What is encryption?
Encryption is the process of changing information in such a way as to make it unreadable by anyone except those possessing special “key” The special “key” allows them to change the information back to its original, readable form.
There are many types of encryptions but most importantly is to encrypt your data and the encryption of communication lines are as important
Why is it important?
Encryption is important because it allows you to securely protect data that you don't want anyone else to see. Businesses use it to protect corporate and trade secrets, governments use it to secure classified information, and many individuals use it to protect personal information to guard against things like identity theft. Encryption is used to securely protect folder contents, which could contain emails, medical history, tax information, credit card numbers, or any other sensitive information. This way, even if your computer is stolen that data is safe. It is also a requirement for GDPR and POPIA and other legislation and regulatory requirement.
What is Line Encryption?
All communication is sent over some or other communication line, Fibre link or radio wave i.e. Mobile networks, radio transmitters and the normal telco infrastructure. Due to advanced technology, hackers can intercept these communications through different methods whether it is data or voice. Line encryptions are created to secure all communications that are used over any “Copper or Fibre link or data line” to be encrypted and the information cannot be accessed or intercepted without the proper “key” to decrypt the message at the other end of the line.
Why is this important?
It is important to encrypt sensitive data including voice calls. Many companies confirm your credentials over a telephone call to ensure that they do not speak to an imposter and discuss sensitive information. Nothing stops scammers to hack the communication lines and get your personal information which can be used for financial gain through identity theft etc. Hacking communication lines is another way for espionage on both companies as well as countries but it is often neglected in considering risks within an organization.
