This chapter describes the concept of information availability (IAV) which is considered an important element of information security. IAV is defined as the ability to make information and related resources accessible as needed, when they are needed, where they are needed. In the view of the authors, this notion encompasses more than just making sure that the information technology (IT) infrastructure is technically adequate and continuously available, but it also emphasizes other often-ignored attributes of IAV, such as appropriate policies and procedures, an effective security policy, and the establishment of a workable business continuity plan. Thus, the goal of the chapter is to define IAV in the context of information security and elaborate on each of these first and second order determinants of information availability.
