Watson for Cyber Security uses cognitive technology and deep domain expertise to detect and stop security breaches before they cause damage, at a speed and scale never possible before. Unlike programmable systems, cognitive technology is based on training systems that can understand, reason and learn to sense what’s coming – then communicate that in natural language. This video illustrates the process of training Watson for Cyber Security by defining the language of security, annotating representative documents, and then manually making correlations between terms. Watson can then, on its own, learn the language and connections needed to respond to questions from security professionals.
