Information technology itself is a type of pervasive technology, and its unique feature is its "inclusiveness" and the comprehensive need for it by modern technologies. In this regard, the present study aims to investigate the role of information technology and cognitive warfare terrorism. This research is of a descriptive-analytical type, especially a systematic review, and in terms of method, it is classified as documentary and library research (overview) that has been compiled with keywords related to the subject of information technology and terrorism, cognitive warfare. The population of the present research was books, articles, and documents related to the subject of the research. Next, relying on the theoretical foundations of the research and adopting theses, scientific documents, and research articles available in this field, a discussion has been conducted on new information technologies and terrorism in the field of cognitive warfare. The findings indicate that terrorist information warfare is a war that attempts to use the capabilities of network information systems and devices to operationalize its goals. Also, information terrorism is carried out with the aim of carrying out terrorist activities in the field of information, in which the two factors of weapons and the information warfare environment are considered the most important criteria for success or failure. The results showed that terrorist groups no longer need to establish military training bases to train terrorists, as they did in the past, but can easily achieve their main goals only through computer science experts who help them remotely.
