What is one outcome of effectively implementing diversity of defense?

Effectively implementing diversity of defense enhances security by utilizing multiple layers and types of defenses against potential threats, which ultimately reduces the likelihood of successful attacks. This approach relies on the premise that if one defense mechanism is circumvented, others will still be in place to protect the system. By diversifying the security measures—such as firewalls, intrusion detection systems, anti-malware tools, and other protective technologies—organizations can create a more robust security posture that complicates an attacker's efforts to penetrate defenses. Thus, even if one layer fails, the presence of diverse defenses makes it significantly harder for an attacker to achieve their goals, leading to an overall decrease in the probability of successful attacks.

In contrast, the other options do not capture the essence of the benefits associated with diversity of defense. For instance, increased complexity in network design could be a byproduct of implementing multiple defenses but does not directly relate to the fundamental goal of improving security. Dependence on cloud security, while potentially a valid concern, does not reflect the broad benefits of having a diverse defense strategy. Lastly, an expanded attack surface is generally considered a disadvantage rather than an outcome, as adding more components can create additional vulnerabilities that attackers could exploit. Therefore, the correct choice recognizes the core
