A protection system is designed to safeguard assets and ensure their reliability through effective measures. One of the key recommended characteristics of such a system is diversity. Having a diverse protection system means incorporating different techniques, components, and methodologies to mitigate risks from various sources. This approach enhances overall effectiveness because it reduces the risk of all protective measures failing simultaneously due to common vulnerabilities or faults.

Diversity in a protection system allows for redundancy and increases resilience, as different methods can compensate for each other's weaknesses. If one protective measure fails or is compromised, others remain in place to maintain the integrity of the system. This characteristic is particularly important in environments where risks can vary significantly and where a single point of failure could lead to substantial losses or damage.

In contrast, characteristics such as complexity can hinder system performance, as intricate systems may become challenging to manage and maintain. A simplistic approach may not adequately address the variety of risks encountered. Homogeneous systems, which rely on a single type of protection, may expose assets to greater risk if that form of protection fails. Thus, the emphasis on diversity serves to create a more robust and reliable protection framework.
