      Clearly I have no problems in disagreeing with your statements ;)

      Changing your standard ports for services to non standard is simple attempt at obscurity, and as we all know security through obscurity is not security..  This is security 101

      How does NIST state it – oh yeah "System security should not depend on the secrecy of the implementation or its components."

      If your doing it to say keep your logs a bit cleaner from the bots hitting your port on the outside ok..  But it is not a valid security measure.  And would seem completely pointless on the inside..  And could even lead to problems..  Hey can you get into that server in that remote DC, billy quit and we have the username and passwords but RDP is not coming up ;)

        It could be argued that the single, correct AES256 key in use is simply obscure in a sea of 2^256 possibilities but I digress…

            What gives you the impression it was an attempt at security through obscurity?

              You are literally obscuring the standard port number for common services by moving it to a different location.  It will trick a lot of dumb scans that happen constantly on the Internet but it won't stop a scanner dedicated to finding remote access servers (RDP, SSH, VNC etc) no matter which port they're listening on.  It doesn't take a lot of time to parallel-scan huge swathes of port space per IP address when you have many computers at your command.

                So let me guess you think hiding your SSIDs is good security practice too?

                … think hiding your SSIDs is good security practice?  Yes.

                  I think we are talking cross purposes here.

                  In my original post I do state
                  https://forum.pfsense.org/index.php?topic=97868.msg545715#msg545715
                  "although vpn is still preferred route.
                  "

                  In fact I've said the same thing in a rehashed way right here.
                  https://forum.pfsense.org/index.php?topic=94177.msg526779#msg526779
                  "If you want to hide the fact you have (multiple) port forwards setup for RDP on the internet, setup OpenVPN on another ip address range to get you inside the lan, then change your pfsense portwards from wan to openvpn. The less you expose wan side the better imo.
                  "

                  In this post from this thread https://forum.pfsense.org/index.php?topic=97868.msg546006#msg546006
                  "On the point of having the RDP on different ports within a lan setting, how do you prove it wasnt the admin logging in and rdp'ing onto a machine when the audits show it was the admin username and password used and no cctv exists in the office?"

                  its a different scenario now, just focusing on lan, dont care about wan which is what I think some of you havent let go of, but the premise is that having non default RDP ports lanside can be used to trip someone up who makes assumptions about the lan whilst only being in possession of the admin username & pwd from their workstation.

                  We know its a windows workstation and others exist as thats why we are using RDP, instead of say VNC, Teamview, Goto, etc etc. Trip doesnt stop people getting to their destination, but it can be useful for showing up anomalies where hidden knowledge is not known to the right people.

                  So can you answer the question?

                  If you need to clarify anything more about the lan setup, whats running and whats not, just ask.  ;)

                    I dont like any 2.4GHz frequencies full stop, 900Mhz is better especially when considering an antenna 15metres up has a maximum coverage radius of upto 50Km making it ideal for mesh networks, and tends to be unlicenced in many countries around the world.

                      What does 900Mhz has to do with not broadcasting ssid?  So you think its a good practice not to broadcast it?  rolleyes..

                        I dont use wifi full stop, sure not broadcasting the SSID can make it a little harder for others to spot who dont have things like air crack, but I just dont like that frequency so I dont use it. Besides theres also this.

                        Now 900Mhz is a different frequency all together with totally different properties and is one I do like for mesh networks, but like any over the air network, always encrypt and its also why SETI could ultimately fail when considering advanced intelligent lifeforms may use fibre, copper or laser line of sight communications amongst other communication carrier methods, to reduce the ability of eavesdroppers even though there is still radial beam divergence with some lasers which could potentially enable an eavesdropper.

                            huh?  You know who it makes it harder on - the users of said network, like your buddy that is over and wants to connect to your wifi network that your giving him the creds to do.

                            Who else, yeah grandma across the street prob wont see it on her phone.  As to everyone else, not so much the broadcast of the SSID is only 1 out of 5 different thinks that broadcast the SSID.  Probe responses contain the ssid, associations requests, re-associations requests and probe requests all contain the SSID.  So you turning of beacon is not hiding anything from anyone..

                            You sure do not need aircrack to find the SSID of network that is not sending out beacons.  There are many point and click tools that any user barely able to use google could run that will give show them the SSID from these other methods of finding it.  Easy free one off the top of my head is https://www.acrylicwifi.com/en/wlan-software/wlan-scanner-acrylic-wifi-free/

                            So your tinfoil hat is on so tight you don't use a tablet or laptop in your own home??  WTF??

                              Of course there are other reasons why I dont use wifi which you havent mentioned, but I'll let you find them out in due course if so inclined.  :)
