These security issues can come from unintended disclosure of information by employees or others, most likely by posting on Facebook or perhaps on a personal blog. You also need to be concerned about hackers and bad employees that are going to steal your information for a variety of different uses. What are some of the things that you can do to offer your company the data security that it needs?
One thing that you can do is to employ some form of file encryption which will make the data on your computer useless to anyone on the outside. This can either be done through an installed software or through installing self encrypting drives (Source: Self Encrypting Drives by WinMagic). It is also a good idea to lock down your network as tightly as possible by hiring an IT team that is able to do so throughout the entire network. Along with locking down the network, you would also want to run antivirus software on every computer attached to the network to keep any problems from occurring.
Finally, it’s important for you to have a backup of all of the data that is secure. You can either back up the data on an external drive and take it with you at the end of the day or you can back it up online, if your business model permits. Just make sure that you are handling the data in compliance with any regulatory agencies that are monitoring your business.
