I'm not a security expert but is having local firewalls (enabled on different machines) necessary if you're already running hardware firewalls, like Netgear, that controls in/outbound connections?

Does it just added another layer of protection? Thanks!

Necessary for whom? The environment needs to be well described before 'necessity' can be discussed. Here (where I'm posting from), the answer would be "No." -- Tom

Speaking from a PC and Network Security standpoint, yes, you should. Your Network Firewall should be protecting you on a network level from intrusions, but in most cases, it will not protect the local machine. That is where the software firewall on the local machine comes in. The software firewall should be easily configurable to allow certain types of connections to the local machine, but should be scanning for anything that is not allowed for.

They're not foolproof but host-based firewalls are another security hoop so to speak and are usually recommended. They can help prevent LAN users from accessing resources they shouldn't access and also help thwart malware outbreaks. Yet, still, it depends on what you're trying to accomplish.
