Choose three network$-$focused attacks listed in the text, and answer the following questions for each:

What vulnerabilities in the network must exist for the attack to be successful?

Are the vulnerabilities purely technical$/$configuration related, or do clients$/$users of the network contribute to the potential vulnerability in the way they use the network?

Which NIST$800-53$ controls, if properly implemented, could mitigate the attack?

How do physical security and network security relate to each other? Can a well$-$implemented physical security plan mitigate vulnerabilities in the network, and can a hardened network mitigate a poorly implemented physical security plan?
