An easy way to see if your Google Drive files are findable by others – 11/03/20

 

 

Documents in Google Drive can just be shared or shared and findable. A shared document is one that you are giving a specified person or group of people access to. If you don’t have the link to the document or the document isn’t shared exclusively with you then you can’t access it. In other words you have to specifically been given permission to see the document.

A findable document is one that anyone with an @mtroyal.ca email address can search for. All they need to do is enter a term in the search field in Google Drive and Google will find all the documents that contain that term in the filename or contents. Therefore they don’t need to have the link to access the document, they can just search for it.

Currently, the option to make a document findable is buried in the settings wheel that is only accessible when you want to generate a document link that can be used by members of the Mount Royal University group.

 

 

This makes it difficult to accidentally make a document findable. However, a few years ago this option was part of a drop down that included other sharing permissions.  This made it much easier to select it when you didn’t intend to.  The good news is, only MRU community members can search for the document. The general public cannot. So if you accidentally made the document findable, you are somewhat protected.

Now for more good news. While there is no easy way to determine which documents have been shared. There is an easy way to determine which of your documents are findable, just type owner:me source:domain in the Google Drive search bar and press Enter on your keyboard. It will bring up all the documents that you own that are marked findable. As a document can’t be findable unless it is shared with the whole campus, this should help you track down some of your accidentally shared documents and folders as well.

You are welcome!

 

Check the sharing permissions on your files stored on the Google Drive – 10/21/20

With the move to working from home, many of our business processes have changed. For example, documents that we used to save on the J: drive have had to be moved to the Google Drive to ensure everyone has access to them. However unlike the J: drive where everything saved on it is viewable only by your colleagues in your department, the Google Drive allows you to share a single file or a whole folder with anyone. To quote Winston Churchill

Where there is great power there is great responsibility…

It has come to our attention that many of you are struggling with this power. We have found there are many documents sitting in the Google Drive that are viewable by anyone with a Mount Royal email address that really shouldn’t be. Submitted student assignments, job offer letters and lecture recordings are just some of the documents that are viewable by the entire MRU community.

We appreciate that you are doing the best that you can with what you have. We have all been thrown into a working situation that none of us were expecting. In the middle of which, Google decided to change its file sharing dialog box. So even if you were familiar with how to share files, you have had to relearn it.  Throw in Shared Drives and it is no wonder so many documents are viewable by the wrong people.

If you have read this far and are thinking, “I know how to share files, I am sure that no one has access to them who shouldn’t”, please take a moment to check the sharing permissions on your files that contain sensitive information. As I said before, Google has changed their Sharing dialog box and we have oodles of sensitive documents that are viewable by the whole campus. You may think that your documents are secured, but they may not be. Don’t assume, check.

If on the other hand you have read this far and tears of frustration are streaming down your face, I come with a message of hope. File sharing is easy once you understand a few key concepts.

The Google Drive is one massive server

When you save or create a document on the Google Drive, you are placing it on a huge server that the whole world has access to. You only see the files and folders that you have been given permission to see.  By default that is all the files and folders you create. The same is true for anyone else who uses Google Drive.  So when you create or save a document to the Drive, is it unviewable by anyone except you until you share it with someone else.

A document has the same sharing permissions as its folder

When you save or create a document in a folder, it takes on the sharing permissions of the folder.  To help you keep track of which folders you have shared and which you haven’t, Google gives you a confirmation dialog box to remind you that the document you are creating in a folder will be shared.

It also gives you one when you move a document to a folder that is shared.

Unfortunately, it does not give you a reminder when you upload a file into a shared folder. How do you remember which folders are shared and which aren’t? It can be confusing. A neat little trick I use is color coding. I color all the shared folders red. That way I can quickly and easily see which folders are viewable by others and which are only viewable by me.

Any folder in the Shared with me section may be viewable by others

When someone shares a document with you, it appears in your Shared with me section of your Google Drive.

Any folders found here were not created by you. If they are shared with you, they likely are shared with other people as well. Before you create or add a file to one of these folders, check its sharing permissions so you know who will be able to access your document.

Documents in Shared Drives may be shared with people who are not members

When Shared Drives first came out, they were called Team Drives and only people who were members of the Team could access the documents. Google has updated this feature. Along with a new name, you can now share folders and files in the Shared Drive with people who are not Team Members.  Once again, this makes it challenging to determine which folders are shared with who. Unfortunately you cannot change the color of the folder icon in Shared Drives. Instead, ask all Team Members who create folders to put SHARED in the folder title if it is shared with people outside the Team.

The fewer people that have access to a document, the more secure it will be

Only share a document with the entire Mount Royal community or everyone who has a link, if that document really needs to be accessible by all those people.  There is no need to share a contact list with the whole campus when only your department needs access to it. Don’t share a recording of your lecture with the whole campus if only your students need to access it. As soon as you open up document access to a large audience, you start to loose control over its contents. Before you know it, you have people contacting you asking for more information about about a topic that they should have no knowledge of.  Keep your documents secured, only share them with those who absolutely must access them.

I hope that this information has cleared up some of the confusion around safely sharing files on Google Drive. For details on how to share files, visit the Google Drive Help webpage.

 

How to avoid having your Google meeting bombed – 04/22/20

 

 

Although Google Meet is a more secure platform than Zoom. It isn’t immune to meeting bombers. This week, an MRU employee had a rather disturbing and unfortunate experience with one of their Google meetings.

As the meeting organizer, they followed a registration process that had been established for their department’s meetings to ensure that all attendees were legitimate. However as this is a new platform and there are special circumstances that arise, they knew that there would be individuals signing in who would not be on the registration list. So when they received a request to join the meeting they were not concerned. That is until they attempted to verify the attendees identity and were rewarded with profanity.

The organizer of the meeting removed the trolling attendee. However there were several other attempts by this same individual to join the meeting again.  In their brief time as an attendee, they had a grabbed a list of other attendees. They then impersonated one of them and repeatedly asked to join. The poor organizer had to keep asking the impersonated attendees if they were attempting to join using another email address.  The whole incident was very disruptive. The organizer handled things very well but wanted to know how to prevent this from happening in the future.

There are a few things that you can do. First if you are using nicknames for your meeting, avoid using common meeting names.  Team meeting, department meeting and math class are examples of nicknames to avoid. This prevents trolls from finding your meeting simply by entering nicknames that are commonly used. Second, if at all possible don’t post meeting links in a public location. Try to limit it to meeting invites if you can. Third, simply deny join requests. Join requests are only required if the attendee isn’t using a Mount Royal email account.  Let your attendees know that they must use their Mount Royal email address to join your Google meetings and you will avoid this problem all together.

If however you are meeting with people outside of the Mount Royal community, then you will have to rely on the other two measures to keep trolls from bombing your meeting. If you are  having meetings of this nature regularly, contact the IT Service Desk to see if another video conferencing solution is available for you to use.

Only you can use your MRU account – 02/26/20

 

 

When we tabulated our survey results, we were delighted to find a significant reduction in password sharing on campus. However, our victory lap did not last long. Password sharing is happening less but there are scary numbers of people logging in and letting someone else use their account.

We understand that you have guests that come on campus and need wifi access, that you have new employees that you need to train and that sometimes a colleague’s or friend’s account isn’t working.  However regardless of the reason, credentials should not be shared.   Your credentials are only for your use. They give you exactly what you need to have access to, no more and no less.  This protects you, your colleagues and the institution.

Stop for a minute and think about all the things only you can access with your login credentials that no one else has access to. Do you really want someone else to be able to access those things? Think about how embarrassing, uncomfortable or alarmed you would feel if a colleague or friend started exploring. I know what you are thinking, I can trust them. They wouldn’t do anything malicious with my account.

Regularly we hear about horror stories of friendships gone wrong, bitter colleagues, bad breakups and the resulting fallout.  When things go bad it is impossible to predict how someone will react. You would be unpleasantly surprised to know the damage that has been caused when these things occur.

Even if letting someone else use your account doesn’t result in data armageddon,  it is against the Acceptable Use of Computing and Communication Resources Policy. The good news is there is no reason to do so. IT Services can arrange access for anyone for any reason. We have a solution for every situation.  Find yours in the Credential Use Guidelines. If you aren’t sure what to do, just call the IT Service Desk and let them know what your time frame is. They will get back to you right away and provide you with a solution.

Don’t give up control by logging in for someone else. Reserve your account for your use only.

 

 

Someone with your name could hurt your job prospects – 01/31/19

With Data Privacy Day disappearing in the sunset, the calls encouraging you to check your online footprint are also fading. However with many of last semesters graduates hard at work trying to land their very first grown up job, I would like to revive the call. This time I want to add an extra tip, also check out the online footprint of those who share your name.

This little extra bit of advice comes from the experiences of a Mount Royal University employee. She had her new boss tell her to correct her education details on her Facebook page, insisting she had listed the wrong university. Here is the deal, they had looked at the wrong profile. Her information was correct. They had looked at another person’s profile who vaguely looked like her and had similar education. Fortunately, the owner of this other profile had posted information that any employer would be happy with. Our Mount Royal employee was lucky.  It could have gone very badly.

The best way to check your online footprint is to grab a public computer, don’t login and then google yourself. Then check out all the people on the first three pages (most employers don’t have the time to look further) of search results.  If you find someone else with a less than desirable profile that you could be confused with, include a notification of this on your resume. If something is showing up that you want kept private, change your privacy settings for that account or ask the account provider to remove the material.  The last thing you want is to end up like this guy.

 

 

Apps sending Facebook your data even if you aren’t a user – 01/07/19

 

 

It is reasonable to think that if you don’t have a Facebook account, don’t view their web page or otherwise engage with any of their content that they wouldn’t have access to your personal information.  Think again.  Privacy International just completed an investigation that shows Facebook is routinely tracking users, logged out users and non-users.  That’s right, even if you have not signed up with the blue devil you are still being tracked.

They tested a variety of Android apps and found that at least 61 percent of them transfer data to Facebook the instant the user opens them. This holds true regardless of whether the user has a Facebook account, has opted out of receiving Facebook cookies or is logged onto Facebook. How much data is transferred and the nature of that data depends on the app.  Some simply do a quick check in while others continue to send data as the app is used.

The data is transmitted through Facebook’s SDK (software developer kit) which allows a developer to create an app that  interacts with Facebook. This cool tool also lets users login to an app using their Facebook ID. Spotify, Kayak, Duolingo, Indeed Job Search, Yelp and TripAdvisor were just some of the apps implicated.  As you can see by the list, this problem is not limited to obscure hardly used apps. Many well known apps that you thought you could trust are actually spying on you.

What are you supposed to do with this information? Be aware that if you are using a web based application  or smartphone app that gives you the option of logging in using your Facebook ID, your data may be sent to Facebook even if you don’t have an account. If you want to know how much of your data is being transferred, feel free to contact the developer and ask. With the new privacy regulations coming into effect across the globe, they may actually answer. Once you know what you are giving up, you can decide on whether the data lost is worth the convenience gained.

 

Buying tech this Christmas? Check out its creepy factor – 11/20/18

 

 

This year, there are tons of cool tech gadgets on the market. Everything from teddy bears that connect to the internet to personal alarms. As neat as all of these devices are, some of them have the potential to leave the users feeling exposed and violated.

Thankfully, the good folks at Mozilla have put together a terrific website that examines the privacy risks of the hottest tech gifts. At privacy not included you can find out what information a device collects, what is done with that data and what kind of security the device has. They also rate customer service. To make it extra fun, consumers can give each item a creepiness rating based on how comfortable they would be having that device in their home.  Check it out.
