On Thursday, January 4, 2018 starting at 12:00 am and ending by 3:00 am, Enterprise Information Technology (EIT) will be working with the vendor to resolve the issues experienced during the implementation of the Enterprise Firewalls. This is being performed under emergency change CHG0045738.

We experienced some issues with implementing the enterprise firewalls that require additional support from TAC, due to this, we initiated the roll-back. We will post further updates regarding tomorrow\'s scheduled maintenance.

Original Alert

On Wednesday, January 3, 2018, during an extended maintenance window from midnight to 7:00 a.m., Enterprise Information Technology (EIT) will be installing enterprise firewall hardware to the University Enterprise Network (UEN) in preparation for enhancing the University's overall cybersecurity.  This work will consist of adding two enterprise-class firewalls to the UEN high-availability configuration. During this maintenance window, EIT will be completing fail-over testing to verify the configuration is working as expected. Any possible outage of network connectivity outside of Penn State during this time is expected to be minimal. 


This change is being tracked via ServiceNow change number CHG0044919.


On Thursday, January 4, 2018, rulesets will be applied to the newly installed enterprise firewalls to protect Penn State wireless. A ruleset specifies what services are let through the firewall, and which ones are kept out. This change is being completed in accordance with Administrative Policy AD95 (https://policy.psu.edu/policies/ad95).


This change is being tracked via ServiceNow Change number CHG0045390.


We appreciate your patience and assistance as we work to improve security and reliability of the UEN. 

Please monitor ITS Alerts for any updates. To report an issue, contact the IT Service Desk (http://www.itservicedesk.psu.edu/).
