Data Availibility

Data Availibility.

Although it is important that data remains secure and confidential, it
is just as important that the data is available when needed. Secured
data that is inaccessible is considered downtime and detrimental to
a business and its ability to serve customers. Technologies such
as clustering and load balancing can help, but if NTFS permissions
are assigned inappropriately, these features will not help.
