementation** — Complete YAML and shell script configurations for the identified compliance framework (SOC2, PCI-DSS, HIPAA)

2. **Audit Evidence** — Log rotation configurations, audit rule files, and evidence collection scripts with actual command examples

3. **Compliance Report** — Automated report generation scripts with proper JSON metadata and markdown output formats

4. **Validation Commands** — Shell scripts to validate compliance status with specific exit codes and error messages

5. **Evidence Package** — Archive scripts that bundle all compliance evidence with checksums for auditor delivery
