Frequently Asked Questions on Full Disk Encryption Software

What is full disk encryption software?

Full disk encryption (FDE) is encryption software that encrypts all the data on a computer's hard disk, including the operating system and installed programs. The full disk encryption software is located on the device's hard drive or disk instead of residing in the computer’s RAM. Full-disk encryption also helps protect data if the equipment is lost or stolen because all of its contents must be entered correctly when you power it up.

What protection does full disk encryption give?

Full disk encryption protects unauthorized access to your files, and all forms of malware are prevented from executing. To access data on an encrypted drive, the hacker must first gain physical access to that computer and find a way past your robust password protections. FDE protects all NAND flash and SSD storage regions with tamper detection hardware for remote mind-reading attacks before they can enter into Secure Mode (S-Mode).

What is the purpose of full disk encryption?

Full disk encryption protects your hard drive and files, including the operating system, applications, and user data. If your computer is lost or stolen, full disk encryption can prevent others from accessing your data by encrypting it before it even leaves your computer. Good full disk encryption will make it almost impossible for your data to get stolen.

How does full disk encryption software work in different OS?

A strong disk encryption software with a strong password is almost impossible to break, but it can be broken with a brute force attack. It is the same technique used to break most types of encryptions. The attacker can make a list of possible passwords and use a computer to test each one by trying to decrypt the encrypted files. This is called a brute force attack.

Does full disk encryption work with Android and iOS?

Full disk encryption software creates a virtual drive in your computer, in addition to your physical hard drive. This virtual drive is encrypted, meaning that all data inside it is protected from being stolen, but the computer can still access the encrypted data when needed. This way, your complete hard drive is encrypted when the computer goes to sleep or you shut it down.

What causes data loss with full disk encryption software?

Data loss with full disk encryption software can occur if there is an interruption in power while the full disk encryption software is active. If the full disk encryption software is interrupted during installation or reformatting, it may close or misbehave in unpredictable ways, leading to data loss or unbootable systems.

How to enable full-disk encryption software?

Enabling full disk encryption is a great way to make sure that you are 100% safe. To enable full disk encryption software:

Step 1:

Download the free encryption software.

Step 2:

Install the free encryption software.

Step 3:

Setup a password for your encryption software and back it up somewhere safe.

Step 4:

Encrypt your hard drive with your new password and file system so you can't access your sensitive information unless you're logged in (this will take some time to complete, depending on how much data is on your computer).

Step 5:

Turn off all internet connections and disable wifi settings to prevent others from logging into your device without permission or stealing sensitive information from you.

Step 6:

If needed, erase any remaining data from the disk that was not encrypted.

How to dump memory from a drive while full disk encryption software is on?

The full disk can be dumped while full disk encryption software is on. It's a good idea to reboot and log in before dumping the full disk. To dump memory from a drive while full disk encryption is on:

Step 1:

Boot from a live CD or DVD that can mount encrypted full-disk.

Step 2:

If full disk encryption is on, allow full system prompt to decrypt the full disk.

Step 3:

Mount partitions.

Step 4:

In /bin, find a script named "offset of" and then locate offset for the partition full of trash.

Step 5:

Destroy and overwrite this range of pages using dd with 149 * 512 bytes (128 KiB) block size. Offset should be specified in decimal numbers.

Step 6:

Reboot back to the original unencrypted entire the disk system.

Step 7:

Repeat steps 1 - 6 for other partitions with full trash on them.

How to set up full disk encryption with dm-crypt luks?

The full disk encryption process is a good way to secure the information on all devices against potential attackers. To configure full disk encryption with dm-crypt luks, follow these steps:

Step 1:

Create the encrypted partition (cryptsetup luksFormat /dev/sda1).

Step 2:

Open encrypted partition (cryptsetup open /dev/sda1 cryptroot).

Step 3:

Mount the partition at bootup time (update-initramfs -c -k all).

Step 4:

Add encrypted partition to fstab (vi /etc/fstab).

Step 5:

Add swap partitions to fstab (vi /etc/fstab).

How to recover the key for full disk encryption?

If you cannot find the full disk encryption key, it is very unlikely that you will decrypt the full disk and retrieve your files. If this is the case, below are the steps that you can make:

Step 1:

Make sure you have synchronized your clock with the atomic clock.

Step 2:

Delete and reinstall your full disk encryption software.

Step 3:

Use a customer-provided recovery key.

Step 4:

Enter the last seven characters of the password as a recovery password.

Step 5:

Reset passwords for all users and re-enable the full disk encryption software.

Step 6:

Restore from backup.

Are there any risks involved in using full disk encryption software?

One potential risk is that you might forget your password and lock yourself out of your hard drive. You should also be careful about what applications you use while your computer is encrypted. Any tools that rely on accessing your hard drives, such as virus scanners and defragmentation software, may not work properly while the disk is encrypted.

What is the major benefit of using full disk encryption software?

Full disk encryption is software that encrypts your hard drive, thereby providing a safe place for you to store your data. It comes in handy when you want to store sensitive information. Also, with full disk encryption software, someone who steals your computer has no way of getting into your private data.
