Encryption, We hear the term used often. Some associate it with security and protection. Others with breaches and destruction. It is at the heart of many new problems, solutions, and innovations. But what is encryption? And why can it be seen as either a good or bad thing?
Encryption is the process of converting readable data into unreadable data, only to be made readable again if decrypted with the proper decryption key. It was created to secure the transfers of sensitive data, and has its roots dating back to the enigma machines of World War II (pictured in featured image), cracked by the English computer scientist and mathematician Alan Turing. Today encryption is used to protect sensitive data such as banking information, medical records transmissions, and critical business data. But is Encryption a very secure process? And how is it done?
In a nutshell encryption scrambles up data and saves it. The only way the data can be unscrambled is if the user has a decryption key or algorithm to unscramble or decrypt the data. To demonstrate I created a small Python program with a very basic encryption algorithm to demonstrate: click here to learn more.
There are many positive ways encryption can be used. The AES encryption standard is used by the U.S. Government and many business such as Automated Business Solutions MaxxD cloud backup Services. It prevents outsiders from prying in on your personal data. This is especially effective when your data is saved on a space such as the cloud.
But there are some ways encryption can be used negatively. In the case where data is encrypted without access from the proper user such as in ransomware. Ransomware can infiltrate a computer or network through methods such as email phishing, or insecure sites. Once it infects a system it can encrypt data away from the proper user. By doing this, the virus creator can hold data ransom from a user, withholding the encryption key until a certain amount of money is sent usually via Bitcoin. The best way to secure your network from this type of malicious use of encryption would be through Automated Business Solutions MaxxP protection services, which is powered by Barracuda email filters that prevent phishing scams from ever reaching your network, And MaxxM monitoring services that provide Bitdefender Antivirus and patching services that can provide immunity from a cyber-attack via ransomware.
The last area where we see encryption technology is an area such as Bitcoin, in this area, rather than securing data from other users or accounts, the publicity of the data becomes the security of it. When transactions occur with bitcoin, an encrypted key is assigned to the owner of the coins, only the owner of the coins can decrypt them to their public key to use for transactions.
In conclusion, encryption is a powerful technology. The best way for our networks to survive in an encrypted world is to use the technology effectively.
