Cybersecurity

Safety in the online environment is important for everyone today – whether you study, teach or work at Charles University.

You use our university systems every day – logging into SIS, reading emails, sharing documents or connecting to the Eduroam Wi-Fi network. To keep everything safe, just follow a few simple principles.

On these pages you will find advice on how to protect your account, personal data and device. Everything is explained clearly and without complicated technical language – practically and step by step.


Cybersecurity is not only about technology, but also about your everyday behaviour. With the right habits, you can prevent most problems – from forgotten passwords to misuse of personal data.


Not everything online is bad — but not everything is real. Verification helps to tell the difference.
