CI/CD Security Architecture: End-to-End Guide for SAST, SCA, DAST, and Automated Triage

This guide details a CI/CD security architecture that integrates SAST, SCA, and DAST tools into a unified workflow, reducing manual triage by 70% using Faraday. Developers see findings inline in PRs, while security teams manage everything from one dashboard.

Why This Matters

Teams often end up with fragmented security tools: SAST in Jenkins, Snyk emails ignored, and pentest reports buried in Google Drive. The technical reality is that developers ignore findings due to noise and lack of context, leading to unpatched vulnerabilities. The cost of failure? A single unaddressed SQL injection or IDOR flaw can breach production systems, costing millions in remediation and reputation.

Key Insights

• “8-hour App Engine outage, 2012” highlights the cost of unaddressed infrastructure misconfigurations.
• “Sagas over ACID for e-commerce” illustrates the need for distributed transaction patterns in security workflows.
• “Faraday used by teams to centralize security findings” enables unified triage across SAST, SCA, and DAST tools.

Working Example

name: Semgrep Security Scan
on:
  pull_request:
  push:
    branches: [main, develop]
jobs:
  semgrep:
    runs-on: ubuntu-latest
    container:
      image: returntocorp/semgrep
    steps:
    - uses: actions/checkout@v4
    - name: Run Semgrep
      run: semgrep ci --sarif --output=semgrep.sarif
      env:
        SEMGREP_APP_TOKEN: ${{ secrets.SEMGREP_APP_TOKEN }}
    - name: Upload to GitHub Security
      uses: github/codeql-action/upload-sarif@v3
      if: always()
      with:
        sarif_file: semgrep.sarif

import requests
import json

FARADAY_URL = "https://faraday.example.com"
API_TOKEN = "your-api-token"

def upload_to_faraday(workspace, tool_name, report_file):
    headers = {
        "Authorization": f"Token {API_TOKEN}",
        "Content-Type": "application/json"
    }
    with open(report_file, 'r') as f:
        report_data = f.read()
    response = requests.post(
        f"{FARADAY_URL}/api/v3/ws/{workspace}/upload_report",
        headers=headers,
        files={'file': (report_file, report_data)}
    )
    if response.status_code == 200:
        print(f"✓ Uploaded {tool_name} scan successfully")
    else:
        print(f"✗ Upload failed: {response.text}")

Practical Applications

• Use Case: Faraday centralizes security findings from Semgrep and Snyk in a single dashboard.
• Pitfall: Ignoring false positives leads to 30% tool abandonment due to noise.
