IT security starts by protecting your PC

In this guide we will increase the protection of our equipment and avoid the most frequent security problems. For any questions, or to request assistance, you can contact us through the STIC Users Service Centre:
Online at (preferably).
Telephone 950 015 999 for external calls.
Telephone 85999 for internal calls. 

Safety standards rules

1.- Never open electronic messages of unknown origin, or attachments. 

2.- Never give out your personal data, or any type of access code

3.- Do not access questionable websites or download applications from unofficial websites. 

4.- Do not write your passwords down in any document, or share them with other users. 

5.- Short or easy to guess passwords should not be used. Do not use the same passwords in High Security Systems (Banks, University) as in less secure systems.

6.- You do not have to respond to messages that request information urgently.  The STIC or your bank will never request any personal information from you electronically. 

7.- You must have antivirus software installed on your computer. (For Administrative staff and Service personnel and Teaching and Research staff)

8.- Make backup copies frequently to avoid losing important data. You can use the "Backup and Drive Sync" client to perform the copy task automatically.

9.- Leave your PC on and connected to the network at least once a week so that during the night it can download and automatically  install the operating system, antivirus and other updates.  

10.- It is highly recommended to keep the equipment frozen (except for security updates) using the software freezing equipment provided by STIC (DeepFreeze).   (For Administrative staff and Service personnel and Teaching and Research staff)

Secure browsing

You must use your operating system  system update to fix the different vulnerabilities that are detected over time and protect you from attacks. In addition, when connecting to the Internet, it is advisable that you consider these measures:

  • Use updated versions of browsers to be protected against vulnerabilities.
  • Browse well-known websites.
  • Do not leave computers unattended while they are connected.
  • Do not accept the execution of programs which activate download without your request.
  • Do not download / execute files from questionable sites because they may contain potentially malicious code.
  • Do not accept server certificates from Web pages if your browser tells you that it does not recognise it. They may be fake pages designed to capture personal or private information.
  • Use antivirus software to check everything you download before running it on your computer.
  • Set the security level of your browser according to your preferences.
  • Check that the firewall is active.
  • Download programs from official sites to avoid malicious phishing.
  • You can use anti pop-up programs to remove annoying pop-ups that appear during navigation, or configure your browser to avoid these windows.
  • Use a user without Administrator permissions to surf the Internet, which prevents the installation of programs and changes in system values.
  • Delete cookies, temporary files and history when you use third party equipment (public or other people) to leave no trace of your browsing.
Secure browsing

To update your equipment if it is frozen, you must first defrost it, then update the software and then re-freeze it.
To freeze your equipment, you must contact the Customer Service Centre at or at 85999.
