Can somebody advise how secure is it to place a L2 switch on my network perimter? I heard that it is easy to flood a switch that's exposed to the internet but I'm not sure how accurate is this sentence because I'm aware that switches are not stateful devices so what concerns should I worry about when exposing my switch to the internet?
Thanks for the link, let's assume I have border router where the internal interface is connected to a switch and then to my IPS unit. My concern is if I were under a DoS attack or a heavy rate-based attack my border router or my switch will fail before even my IPS takes over. Your advise please.
