I have installed FreePBX on a server hosted at an external hosting provider, and I would like to know if I did enough to secure the system. If you guys have any tips, tell me
All extensions have a strong password
Only the required ports are open, and only to a few IP-adresses (they are static)
Backups are made every night
Updates are installed just after the backup every night
Admin Panel is only reachable from my (static) IP.
Voicemails are being send by e-mail
Maximum five calls out are possible at the same time
Depends how critical your data is, Normally i say a weekly backup is enough
Good practice is to run manually again the backup job after doing updates, so you can monitor and see what actually happens, also so you have a backup with the updated modules.
If this is your first time installing/using FreePBX, you are good, man!!
