This is the fourth lab in my defensive security series. The first three built a WAF, an outbound-only tunnel and a Zero Trust access layer by hand in the Cloudflare dashboard. Lab #4 rebuilds the same architecture as code with Terraform and adds a security pipeline on GitHub Actions,
1. The Technical Problem: The Vulnerability of Management Interfaces Exposing administrative interfaces (such as /admin, monitoring dashboards, or internal tools) directly to the public Internet is one of the most critical attack vectors in web infrastructure. Traditional perimeter defenses suffer from major structural flaws: 1. Brute-Force and Credential Stuffing
One of the most critical and frequently overlooked vulnerabilities in perimeter security architectures is the WAF Bypass via Direct Origin Access. When deploying a Web Application Firewall (WAF) at the edge, organizations often assume all incoming web traffic is thoroughly inspected before reaching their applications. However, if the origin server
How analyzing HTTP/2 Client Hints anomalies provides enterprise-grade bot detection on standard Cloudflare plans. 1. The Vulnerability of Legacy Layer 7 Rules In perimeter security, a common initial defensive measure against automated tools like curl, python-requests, or custom scrapers is matching the User-Agent header. A basic
Introduction Modern application security starts at the edge—long before a request ever reaches an origin server. As threat actors automate reconnaissance, brute-force attempts, and Layer 7 DDoS attacks, security operations teams must rely on perimeter controls to inspect, filter, and mitigate malicious traffic at scale. To gain hands-
