First the advantages. A secure network has much less likelihood of unauthorized access which could result in corrupted data, stolen data, or malicious damage to a database. Some form of encryption is usually used to make data unreadable even if it is stolen. The chief disadvantage is slowdown of the system. Encrypted data must be un-encrypted, users have to be verified, some IP addresses have to be blocked, etc.
Advantage everyone on the network should have access. The disadvantage is that if the network storage is not security protected anyone could gain access
Advantage: Easy to set up Cheap Disadvantage: Lack of security. Thus ad-hoc network is also called unsecure networks.
The only disadvantage will be internet speed.
If a computer system is operating then it should be utilizing network security. So the answer would be all the time.

Network security usually is not that simple to implement and support especially on industrial level. Also it costs a lot of money to have proper equipment.
