The main objective behind data encryption is to protect the data stored in network devices. With many organizations collecting personal information from users such as email ID, name, country, birthday, and more, it's important to keep this information safe and secure from attackers.
A single lost or stolen device can lead to a lawsuit if the sensitive data stored on it is breached. With proper encryption procedures in place, you can lower the impact of lost devices carrying sensitive data by a great margin. There are several different types of data encryption methods, including Triple DES, Twofish, Blowfish, RSA, and AE, and we'll discuss some of them here. Below you'll find ManageEngine's recommended encryption procedures for better security and data protection.
Encrypt data on devices through:
Using this method, you can encrypt a selected list of documents; you can select a single file or choose the entire folder. If your organization contains a limited number of resources, then you can use this encryption. You should note that this encryption alone does not ensure complete data security.
With this method, you can create containers and manage the files, folders, and other documents inside these containers, keeping those documents encrypted.
This is the most secure form of encryption; all the files, folders, and volumes are encrypted irrespective of the location they are stored. With this type of encryption, a passcode is require to access the data after encryption. If the passcode is lost or forgotten, retrieving this data is very difficult, even with an expert's assistance.
This is why it's always a good idea to keep a backup of your disk data before encrypting it.
All major OS platforms come with built-in encryption capabilities.
Microsoft BiLlocker is a disk encryption tool that comes with Windows 7, Windows 8.1, and Windows 10.
Follow the steps below to enable BitLocker for your computer:
Apple FileVault comes in handy if you're encrypting data on an Apple device. Similar to BitLocker, FileVault will display a recover key after enabling it, which can either be stored manually or in iCloud.
Linux comes with a built-in encryption tool called dm-crypt, which is automatically installed during OS installation.
With the number of disk encryption tools on the market, it's best to choose the right one after a bit of research. VeraCrypt, DiskCryptor, and Gpg4win are some examples of open-source software that can help you.
Here are few basic practices to keep you on top of data encryption.
