NEW QUESTION # 74
A company discovers malware on a portable USB device used within their IACS environment. According to the document, which SP Element and controls would be MOST relevant to address this issue?
Answer: C
Explanation:
According to ISA/IEC 62443-2-1, SP Element 4 is focused on system integrity and includes controls such as component hardening and managing dedicated portable media (e.g., USB drives). These controls help mitigate malware risks from removable devices.
"SP Element 4: System integrity. This element includes controls for system hardening and the use of dedicated, protected portable media to reduce infection risk and prevent unauthorized software installation."
- ISA/IEC 62443-2-1:2010, Clause 4.3.4 - SP Elements
While SP Element 7 (Incident Handling) may be involved post-discovery, the primary preventive control is under SP Element 4.

NEW QUESTION # 75
How does ISA-62443-2-1 suggest integrating the IACS Security Program (SP) within an organization?
Answer: B
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 # 76
Which of the following is NOT listed under Organizational Security Measures (SP Element 1)?
Answer: A
Explanation:
ISA/IEC 62443-2-1 defines SP Element 1 - Organizational Security Measures as the set of governance, policy, and people-focused controls that establish the foundation of an IACS Security Program. These measures are organizational in nature and are intended to create accountability, awareness, and structured risk management.
Step 1: Scope of SP Element 1
SP Element 1 includes activities such as:
* Security policy definition
* Roles and responsibilities
* Personnel security (e.g., background checks)
* Security awareness and training
* Supply chain security governance
These controls ensure that people, processes, and third-party relationships support cybersecurity objectives.
Step 2: Why malware protection does not belong here
Malware protection is a technical control, not an organizational measure. In ISA/IEC 62443, malware protection is addressed under SP Element 4 - Component Hardening, which focuses on endpoint protection, anti-malware mechanisms, and secure configurations.
Step 3: Why the other options are valid
* Background checks are explicitly part of personnel security.
* Supply chain security is a key organizational concern.
* Security awareness training ensures staff understand their responsibilities.
Therefore, Malware protection is not listed under SP Element 1.
NEW QUESTION # 77
Which of the following is NOT a strategy for deploying a WAN?
Answer: A
Explanation:
A Local Area Network (LAN) is not a strategy for deploying a Wide Area Network (WAN). WAN deployment strategies include using the public Internet, private enterprise WANs, or carrier-managed WANs.
LANs, by definition, serve local, not wide-area, connectivity. ISA/IEC 62443 standards refer to different strategies for extending network communications over broader geographic regions, but do not classify LAN as a WAN deployment option.
Reference: ISA/IEC 62443-3-3:2013, Section 4.2.3.4 ("Communications network technologies"); Glossary definitions for LAN and WAN.
