Explanation:
The earlier in the process that security is planned for and implement the cheaper it is. It is also much more

more complicated to add at the end. If security plan is developed at the beginning it ensures that security won’t
be overlooked.

A: If you wait to implement security after a system is completed the cost of adding security increases
dramatically and can become much more complex.
B: It is often difficult to add security to a system that has been procured off-the shelf.
C: This implies only a single threat.
