What is cyber security?

Cyber security is about protecting your technology and information from:

  • accidental or illegal access
  • corruption
  • theft
  • damage.

You need to protect any digital information that your business creates, collects, and stores. Providing a secure system is critical to protect your business from cybercrime and maintain customer trust.

Threats to your technology or data might come from:

  • Criminals who want money or information and illegally access your hardware and data.
  • Clients you do business with who want to compromise your information.
  • Business competitors looking to gain an advantage over your business.
  • Current or former employees who accidentally or intentionally compromise your information.

Cyber criminals look for access to information and data on your business, employees and customers.

They might do this by:

  • theft or unauthorised access of hardware, computers and mobile devices
  • infecting computers with malware (such as viruses, ransomware, and spyware)
  • attacking your technology or website
  • attacking third party systems
  • spamming you with emails containing malware
  • gaining access to your information through your employees or customers.
