NEW QUESTION # 90
Which of the following technologies is no longer considered secure?
Answer: C
Explanation:
Secure Sockets Layer (SSL) is no longer considered secure due to known vulnerabilities and cryptographic weaknesses. Modern standards require the use of newer versions of Transport Layer Security (TLS), and similarly, DES is deprecated for strong security. However, the best and most universally referenced example is SSL, as major industry and regulatory bodies recommend disabling SSL entirely in favor of TLS 1.2 or above.
Reference: ISA/IEC 62443-3-3:2013, Section 4.2.3.7 ("Cryptographic protections"); NIST SP 800-52 Rev. 2.
NEW QUESTION # 91
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 # 92
During the operation of an IACS, who is responsible for executing the Security Protection Scheme (SPS) process measures and responding to emerging risks?
Answer: D
Explanation:
The asset owner holds ultimate responsibility for implementing and maintaining security measures, including the Security Protection Scheme (SPS) during the operational phase of the lifecycle. According to ISA/IEC
62443-2-1 and ISA/IEC 62443-1-1, the asset owner is tasked with ensuring that the necessary security policies, procedures, and controls are effectively executed and maintained.
"The asset owner shall define and maintain the operational security policies and procedures, ensuring the execution of the protection scheme and risk mitigation actions."
- ISA/IEC 62443-2-1:2010, Section 4.3
Furthermore, ISA/IEC 62443-1-1 clearly defines the roles and responsibilities of the asset owner in terms of operational security enforcement and ongoing risk response.

ISA/IEC 62443-2-1:2010 - Section 4.3

NEW QUESTION # 94
In what step of the development process of the CSMS is "Establish purpose, organizational support, resources, and scope" taken care of?
Answer: D
Explanation:
The first step in the Cyber Security Management System (CSMS) development process is to "Initiate the CSMS program," which involves establishing its purpose, obtaining organizational support, allocating resources, and defining the program's scope. These foundational activities are required to ensure that the program is properly structured and supported before detailed risk assessments or architecture planning are performed.
Reference: ISA/IEC 62443-2-1:2009, Section 5.1 ("Initiate the CSMS program").
