In this week’s blog we are looking at Cybersecurity, a very important topic. Cybersecurity is one of the hottest topics in IT at the moment as the threat from cyber-attacks is ever increasing.

This month’s Wise Words are:


Bandwidth refers to the amount of data that can be sent over a network. Measured in “bps” or bits per second, bandwidth is a bit like a road and the bits are like cars on the road. A two-lane road can’t carry much traffic and is slow. A six-lane motorway is much faster.


Broadband is a way of connecting to the internet. It allows information to be carried at high speed to your personal computer, laptop, tablet, smartphone, smart TV or other web-enabled device.

Broadband has largely replaced the original ‘dial-up’ (narrowband) method of connecting to the internet, which was much slower.

The Education sector is currently being subjected to an increasing number of ransomware attacks. The National Cyber Security Centre (NCSC) have been reporting more and more attacks on schools, colleges and universities since August 2020. They are currently investigating another increase in these attacks as of late May/June this year.

It is important that all organisations, including the education sector, understand the damaging consequences of a ransomware attack in terms of data loss and access to critical services.

What is Ransomware?

“Ransomware is a type of malware from cryptovirology that threatens to publish the victim’s personal data or perpetually block access to it unless a ransom is paid” – Wikipedia

This means that until the ransom is paid your computer is effectively useless.

How does Ransomware work?

There are multiple things that the operators of the ransomware can do to block access to your pc:

  • Diskcoder ransomware – encrypts the whole disk (hard drive) and prevents the user from accessing the operating system.
  • Screen locker – blocks the access to the device’s screen.
  • Crypto-ransomware – encrypts data stored on victim’s disk.
  • PIN locker – targets Android devices and change their access codes to lock out their users.

Things you can do to help reduce the likelihood of these attacks

  • Always be on your guard when opening emails, were you expecting this email even if it is from someone you know?
  • Never click on strange links in messages unless certain of their legitimacy.
  • Make sure you have strong passwords, do not use passwords that can be easily guessed. A passphrase is better
  • Make sure you use two Factor Authentication where you can.

If you would like some help setting up a business recovery plan and your Cybersecurity overall, call us on 01666 840531 and we can help protect both businesses and individuals be Cybersecure.

Next time… we will be talking about Networks and what the different types of networks are.
