A firewall designed to operate at the media access control sublayer of the network’s data link layer is called a ________ firewall.
media access control layer
Media access control layer firewalls make filtering decisions based on the specific host computer’s identity, as represented by its ________ address.
MAC or network interface card (NIC)
Hybrid firewalls combine the elements of other types of firewalls, such as packet filtering, application layer proxy, and media access control layer firewalls. They are also known as ________ firewalls.
UTM
Unified Threat Management (UTM) devices are categorized by their ability to perform the work of an SPI firewall, network intrusion detection and prevention system, content filter, spam filter, and malware scanner and filter. UTM is the first type of ________ firewall.
hybrid
Next Generation Firewall (NextGen or NGFW) is a security appliance that delivers unified threat management capabilities in a single appliance. NextGen firewalls combine traditional firewall functions with other network security functions, such as deep packet inspection, IDPSs, and the ability to decrypt encrypted traffic. NextGen firewalls are the second type of ________ firewall.
hybrid
The configuration that works best for a particular organization depends on three factors: the objectives of the network, the organization’s ability to develop and implement the architectures, and the ________ available for the function.
budget
A single bastion host is a highly secured computer system that is placed outside the organization's network and is designed to withstand attacks from the ________. All traffic from the internet must pass through this host before reaching the internal network.
internet
