Information Security for students

 Your password is your most important protection against misuse of your data and identity – make sure that you create a strong password and do never disclose it to others.


At SDU, a password must meet the following complexity requirements:
1. password have at least 12 (twelve) characters
2. password includes capital letters and lower-case letters
3. password includes numbers
4. password includes special characters (like # ¤ % &)

However, it may be difficult to memorise a long string of characters and numbers. Therefore, you can work out a mnemonic rule while creating you password. Since the the following example is displayed on this website page, you should of course not use this in practice:

You can memorise this by means of the phrase:
You are born to be late

Remember to always use a password on your smartphone and other mobile devices.

Always lock or logout when you leave your computer.

A screen saver improves security

Set your computer to lock automatically after a period of inactivity. Contact you IT department if you need assistance to do so.


Antivirus software prevents vira from infecting your devices. Please be sure to be updated with the latest virus signatures.


Always make backup copies of your documents. Save your documents to multiple locations - in that way you are not so vulnerable.


Please respect the fact that locked doors are locked for a reason.

An e-mail isn't always just a common and harmless e-mail. E-mails may contain attached files and links, which you should not open or view. Your best defense is healthy scepticism.
