NEW QUESTION # 186
If a U.S. federal agency must comply with mandatory cybersecurity requirements under law, which document would they be required to follow?
Answer: C
Explanation:
For U.S. federal agencies, compliance with cybersecurity requirements is mandated under the Federal Information Security Modernization Act (FISMA). Under this act, agencies are required by law to adhere to NIST Federal Information Processing Standards (FIPS).
From NIST documentation and FISMA:
"Federal agencies must comply with the standards and guidelines developed by NIST, including FIPS 199 and FIPS 200, to ensure appropriate levels of information security." NIST FIPS documents are mandatory for federal agencies, while NIST Special Publications (e.g., SP 800-
171) are recommended or apply to non-federal entities (like contractors).
Incorrect Options:
B). ISA/IEC 62443 - While globally recognized, ISA/IEC 62443 is not mandated by U.S. federal law.
C). EU Cyber Resilience Act - Applies only to European Union entities.
D). NIST SP 800-171 - Applies to defense contractors, not directly to federal agencies.

NEW QUESTION # 188
In an IACS system, a typical security conduit consists of which of the following assets?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
A security conduit is a logical or physical grouping of communication channels connecting two or more zones that share common security requirements1. A zone is a grouping of systems and components based on their functional, logical, and physical relationship that share common security requirements1. Therefore, a security conduit consists of assets that enable or facilitatecommunication between zones, such as wiring, routers, switches, and network management devices. Controllers, sensors, transmitters, and final control elements are examples of assets that belong to a zone, not a conduit. Ferrous, thickwall, and threaded conduit including raceways are physical structures that may enclose or protect wiring, but they are not part of the communication channels themselves. Power lines, cabinet enclosures, and protective grounds are also not part of the communication channels, but rather provide power or protection to the assets in a zone or a conduit.

NEW QUESTION # 189
What does ISASecure primarily focus on?
Answer: B
Explanation:
ISASecure is a conformity assessment scheme developed under the ISA Security Compliance Institute (ISCI), an affiliate of ISA. Its primary focus is the certification of IACS (Industrial Automation and Control System) products, systems, and supplier processes for cybersecurity. The program's aim is to facilitate and ensure the cybersecurity of automation and control systems by certifying that products and systems meet the requirements set forth in the ISA/IEC 62443 standards. ISASecure offers certifications such as ISASecure EDSA (Embedded Device Security Assurance), SSA (System Security Assurance), and CSA (Component Security Assurance), all of which are tightly mapped to the 62443 series requirements.
