GIAC Global Industrial Cyber Security Professional (GICSP) Sample Questions (Q90-Q95):

NEW QUESTION # 90
An attacker has a goal of obtaining information stored in an ICS. Why might the attacker focus his efforts on the operating system rather than the ICS application?

Answer: A

Explanation:
In ICS environments, attackers often target the operating system (OS) rather than the ICS application itself because the OS controls and supports the applications running on it. Gaining control over the OS gives attackers the capability to:
Access all files and data processed by applications
Install malware or tools that operate beneath or alongside ICS applications Manipulate or intercept data without detection While hardening guidance may exist for both OS and applications, the OS is a more fundamental layer and usually presents a broader attack surface. Therefore, controlling the OS (D) effectively provides access to all applications, making it a strategic target for attackers seeking sensitive information.
This approach aligns with the GICSP's focus on understanding layered defenses and attack vectors at all levels of the ICS stack, including the operating system.

NEW QUESTION # 91
Which type of attack could compromise Level 3 systems and affect business planning and logistics?
Response:

Answer: D


NEW QUESTION # 92
Which type of attack specifically targets wireless networks by overwhelming them with excessive traffic, causing a loss of availability?
Response:

Answer: D


NEW QUESTION # 93
A brewer uses a local HMI to communicate with a controller that opens a pump to move the workfrom the boil kettle to the fermentor. What level of the Purdue model would the controller be considered?

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The Purdue Enterprise Reference Architecture (PERA) model, commonly used in ICS security frameworks like GICSP, segments industrial control systems into hierarchical levels that correspond to the function and control of devices:
Level 0: Physical process (sensors and actuators directly interacting with the process) Level 1: Basic control level (controllers such as PLCs or DCS controllers that execute control logic and command actuators) Level 2: Supervisory control (HMIs, SCADA supervisory systems that interface with controllers) Level 3: Operations management (Manufacturing Execution Systems, batch control, production scheduling) Level 4: Enterprise level (business systems, ERP, corporate IT) In this scenario, the controller opening the pump is a device executing control logic directly on the process, placing it at Level 1. The local HMI used to communicate with the controller is at Level 2, supervising and providing operator interface.
This classification is foundational in GICSP's ICS Fundamentals and Architecture domain, which emphasizes clear understanding of network segmentation and device role for security zoning.
