How to Protect and Secure Your Data in 10 Ways

How to Protect and Secure Your Data in 10 Ways

Operating systems and applications can always be reinstalled, but your data is unique, making it the most important thing on your computer or network. “Organizations must now maintain robust privacy measures, including clear privacy policies, opt-out processes, and compliance with consumer protection laws, to mitigate financial and reputational risks,” said IEEE Senior Member Kayne McGladrey in an email to TechRepublic. Here are 10 ways you can protect that data from loss and unauthorized access. 1. Protect everything with passwords Password protection is the first line of defense against unauthorized access to your data; it also helps boost multilayer security for your systems by allowing you to combine password protection with other security measures. Some businesses are required to use password protection as part of compliance regulations, such as the General Data Protection Regulation. To password protect your business data, implement a strict password policy to ensure employees create complex passwords. Additionally, you should have them update their passwords regularly. 2. Back up regularly Backing up your data early and regularly is an important component of …

Indian cryptography research gears up to face the quantum challenge

Indian cryptography research gears up to face the quantum challenge

Fundamental research in cryptography that’s used worldwide to facilitate internet banking, e-commerce services, and secure messaging systems is now taking root in India as well. The principal goal of those developing or using cryptographic systems is to improve system security. Cryptography — from the English roots of “hidden writing — is the name for techniques that secure information by converting plain text into ciphertext. It is concerned with the creation and use of encrypted messages that only the sender and the receiver can understand and which a malicious actor who interferes with the communication can’t. Sending secret messages isn’t new. Archaeologists have unearthed clay tablets made by the ancient Mesopotamians in which they wrote down cryptic formulae to make ceramic glazes. In the first century BC, the Roman dictator Julius Caesar used the eponymous Caesar cipher to relay messages of strategic value to his generals. More recently, many Polish codebreakers fled their country after Adolf Hitler invaded it in 1939 to work with reputed British mathematicians, including the father of modern computing Alan Turing, to …
