Mobile data encryption
Since the recent past, businesses have changed the way they function. Today, more and more employees work away from the office. Sales representatives spend most of their time or all their time on the field. Employees are allowed to work from home. Employees travel from one office branch to another frequently. In keeping with these changes, businesses offer their employees mobile devices such as laptops and iPads to carry their work with them. All this is fine until one of these office devices gets lost or stolen. Valuable data is lost – and worse, just may have fallen into the wrong hands. IT security often overlooks this possibility.
Even a password-protected device can be hacked into easily. Or, a screwdriver can be used to remove the hard disc; it is then hooked up to another computer to transfer data. Not only is the loss of company data harmful to the company, but it is also a direct breach of the General Data Protection Regulation (GDPR).
There is a solution to keeping data safe by encrypting data.
What is mobile data encryption?
Mobile data encryption is the process of scrambling all the data on your mobile devices or external media (USB drives and/or memory sticks). The process of encryption rearranges the data in a completely nonsensical manner. The only way to decrypt it is with an encryption key.
Having said that, hackers could perhaps break into an encrypted file. But the process is so difficult and time-consuming that it is impractical to do so.
What are the advantages of mobile data encryption?
- Mobile Data encryption adds an extra level of security to data. So, even if a device were lost or stolen, the encrypted data would still be safe.
- Mobile Data encryption is reliable if it is set up properly. A thief would still be able to reuse the hardware of a stolen device, but they wouldn’t be able to access the encrypted files.
- Mobile Data encryption can be carried out without disruption to your staff. There are several ways to encrypt data, and you can choose one that suits your organisation the best.
What are the different types of data encryption?
There are two ways to encrypt data – data-centric encryption and full disk encryption.
Data-centric encryption is the process of encrypting data as it is stored on the system. There is just a minimum impact on the device’s performance as only important data is encrypted. Data-centric encryption does not apply to the application and operating system files.
If your business’ IT systems access levels are managed centrally, encryption settings can be created to share encrypted data between your employees. So, employees do not have to go through the hassle of encrypting/decrypting them when sending/receiving them.
Full disk encryption involves encrypting all the data on your devices. This is the safest option, and you can be confident that your data is protected. However, the device’s performance may be compromised because every single file must be encrypted/decrypted.
If your business’ devices are managed centrally, external media will not be encrypted.
