What is Data Encryption

Data encryption is a way of making data unintelligible to someone who is not supposed to read it. By encrypting data and supplying only those authorized to view the data a way of decrypting the data, a decryption key, we can prevent prying eyes from reading our private information.

What makes encryption so important today, is the sheer volume and accessibility of electronic data. Most of the developed world has a digital life; our banking information, our social lives, our business data, personal information and so on. This information is important, so we need a way of protecting our data, making it useless to anyone without our permission to accessing it.

Data Breach

We refer to the loss or exposure of data, as a data breach.
A data breach is defined as the intentional or unintentional release of secure information to an untrusted environment.
There are quite a few ways in which that can happen, but privacyrights.org state that the three most common reasons are:
  1. Hacking or malware
  2. Human error - unintended disclosure
  3. Mobile device

Data Breach Causes

It's a common misconception that hacking and malware are the root cause of modern data breaches. Whilst that's an understandable assumption given that around 51% of data breaches were caused in that way in 2014, taking the number one spot, it's far from the only cause of Data theft. There are many other reasons, and perhaps more worryingly, unintended disclosure was at number two. Unintended disclosure is where data is accidentally sent or exposed to unauthorized recipients, via email for example, so even if your security is keeping the bad guys out, common human error can play a major role in the cause of a data breach.

Human error is exceedingly difficult to prevent, as are so many other factors.

Consequencies

Data is important, It’s what allows most companies to conduct business and stay in business. Much of our business data is highly sensitive... so much so, if the wrong people got their hands on it, it could be very bad for our business.

Let ask some Questions..
What is your most valuable data?
Where is your data right now?
Can you be absolutely be sure it’s where you think it is and only where you think it is?
What are the consequences if it’s lost or stolen?

There are many implications of data loss, including drop in stock price, loss of reputation, loss of customer confidence, etc. More so,all of your data is important and you need to protect it like your business depended on it. If it’s important to you, you can almost guarantee, it will be of interest to someone else! Data breaches are happening all of the time. You can’t miss them; it seems that virtually everywhere you look in the media these days there are reports of new data breaches, and those are ONLY the ones we hear about. Let’s be clear, none of these issues are going away... they are actually becoming more common in places.

Types of Encryption

Sophos offers Data Protection in two parts which are Disk and file Protection.

For maximum protection, we are recommending Safeguard Enterprise Protection which comprises of Full Disk Protection and File Protection with the support of Sophos Mobile control.

File Encryption

As soon as a file is saved, it is automatically encrypted, from this point on, it's safe to store the data in the cloud, send by email, store on a mobile device, etc. The encryption is persistent, so it stays safe wherever you keep it. The best way to ensure that your data is always protected is to use file encryption by default, everywhere and encryption always.

Of course, with all of that, the process has to be transparent so that the users don't even notice it. File encryption in SafeGuard Enterprise Encryption is very unobtrusive, so the user doesn't have to do anything out of the ordinary, like saving data to a specific location or file and they don't have to take any additional steps to make sure their data is secure "it's all automatic".
