9. Hybrid firewalls combine the elements of other types of firewalls that is, the elements of packet filtering and proxy services or packet filtering and circuit gateways (Ch6 Page 50). 10. UTM is a hybrid built with capabilities of modern networking equipment. UTM systems increasing memory capacity and processor capability and reduce the complexity associated with deploying, configuring, and integrating multiple networking devices. They can even dive deep into protocol layers. A disadvantage of UTM systems is the creation of a single point of failure if the device has technical problems (Ch6 Page 52). 11. A commercial-grade firewall appliance is completely independent from client computers and it runs as software on client computers, which allows and prevents different kind of traffic from coming and going through a network connection. The difference is the load of processing incoming and outgoing traffic is now dealt with by client computers (Ch6 Page 72). 12. They usually are not a target of an attack like a small home or business. This causes protection by creating a local NAT and stops most known intrusions or connections internally (Ch6 Page 60). 13. Residential firewalls/SOHO include packet filtering, port filtering, and simple intrusion detection systems, and restrict access to specific MAC addresses (Ch6 Page 54). 14. Screened host use packet filtering and a separate dedicated firewall versus a screened subnet firewall architecture utilizing a DMZ as a dedicated port between the device and a single host. Routing unauthorized network traffic, as all requests that occur within the network do not respond to outside IP addresses are made a lot easier (Ch6 Page 66).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
