The definition of cybersecurity as an industry is still evolving and emerging. Many industry and military partners define the industry as those tasks that comprise information assurance and information security activities.
The National Security Agency (NSA) defines cybersecurity using the following terms:
- Information Assurance (IA)
Information Assurance comprises measures that protect and defend information and information systems by ensuring their availability, integrity, authentication, confidentiality, and non-repudiation. These measures include providing for restoration of information systems by incorporating protection, detection, and reaction capabilities.
- Information Systems Security (Information Security, ISS, INFOSEC)
Protection of information systems against unauthorized access to, or modification of, information, whether in storage, processing, or transit, and against the denial of service to authorized users, including those measures necessary to detect, document, and counter such threats.
The U.S. Department of Labor identified cybersecurity specialists as "the workers who protect the data and systems in networks that are connected to the Internet. But it is no easy task to deﬁne who, exactly, these specialists are. In part because of that difficulty, their training requirements vary widely. One thing seems certain, however: Cybersecurity is a growing career ﬁeld."
