Recommended Action

  • Frequently monitor and review security updates for all of your systems and devices. Implement security patches as soon as practicable. Set your devices to update automatically wherever possible.
  • If using a Microsoft computer, it should display a notification to update but if it doesn't you can 'check for updates' in the search bar next to the start button. Your organisation may implement security updates automatically but you may be asked to restart your computer in order to complete the update(s).

  • It is good practise to back up your system and/or important files before installing any major updates.

  • Take a look at the ‘5 Steps to Cyber Security’ guidance on our Advice & Guidance page for more guidance on how to better protect your organisation.
