In efforts to further improve the overall security of the Computer Science Department's computing resources, we will be blocking Remote Desktop(RDP) and SecureShell(SSH) at the edge of our network on the night of January 12th at 11pm. This change is intended to reduce our current attack surface, and limit the effectiveness of brute force attacks levied against our computing resources. In addition to putting these restrictions in place, we will also be migrating our VPN to our newly acquired Palo Alto firewalls. This page is intended to provide information on what can be expected after the remote access restrictions have been put in place as well as details on how to connect to the new VPN.

== Known GlobalProtect Issue on MacOS 10.13.x (High Sierra)==
 +
There is a known issue with using GlobalProtect 4.1.x on MacOS.
 +
 +
=== The Issue ===
 +
After installing the current GlobalProtect client application on MacOS High Sierra, GlobalProtect will prompt for a portal address. After entering the address, it will automatically attempt to connect to the specified address without ever prompting for credentials first, causing the connection to never complete.
 +
 +
The reason this happens is because GlobalProtect uses unsigned kernel extensions, and MacOS does not allow kernel extensions from untrusted sources.
 +
 +
=== The Fix ===
 +
To fix this issue, please follow the steps below, or send an email to root@cs.odu.edu.
 +
 +
1) Uninstall GlobalProtect using the installer
 +
 +
2) Reboot the Mac into recovery mode by pressing "Command + R" when it is powering back on
 +
 +
3) Open a terminal from the menu at the top, under the "Utilities" tab, and enter this command:
 +
 +
  $ spctl kext-consent add PXPZ95SK77
 +
 +
4) Boot regularly into MacOS
 +
 +
5) Re-install GlobalProtect

In the interest of security, Remote Desktop Protocol (RDP) and Secure SHell (SSH) connections made to our resources from outside of the campus network are blocked, with a couple exceptions noted below. Such connections can still be established by being on our VPN. This page is intended to provide information on how to connect to the VPN.

Remote Access Policy

Inbound RDP and SSH access are restricted to all resources.

RDP/ SSH connections will not be blocked if they originate anywhere on campus. Besides the caveats mentioned above, remote access to all servers/workstations will require that a connection be established to our VPN first.

VPN

Our VPN is available to Students, Faculty, and Staff. Some guest accounts are not initially granted VPN access. If such guest access is required, send an email to root@cs.odu.edu and CC the head of the research group you are associated with for confirmation.


Windows, MacOS, and Linux Users

Instructions for connecting to the VPN

Connecting Printers (MacOS)

Below is a guide for setting up connection to printers once connected through a VPN connection.
