Nexus365 Security FAQs

All data in Nexus365 apps is very secure. Everything stored in the cloud is stored in an encrypted format. Encryption increases security as all such data will need to be cracked before an intruder or someone without the correct access can read the information.

Where is my data stored in Nexus365?
Data will be stored in Microsoft's UK repositories, backed up to other European Economic Area Data Centres.
Are my emails secure in the cloud?
  • Yes. The University's Information Security Team has already performed their due diligence over Microsoft and Office 365 and confirmed that the cloud-based service meets the University's information security requirements.
  • Additional security tools are also being introduced to further improve email protection for users.
Can I use Nexus365 on an internet connection other than the Oxford network or eduroam e.g. in a cafe or on the Park & Ride? 
Yes, see the University guidelines for staying safe on the move and for ensuring that your mobile devices are secure.
Can I use email to share sensitive/confidential information?
You should not use email for this purpose unless the information is encrypted. See the University guidelines for sending confidential emails and documents.
Is two factor authentication being made available?
(Two factor authentication is an extra layer of security that requires not only a password and username but also something that is specific to them i.e. only something the user knows or has on them, for example, a piece of information only they know or something only they have to hand, like a token).
Is there backup of email in the cloud? Can the rules for this be published? 
Microsoft back up Office 365 content for disaster recovery purposes only. However, Nexus365 users are able to self-restore email items that have been deleted (from any email folder) from the Deleted Items Folder where they are held for 90 days. The deleted item is then moved to a 'Deletions' subfolder of the 'Recoverable Items' folder.  Items remain in this folder, where they are still recoverable, until they are automatically removed from it by the 30 day retention policy.
Is security enforced on mobile clients, e.g. add a PIN number.
No, this is not in scope for this project.
How secure is my data in the Nexus365 apps (Delve, Teams etc)?
All data in Nexus365 apps is very secure. Everything stored in the cloud is stored in an encrypted format. Encryption increases security as all such data will need to be cracked before an intruder or someone without the correct access can read the information.
Can I set my own SPAM scoring? 
Not currently with Nexus365. However, this is currently being assessed as part of the new Email Security product project.
Why is SharePoint staying on-premise?  Why are we not going to use Office 365 SharePoint Online? 
  • SharePoint will continue to provide an on-premise (i.e. within University buildings) secure document repository for the foreseeable future.  This will be reviewed at the appropriate point in the service lifecycle (e.g. when an upgrade is next due).
  • SharePoint has recently been upgraded to 2013 so we are reluctant to put users through another change so soon.
  • There would be much increased complexity simultaneously migrating both the email and calendaring exchange and SharePoint to a cloud service provider.
  • Retaining SharePoint on-premise addresses the regulatory requirement of some funding bodies for certain data types and data sets to be stored on premise.  Many existing such data are already stored in the University’s on-premise SharePoint system.
