What is the GREATEST risk when there is an excessive number of firewall rules?
A.
One rule may override another rule in the chain and create a loophole
B.
Performance degradation of the whole network
C.
The firewall may not support the increasing number of rules due to limitations
D.
The firewall may show abnormal behavior and may crash or automatically shut down
Explanation:
If there are many firewall rules, there is a chance that a particular rule may allow an external connection although other associated rules are overridden. Due to the increasing number of rules, it becomes complex to test them and. over time, a loophole may occur.
