CBS-Secure is the Business School's preferred wireless network available exclusively for all Columbia Business School (CBS) students, faculty, and staff. It provides encryption for all network traffic and access to CBS resources unlike CBS-Guest, which is an open network reserved for our non-CBS affiliated guests.

CBS students at the Morningside campus have the option of connecting multiple personal devices

• Tablets
• Smartphones
• Laptops (Personal or Corporate)

using high-speed wired ethernet or wireless supported by the Information Technology Group (ITG) and Columbia University Information Technology (CUIT).

By the numbers

you can connect multiple devices to CBS-Secure simultaneously

wireless networks; CBS-Secure provides secure and encrypted wireless access, meanwhile CBS-Guest provides open unauthenticated wireless access for our non-CBS affiliated guests.

you only need to login to CBS-Secure once with your Lifetime ID (FLastname19) and Business School password. Your saved credentials will allow seamless wireless access each time you're in the Business School (changes to your device configuration may occasionally require you to re-enter your credentials).

With over 1,800 wired ethernet jacks and two wireless networks, Columbia Business School (CBS) offers secure and high-speed network access in our two Business School locations on the Morningside campus; Uris Hall and Warren Hall (1st through 4th floors).

Wired or wireless network access throughout the rest of the Morningside campus is available through CUIT. Similarly to CBS-Guest, the University hosts the Columbia University wireless network for un-authenticated use, and the CU-Secure wireless network for authenticated use after prior configuration.
