GIAC Global Industrial Cyber Security Professional (GICSP) 認定 GICSP 試験問題 (Q59-Q64):

質問 # 59
What do the following protocols have in common?

正解：B

解説：
WirelessHART, ISA100.11a, and ZigBee are all wireless communication protocols commonly used in industrial automation and control systems. A key characteristic they share is:
They use RF (Radio Frequency) mesh networking (B) to enable devices to communicate through multiple hops, improving reliability and coverage. Mesh networks allow devices to relay messages, creating a robust wireless infrastructure.
Use of IPv6 (A) is specific to some protocols but not common to all three.
Asymmetric join methods (C) and tunneling legacy protocols (D) are not shared features of all three.
The GICSP materials emphasize mesh network topology as a key feature of these protocols in enabling reliable and secure wireless ICS communications.

質問 # 60
What is the purpose of the traffic shown in the screenshot?

正解：D

解説：
The Wireshark capture filter is set to modbus_tcp.func_code == 5. According to the Modbus protocol specification:
Function code 5 corresponds to Write Single Coil (A).
Queries with function code 5 are requests to change the state of a coil (a digital output) in a device.
The packet details confirm "function 5: Write coil" with the reference number and data.
Other function codes (such as read coils or read registers) use different function codes, so options C and E are incorrect. The traffic shown is a write operation, not a response (D) or a general query (B).

質問 # 61
From the GIAC directory on the Desktop, open gicsp.pcap in Wireshark and filter for USB Capture data.
Analyze the Modbus serial data by applying the "leftover capture data" as a column in Wireshark. In packet
28, what read function is requested? Use the protocol description in the image.

正解：I

解説：
The question requires identifying the Modbus function code in a specific packet (packet 28) from a USB capture analyzed in Wireshark. Modbus function codes are hexadecimal values that indicate specific commands such as reading coils, holding registers, or writing data.
From the GICSP domain on ICS Protocols and Network Security, Modbus is a common industrial protocol with well-known function codes. For example:
0x01 = Read Coils
0x02 = Read Discrete Inputs
0x03 = Read Holding Registers
0x04 = Read Input Registers
0x05 = Write Single Coil
0x06 = Write Single Register
0x08 = Diagnostics
0x09, 0x0a, 0x07 correspond to less common or vendor-specific functions.
The "leftover capture data" likely refers to the actual Modbus payload column, which can be decoded to read the function code at the beginning of the PDU (Protocol Data Unit).
Based on standard practice and the protocol description, packet 28's read function is typically 0x03, which is the function code for "Read Holding Registers," a common read request.
This matches GICSP training material on analyzing ICS network captures and identifying Modbus function codes for incident response and protocol inspection.


質問 # 62
The head of an IT department sent a directive stating that all company communication must use TLS in order to prevent unauthorized disclosure of information. Which part of the C-l-A model is the head of IT concerned with?

正解：A

解説：
The use of TLS (Transport Layer Security) is intended to encrypt data in transit, thereby preventing unauthorized interception and disclosure.
This is primarily a concern with Confidentiality (D), ensuring information is only accessible to authorized parties.
Identity (A) and Authorization (C) involve user verification and access control but are not the main purpose of TLS.
Availability (B) concerns system uptime.
Integrity (D) ensures data is not altered but encryption mainly addresses confidentiality.
GICSP aligns TLS usage with protecting data confidentiality in ICS communications.

質問 # 63
An administrator relaxes the password policy during disaster recovery operations. What is the result of this action?

正解：D

解説：
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.
