NEW QUESTION # 135
According to ISA/IEC TR 62443-1-5, which documents can be referenced when creating a security profile?
Answer: B
Explanation:
ISA/IEC TR 62443-1-5 provides formal guidance on the creation and structure of cybersecurity profiles within the ISA/IEC 62443 framework. A security profile is intended to tailor existing requirements to a specific industry sector, application, or use case without altering the integrity of the base standard.
Step 1: Purpose of a security profile
The technical report clarifies that profiles are selections and combinations of existing requirements, not a mechanism to invent new controls. Profiles ensure consistent application of ISA/IEC 62443 while addressing sector-specific risk, regulatory, or operational needs.
Step 2: Authorized source documents
TR 62443-1-5 explicitly states that security profiles may reference requirements from:
* ISA/IEC 62443-2-1 (asset owner security program requirements)
* ISA/IEC 62443-2-4 (service provider requirements)
* ISA/IEC 62443-3-3 (system security requirements)
* ISA/IEC 62443-4-1 (secure product development lifecycle)
* ISA/IEC 62443-4-2 (technical component requirements)
These documents collectively cover organizational, system, and component security.
Step 3: Why other options are incorrect
* Limiting profiles to only Parts 3-3 and 4-1 excludes governance and lifecycle requirements.
* Parts 1-1 and 1-2 are foundational and definitional, not requirement sources.
* Referencing standards outside the 62443 family violates the intent of maintaining internal consistency.
Step 4: Standard integrity
By restricting profiles to these documents, ISA ensures profiles remain interoperable, auditable, and certifiable.
Thus, Option C is the only correct answer.
NEW QUESTION # 136
What is a key aspect of the relationship between physical security measures and cybersecurity?
Answer: A
Explanation:
ISA/IEC 62443 emphasizes that physical security and cybersecurity are interdependent and must complement each other to provide robust protection for industrial automation and control systems (IACS). Physical security measures (like locks, fences, access cards) protect against unauthorized physical access, while cybersecurity measures protect against digital threats. Both must work together; for example, a cyber attacker might gain physical access to a control cabinet or a physical intruder might exploit weak network security.
Reference: ISA/IEC 62443-2-1:2009, Section 4.2.5 ("Physical and environmental security"); ISA/IEC 62443-
1-1:2007, Section 4.5.
NEW QUESTION # 137
How many security levels are in the ISASecure certification program?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
The ISASecure certification program, aligned with the ISA/IEC 62443 standards, defines three distinct security levels that categorize the robustness of industrial control systems against known cybersecurity threats. These levels are designed to provide a scalable approach to securing industrial automation and control systems, with each level offering a higher degree of security. The levels are typically identified as SL1 (Security Level 1), SL2 (Security Level 2), and SL3 (Security Level 3), each addressing increasingly stringent security capabilities and resilience against cyber attacks.

At Layer 4 of the Open Systems Interconnection (OSI) model, what identifies the application that will handle a
packet inside a host?

Answer: C
NEW QUESTION # 139
What is the FIRST step required in implementing ISO 27001?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
The first step in implementing ISO 27001, an international standard for information security management systems (ISMS), is to perform a security risk assessment. This initial step is critical as it helps identify the organization's information assets that could be at risk, assess the vulnerabilities and threats to these assets, and evaluate their potential impacts. This risk assessment forms the foundation for defining appropriate security controls and measures tailored to the organization's specific needs. Starting with a risk assessment ensures that the security controls implemented are aligned with the actual risks the organization faces, making the ISMS more effective and targeted.
ISA/IEC 62443 Cybersecurity Fundamentals References:
* Although ISO 27001 is not part of ISA/IEC 62443, it shares common principles in cybersecurity management by starting with a comprehensive understanding and assessment of security risks, which is a fundamental aspect in both standards for setting up effective security practices.
