The Importance Of Cyber Security

What Is Cyber Security?

Cyber security is applying technologies, controls, and processes to protect online systems, networks, programs, devices, and personal data from cyber threats and attacks. Cyber security helps to diminish the risk of cyber-attacks and defend against the illegitimate exploitation of online systems and networks.

Cyber security is extremely important due to the amount of protection it provides for a wide range of potential dangers such as theft and damage. So much personally identifiable information is stored online now, such as health and financial information.

There are also many important government documents that are stored online which need extreme cyber security as the documents are often highly confidential. Russel Haworth covered more on this in an article review he wrote about Cybersecurity in 2020.

Types of Cyber Security

There are various different forms of cyber security, and each type of cyber security works differently, although they are all highly effective.

Critical Infrastructure Security

This technique is used to defend the systems that have the critical infrastructure. Some systems are heavily relied on by societies, these systems include things like the electricity grid, traffic lights, and hospitals. Although a lot of people wouldn’t think that these systems were at risk of cyber attacks, they often act as platforms where malware can affect the endpoints of the systems that they are connected to.

In order to combat the opportunity for cyber attacks, organisers that are in charge of maintaining critical infrastructure, must be able to easily access the susceptible points for the company that they are accountable for.

Network Security

Network security helps to protect and prevent intrusions with malicious intent into an online network. Network security focuses on how different devices interact with one another, and the connections between them.

Network security is put into place by the tools you install to stop others from accessing your devices and networks. These tools and tasks that you can put into place to enhance your network security are things such as encryption, firewalls and antivirus programmes.

Cloud Security

Cloud security is the practice of shielding cloud computing environments and any information or data stored on the cloud. Cloud security helps to stop those without permission from gaining access to the cloud environment.

There are three primary types of cloud environments, the first of which being public cloud services. This environment is hosted by third-party cloud service providers, such as organisations like Amazon Web Services or Google Cloud. This environment is typically accessible through web browsers, which means that the best security methods are authentication and access controls.

Another one of the primary types of environments is private clouds, this means that they are generally only accessible to the individual organisation. Despite this, they are still very much vulnerable to security breaches.

Hybrid clouds is the third primary type of cloud environments, this is a combination of both public and private clouds. This means that organisations have more control over their personal data and resources, but they can still reap the benefits of the public cloud when necessary.

Internet Of Things Security

Internet of Things security means that you are securing Internet of Things devices and any networks that they are connected to. The devices can range from industrial machines to personal devices. Implementing IoT into businesses can be difficult due to the threat it sends to security, however, by implementing IoT security, businesses can see useful analytics, legacy embedded systems, and more importantly a secure network.

Application Security

Application security is the process of fixing and enhancing the security of apps, which makes them safer. This typically takes place during the development of the app. However, this also includes various different tools and methods that can be used to keep the apps secure after they have been launched.

This is becoming increasingly important due to the rise in ransomware that we have seen in recent years. Application security overrides potential cyber attacks as it deploys the tools and methods that were created during the development phases. There are hundreds of methods and tools that have been associated with application security, some of the main methods are anti-virus programmes, firewalls, and encryption programmes.

Types Of Cyber Attacks

There are lots of different methods that hackers use to carry out cyber attacks in order for them to achieve their goals, whether that means stealing information or passing along a virus. These are some of the most common cyber threats.


Malware is software that has been designed with the pure intention of damaging or corrupting a system.


Phishing uses emails as its place of attack. It typically includes tricking the recipient of the email into sharing private personal information or opening a link which contains malware.


This is when a hacker gets into a system and encrypts data, they then demand that the owner of the data pays a ransom in order ro get their data back. The worst case of this happened in America in 2018 and caused the whole of Atlanta to shut down.


To conclude, cyber security is becoming increasingly important – especially because of the way more and more businesses are going online and the way that technology is rapidly evolving. Keeping yourself and your clients data safe is essential to business and the best way to do this is by ensuring the cyber security you have in place is of the highest standard.
