File Sharing Tools Included in Office 365
The two file sharing systems in Office 365 are SharePoint Online and OneDrive, and they work in concert with each other to provide the total file sharing functionality of the arrangement.
If y'all desire to think of OneDrive as the backend storage and SharePoint as the frontend interface, you wouldn't be too far off. That is a good plenty manner to imagine how the arrangement works.
For example, if y'all send a sharing link from your OneDrive folder, the URL is a link to SharePoint Online.
Non disruptive at all, am I right? Let'southward wait at the major functionality of each of these systems and see what's included in OneDrive and what's included in SharePoint.
Office 365 File Sharing Basics
Here are some of the bones workflows you lot will follow to admission and share files in SharePoint Online and OneDrive.
How to Observe Files
You might have OneDrive available as an selection in Windows Explorer where you can run into the sync status, modified date, and employ the Find field to locate your files.
Yous can also use the OneDrive website to see the same information.
And you tin can meet the same binder in Teams.
How to Co-author Files
To co-writer a file y'all demand to have permissions to edit the file. You can have permissions through group membership, or the data owner could transport you a link to edit the file.
You tin share files with one or more than users, with anyone with the link, or you could relieve the file to a folder that your team tin can access.
Once you can co-author the file, you demand to open the file online in a browser or the client on your estimator (i.eastward., Word Online or Word).
Updating and Syncing Files
Updating and syncing files is usually straightforward in Office 365. When you salvage a file that you lot are working on, it will sync to the server and tell you if there are changes you don't accept in your copy. If y'all save a file to your local OneDrive folder on your laptop the files will get uploaded and synced behind the scenes, assuming you take an cyberspace connection.
It's best practice to make sure you have the virtually recent changes before you start editing once again. I've made that mistake on more than one occasion. One fashion to avert that problem is to utilise Word Online when you lot are editing. If you lot use the local copy of the file in Word, you aren't looking at the file "live."
How to Share Files on Office 365
This department covers what you demand to know about file sharing as well every bit some extra Office 365 file sharing tips.
Internal File Sharing
Internal file sharing is when you share files within the network to other users that are in the same Azure Active Directory (Ad) domain with you lot with non-guest permissions. In Office 365, you can share files from your personal OneDrive or save them to your SharePoint Team Site.
Configuring Internal Sharing
SharePoint automatically creates a Team Site when you create a group in the Office 365 Admin Center. Employ this Team Site to save documents for collaboration within your team. Role 365 creates a OneDrive binder for each user account that users should employ for personal files that don't require collaboration.
How to Share Files Internally
All yous demand to practice to share files internally is salve them to your SharePoint Teams folder. Yous can access this folder from the SharePoint website or in your Teams customer.
You tin as well send users a link to the file you lot desire to share.
- Select the option to share with Specific People, People in your organization, or People with existing admission. Use the first to specify one or few people, the 2d to allow anyone in your entire company, and the last to anyone who already has access to the file – like your team.
- Click the button to allow editing if needed.
- Allow or block download. You might employ block download on a sensitive file to make sure there aren't extra copies of that file floating effectually.
- Type the proper noun of the person(s) you desire to exist able to run into the file.
- Click "Re-create Link"
- Send the link
External File Sharing
External file sharing in Office 365 is when you demand to send a file exterior of your organization to a person that is not function of your company. External sharing is riskier because you are opening a window to your SharePoint server or potentially sending sensitive data outside of your network.
There are numerous legitimate business organization reasons to let external file sharing. Users demand to work with partners or customers. Your finance team needs to send documentation to governing bodies. Hr needs to send offer letters. You get the thought. You have to exist able to share files.
There are several ways to configure external sharing in Office 365. Let's expect at a few options.
Configuring External Sharing
Administrators can enable external sharing from iv dissimilar applications in Office 365.
- SharePoint Online
- OneDrive for Business
- Microsoft Teams
- Role 365 Groups
One pick you have is to enable invitee access, and grant external users guest access rights so they can collaborate with your internal resources the same way they would interact inside their team.
Guests are actual users in your Azure AD. Grouping owners are the gatekeepers in this case. Grouping owners tin can grant guests access to Teams conversations, to SharePoint sites, or information.
SharePoint administrators have four different options of sharing they tin can enable:
- No external sharing – prevents internal users from sharing any content externally
- Authenticated: Existing guests – allows sharing with users in your Azure Advert, y'all accept to add them to Azure Ad before they can admission data
- Authenticated: New and existing guests – allows sharing with any user authenticated to any Part 365 or Microsoft business relationship. Guests that aren't in Azure Advertisement get added as guests.
- Anonymous sharing – anyone can share via a link
How to Share Files Externally
Sharing files externally is exactly the aforementioned process as sharing them internally. You create a share link, grant the external user access to edit the file or not, and send them the link. They click the link and open up the file in their browser.
Office 365 File Sharing Security Best Practices
Here are the pinnacle 6 best practices you lot can implement to keep your data prophylactic and accessible in Office 365.
1. Require Multi-Factor Authentication
Multi-cistron authentication (MFA) is a pretty basic protection method in 2019 and a common cybersecurity tip only notwithstanding worth mentioning in a list of Function 365 file sharing and security best practices. MFA helps you verify that your users are who they say they are, but it is by no means foolproof.
Check out our Office 365 Man-in-the-middle attack, where nosotros show you how attackers can apace work effectually MFA.
2. Enforce Least Privileged Access to SharePoint Online
The principle of least privilege says that each user only gets the minimum access they need to practice their job. Getting your Office 365 permissions to a least privileged land will get a long manner to keeping your data safety.
Organize user accounts in your visitor into groups of similar task functions (e.g., IT, Hr, Finance, Dev, etc.) and those groups are granted permissions to admission their information in Office 365.
Exercise not allow individual user accounts on access command lists (ACL) in Role 365.
Assign a Data Possessor, or in this case, a "Grouping Possessor," for each group who's responsible for approval new group members and audits the group on a regular schedule. The Group Possessor is the gatekeeper of their group membership and therefore, their data.
Deny all not-grouping members any access to information via ACLs. Don't use Limited Access or View Just permissions. Non-members have to request admission from a grouping member using the file sharing rules. Create separate Public SharePoint sites for public-facing documents. Proceed Public sites separate from your Team sites.
iii. Classify Sensitive Data that lives in SharePoint Online
You demand to browse and identify the data in Office 365 for PII, HIPAA, GDPR, CCPA, intellectual belongings, and anything else that could cause either a fine or competitive disadvantage.
Once you take tagged the files correctly, y'all can make certain they are non over-permissive (see To the lowest degree Privilege above) and tagged or labeled so other security tools can also identify the data as sensitive and treat information technology appropriately. For example, encrypt sensitive files, and fix a rule to prevent the file from download to unmanaged devices.
4. Prevent Download to Unmanaged Devices
Speaking of, you need to continue your Squad data in business firm as much every bit possible. One manner to do this is to forbid any download of information to devices that your IT team doesn't manage. If you have the appropriate authority, viewing the data in a browser from an unmanaged system is OK – if yous have the link and blessing of the Group Owner.
five. Limit and Audit External Sharing
OK, this is the big 1 – and the penultimate best practise in this commodity.
Yous need to practice what you tin can to limit the exposure of your information to the exterior world, merely rest that demand with the needs of your users to share and collaborate internally and externally. Hither are a few different ways you can do both.
In Office 365, users can create a sharing link that they will send to other users so they can see the same document. When users create sharing links, they might grant anyone with the link permission to admission the file. Those links can become stolen, intercepted, or potentially brute-forced to allow access to those files — or folders if users create links at that level.
So there are a few things yous should practise to keep your information as condom equally possible.
First, prevent users from creating binder-sharing links that add access to multiple files, either externally or internally. If a user needs to admission files owned by another grouping, they should request access from the Group Owner. External sharing is only available for not-sensitive files. If you need to share sensitive files to 3rd parties, add together them equally Guests in your Azure AD, and grant them appropriate admission that way. Because they are guests and listed in the Grouping membership, the Group Owners will audit the listing and remove whatsoever extra users when advisable.
Next, set all user-created links to expire later a few days to a week. While this means that your users might have to generate more than one link to collaborate on a file, it also means that the number of links to your data doesn't grow infinitely. If those links expire organically, you lot effectively remove gamble of infiltration continuously.

vi. Monitor SharePoint Online for Shenanigans
Lastly, monitor Office 365 for whatever potential data breaches or other shenanigans that internal or external bad actors perpetrate on your system. Runway file and folder activeness, group membership changes, admin activity, and more. Correlate network traffic with that monitored data to discover possible cyberattacks in progress.
