D
Information Availability can be defined in terms of:
Accessibility
Information should be accessible to the right user when required.
Reliability
Information should be reliable and correct in all aspects. It is “the same” as what was stored and there is no alternation or corruption to the information.
Timeliness
Defines the time window (a particular time of the day, week, month, and year as specified) during which information must be accessible.
For example: if online access to an application is required between 8:00 am and 10:00 pm each day, any disruption to data availability outside of this time slot is not considered to affect timeliness.
