Description: The GKE (Google Kubernetes Engine) firewall is a network security system that monitors and controls incoming and outgoing network traffic in a cloud-native environment. Its primary function is to protect the applications and services deployed in the environment from unauthorized access and cyberattacks. This firewall allows the establishment of specific rules that determine which traffic is permitted and which is blocked, helping to maintain the integrity and confidentiality of data. Additionally, it integrates with other security and monitoring tools, providing an extra layer of defense. Features of the GKE firewall include the ability to define network policies, traffic segmentation between different services, and the implementation of role-based access controls. Its relevance lies in the growing need to protect cloud applications, where threats are becoming increasingly sophisticated. With the rise of container orchestration platforms like Kubernetes, the GKE firewall becomes an essential tool for ensuring the security of modern infrastructures.
