[Freeswitch-users] Brute-force attack

[Peter Olsson]

I use both Windows and Linux systems. As long as you know how to manage both systems, there is not a big difference when it comes to exploits and general security (not anymore anyway, if you use current versions). I would say that the biggest issue here is the knowledge of the people managing the systems. And it's usually more secure to manage a system that you know, then a system you don't know much about, even though that system is considered to be more secure.

Lots has happened since Windows 95 :)

Anyway, for this kind of setup I would also prefer Linux, but mostly for the possibilites with fail2ban etc, which doesn't exist on Windows. I'm thinking of writiling something similar for Windows, hopefully I get som time for that soon...

I would strongly suggest to move your production system to Linux, which is by far secure and controllable then Windows. Right now, if somebody does not breaks into your voip setup using some bruteforce / DOS attack, s/he can still exploit some hole in Windows to crack your security. Windows is simply not secure enough to production grade performance.

Thank you.
