Annotation: Offers an analysis of modern protocols and approaches in cyber threat intelligence. The classification of CTI information was given, also the area of applicability for each class was estimated. The classification of CTI protocols and standards was presented with the mapping to CTI levels. An assessment of applicability to describe each CTI level was addressed to each class of protocols and standards. The main conclusion is that further study of the available standards in this area will determine the necessary set of requirements to the process of CTI information sharing, which will allow to face threats more effectively and reduce potential risks.
Keywords: information security threats, cyber threat intelligence, CTI level, exchange protocols.
