IT security in day-to-day work

Lock equipment, and use secure passwords

  • Keep your mobile and computer close at hand. Lock them if you leave them unattended for a short period, and never leave them unattended in public. An automatic lock of the screen is activated on your devices, and set it to require a password to unlock after 15 minutes on your computer.
  • Do not pass on your computer password or mobile pincode to anyone else, not even your immediate superior or a colleague. Personnel from the IT Division should not ask you for your password either.
  • Use strong passwords and change your password if you believe that it has come into unauthorised hands. See the tips here for creating more secure passwords.

Report suspect activity and think before you click

  • Report any suspect activity and spam that you receive to spam@liu.se. More information about the information you should submit.
  • Think before you click! This is true both for links and attached files and links that arrive by email, and when surfing.
  • Our spam filters catch a great deal of material, but you should even so be on the watch against email-based fraud. Be careful with messages from unknown senders and consider carefully before opening attached files. You should also be on the watch for unusual behaviour by known senders. It is common that a fraudster will impersonate a colleague or manager at LiU.
  • Attempted fraud is common by email, but you should also be cautious when you see unusual behaviour on, for example, the telephone or Facebook Messenger.

Be restrictive when using unknown WiFi networks

  • Rather than connecting to an unknown network, check whether you are in the vicinity of an Eduroam network. You can connect to Eduroam at many places in the world – at universities and other institutions of higher education, and at certain railway stations and airports.
  • An alternative to connecting to a WiFi network is to use your telephone as a modem. This can be done if you activate internet sharing. Instructions for Iphone and Android. Avoid having internet sharing activated when you are on campus.

Safe storage of files

  • Store your files in a cloud-based service (OneDrive), on “fillagret” (network file storage) at LiU, or locally on your computer. If you save your files locally on your computer, you are responsible yourself for ensuring that they are continuously backed-up.
  • Use the cloud-based service with which LiU has an agreement for file storage. At present, this is OneDrive. LiU does not have an agreement that includes data protection with services such as Box, Dropbox and iCloud.

Keep your software updated and do not connect unknown units

  • Never connect an unknown USB or other unknown external unit to your computer. These may be infected with viruses that spread automatically when the unit is connected. Read about an experiment using discarded USB memory sticks at the University of Illinois.
  • Keep your software updated and use the most recent versions, since safety updates are continuously distributed. Hackers often use safety loopholes that may be present in programs without the latest updates. Install software using MinIT, in order to ensure that it is authentic and has been vetted for safety.
  • If you connect private equipment to the LiU network, you must maintain this equipment such that it does not constitute a threat to LiU’s IT security. The operating system, for example, and all software must be kept updated, and the computer must have up-to-date protection against malware.
