Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

screened host
false positive
22. Attempt to block service or reduce activity by overloading the victim machine with ping requests

HIDS
website spoofing
24. IP spoofing attack where the attacker can monitor packets and participate in bidirectional communication

promiscuous
informed
25. An attack where an attacker captures sensitive information and sends it again later in an attempt to replicate the transaction

spoofing
replay
26. IDS that relies on usage patterns and baseline operation - can ID new vulnerability - high rate of false alarms
