A Small Business Guide to Computer Encryption

The concept of encryption is difficult to comprehend, yet it’s an essential part of safeguarding your company’s sensitive information. In a nutshell encryption is the process of the process of scrambling text to make it unreadable for anyone who is not authorized to read it. Encode specific documents, folders, or books and whole discs in a pc and USB flash drives and cloud-hosted folders. LLB

Why is encryption so important?

The goal of disk and file encryption is to secure data on the computer or in a network storage system. All businesses, including small and midsize companies (SMBs) who collect private identifiable details (PII) such as birth dates, names, Social Security numbers and financial information should secure the information. A business is liable for legal action if a computer with PII is stole, and the information is release or distribute. Crunch base

If your laptop is stole or lost, and the files or disks aren’t encrypt an intruder can easily access the data. Therefore it’s a great idea to protect your confidential files. Even if it’s you don’t have your whole hard disk. The criminal doesn’t need to know the password for signing-on to gain access to the files. It’s simple to boot up the computer using the USB thumb drive and access the disks inside the computer.

Disk encryption doesn’t protect a computer entirely. Hackers can still gain access to the computer through an unsecure internet connection. Or an individual could click on a malicious link within an email. And then infect the computer with malware that steals passwords and usernames. These kinds of attack require extra security precautions such as anti-malware software or firewalls as well as awareness training. But, encrypting computer files, or even the entire disk significantly decreases the chance from data loss.

Encryption 101 How is it working?

In making choices regarding encryption, it’s essential to understand the basics of how it works. It is a type of cryptography, that uses algorithms to encrypt messages, making only those who have the sender’s encryption or key to read the message.

There are two primary types of encryption methods:

Symmetric encryption that encrypts data with only one private key and Asymmetric encryption. Which makes use of the use of multiple keys which can be both private and public.

The most popular method of secure encryption that is symmetric can describe as Advanced Encryption Standard (AES). That constitutes one of the U.S. security standards use by the government. Hexadecimal data is scramble several times and is encrypt using 128-bit. Keys that are 192 bits or 256 bits to unlock, with the one with the highest strength being the strongest. Keys can be replace with passwords we make which makes the password the sole method of decrypting the data. This method is ideal to secure drives and files. The most vulnerable part could be the password that hackers could breach if the password is weak. They’re unlikely to force in to your information through it. Be aware that even although 128-bit AES is a secure encryption key. The majority of laws require 256-bit AES to conform to certain standards.

Asymmetric encryption

Asymmetric encryption is use to sending encrypted messages as well as other data between two persons. In messaging services, like most email providers every user is provided with both a public and private key. The public key serves as kind of address and is use for the sender to secure their message. The message is then encrypted using the sender’s personal key. The recipient is then able to utilize the public key of the sender to verify the sender of the message and decrypt the message using their private key. If a hacker tries to steal the message won’t be able to access its contents without the private key of the receiver.

Computer encryption types

Individual encrypt folders and files is exactly that and only encrypts the items you provide it to. This option is suitable for documents that are not a lot of business are save on the computer, and it’s better than not having it whatsoever.

A step further is the use of volume encryption which creates a kind of container that is completely encrypted. All folders and files that are created or saved to the container are protect.

Full-disk, also known as whole-disk encryption is the most secure method of computer encryption. It’s completely transparent to users and doesn’t require them save their files to a specific space on the disk. Every folder, file and volumes are protected.

When using full-disk encryption, you need to enter its password. Or let the computer access the encryption keys from an USB device before turning the computer. This unlocks the files and allows you to access them as normal.
