For me, wired is always best and will always be more secure. But if you are using WPA encryption AND setting up your wireless router and access points so that they only accept the MAC addresses on your network. You can change SSIDs from factory defaults and disable SSID broadcasting. Make your passwords at least 8 letters with one capital and one number, and you make up the passwords and not your users so you don't get lotrfrodo.
A very smart networking IT person once told me, "Are there computer hackers out there that can get into your system?" Definitely. But, are there computer hackers out there that want to get into your system? Doubtful."
Think about it. We all worry about protecting our data, but you can only do so much. If someone broke into your old office and took your paper charts, is that your fault. If you had an alarm, and they still got in, what can you do. Unless Anthem hires hackers, not too many people give a damn about your data. Much more important things are:
1. Backups. Lose your patient's data, and that is your fault, and you are screwed.
2. Antivirus and malware. You don't want viruses on your system.
And, if you really don't want people to take your data, you will need to put your server in a locked room, make your permissions flawless, don't give keys to any of your employees, don't have a cleaning service. Walking into your basement or your office and grabbing the server or the hotswappable hard drives is a lot more likely than someone hacking in to your system.
You need really good passwords. Period. I mean what is the most likely schedule for usernames. First initial, last name. Or first name period last name. So, if you are trying to get into SBS via RWW, you simply use your IP address which is everywhere, type in asmith and then try some passwords or use a password software program.
Here is a great example of losing data. I took home a hard drive as always on the weekend to battle against fire or floor, neither of which is rather likely. Then, my house was broken into, and they stole a cell phone, which was on TOP OF the $200 SATA hard drive. I guess they didn't know how much a good hard drive is. That had every bit of data. Yes, it was encrypted but still.
