What Is Cyber Security?


IT Governance defines cyber security as the application of technologies, processes and controls to protect systems, networks, programs, devices and data from attacks over the internet. It aims to reduce the risk of cyber-attacks and protect against the unauthorised exploitation of systems, networks and technologies.

In more simple terms, cyber security, computer security, or information technology security is the process of protecting computer systems and networks from information theft or damage to software and/or hardware. As I’m sure you have realized, this is quite an important task.

Why Cyber Security Is Important

Society today is hyper-connected. Everyone has a cell phone or computer, and we all use them every single day. Think of what might happen to you if you are the victim of a cyber-attack. You might have your identity stolen, sentimental data such as family photos may be lost, or you might have some money removed from your accounts. Sounds rough I know.

Naturally, cyber-attacks can have similar outcomes with large corporations, on a much larger scale of course. The identity of thousands of employees can be stolen, critical and classified company information can be exposed to the world, or their systems can be shut down causing a massive loss to the business and its shareholders.

No one would want this to happen to them, at least I certainly wouldn’t. That is where cyber security engineers come in. They are the silent superheroes of the tech world. They keep our data protected from weak points and allow us to use technology without any concern.

What Is a Cyber Security Engineer?

Cyber security engineers are individuals that identify threats and vulnerabilities in systems and software and then develop, implement and maintain various solutions to solve the problems and defend against hackers.

Security engineers come in many forms, such as:

  • Cyber Threat Hunter
  • Network Defender
  • Security Administrator
  • Security Operations Centre (SOC) Analyst
  • Cybersecurity Analyst
  • Incident Responder
  • Forensic Analyst
  • Security Auditor

Is Cyber Security a Good Career?

The short answer is yes. The demand for IT security engineers is growing at a rapid rate. However, there is a serious skills shortage for this sort of career. Not many people set their sights on a career in cyber. Perhaps it is a lack of awareness, or maybe a sense of intimidation? The fact is that the world needs cyber security engineers working their socks off to protect our digital data.

Starting a career in cyber can be a tricky one. Where do you start? Is there a defined starting point? If you’d like to do a short course or two just to dip your toe in the water before diving in, then a great starting point is with CompTIA certification. Specifically their Security+ certification. For those who are set on a career in cyber, a dedicated career starter programme is a great way to start.

Common Security Threats

There are many different types of cyber threats. Each security threat needs to be taken seriously and needs to be identified, monitored and resolved as soon as possible to avoid disaster.

Here are some common cyber threats:

Phishing – No, I did not make a spelling mistake with phishing. I know this sounds just like fishing and there’s a reason for this. Just as in the sport, you cast your line, wait for a fish to bite, or entice it to bite and reel it in. This form of cyber-attack works the same. The attacker will cast you some bate, be it an email or an SMS to your phone and wait for you to click on their links. Once you’ve done this, your data will be reeled in.

Malware – This is software that is created to cause damage. This can be in the form of a computer virus. For more info, check out our blog called ‘What Is Malware?

Ransomware – Ransomware is a type of malware, but it attacks/ infects networks. Usually, to demand a ransom afterward.

To conclude, cyber security is a vital task that needs to be performed to keep digital users’ information safe. Without these individuals, it would be impossible to be online and connect with our business partners, friends, or family without having our identity, money and more stolen in a flash.
