Disk Encryption involves converting readable text into a format that only people with a secret decryption code can read. In technical terms, encryption converts plaintext into ciphertext using a cipher. It would be best not to share the decryption key since a malicious person can use it to decrypt the data.
Data encryption has many applications, which include but are not limited to:
1. It facilitates secret communication amongst entities
2. It helps protect data in storage devices such as flash drives and hard disks
3. It helps to protect data in transit, especially through a network
There are many types of encryption, but for this article, we will covecomputer disk encryption.
Sometimes, your computer may fall into the wrong hands after a burglary, or you forget it at an unsafe place, or a thief snatches it while walking on the street. The person may easily access your data since all they need is to remove your hard disk, put it in an enclosure, connect it to a different computer via USB or attach it as a slave disk on your desktop.
It is essential that you encrypt your data because even if a person accesses the physical hard disk, they won’t access your data when it’s encrypted. However, please note that a network sniffer could access your data in transit over a network.
Different companies offer different encryption system solutions. However, all encryption systems use either two standard encryption key techniques: Symmetric or Asymmetric encryption. You can use the following disk encryption options:
Disk encryption is crucial as it will help protect your data if the hard disk or any other storage device falls into the wrong hands. If you are unsure how to encrypt your computer, consult a computer professional to avoid doing it the wrong way.
