What is a recommended best practice regarding sensor visibility exclusions?

Narrowing the exclusion scope to specific paths is a recommended best practice regarding sensor visibility exclusions because it helps maintain a balance between data collection and system performance. By targeting specific paths for exclusion, organizations can reduce the amount of unnecessary data that is processed and analyzed while still monitoring critical areas that may be vulnerable to threats. This approach minimizes blind spots, ensuring that essential data remains accessible for threat detection and response while potentially lowering the overhead often caused by monitoring less relevant areas of the system.

When exclusions are too broad, such as allowing all paths for comprehensive data collection, it can overwhelm the system, leading to inefficient performance and possibly missing crucial threat indicators. Similarly, removing exclusions regularly without assessing the impact may lead to performance degradation and disrupt critical monitoring operations. Also, specifying built-in OS directories for efficiency alone doesn’t address the need to focus on specific, relevant paths that are critical for security monitoring. Therefore, narrowing the exclusion scope is key to optimizing both security posture and system performance.
