Anyone know the difference between a 'host-based' and an OS-based firewall. Seems to me that if its host-based, well there has to be an OS underneath :)
Also another stupid question. If you have an application-level gateway, which is a type of firewall actually (from what I know), would you typically have another separate 'gateway' to the internet? Or does this gateway / firewall function as a hybrid device - including gateway & firewall functionality in 1 device.
