                                  질문 # 10
                                  Which of the following types of network devices sends traffic only to the intended recipient node?

                                  정답：B

                                  설명：
                                  An Ethernet switch (C) is a network device that learns the MAC addresses of connected devices and forwards packets only to the port associated with the destination node, reducing unnecessary traffic and improving security and efficiency.
                                  An Ethernet hub (A) broadcasts incoming packets to all ports, not selectively.
                                  A wireless access point (B) broadcasts signals to multiple wireless clients within range.
                                  A wireless bridge (D) connects two network segments wirelessly but forwards traffic according to device types, not necessarily selectively to single nodes.
                                  GICSP's ICS network segmentation and architecture domain underline the use of switches to limit broadcast traffic and reduce attack surfaces.

                                  An organization wants to use Active Directory to manage systems within its Business and Control system networks. Which of the following is the recommended security practice?

                                  정답：B

                                  설명：
                                  The recommended best practice is to use a shared Active Directory domain while deploying a Read-Only Domain Controller (RODC) within the Control system network (D). This approach:
                                  Enables centralized management and authentication consistent with the business network Limits the risk of domain controller compromise in the Control network because RODCs do not store sensitive password information and restrict changes Balances security and operational efficiency by isolating sensitive environments while still leveraging AD's capabilities Options A and C increase complexity or risk by fully separating domains or controllers, while B reduces manageability by mixing domain and workgroup systems.
                                  GICSP highlights RODCs as a means to secure domain services in ICS environments where full domain controllers pose a security risk.

                                  Why is it important to perform regular disaster recovery tests and drills in an ICS environment?
                                  Response:

                                  정답：B


                                  질문 # 14
                                  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.

                                  정답：A

                                  설명：
                                  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.
