Update your software AT LEAST Weekly (it is automatic, just enable it)
buy antivirus software it is cheap. set it to update daily, and scan at times you don't use the computer (daily)
Encrypt your Device, if you "feel" this slows your computer down, get a solid state drive.
Use Multifactor authentication NOT just a username and password!
NEVER GIVE Anyone your Multifactor codes! EVER!
Use uniquie Passwords for EVERYTHING!
You don't have to remember them, Use a Password Manager like Last Pass
Change username/password on everything when you purchase them, Nothing should have the default username/password, think Routers, Printers, wireless, Security Cameras, any electronics you buy change the password, if it has wifi, network connection, or make a connection to something else, YES it has a password
Don't use open WIFI, Turn on Security WPA2, set a secure password, don't give it to everyone that comes to your business. If you want your clients/guest to use wifi, get a second device set it up as open and keep customers and business equipment separate. Wifi Routers are as cheap as $20 on amazon. Of a little more $100 router and $9 a month you can even adverse on your Wifi! (Contact us if you want to know more about advertising on your wifi firstname.lastname@example.org)
Train your staff, You don't have to write it, there are plenty of free security classes, 1 hour of time to save your business, not a bad investment.
Have a PLAN. What if you get hacked, what if someone makes a mistake and deletes everything? Get a BACKUP DAILY!
