The Basics of Security

As hackers, scammers and basics of security become more sophisticated, so must the defenses against them. That’s why it’s so important to stay on top of the latest developments. A good way to do this is to read online news and blogs that focus on cybersecurity. It’s also a good idea to follow cybersecurity experts on social media.

While the basics of security may seem simple, they’re not always easy to understand. For example, there’s a difference between network security and cybersecurity, but the two are interrelated. Network security includes things like firewalls and networks analytics tools. It’s a subset of cybersecurity, which is more broadly defined as securing information systems and the data they contain.

In order to keep systems and data secure, there are many different technologies and techniques that must be implemented. A couple of these include multi-factor authentication and securing the network through segmentation. Multi-factor authentication involves requiring that users present credentials from two out of three categories (something you know, something you have and something you are) in order to access a system. Network segmentation separates a network into different sections or subnetworks, so that if one part of the system is infiltrated, the other parts remain unaffected.

Another essential element of information security is encryption, which scrambles data into an unrecognizable format. This protects files on a computer hard drive, a banking session or sensitive email. There are several types of cryptography, including symmetric and asymmetric.
