Security systems in the old fashioned meaning of the word, a system of security to keep us and your equipment safe, such as from someone physically breaking in to your building and stealing your equipment. Newer meaning of the term, security, especially in the context of computers, often means, security from someone or something hacking into your computer, stealing passwords, and electronic activity of that nature, which can be done from almost anywhere.
The old fashioned meaning of security is far from obsolete, as the more computer equipment that is developed and keeps our computer system free from electronic disruption, the more systems we are going to need to keep them safe, from burglary, etc. These, old-fashioned, systems, are becoming advanced using new technology.
