Which of the following describes a potential cyber threat to the electrical grid?

The correct answer, which identifies disruption caused by hacking attempts, is pivotal in understanding modern threats to the electrical grid. In today's interconnected world, cyber threats have become increasingly sophisticated and prevalent. Hacking attempts can lead to unauthorized access to grid control systems, potentially manipulating or shutting down critical infrastructure. This can result in service interruptions, data breaches, and compromised safety protocols that may endanger public safety and cause widespread outages.

Recognizing hacking as a serious cyber threat emphasizes the importance of robust cybersecurity measures to safeguard against vulnerabilities that could be exploited by malicious actors. Such efforts include enhancing encryption methods, regularly updating software, and conducting continuous monitoring to detect and mitigate potential intrusions before they can cause harm.

The other options represent various challenges to the electrical grid but do not categorize as cyber threats. Electricity theft relates to unauthorized consumption of power, which is a physical and economic issue rather than a result of cyber activities. Natural disasters highlight environmental risks that pose threats to infrastructure, while loss of renewable energy sources discusses energy supply concerns but does not directly involve cyber vulnerabilities.
