IT security

Linköping University is subject every day to attempts to steal information or commit fraud, and it nearly always starts with an email message. The purpose of this information on these pages is to arouse your interest and awareness for IT security. There are a number of simple measures that you can take to improve IT security.


Actions that co-workers can take

Problems often arise unexpectedly, and on the most unsuitable occasions. If the worst comes to the worst and your computer crashes, is stolen or becomes encrypted – do you have backup copies of your files, such that you can continue working? Spend some time reviewing how you store your files.

Some problems can be avoided by installing an antivirus program, but it is also important that you take care when downloading files and programs from the internet.

If your computer becomes infected by a virus or becomes encrypted, contact the incident response team (IRT) or Helpdesk to obtain help. You can, however, first try these ideas.
