Noisy detection is the term used in cybersecurity and surrounding technical fields to refer to the occurrences of when Security Information and Event Management (SIEM) sends many false-positive alerts to the security operations team. A typical enterprise has the responsibility to pay attention to hundreds or thousands of false-positive alerts daily which creates “noise” in the system and prevents the security team from being able to focus on real malicious threats by forcing them to investigate benign alerts. Noisy detection can distract cybersecurity teams from the threats that matter and allow real threats to infiltrate the organization’s system.
The number of false-positive alerts, or noise, an organization faces each day can be overwhelming and highlight the lack of resources many security operation centers face such as lack of personnel. By having a detection system that is able to reduce the noise, the security team is able to function more efficiently and effectively.
