Kestrel is an open-source programming language for threat hunting that is used by Security Operations Center (SOC) analysts and other cybersecurity professionals. IBM Research and IBM Security jointly developed the language to enable threat hunters to express hunts in an open, composable threat hunting language. The language is designed to take advantage of the collective learned experience of the threat hunting community ‘ and enable that to be combined with the power of machine learning and automation to speed response to threats,’ said Jason Keirstead, CTO of Threat Management for IBM Security.
