Term 318
Windows Defender Firewall is a built-in security feature in Microsoft Windows that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
Term 319
Workload Identity Federation lets a non-human software workload (like an app or server) securely prove its identity to a cloud provider using a token from an external identity provider, without needing long-term secrets.
