Step-by-step explanation:
The question at hand addresses one of the essential steps in preventing cyber-hacking attacks within an organization. Of the provided options, Test and train employees is a crucial step to enhance cybersecurity.
Although writing a policy is an integral component of a good cybersecurity strategy, and prohibiting mobile device use might reduce risks, these are not as proactive and effective as engaging employees in regular training and simulated cyber-attack scenarios.
Regular cybersecurity training can significantly mitigate the risk of attacks by educating employees about common threats such as phishing, social engineering, and malware. Testing can involve drills or simulated attacks that help gauge how employees would react in a real-life scenario.
It also helps identify weaknesses in the current security posture that can be rectified before a real threat materializes. A combination of policies, technology, and training can form a robust defense against potential cyber threats.
