GIAC Global Industrial Cyber Security Professional (GICSP) Sample Questions (Q32-Q37):

NEW QUESTION # 32
What can be configured on the router so that it can most effectively implement and enforce zones for the shown subnets?

A. 802. 1x protocol
B. Secure Shell
C. Access control lists
D. MAC-based port security

Answer: C

Explanation:
The diagram shows multiple subnets/zones (Levels 0-3) connected via routers and switches. To enforce traffic flow policies between these zones/subnets, the router should implement Access Control Lists (ACLs) (B).
ACLs can:
Filter traffic between subnets based on IP addresses, ports, and protocols Enforce security boundaries as per ICS segmentation principles (A) MAC-based port security controls device-level access but is less effective for inter-subnet traffic control.
(C) Secure Shell (SSH) is for secure device management, not traffic control.
(D) 802.1x provides port-based network access control but is less relevant for routing traffic between subnets.
GICSP highlights ACLs as fundamental tools for network segmentation enforcement in ICS.

NEW QUESTION # 33
Implementing VLANs can provide which of the following?

A. Stopping unauthorized access to ICS controller diagnostic ports
B. Sandboxing ICS application memory from other system resources
C. Segmenting control device traffic from other network services
D. Separation of duties for different guest OSes on a virtual host

Answer: C

Explanation:
VLANs (Virtual LANs) allow logical segmentation of a physical network, which can be used to separate control device traffic from other network services (A), improving security and performance.
Sandboxing (B) relates to application or OS memory isolation, not VLANs.
Separation of duties for guest OSes (C) is related to virtualization, not VLANs.
Preventing access to diagnostic ports (D) requires port security or access control, not VLAN segmentation alone.
GICSP highlights VLANs as a fundamental technique for network segmentation in ICS security architectures.

NEW QUESTION # 34
For application-aware firewalls filtering traffic between trust zones, which of the following policies should be applied to a packet that doesn't match an existing rule?

A. Default deny
B. Application deny list
C. Application allow list
D. Default alert

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In the context ofIndustrial Control Systems (ICS)andOT network security, the principle of least privilege and explicit access control is fundamental for protecting critical infrastructure assets. According to the GICSP framework, when usingapplication-aware firewallsbetween different trust zones (e.g., corporate network to OT network), any traffic that doesnot explicitly match a defined ruleshould be blocked by default. This is referred to as the"default deny" policy.
* Default denymeans that unless traffic is explicitly allowed by firewall rules, it should be denied. This ensures that no unknown or unauthorized packets traverse trust boundaries, reducing the attack surface significantly.
* Thedefault alertoption (A) is useful for monitoring but does not prevent unauthorized access, so it's insufficient as a security control.
* Application deny list(C) andapplication allow list(D) refer to sets of permitted or denied applications, but the firewall still needs an overarching policy to handle unmatched packets; that policy must be deny for safety.
This approach is emphasized in theICS Security Architecture and Network Segmentationdomain of GICSP, reinforcing that all unknown or unexpected network traffic should be blocked unless explicitly permitted by policy. This aligns withNIST SP 800-82 Rev 2guidance on ICS security, which GICSP incorporates.

NEW QUESTION # 35
Which of the following is located in user mode of a typical realtime OS, but in kernel mode of a typical standard OS?

A. Device drivers
B. Interprocess communication
C. Virtual memory
D. Process scheduling

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In many real-time operating systems (RTOS), interprocess communication (IPC) mechanisms (A) operate in user mode to minimize latency and overhead.
In typical standard operating systems, IPC is usually handled by the kernel (kernel mode) for security and control.
Virtual memory (B), device drivers (C), and process scheduling (D) are typically kernel mode in both OS types.
GICSP covers these architectural differences important in ICS device security and performance.

NEW QUESTION # 36
How is a WirelessHART enabled device authenticated?

A. Using a PIN combined with the device MAC address
B. Using a join key to send an encrypted request for the shared network key
C. Using the vendor hard-coded master key to obtain a link key
D. Using a WPA2 pre-shared key entered by an administrator

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
WirelessHART is a secure, industrial wireless protocol widely used in process control. Its security architecture uses a layered approach including encryption and authentication mechanisms to protect communications.
WirelessHART devices authenticate by first using a join key, which is a shared secret configured in both the device and the network manager. The device uses this join key to send an encrypted request to the network manager.
Upon successful authentication, the device receives the network key, which is used for encrypting ongoing communications within the network.
This method ensures that only authorized devices can join the network and participate in secure communications.
WPA2 (A) is a Wi-Fi standard, not used in WirelessHART; the vendor hard-coded master key (C) is discouraged due to security risks; and PIN plus MAC address (D) is not a WirelessHART authentication method.
This procedure is detailed in the GICSP's ICS Security Architecture domain, highlighting wireless device authentication protocols as per WirelessHART specifications.
