With the proliferation of cloud computing, the security of web applications and APIs has never been more critical. The increased business migration to the cloud raises the stakes even higher, making it imperative for businesses to anticipate and defend against the threats nestled within their virtual landscapes. Prominently among these threats are DDoS attacks and the risks from the OWASP Top 10 list.
Google Cloud Armor Enhancements
Packed with new features such as granular rate limiting and the option to create IP-based custom rules, Google Cloud Armor sets the bar high for application and API security. These features heighten DDoS protection, empower developers with flexibility in managing security norms, and enhance the robustness of their web infrastructure.
Reinventing Limitations with Granular Rate Limiting
A game-changing feature that Google Cloud Armor introduced in June 2022, granular rate limiting allows users to control Layer 7 web requests or TCP/SSL connections according to request volume. This feature has undergone further development, onboarding additional rate limit keys and yielding the ability to combine multiple keys for meticulous control over traffic throttle.
Getting the Best of Cloud Armor Rate Limiting
Cloud Armor’s rate limiting features can be enforced by Google Cloud Console or API using the key method. New key methods like HTTP-PATH, REGION-CODE, and SNI were introduced to help organizations effectively limit maximum requests or connections per client. Users can select up to three types, whose collective values will form the actual key upon which the rate limit action is taken.
Forgoing False Positives with Multi-key Rate Limiting Rule
Entrusting the rate limiting rule to a source IP alone could trigger false positives, potentially throttling legitimate traffic. Cloud Armor’s multi-key rate limiting rule serves as an excellent solution to this conundrum, ensuring that genuine traffic flows unrestrained.
Creating Flexibility in WAF Rule Configurations
Additionally, Google has incorporated user-configurable HTTP request and IP-based attributes – including ‘True-Client-IP’ and custom IPs – into its Cloud Armor suite. These augmentations go a long way toward improving flexibility in devising WAF rule configurations.
Scenario-Based Applications of Cloud Armor Features
Consider a typical scenario where Cloud Armor’s security policy evaluates an upstream proxy rather than the actual IPs from distributed clients upstream. The newly introduced attributes offer a resolution by allowing users to define and adjust what examines a client’s actual IP.
This detailed understanding of Google Cloud Armor and its feature set underscores its essential role in managing web application and API security effectively. To further acquaint yourself with these features and configurations, make sure to steer toward and explore the resources, tutorials, or guides Google has made available.
Enhancing web and API security is no longer cumbersome or complex. With Google Cloud Armor, you have a comprehensive solution at your fingertips, just waiting to secure your digital infrastructure. Your move towards a safer virtual environment starts now.
Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.
Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).
This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.
I honestly can't wait to work in many more projects together!
