Re: Personal VPN Policy Accessing University Applications

[Ken Munro <Ken.Munro () MSVU CA>]

Hi.

We don’t prohibit the use of commercial VPNs to access our services. With so many overseas/distance students, I don’t 
think it would be practical to ban them. I think it would be more work to ban them than to monitor their use, in our 
case.

It does make for a lot of false positive investigations, but it hasn’t become overwhelming for us.

We use Azure AD, so I review the impossible travel incidents in the Azure security reports and the Cloud App Security 
reports. I compare the user agent identifiers between logins from different countries. If the user agents differ, I 
will look into it. But if they are the same, then I am assuming it’s a legit user using a VPN.

I have started looking up the IP addresses from the Azure reports on Shodan. In one case, Shodan listed a slew of 
potential vulnerabilities for the server using that IP address. I emailed the student the link to our VPN webpage and 
advised him to use another one. If he continues to use that server, we might do something about that IP.

We do provide advice on our 
website<https://www.msvu.ca/campus-life/campus-services/it-services/it-security/cybersafety/vpn-tips> on how to select 
a (more) reliable/trustworthy VPN service. I am not sure that means we encourage it, but we are steering them towards 
VPNs that have a better reputation.

Cheers.

Ken Munro

I think there's a difference between inbound and outbound VPNs

Inbound - "Aw heck no!" If I find one, I'm shutting it down!

Outbound, there are a number of reasons why someone might want or need to use a VPN to reach out of the university. We 
have a number of faculty that also work for one of the local hospitals, and they need to be able to VPN into the 
hospital to access some of the things there (that they also need for clinicals)

On the student side, it gets a little bit murkier. I can use the same logic for enterprise VPNs, but the commercial 
VPNs I have a much harder time justifying, as typically those are used for bypassing monitoring, and to enable them to 
torrent copyrighted materials.

I don't know that there's a "good" answer

Subject: [SECURITY] Personal VPN Policy Accessing University Applications

Hello all,

I was just wondering how other higher-ed institutions handle users who access applications using personal VPN services 
such as Express VPN, Cyberghost, etc?  We’re seeing an overall increase in the use of these services, especially on 
mobile devices, from students.  While we appreciate the heightened awareness of privacy and security that members of 
our community are displaying by using these services, it’s also causing lots of false positives for intrusions in a 
number of our detection systems, for obvious reasons.  Right now we handle these on a case-by-case basis, but that’s 
starting to become overwhelming, and we would love to come up with a blanket policy we can socialize to our end-users. 
I’m hesitant to ban them outright, but the anonymous nature of these services makes it extremely hard to filter out 
legitimate use from malicious use.

Thanks in advance for your feedback, and thank you to everyone who participates in this list – it’s enlightening and 
educational to read all the posts whenever I have the time to check-in and catch up!

Sincerely,
