Understanding What Is Cyber Security and Reasons to Learn It

Look around today's world and you'll see that daily life is more dependent on technology than ever before. The benefits of this trend range from near-instant access to information on the Internet to the modern conveniences provided by smart home automation technology.

With so much good coming from technology, it can be hard to believe that there are potential threats lurking behind every device and platform. Despite society's rosy perception of modern advances, cyber security threats presented by modern tech are a real danger.

A steady rise in cyber-crime highlights the flaws in devices and services we've come to depend on. This concern forces us to ask what cyber security is, why it's important, and what there is to learn about it.

So, What Is Cyber Security?

Cyber security is an area that covers how to defend devices and services from electronic attacks by nefarious actors such as hackers. While there can be offensive components to cyber security, most of today's professionals focus on determining the best way to defend everything from computers and smartphones to networks and databases from attackers.

In the media, cyber security has been used as a catch-all term to describe everything from identity theft to international digital weapons. These labels are valid yet fail to capture the true nature of cyber security for those of us without a computer science degree or experience in the digital industry.

Why Is Cyber Security Important?

Today's cyber security industry is largely focused on protecting devices and systems from attackers. While the bits and bytes behind these efforts can be hard to visualize, it's much easier to consider the effects. Without cyber security professionals working tirelessly, many websites would be nearly impossible to enjoy due to ever-present denial-of-service attack attempts. Imagine not having access to Simplilearn's community of experts and certified professionals – no more tips, tricks, and advice to help you achieve your professional goals!

Worse yet, without strong cyber security defenses, it would be easy to destroy modern-day essentials like the power grids and water treatment facilities that keep the world running smoothly. In May 2019, E&E News reported that an anonymous U.S. utility became the first to report a malicious "cyber event" that disrupted grid operations, an unfortunate milestone for our country's power sector. Power generation wasn't harmed and there were no blackouts, but the impact could have been much costlier.

Simply put, cyber security is critically important because it helps to preserve the lifestyles we have come to know and enjoy.
