Security is a very general, broad field, and touches every aspect of development, deployment, support, among other areas. Per the (ISC)2, there are 10 domains, and include Physical security, in addition to the "Software" aspects. The intent of information security is to protect the confidentiality, integrity and availability of information. Various security professionals also have added other aspects to these attributes, but in general, these appear to be the most popular. Another aspect of security is that the measure to protect some piece of information should not cost more than the value of the information being protected.
