The architecture of today's networks is highly complex, with scalability, resiliency, and security at its forefront $$ all to combat the evolving cyber threat landscape.

Cyber attackers are constantly changing and advancing their tactics, techniques, and procedures $($TTPs$)$ to bypass controls and identify and exploit vulnerabilities. Unfortunately, a growing challenge for network security administrators is that these vulnerabilities can exist in various areas of the organization's environment, including hardware devices, data, applications, users, etc.

Furthermore, to ensure adequate coverage in the different regions of the environment, network security administrators utilize many network security technologies and applications to identify, protect, detect, respond to$,$ and recover from threats.

For this activity, you will further research some of the different types of network devices and network security concepts an administrator might be responsible for.

Choose five network security technologies from the Secure Network Technologies And Concepts list below. Then, for each, research and answer the following:

What role does this technology or concept play in network security? Explain its impact and importance to a network security administrator and an organization's security apparatus.

How does this technology function? How does it recognize threats $($i$.$e$.,$ heuristics, signature, behavior, data mining, sandbox$)?$ And how can an attacker try to bypass it$?$

Which of the five functions of the NIST Cybersecurity Framework $($identify$,$ protect, detect, respond, recover$)$ does this technology involve? Note that technology may operate in multiple functions depending on its configuration. If that is the case, please explain.

Post your response to share your research on network security technologies with your peers.
