How we protect our networks and servers

Denna sida på svenska

Karolinska Institutet is using a web filter in order to secure our networks and servers from malware, such as viruses and trojans. This means that some websites cannot be reached when using the KI network.

KI is regularly exposed to cyber attacks which means that we risk losing valuable information, such as integrity protected data and research data. The web filter is a security measure in order order to secure that no third party can access our data or that our systems are infected with malware.

The web fitler blocks:

  • sites that contain malware (viruses, trojans, ransomware etc.)
  • high risk classified sites (as they spread viruses, have been hacked, are used for SPAM etc.)
  • sites containing different types of attempted fraud (e.g. Phishing)
  • sites selling illegal drugs
  • sites with pornographic content

Note that the filter will not block search words but only websites according to the above.

Why are these pages beeing blocked?

The web filter bloces sites according to the list above, as it entails a risk to your computer and KI's IT systems to visit those sites.

On BrightCloud's site you can look up why specific sites are being blocked.

Exception from the web filter

If you for your research need to access sites that are blocked by the filter, you can apply for an exception. The exception has to be approved by the Head of Department at your department. Then you can send the form to the IT Office. We will assess which technical solution will work best for you.
