How do application-layer firewalls work for mobile security?

Application-layer firewalls operate at layer 7 of the OSI model and are designed to monitor and filter traffic based on the application being used. These firewalls focus on the specific protocols and data streams associated with applications, allowing them to provide more granular control and security. They are able to inspect application data to detect and prevent threats, such as unauthorized access, data exfiltration, and malware propagation. By analyzing the behavior and content of applications, application-layer firewalls can detect and block suspicious activity, enhancing the security of mobile devices against application-specific threats.
