What does Covert Channel mean?
attack that allows the communication of information by transferring objects through existing information channels or networks using the structure of the existing medium to convey the data in small parts.
is a DOS attack
Is a SQL Injection Attack
is a buffer overflow attack
Perhaps the question is good but the answering options are not. The correct answer looks read "with existing channel" which sort of assumes that the channel was valid/intended. A covert channel is one that is created maliciously or so I thought. This is a poorly worded question.
