ABSTRACT: This paper presents an
in-depth understanding of Availability, which is one of the important pillars
of Information Security and yet is not taken too seriously while talking about
the security of an information system. The paper highlights the importance of
Availability w.r.t. Security of information and the other attributes of
security and also gives a realistic shape to the existing CIA triad security
model. An in-depth understanding of the various factors that can impact the
Availability of an information system (Software, Hardware and Network) is
given. The paper also gives a categorization of the type of Availability that a
system can have. The paper also explains the relation between Availability and
other security attributes and also explains through what issues an information
system may go while providing Availability.
