@scottalanmiller said in Thoughts on how I could improve my network security?:
But, like all things of this nature, I've presented my side as to "why" keeping firewalls and the things considered "UTM functions" in separate places.
Now, some feel the opposite. For those that want to say that UTMs (putting lots of applications together onto the router/firewall box) is better than the normal industry standard practice of keeping applications isolated, please present your reasons for wanting that. I've presented solid reasons, that you might not agree with, for why I'd follow industry best practice here. I don't remember anyone saying why they'd do the opposite, only questioning why I'd not do it, which isn't the same as presenting a reason.
So I'm asking... what's the reasons for going against the grain in this one case? There are exceptions to most every rule, but I've not seen anyone anywhere ever present an argument for UTMs, only that they'd use them despite the reasons against them.
It is not only the IT industry that does this. The audio/video industry does this also, maybe others do too. In a business or enterprise setup we never use equipment that contains all the functions in a single box, which is analogous to UTM's in the IT space. We separate out all the functions because it is more versatile, more reliable, usually more cost effective, and easier to troubleshoot issues. Do companies make boxes that include a pre-amp, amp, tuner, networking, storage, disc players, switchting, video processors and sound processors? Yes they do. Should you ever use one if your a business? Absolutely not if you can avoid it. If you have no other choice, like if someone else bought it and its your job to support then you just have to make do. If you have the budget then use separates, whether vm's or physical devices if you can't use a vm.
