ISA/IEC 62443 Cybersecurity Fundamentals Specialist Sample Questions (Q11-Q16):

NEW QUESTION # 11
Which of the following refers to internal rules that govern how an organization protects critical system resources?
Available Choices (select all choices that are correct)

A. Legislation
B. Formal guidance
C. Security policy
D- Code of conduct

Answer: C

Explanation:
A security policy refers to internal rules that govern how an organization protects critical system resources, such as industrial control systems (ICS). A security policy defines the objectives, scope, roles, responsibilities, and requirements for securing the ICS environment, as well as the procedures and guidelines for implementing, monitoring, and enforcing the security measures. A security policy also establishes the baseline for assessing and managing the security risks to the ICS, and for ensuring compliance with relevant standards, regulations, and best practices. A security policy is a key component of the ICS security program, and it should be documented, communicated, and reviewed regularly.
The other choices are not correct because:
* A. Formal guidance. Formal guidance refers to external sources of information and recommendations that can help an organization improve its ICS security posture, such as standards, frameworks, guidelines, and best practices. Formal guidance is not an internal rule, but rather a reference that can be used to develop, implement, and evaluate the security policy and controls. For example, the ISA/IEC
62443 series of standards provide formal guidance on how to secure ICS from cyber threats1.
* B. Legislation. Legislation refers to external laws and regulations that impose legal obligations and penalties on an organization for its ICS security performance, such as the NERC CIP standards for the electric sector2, or the EU NIS Directive for critical infrastructure operators3. Legislation is not an internal rule, but rather a compliance requirement that must be met by the organization. Legislation may also influence the security policy and controls, as the organization needs to align its security objectives and practices with the legal expectations and consequences.
* D. Code of conduct. A code of conduct refers to a set of ethical principles and values that guide the
* behavior and decision-making of an organization and its employees, such as honesty, integrity, respect, and accountability. A code of conduct is not an internal rule for protecting critical system resources, but rather a general norm for conducting business and maintaining a positive reputation. A code of conduct may also support the security policy and culture, as it can foster a sense of responsibility and trust among the ICS stakeholders.

* 1: ISA/IEC 62443 Standards to Secure Your Industrial Control System
* 2: NERC Critical Infrastructure Protection Standards
* 3: EU Network and Information Systems Directive

NEW QUESTION # 12
Which of the following can be employed as a barrier device in a segmented network?
Available Choices (select all choices that are correct)

A. VPN
B. Unmanaged switch
C. Domain controller
D. Router

Answer: D

Explanation:
A router and a VPN can be employed as barrier devices in a segmented network. A barrier device is a device that controls the flow of traffic between different network segments, based on predefined rules and policies1. A router is a device that forwards packets between different networks, based on their IP addresses2. A router can act as a barrier device by applying access control lists (ACLs) or firewall rules to filter or block unwanted or malicious traffic2. A VPN is a technology that creates a secure and encrypted tunnel between different networks, such as a remote site and a corporate network3. A VPN can act as a barrier device by encrypting the traffic and authenticating the users or devices that access the network3. A VPN can also prevent unauthorized access or eavesdropping by outsiders3.
