For the following questions I would like you to discuss the particulars of each attack scenario and how Kerberos defends against it.

You will need to consider various elements of the attack scenarios. Some attacks can be implemented between multiple Kerberos components. For example, a MITM attack could occur between various components at various times. State your assumptions about how the attack is occurring, then describe how Kerberos defends against it. Good answers will describe both the particulars of the attack and the Kerberos defenses.

1.) A user gains access to a particular workstation and pretends to be another user from that workstation.

2.) An eavesdropper obtains the IP address of an authenticated workstation and reconfigures another workstation to impersonate the authenticated workstation.

3.) An eavesdropper captures messages and attempts a replay attack to access a server or cause damage.

4.) An eavesdropper obtains the IP address of a server and reconfigures another machine to impersonate the server and capture user requests.

5.) An attacker acts as the man in the middle between two computers (e.g. client and the server). The attacker spoofs each computer to think they have connected to the correct computer, when in fact the attacker is intercepting all transmissions. The attacker can then monitor or change any of the data before routing it on to the intended computer.
