What aspect does the Cloud Firewall primarily focus on?

The Cloud Firewall primarily focuses on network traffic management and filtering. Its main role is to monitor and control incoming and outgoing network traffic based on predetermined security rules. This involves establishing a barrier between a trusted internal network and untrusted external networks, such as the internet.

By filtering network traffic, the Cloud Firewall can protect cloud resources from malicious attacks, unauthorized access, and other security threats. It helps to manage and control data flows, ensuring that only legitimate traffic is allowed through while blocking potentially harmful connections. This feature is critical for maintaining the security and integrity of cloud environments, as it acts as a first line of defense against various types of network-based threats.

Other options, while important in the broader domain of security, do not align with the primary function of a Cloud Firewall. Application-level security testing focuses on software vulnerabilities, data encryption pertains to protecting data at rest or in transit, and user authentication methods are related to verifying user identities.
