UNIX Applications
The following applications are available on Columbia's Unix platform: cunix.cc.columbia.edu.
The Unix Standard Operating Environment (SOE) documentation details the agreed system hardening requirements and security best practices.
Beginning in Spring 2021, CUIT requires that all logins to CUNIX be verified with Duo multifactor authentication as part of our efforts to secure the University's virtual environment. For step-by-step instructions, please see our Using Duo authentication on CUNIX web page.
