Firewalls Questions
The role of firewalls in securing voice over IP (VoIP) communications is to monitor and control the incoming and outgoing network traffic to protect the VoIP system from unauthorized access, malicious attacks, and potential security breaches. Firewalls act as a barrier between the internal network and the external network, inspecting the data packets and applying security rules to allow or block specific types of traffic. They can also provide features such as intrusion detection and prevention, network address translation (NAT), and virtual private network (VPN) capabilities to enhance the security of VoIP communications.
