Security Automation

Automate security operations for scale and efficiency.

Security Pipeline

# .github/workflows/security.yml
name: Security Pipeline

on: [push, pull_request]

jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Secret Scanning
        uses: trufflesecurity/trufflehog@main

        run: |
          checkov -d . --framework terraform

Automated Remediation

# Auto-remediation script
def remediate_public_s3(bucket_name):
    """Remove public access from S3 bucket."""
    s3 = boto3.client('s3')
    s3.put_public_access_block(
        Bucket=bucket_name,
        PublicAccessBlockConfiguration={
            'BlockPublicAcls': True,
            'IgnorePublicAcls': True,
            'BlockPublicPolicy': True,
            'RestrictPublicBuckets': True
        }
    )

SOAR Integration

playbook:
  name: Suspicious Login Response
  trigger: alert.type == "suspicious_login"
  actions:
    - enrich_ip:
        source: threat_intel
    - if_condition: ip.is_malicious
      then:
        - block_ip:
            firewall: cloudflare
        - disable_user:
            duration: 1h
        - notify:
            channel: security
        - create_ticket:
            priority: high

Compliance as Code

# Checkov custom check
from checkov.terraform.checks.resource.base_resource_check import BaseResourceCheck

class S3Encryption(BaseResourceCheck):
    def __init__(self):
        name = "Ensure S3 bucket has encryption enabled"
        id = "CUSTOM_S3_1"
        supported_resources = ['aws_s3_bucket']
        super().__init__(name=name, id=id, ...)
    
    def scan_resource_conf(self, conf):
        if 'server_side_encryption_configuration' in conf:
            return CheckResult.PASSED
        return CheckResult.FAILED

Best Practices

• Start with high-impact automations
• Test in staging first
• Include manual review gates
• Monitor automation effectiveness
• Regular rule updates

Related Skills

• github-actions (github-actions) - CI/CD automation
• policy-as-code (policy-as-code) - Policy enforcement

When to Use

• You need the security workflow covered by this skill (secrets, scanning, network defense, operations, AI security) inside an authorized scope.

Limitations

• Apply guidance only within authorized scope; test destructive steps in non-production first.
• Docs-only import: upstream scripts and templates not bundled.

Example

# Read-only first: inventory before any active step.
which <tool> && <tool> --help | head -n 20
