Five Big Ten universities, led by Indiana University, have established OmniSOC, a cybersecurity operations center leveraging the Elastic Stack to enhance threat detection and response times across their campuses. This collaborative initiative, involving Indiana University, Northwestern University, Purdue University, Rutgers University, and the University of Nebraska-Lincoln, aims to protect students, faculty, and staff from cyber attacks by sharing threat intelligence and using advanced analytics. OmniSOC operates using components of the Elastic Stack, such as Elasticsearch, Kibana, Beats, and Logstash, to ingest and analyze vast amounts of data from thousands of systems, enabling rapid identification and mitigation of cyber threats. The initiative reflects a broader trend of using data-driven approaches and predictive analytics to enhance cybersecurity, with plans to expand its services and membership beyond the Big Ten Academic Alliance. The use of the Elastic Stack not only provides deep visibility into security information but also promises future applications, such as a multi-petabyte digital archive and additional operational logging use cases.
