Actual work where 2 students given their post on this:Do you believe that all data should be encrypted? Many computing professionals think this is a good idea. But a small number of computing experts
Data Encryption
Encryption protects your financial details and passwords when you bank online. It protects your cell phone conversations from eavesdroppers. If we encrypt our laptop it protects the data if our computer is stolen. It protects our money and our privacy. Smartphone’s get stolen, thumb drives get lost, email passwords get brute-forced, cloud servers get breached, unwary users get phished, WiFi networks get tapped, and eventually, malicious users obtain access to your data. So encryptions are the best method to store the data.
Encryption is the science of modifying data to prevent intruders from making sense of it. When you encrypt your data, only you and anyone else holding the decryption keys will be able to unlock and read it. This means that even if an attacker gains access to your data by breaking into a server or stealing your hard drive, they will not be able to make sense of it if they don’t have the keys. Encryption is your last line of defense, the one thing that can protect your data.
Email has become one of the mediums for exchanges of all sorts. We use email to send business secrets, financial data, personal data and various kinds of sensitive information (Ben, 2017). You should obviously do everything you can to protect your email accounts, such as choosing strong passwords or enabling two-factor authentication. But in case your account does get breached, you have a few viable options to encrypt your messages and prevent hackers from seeing the contents of your messages. The same threats that can out your emails apply to the files you store in cloud services such as Google Drive and Drop box. Even the biggest services you entrust with your files can get hacked, and the sensitive files you’ve stored in the cloud can fall into the wrong hands. The most basic choice is to protect your files with a compression tool that supports encryption and password protection features, like zip, before storing them in your cloud server. Messaging apps are perhaps the most popular applications we use on our phones. But they’re not all equally secure. Some applications will encrypt your messages in transition, but not in storage, which means your data can become exposed in case of data breaches or compromised accounts. The most secure messaging apps are those that have end-to-end encryption features, making messages exclusively visible to the parties taking part in a conversation.
I think for data to be more secure it must be protected through its life cycle (Jody, 2018).
