GCP Load Balancer Security

Client's Goal:

The client required the implementation of advanced security measures for a new load balancer in Google Cloud. Key objectives included:

• Enabling rate limiting to prevent abuse and ensure fair usage.
• Implementing country-based IP bans to restrict access from specific regions.
• Leveraging Web Application Firewall (WAF) features to protect against common web-based threats.

My Contribution:

As the lead architect for this project, I designed and deployed a secure HTTPS load balancer in Google Cloud, tailored to meet the client’s requirements. My contributions included:

1. Load Balancer Implementation:
   • Configured a global HTTPS load balancer to distribute traffic efficiently across backend services.
   • Ensured seamless integration with the client’s existing infrastructure.
2. Cloud Armor Policies:
   • Created and applied rate-limiting rules to control traffic flow and mitigate potential DDoS attacks.
   • Implemented geolocation-based IP bans to block traffic from specific countries, enhancing security and compliance.
   • Configured WAF rules to protect against OWASP Top 10 vulnerabilities, such as SQL injection and cross-site scripting (XSS).
3. Documentation and Knowledge Transfer:
   • Documented the entire setup process, including configuration details and best practices, on the client’s internal wiki platform.
   • Provided training sessions to the client’s team to ensure they could manage and maintain the solution independently.

Outcome:

The project was a success, with all security measures implemented effectively and on schedule. The new load balancer, combined with Cloud Armor policies, provided robust protection against web-based threats and ensured compliance with the client’s security policies. The comprehensive documentation and knowledge transfer empowered the client’s team to manage the solution confidently moving forward.
