10 dos and don’ts to improve IT security

We don’t need to tell you how important IT security is. You are bombarded with news of data breaches, ransomware, data loss and new viruses daily. We recently had the Petya/NotPetya do the rounds and even more businesses were affected with the WannaCry ransomware virus.

Keeping your software programs and applications up to date is one key way to reduce your risk. Here are some more Dos and Don’ts to help improve IT security, compliments of Sophos – a Trilogy partner.


  1. Lock your computer and phone when not in use
  2. Stay alert and report suspicious activity
  3. Password protect sensitive files and devices such as USB and phone
  4. Use long, hard-to-guess passwords and always use different passwords for different applications
  5. Beware of and report suspicious emails

Improve IT security


  1. Be tricked into giving information away
  2. Use an unprotected computer such as in an internet café, to carry out banking or other services where you must input confidential information
  3. Leave sensitive information lying around (including login and password details)
  4. Plug in personal USBs or other devices to your work pc without permission from IT department
  5. Install unauthorised programs in work

As Sophos says at the end of their handbook:

“If something looks too good to be true, it probably is.”
