What is the minimum size of the data payload in an Ethernet frame?

Answer the following statements true (T) or false (F)

1. Buffer overflow attacks are one of the most common attacks seen. 2. Buffer overflow exploits are no longer a major source of concern to security practitioners. 3. A buffer overflow error is not likely to lead to eventual program termination. 4. To exploit any type of buffer overflow the attacker needs to identify a buffer overflow vulnerability in some program that can be triggered using externally sourced data under the attackers control. 5. At the basic machine level, all of the data manipulated by machine instructions executed by the computer processor are stored in either the processor’s registers or in memory.

A characteristic rule is a rule of the form {p} ?? {q1, q2,...,qn}, where the rule antecedent contains only a single item. An itemset of size k can produce up to k characteristic rules. Let ? be the minimum confidence of all characteristic rules generated from a given itemset: Is ? monotone, anti-monotone, or non-monotone?

For each of the following measures, determine whether it is monotone, anti-

monotone, or non-monotone (i.e., neither monotone nor anti-monotone).
