Going off and getting back on the network
Health Information Technology & Services (HITS) ensures that data and devices are kept secure through daily maintenance that runs in the background on employee workstations. Maintenance ensures that the latest system updates and patches are in place whenever a user logs in to the Michigan Medicine network by wire or using a wireless connection.
If you work at home or off-site with a Core laptop, chances are you “remote in” using the Cisco AnyConnect VPN network and Duo for two-factor authentication — yet another safeguard. Remote access into the network with VPN also certifies that these maintenance updates are implemented.
But what happens if your device stays off the network for an extended period of time because of vacation, an extended medical leave or some other reason? If your device doesn’t connect to the Michigan Medicine network and run the system updates and patches, it becomes vulnerable to security risks.
Connecting to the network is a two-way communication process, so not only is your data at risk, but malware can be introduced to the entire Michigan Medicine network if the operating system or applications on your device are not kept up-to-date.
New HITS policy in effect Aug. 16
In an effort to mitigate these risks, HITS will be implementing a network information assurance policy. Effective Aug. 16, if a device has been off the network for thirty days or more, it will be blocked from accessing any internal resources. You will need to contact the HITS Service Desk or your Device Support representative to have access re-established. The screen below will appear to notify you that your device cannot connect.
Before you leave — What you can do to stay connected
If you plan to go on sabbatical, have a medical leave of absence or plan to travel for an extended period of time, here are some steps you can take to safeguard your data and devices and remain connected:
- If you are traveling, see the various resources on the Traveling Safely with Technology website. It includes information on enrolling in Duo in order to use a VPN connection.
- If you are traveling abroad, consider registering your travel with the U-M travel registry.
- If you are on an extended medical leave, be sure to contact Work Connections who will assist you with managing your leave and returning to work.
- If you know that your device will not be able to be on the network for at least thirty days, notify your supervisor.
While you are away — How to keep your system healthy
- CoreImage (Windows) devices: While you are away, you should try to connect to the VPN and run maintenance (How to run Maintenance) at least once every 14 days. If you unable to run maintenance within a month, your device will be blocked from accessing the internal Michigan Medicine network; however, your VPN connection and access to external networks will continue to function as before.
- CoreMac and mobile devices: HITS-supported CoreMacs have AirWatch installed. So do institutionally-owned mobile devices. With AirWatch, your devices will be identified and able to reconnect if offline for more than 30 days.
