GIAC Global Industrial Cyber Security Professional (GICSP) GICSP Prüfungsfragen mit Lösungen (Q77-Q82):

77. Frage
Which of the following is considered an essential step in endpoint hardening?
Response:

Antwort: A


78. Frage
An administrator relaxes the password policy during disaster recovery operations. What is the result of this action?

Antwort: D

Begründung:
Comprehensive and Detailed Explanation From Exact Extract:
Relaxing password policies during disaster recovery often leads to increased risk (C) by weakening authentication controls and potentially allowing unauthorized access.
Recovery Point Objective (RPO) (A) relates to data loss tolerance and is unlikely directly affected by password policies.
Recovery Time Objective (RTO) (B) relates to restoration speed, and while relaxed policies may speed access, this is outweighed by security risk.
Reduced insurance needs (D) is not a direct consequence of relaxed security policies.
GICSP stresses that even during emergencies, security controls should be maintained to prevent additional vulnerabilities.

79. Frage
What does the following command accomplish?
$ chroot /home/jdoe /bin/bash

Antwort: D

Begründung:
The chroot command changes the apparent root directory (/) for the current running process and its children to the specified directory-in this case, /home/jdoe.
This "jails" the shell (bash) into /home/jdoe, limiting file system access to that subtree.
It does not change ownership (A), grant privileges (B or C), but provides a confined environment (sandbox).
GICSP discusses chroot as a containment and security mechanism in ICS system hardening.

80. Frage
How could Wireshark be utilized in an attack against devices at Purdue levels 0 or 1?

Antwort: A

Begründung:
Wireshark is a network protocol analyzer primarily used to capture and analyze network traffic. At Purdue levels 0 or 1 (which include physical devices like sensors, actuators, and controllers communicating over industrial protocols), Wireshark can be used to:
Capture serial and fieldbus communications (A), such as Modbus, Profibus, or Ethernet-based protocols, if the network media is accessible. This can reveal sensitive operational data and control commands.
Wireshark cannot capture communications between chips on a board (B) because this is hardware-level, not network traffic.
Detecting open ports by sending packets (C) is a function of port scanning tools, not Wireshark.
Detecting asymmetrical keys or brute forcing crypto keys (D and E) are not capabilities of Wireshark.
The GICSP training highlights the risk of passive monitoring via tools like Wireshark as a means for attackers to gain insight into control system operations.

81. Frage
What approach can an organization use to make sure that high consequence, low probability risks are considered during risk analysis?

Antwort: A

Begründung:
In risk analysis, high consequence, low probability risks-such as catastrophic failures or attacks-require special attention. The best approach to ensure these risks are properly considered is to prioritize risks based on impact (A), focusing on the potential severity of consequences if the event occurs, regardless of its frequency.
Giving frequency or likelihood (B, D) a higher weight can lead to underestimating rare but highly damaging risks.
Mitigation cost (C) is a factor in decision-making but does not ensure identification or prioritization of high- impact risks.
GICSP emphasizes a balanced risk management process where impact or consequence is a critical criterion, especially in ICS environments where safety and critical infrastructure availability are paramount.
