IF an operating system permits executable objects to be used simultaneously by multiple users
without a refresh of the objects, what security problem is most likely to exist?
A.
Disclosure of residual data.
B.
Unauthorized obtaining of a privileged execution state.
C.
Data leakage through covert channels.
D.
Denial of service through a deadly embrace.
Explanation:
This is a well known issue knew by many programmers, since the operating system is allowing the
executables to be used by many users in different sessions at the same time, and there is not
refreshing every certain time, there will be a disclosure of residual data. To fix this we need to get
sure that objects are refreshed frequently, for added security its better an OS that does not allow
the use of an executable object by many users at the same time.
