GIAC Global Industrial Cyber Security Professional (GICSP) Sample Questions (Q55-Q60):NEW QUESTION # 55
How is a WirelessHART enabled device authenticated?
  • A. Using a join key to send an encrypted request for the shared network key
  • B. Using the vendor hard-coded master key to obtain a link key
  • C. Using a WPA2 pre-shared key entered by an administrator
  • D. Using a PIN combined with the device MAC address
Answer: A
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.

NEW QUESTION # 56
An attacker crafts an email that will send a user to the following site if they click a link in the message. What else is necessary for this type of attack to work?

  • A. The attacker must enclose the URL parameter with <script> tags to run the code
  • B. The attacker must obtain a session cookie from an authorized HMI user
  • C. The user must be authenticated to the HMI interface before clicking the link
  • D. The user clicking the link must be an administrator on the network
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The URL indicates a command to disconnect a sensor on an HMI interface, likely part of a Cross-Site Request Forgery (CSRF) or similar web-based attack.
For such an attack to succeed, the user must be authenticated to the HMI interface before clicking the link (C), so that the request is executed with valid session privileges.
(A) Obtaining a session cookie would help but is not strictly necessary if the user is already authenticated.
(B) User administrative rights may not be necessary depending on HMI design, but authentication is essential.
(D) URL parameters generally don't require script tags unless exploiting Cross-Site Scripting (XSS).
GICSP emphasizes authentication and session management as critical controls to mitigate web-based attacks on ICS interfaces.

NEW QUESTION # 57
An organization has their ICS operations and networking equipment installed in the Purdue model level 3.
Where should the SIEM for this equipment be placed in relation to the existing Level 3 devices?
  • A. On a management subnet in Level 4
  • B. On a different subnet in Level 3
  • C. On a management subnet in Level 2
  • D. On the same subnet in Level 3
Answer: A
Explanation:
According to the Purdue model and best practices outlined in GICSP, Level 4 corresponds to the enterprise or business network, often containing management and security monitoring infrastructure such as Security Information and Event Management (SIEM) systems.
Placing the SIEM on a management subnet in Level 4 (B) keeps monitoring tools separated from the operational control network (Level 3), reducing the risk that a compromised Level 3 device could affect the security infrastructure itself. It also allows the SIEM to collect logs from multiple network segments securely and apply enterprise-wide analysis.
This segregation supports defense-in-depth and aligns with GICSP's emphasis on secure network segmentation and monitoring.

NEW QUESTION # 58
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 alert
  • B. Default deny
  • C. Application deny list
  • D. Application allow list
Answer: B
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 # 59
An engineer has analyzed a subsystem of a power plant and identified physical and logical inputs that could expose the subsystem to unauthorized access. What has the engineer defined?
  • A. A vulnerability scan
  • B. An attack surface
  • C. A threat model
  • D. A risk analysis
Answer: B
Explanation:
By identifying all the points where a system could be accessed or attacked (physical or logical), the engineer has defined the attack surface (B).
A vulnerability scan (A) is an automated tool-based assessment.
A risk analysis (C) evaluates the likelihood and impact of threats.
A threat model (D) outlines potential threat actors and attack paths but not specifically all input points.
Understanding the attack surface is critical to designing effective ICS security controls, as emphasized in GICSP.
