Which of the following is considered a physical asset crucial for preventing cyberattacks?

C. The workstations are considered a physical asset crucial for preventing cyberattacks because they serve as the primary interfaces where users access corporate networks and sensitive information. Properly secured workstations can significantly mitigate risks associated with cyber threats. This includes ensuring that antivirus software is installed, operating systems are updated, and security protocols are followed. Since they are directly involved in the execution of various tasks that may involve sensitive data, maintaining their security is vital for overall cybersecurity measures within an organization.

While employees play a critical role in security awareness and practices, and buildings provide a physical environment for operations, it's the workstations that directly interact with the digital environment vulnerable to cyber threats. Similarly, power lines are essential for operational continuity but do not specifically contribute to preventing cyberattacks. Investing in secure workstations is a proactive approach toward reducing the likelihood of successful cyberattacks and protecting company assets.
