Implementation of Inbound Default-Deny rule set on Enterprise Firewalls

All students, faculty, staff at all Penn State locations.

Internal Applications that are accessed outside the Penn State Network may be unavailable during and after firewall maintenance

The maintenance will take place from 5:00 AM ET on 08/08/2018 until 7:00 AM ET on 08/08/2018. Some internal applications may be affected during and after the maintenance.

If an internal application is impacted, you may receive error messages such as “connection timed out”, “unable to connect”, “oops, something went wrong” or “connection unsuccessful”. The impact would only affect those attempting to access these applications from outside the Penn State network. If you are experiencing issues, please try utilizing a Penn State VPN connection to access blocked applications. Traffic that originates from Penn State networks and is destined toward the Internet will not be affected.

To increase cyber-security at Penn State and to ensure the reliability of the University’s network, Enterprise IT and the Office of Information Security will apply additional firewall security policies in July and August. This is the fourth of those changes. A list of permitted applications has been developed from traffic observed passing through the firewall over the last few months. Substantial effort has been taken to identify and allow existing applications. All other traffic inbound from the Internet will be default denied after the completion of this change.

This alert will be updated as new information becomes available. Penn State IT users can view additional details in ServiceNow.

RECORD #: CHG0052590

Service may be affected during the EIT maintenance window (5:00-7:00am) on August 8, 2018.
