質問 # 666
Henry, head of network security at Gentech, has discovered a general report template that someone has reserved only for the CEO. Since the file has to be editable, viewable, and deletable by everyone, what permission value should he set?
正解：B
解説：
To allow a file to be editable, viewable, and deletable by everyone, Henry needs to set the file permissions to the most permissive value. In Linux and Unix systems, file permissions are represented by three sets of three bits, each set representing permissions for the owner, the group, and others.
The permission value of 777 means:
* The first digit (7) grants read (4), write (2), and execute (1) permissions to the owner.
* The second digit (7) grants read, write, and execute permissions to the group.
* The third digit (7) grants read, write, and execute permissions to others.
Setting the permissions to 777 ensures that everyone (owner, group, and others) can read, write, and execute the file. This aligns with the requirement for the file to be editable, viewable, and deletable by everyone.

An IT company has just been hit with a severe external security breach. To enhance the company's security posture, the network admin has decided to first block all the services and then individually enable only the necessary services. What is such an Internet access policy called?
正解：C
解説：
The Paranoid Policy is a type of Internet access policy that is characterized by initially blocking all services and then selectively enabling only those that are necessary. This approach is often taken as a security measure following a severe external breach, as it allows the network administrator to ensure that only essential and secure services are accessible, minimizing potential vulnerabilities.
質問 # 668
How can organizations obtain information about threats through human intelligence?
正解：C
解説：
Human intelligence (HUMINT) in the context of network defense involves the collection of information from human sources. This can include extracting insights from security blogs, forums, and other platforms where cybersecurity professionals and enthusiasts discuss vulnerabilities, threats, and incidents. By monitoring these discussions, organizations can gain valuable information about emerging threats, techniques used by attackers, and potential security weaknesses that need to be addressed.
References: The role of human intelligence in gathering threat information is highlighted in cybersecurity literature. For example, CrowdStrike discusses the importance of HUMINT in cybersecurity, noting that it involves engaging with threat actors on various platforms to gather information about their activities1. Additionally, the IEEE paper on "Gathering threat intelligence through computer network deception" emphasizes the significance of proactive threat intelligence development by network defenders2.
質問 # 669
Daniel works as a network administrator in an Information Security company. He has just deployed an IDS in his organization's network and wants to calculate the false positive rate for his implementation. Which of the following formulae can he use to so?
正解：C
解説：
The false positive rate is a measure used to evaluate the performance of an IDS (Intrusion Detection System).
It is calculated by dividing the number of false positives (FP) by the sum of false positives and true negatives (TN). The formula is:
False Positive Rate=FP+TNFP
This formula helps in determining how often the IDS incorrectly classifies an event as a threat, which is actually benign. A lower false positive rate indicates a more accurate IDS.
References: This formula and its application are consistent with standard practices in network security and align with the Certified Network Defender (CND) course material. For further details, please refer to the official CND study guide and documents.
