What kind of attacks does Google Cloud Armor mainly protect against?

Google Cloud Armor is specifically designed to protect applications and services hosted on Google Cloud from Distributed Denial of Service (DDoS) attacks and similar threats. It achieves this by using a comprehensive set of security features, including traffic filtering and rate limiting, which helps to mitigate the impact of volumetric, protocol, and application-layer attacks.

DDoS attacks aim to overwhelm a service with traffic, making it unavailable to legitimate users. Google Cloud Armor provides a robust defense by allowing users to define security policies that automatically inspect incoming traffic based on predefined rules. This proactive approach helps in identifying malicious traffic patterns before they can affect the service's availability.

Other types of attacks, such as SQL injection, phishing, and data breaches, are not the primary focus of Google Cloud Armor. While it contributes to a broader security strategy that may involve other tools for web application security and identity management, the core functionality of Google Cloud Armor is centered around protecting against DDoS and traffic overload scenarios.
