Since HIDS focus on the behavior and activities of individual hosts, they are more likely to produce false alarms due to the unpredictable behaviors of users and networks. Users may engage in unusual activities or network behaviors may change, leading to false alarms being triggered by the HIDS. In contrast, Network-based Intrusion Detection Systems (NIDS) monitor network traffic and are less affected by the specific behaviors of individual hosts, making them less prone to false alarms in this context. Anomaly detection and signature recognition are techniques used by both NIDS and HIDS to identify potential intrusions.Rate this question:

You should make at least ___ bit-stream copies of a suspect drive?
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
B. 2Explanation
When conducting forensic analysis on a suspect drive, it is recommended to make at least two bit-stream copies. This is important because it ensures the preservation of the original evidence and allows for multiple copies to be used for different purposes. Having multiple copies also reduces the risk of data loss or corruption during the analysis process. Additionally, it enables multiple investigators or experts to work on different copies simultaneously, increasing efficiency and collaboration.Rate this question:

- A.
ICMP header field
- B.
TCP header field
- C.
IP header field
- D.
UDP header field
Correct Answer
