ISA Cybersecurity Fundamentals Specialist Exam Dumps

Question 6 of 77

Which is the PRIMARY responsibility of the network layer of the Open Systems Interconnection (OSI) model?

Forwards packets, including routing through intermediate routers

Gives transparent transfer of data between end users

Provides the rules for framing, converting electrical signals to data

Handles the physics of getting a message from one device to another

Correct Answer: A

The primary responsibility of the network layer of the OSI model is to forward packets, including routing through intermediate routers. This layer is responsible for determining the best path to send data from the source to the destination across potentially multiple networks.

Question 7 of 77

Which steps are included in the ISA/IEC 62443 assess phase?

Cybersecurity requirements specification and detailed cyber risk assessment

Cybersecurity requirements specification and allocation of IACS assets to zones and conduits

Detailed cyber risk assessment and cybersecurity maintenance, monitoring, and management of change

Allocation of IACS assets to zones and conduits, and detailed cyber risk assessment

Correct Answer: A

In the ISA/IEC 62443 cybersecurity lifecycle, the assess phase involves understanding the system's current state and identifying its vulnerabilities. This phase includes performing detailed cyber risk assessments to understand potential risks and specifying cybersecurity requirements to ensure that the system meets necessary safety and security standards.

Question 8 of 77

What type of security level defines what a component or system is capable of meeting?

Capability security level

Achieved security level

Design security level

Target security level

Correct Answer: A

The type of security level that defines what a component or system is capable of meeting is known as the 'Capability security level.' This term accurately reflects the system's potential and ability to meet specific security requirements.

Question 9 of 77

Which steps are part of implementing countermeasures?

Establish the risk tolerance and select common countermeasures.

Establish the risk tolerance and update the business continuity plan.

Select common countermeasures and update the business continuity plan.

Select common countermeasures and collaborate with stakeholders.

Correct Answer: A

Implementing countermeasures involves establishing the risk tolerance to determine the acceptable level of risk, and selecting common countermeasures to mitigate the identified risks. These steps ensure that the chosen countermeasures are aligned with the organization's risk management strategy and are effective in managing potential threats.

Question 10 of 77

Authorization (user accounts) must be granted based on which of the following?

Individual preferences

Common needs for large groups

Specific roles

System complexity

Correct Answer: C

Authorization (user accounts) must be granted based on specific roles. This is because role-based access control (RBAC) assigns permissions to users based on their roles within an organization, ensuring that they have the minimum access necessary to perform their job functions. This approach enhances security and simplifies management of user permissions.
