When you have a good backup routine in place, you get the benefit of a lot of peace of mind. Before you relax too much, however, there is an important security dimension to the backed up data that you have to consider. It is advisable to keep the important information in a safe and secure place. Here are some tips to help you make sure that your backed up data is as secure as possible and that your data isn't at undue risk of being compromised.
Encryption
Generally speaking, all of the data that you back up should be encrypted. Encryption ensures that it's just a bunch of garble to anyone without the correct key to unlock it. Most backup systems take care of this for you automatically these days, so you really don't have to spend a lot of time on this, in most cases. Online backup services will also encrypt data for you.
Physical Security
In order for your data to be truly secure, you have to be able to control who has access to it. This requires some sort of room security or keeping the data in a safe where it cannot be accessed by anyone without the right credentials or key. There are several solutions on the market for this need. One of the things to keep in mind is that any physical security you provide should also insulate your data from natural disasters. It's not enough to have your backups in a room if that room is in danger of burning down in a fire, for instance.
Access Control
This is a concern that is closely related to physical security but that's a bit different in some regards. The access control for your backup system usually regards how you prevent access to our servers, drives, tapes and everything else involved in the process. A skilled and nefarious individual can be very creative about how they get access to your data. For instance, if you secure your data tapes but have the tape drive unsecured, someone could easily slip their own tape in the drive and backup-meaning copy-all of your files and take off with them.
Backing up is a process that requires you to pay considerable attention to security. If you're using online backup services, you don't really have to worry about safes or security media, but you do have to make sure that the software used to backup and restore information is secured for unauthorized usage.
