Increased focus on protection from terrorism, espionage, cybersecurity and other malicious crimes has led to increased academic interest in the topic of security, especially in risk and safety studies. This article aims to investigate the conceptual and scientific demarcation of security in contrast to safety, and discuss the status of security as an independent science. Security is a multifaceted concept and academic definitions often distinguish security from safety in terms of intentionality. However, intentionality also plays a part in safety research thus this is not a sufficient parameter for distinguishing the two fields. The dichotomy of nonmalicious versus malicious is suggested as a means for differentiation. A new definition of security that incorporates elements associated with the current security research field is proposed. Security can be defined as the perceived or actual ability to prepare for, adapt to, withstand, and recover from dangers and crises caused by people's deliberate, intentional, and malicious acts such as terrorism, sabotage, organized crime, or hacking. The conclusion is that before security can be established as an independent discipline, it is necessary to determine what concepts and theories are related to the field, what levels of and objects in society should be included, in addition to the interrelationships and interdependencies with other disciplines.
