Two-Factor Authentication at the Lorentz Institute Introduction After the recent increase in cracker activity and floods of phishing emails (cyber criminalilty), it is clear that the Lorentz Institute IT infrastructure is under constant attack. One of the major deficiencies in our current setup is that knowing a username and password is enough to get access to a wide variety of resources and data on our servers. When phishing e-mails are handled improperly, but also when users improperly dis…

2FA Setup via a FIDO2 Security Key Introduction FIDO2 security keys offer a safer alternative to the combo credentials/TOTP. With a security key (SK), you will substitute the TOTP authentication step with public key cryptography. If you register your SK with the IL, you basically create a private-public keypair (known as a credential) and store the private key in your SK while sending the public key and a randomly generated credential ID to the IL system for storage. Upon logging in, the IL s…

Leaving the Lorentz Institute From the date your appointment ends at the Lorentz Institute there is a six-month period in which your credentials can still be used to access the workstations, your email, and the Xmaris cluster if you were granted access. This is done to facilitate any data transfers and backups that you might still want to do before leaving the Institute.
