Ethical Hacking Essentials Practice Test

Which of the following countermeasures helps security professionals secure the cloud network from cryptojacking attacks?

1. Review all third-party components used by the company's websites

2. Implementing stronger password policies

3. Increasing firewall restrictions

4. Regularly updating server software

The correct answer is: Review all third-party components used by the company's websites

Reviewing all third-party components used by the company’s websites is a key countermeasure against cryptojacking attacks because many cryptojacking incidents occur through vulnerabilities in external libraries or plugins integrated into web applications. Cybercriminals may exploit these third-party components to inject malicious scripts that utilize the computing resources of compromised systems to mine cryptocurrency without the owner's consent. This proactive strategy allows security professionals to identify any potentially vulnerable or compromised components, ensuring that the applications and services running on a company’s web platform do not include any components that could be manipulated during a cryptojacking exploitation. Each of the other choices, while valuable for broader security best practices, does not directly address the unique nature of cryptojacking attacks. Stronger password policies primarily help prevent unauthorized access, increasing firewall restrictions may limit general access but not specifically target cryptojacking vectors, and regularly updating server software contributes to overall security by fixing vulnerabilities but does not specifically mitigate the risks associated with external third-party components. Thus, focusing on the third-party components is a more targeted and effective approach to securing the cloud network from these specific types of attacks.
