Security Automation Tools

SOAR platforms, orchestration tools, scripting, and automation frameworks.

Overview

Automation tools accelerate security operations.

Tool Categories

Python Automation

# IOC enrichment script
import requests

def enrich_ip(ip):
    # VirusTotal
    vt_url = f"https://www.virustotal.com/api/v3/ip_addresses/{ip}"
    vt_result = requests.get(vt_url, headers={"x-apikey": VT_API_KEY}).json()
    
    # AbuseIPDB
    abuse_url = f"https://api.abuseipdb.com/api/v2/check?ipAddress={ip}"
    abuse_result = requests.get(abuse_url, headers={"Key": ABUSE_API_KEY}).json()
    
    return {
        "ip": ip,
        "vt_score": vt_result["data"]["attributes"]["last_analysis_stats"]["malicious"],
        "abuse_score": abuse_result["data"]["abuseConfidenceScore"]
    }

Splunk Automation

# Splunk alert action
import splunk

def block_ip(ip_address):
    service = splunk.connect(port=8089)
    
    # Add to blocklist
    service.saved_searches.create(
        name="blocked_ips",
        search=f"index=firewall | search src_ip={ip_address}"
    )
    
    # Update firewall
    requests.post(
        "https://firewall/api/block",
        json={"ip": ip_address},
        headers={"Authorization": f"Bearer {API_KEY}"}
    )

XSOAR Playbook

# Phishing playbook
name: "Phishing Response"
tasks:
  - id: 1
    name: "Get Email Details"
    type: "integration"
    script: "GetEmailById"
    
  - id: 2
    name: "Extract IOCs"
    type: "regular"
    script: "ExtractIOC"
    
  - id: 3
    name: "Check Reputation"
    type: "integration"
    script: "CheckIPReputation"

Best Practices

1. Start small — Automate repetitive tasks
2. Test thoroughly — Validate automation
3. Document — Maintain runbooks
4. Monitor — Track automation success
5. Iterate — Continuous improvement

Practice

Create a Python script to automate IOC enrichment and blocking.
