Azure Udp Ports Unrestricted Access
Description
Detects Azure Network Security Group rules that allow unrestricted UDP access from any source IP address (0.0.0.0/0 or *). Such configurations can expose cloud resources to UDP-based attacks, DoS attacks, and unauthorized access from the internet.
Detection Strategy
• Identifies security rules in Azure Network Security Groups that allow UDP protocol access
• Checks if the source address prefix or prefixes in the rule are set to allow access from any IP (0.0.0.0/0, *, Internet, or any)
• Reports a vulnerability if both conditions are met: UDP protocol is allowed AND source is unrestricted
