Name:Risk Rule for Dev Sec Ops by Repository id:161bc0ca-4651-4c13-9c27-27770660cf67 version:12 date:None author:Bhavin Patel status:production type:Correlation Description:The following analytic identifies high-risk activities within repositories by correlating repository data with risk scores. It leverages findings and intermediate findings created by detections from the Dev Sec Ops analytic stories, summing risk scores and capturing source and user information. The detection focuses on high-risk scores above 100 and sources with more than three occurrences. This activity is significant as it highlights repositories frequently targeted by threats, providing insights into potential vulnerabilities. If confirmed malicious, attackers could exploit these repositories, leading to data breaches or infrastructure compromise. Data_source:

how_to_implement:Ensure that all relevant detections in the Dev Sec Ops analytic stories are enabled and are configured to create findings or intermediate findings in Enterprise Security. known_false_positives:No false positives have been identified at this time.
