You can encrypt individual files, folders, volumes or entire disks within a computer, as well as USB flash drives and files stored in the cloud. The purpose of file and disk encryption is to protect data stored on a computer or network storage system.
All organizations, including small and midsize businesses SMBs , that collect personally identifiable information PII like names, birthdates, Social Security numbers and financial information must secure that information. An organization can be sued if a computer containing PII is stolen and the information is leaked or shared.
If a laptop is lost or stolen and the files or disk aren't encrypted, a thief can easily steal the information, so it's a good practice to encrypt your sensitive data, if not your entire hard drive. The thief doesn't even need to know the sign-on password to access the files — it's easy to boot a computer from a USB thumb drive and then access the disks within the computer.
Disk encryption doesn't protect a computer entirely. A hacker can still access the computer over an insecure network connection, or a user can click a malicious link in an email and infect the computer with malware that steals usernames and passwords. Those types of attacks require additional security controls, like anti-malware software, firewalls and awareness training. However, encrypting a computer's files or the entire disk greatly reduces the risk of data theft.
When making decisions regarding encryption, it's important to have a basic grasp on how encryption works. Encryption is a digital form of cryptography, which uses mathematical algorithms to scramble messages, leaving only individuals who possess the sender's cipher or key able to decode the message.
There are two main methods of encryption: symmetric encryption, which involves securing data with a single private key, and asymmetric encryption, which uses a combination of multiple keys that are both public and private. Data in hexadecimal form is scrambled multiple times and utilizes bit, bit or bit keys to unlock, the latter being the strongest. Keys can be substituted with passwords that we create, making the password the only direct way to decrypt the data.
This method is best suited for encrypting files and drives. The only weak spot is the password itself, which hackers may break if it's weak. They're unlikely to strong-arm their way into the data through encryption. Keep in mind that, though bit AES is a strong encryption key, most government regulations require the stronger bit AES to meet certain standards. Asymmetric encryption is used for sending secured messages and other data between two individuals.
On messaging platforms, such as most email services, all users have a public key and a private key. The public key acts as type of address and method for the sender to encrypt their message.
That message is further encrypted with the sender's private key. The receiver can then use the sender's public key to verify the message sender and then decrypt the message with their own private key.
Third-party encryption programs are more straightforward. When you boot the PC, you have to enter the encryption password before Windows can load. The free and open-source VeraCrypt does a good job. The wizard to set up drive encryption is long, but reasonably intuitive. Python Javascript Linux Cheat sheet Contact. Should I encrypt my entire hard drive, or only a partition? Both solutions are acceptable but they have different pros and cons. Tags: Encryption Disk Encryption.
Bitlocker - "Recovery information was successfully backed up to Active Directory", but not really? Then you can select your disk or partition.
If you need to store large files, choose the option to do so now. Having a laptop or hard drive stolen is stressful, but with encryption, you can keep your data safe. Even if you have an obscure piece of hardware or an uncommon operating system, encryption has never been a more accessible form of security.
However, encryption can only protect you from physical threats, and you may still be vulnerable to other forms of cybercrime. With the security of a good antivirus , VPN and cloud backup in place, you can protect yourself from the countless criminals, companies and governments that want your data.
You can also keep your data safe from accidental deletion by using the backup rule. In case you need it, we also have a guide on how to wipe a hard drive.
Have you tried encrypting hard drives before? How did it go? Let us know your thoughts in the comments below. Thanks for reading. I am not seeing anything related to bitlocker show up after I go into system and security on step one. I have Windows 7.
Do I need to manually download bitlocker? Hello Patrick, Bit Locker does not have to be separately downloaded. Bit locker is a feature that is available in only elite versions of Windows 7. This includes Windows 7 Enterprise and, Ultimate.
