What is an appropriate frequency for updating operating system (OS) patches on production
servers?
A.
During scheduled rollouts of new applications
B.
According to a fixed security patch management schedule
C.
Concurrently with quarterly hardware maintenance
D.
Whenever important security patches are released
Explanation:
Patches should be applied whenever important security updates are released. They should not be
delayed to coincide with other scheduled rollouts or maintenance. Due to the possibility of creating
a system outage, they should not be deployed during critical periods of application activity such as
month-end or quarter-end closing.
