EZProxy: Vendor Block Procedures

Vendor blocks are usually reported directly to the Acquisitions department's email distribution list at liblicense@ou.edu.

Discovery Services follows this distribution list and checks it several times a day.

If a block is reported to an individual, they send it to liblicense@ou.edu, and/or directly to Discovery Services.

When a block is reported, the vendor provides the IP that has been blocked along with detailed logs of the suspicious activity.

Our EZProxy IP is 129.15.14.45. 

• When the EZProxy IP has been blocked, we review EZProxy logs and locate the offender's 4x4 and off-campus IP address.
• Once located, we block the 4x4 and the off-campus IP address on the EZProxy server.
• We create a support request with OU IT, including details about the vendor block along with the 4x4 and IP address of the user.
• OU IT forces a user password change, and asks them to reach out to the library to have their account block removed, once their password has been changed.
• We then contact the vendor and let them know what measures have been taken and ask that the block be lifted.

Sometimes, the vendor blocks a campus IP, other than the EZProxy IP.

When that happens we create a support request with OU IT, because we have no access to those logs.

Once a ticket is created, it is forwarded to Eric Zemke and Sung Chou to be assigned to the IT security team.
