Understanding Common Cyber Terms

The cyber industry is still in infancy, but that has not stopped the development of cyber terminology. Even professionals within the industry can find it hard to keep up-to-date with the new developments.

 

If you would like to learn new terms or confirm your understanding of a term then please check out below. 

VPN

A Virtual Private Network (VPN) is a service that is used to protect your online privacy and your internet connection.


A VPN establishes a virtual connection from your device and hides your address information from the outside world.  This means that you will be able to use Public Wi-Fi networks safely as anyone on that network will not be able to see you.

Malicious

Malicious means the actions taken are intended to harm.

Firewall

A firewall is a security system that is implemented onto devices and networks to filter any incoming and outgoing traffic.

 

A firewall has rules that allows us to block or allow traffic into our network.  

Encryption

Encryption changes plain readable text into an unreadable format which protects the file until it has reached its destination.

Antivirus

Antivirus is a type of software that protects your devices and network by detecting malware. 

 

It scans your computer to look for known malware and if found it deletes the malware from the computer. 

Network

A network is number of devices connected together in order to communicate.  There are private networks such as the ones we have in our homes and public ones such as the internet.

Malware

Malware is a broad word that refers to any malicious software that is meant to harm or exploit any device, network or service. 

 

It's usually used by cybercriminals to extract data that they can utilise to gain financial or data advantage over their victims.

Trojan

A Trojan is a type of malicious code, programme or software that appears to be legitimate but has the ability to take control of your device. It is designed to disrupt, steal, or otherwise harm your data or network.  It attempts to trick you into running the application; once loaded, it performs the intended action.

Virus

A virus is a small programme that attempts to harm your device by gaining access to it. It has the ability to copy your personal information and slow down your device. It can replicate itself and attach itself to additional files in order to spread.
