[U]Tech to strengthen security on two services

Effective Tuesday, July 16, University Technology ([U]Tech) will strengthen security for the computer registration for the Case Western Reserve University campus network and the [U]Tech Software Center.

Using either of these services will require TLS (Transport Layer Security, a cryptographic protocol that enables secure data exchange over a network) of 1.2 instead of the older 1.1 or 1.0. Users not running TLS 1.2 will be unable to access these items.

TLS 1.2 is supported by most modern browsers used at CWRU, but is known to be unsupported by Internet Explorer 7, and requires the following configuration change in Internet Explorer 8-10:

  1. Go to “Tools” and select “Internet Options.”
  2. Select the “Advanced” tab.
  3. Enable (by checkmarking) “TLS 1.1, TLS 1.2” and also disable (i.e. un-checkmark) “SSL 3.0” for additional security.
  4. Click “Apply” and then “OK.”
