NEW QUESTION # 83
A multinational corporation needs to implement a cybersecurity framework that can be adapted across different countries and industries while allowing continuous improvement. Which feature of the NIST CSF makes it suitable for this purpose?
Answer: D
Explanation:
The NIST Cybersecurity Framework (CSF) is explicitly designed to be flexible, voluntary, and sector- agnostic, making it suitable for diverse environments - including multinational corporations operating in multiple regulatory jurisdictions.
"The Framework is intended to be used by organizations of all sizes, across all sectors and countries. It is technology-neutral and allows for continuous improvement through its tiered implementation and feedback loop."
- NIST Cybersecurity Framework v1.1, Section 1.2 - Framework Overview
This flexibility allows organizations to tailor their implementation to fit their risk appetite, regulatory requirements, and industry practices.

NEW QUESTION # 84
Which of the following activities is NOT listed under the "Patch Testing" phase in the asset owner requirements?
Answer: A
Explanation:
According to ISA/IEC 62443-2-3, patch testing involves several tasks to ensure the patch is safe and effective before deployment. These include:
File authenticity verification
Notification of applicable systems/users
Qualification and verification testing
However, a "removal procedure" is not listed as a standard activity under patch testing - although rollback planning might be a best practice, it is not specifically listed in the test phase.
"Patch testing activities include verification of patch authenticity, notification to relevant stakeholders, and qualification testing in a representative environment."
- ISA/IEC 62443-2-3:2015, Clause 6.1.2 - Patch Testing and Validation

NEW QUESTION # 85
How does ISA-62443-2-1 suggest integrating the IACS Security Program (SP) within an organization?
Answer: C
Explanation:
ISA/IEC 62443-2-1 explicitly requires that the IACS Security Program be integrated into the organization's overall management structure.
Step 1: Integration principle
The standard states that IACS security must align with business processes, governance, and enterprise security management rather than operate in isolation.
Step 2: Alignment with ISMS
Where an Information Security Management System (ISMS) exists, the IACS SP should be embedded within it to ensure consistent risk management, policy enforcement, and continuous improvement.
Step 3: Why other options are incorrect
Standalone security programs create silos. Full outsourcing violates asset owner accountability. Purely technical approaches ignore human and process factors.
Step 4: Operational outcome
Embedding the SP ensures sustainability, consistency, and executive oversight.
Therefore, the correct answer is by embedding it into organizational processes and the ISMS.
NEW QUESTION # 86
What do packet filter firewalls examine?
Available Choices (select all choices that are correct)
Answer: D
Explanation:
Packet filter firewalls, as defined by ISA/IEC 62443 standards on cybersecurity, primarily examine the source, destination, and ports in the header of each packet. This type of firewall does not inspect the packet content deeply (such as its structure or sequence) or maintain awareness of the relationships between packets in a session. Instead, it operates at a more superficial level, filtering packets based solely on IP addresses and TCP/UDP ports. This approach allows packet filter firewalls to quickly process and either accept or block packets based on these predefined criteria without delving into the complexities of session management or the content of the packets up to the application layer.
