Requesting Open Ports on the JHU Firewall

INTRO

CS does not have a network firewall in place, but JHU has a perimeter firewall in place between the Internet and JHU.

If you need a port open on the JHU Firewall, you need to request it from JHU.

Requesting JHU to Open a Firewall Port

New, Official Method

Please see:

http://it.jhu.edu/security/Public_IP_Addressing_NEW

for instructions to request port openings through the JHU Firewall.

All questions regarding the instructions need to be addressed to JHU Networking or JHU Network Security. THe JHU Helpdesk at 410-516-HELP may be able to direct your questions to the correct team.

Alternative (Older) Method If Unable To Use Above Method

All port opening/closing requests should be sent by the requester to network.security@jhmi.edu as JHU's Network Security team is responsible for the JHU perimeter firewall. You will have to provide:

a) your system's full hostname (including the domain part) and IP address.

and

b) specific reasons as to the need of each of your port openings.

and

c) allow JHU to run security scans on any equipment for which you request port openings for those IPs of yours needing port openings.

NOTE: You are welcome to CC: support@cs.jhu.edu in your request e-mail(s) to JHU Network Security, so that we can follow the conversation. But, for the most part, the conversation will be between you and JHU Network Security.
