GIAC GSLC Question Answer

Your IDS discovers that an intruder has gained access to your system. You immediately stop that access, change passwords for administrative accounts, and secure your network. You discover an odd account (not administrative) that has permission to remotely access the network. What is this most likely?

An example of IP spoofing.

A backdoor the intruder created so that he can re-enter the network.

A normal account you simply did not notice before. Large networks have a number of accounts; it is hard to track them all.

An example of privilege escalation.
