Share files via SFTP
SFTP (Secure File Transfer Protocol) is principally used for file sharing. In Imperial College it is commonly used as a way of collaborating with other universities and colleagues in the field who wish to exchange large amounts of data. Imperial College already has a cloud based SFTP service (through BOX), which will satisfy the majority of user’s needs. However there is a need for an on-premise solution for some cases.
These cases include organisations where Imperial College staff are in a location that blocks access to external file sharing servers/services. In addition it also makes it easier for collaboration to happen with certain sensitive locations (E.G NHS sites). There is also a number of external health data suppliers who want to use SFTP to transfer data, and require Imperial College to store the data internally (on-premise).
- All users of this service will need to have an Imperial College user account.
- Users will need to have an SFTP client to connect to this service.
- Users (both internally and externally) will need to connect to the following location to use this service SFTP.IC.AC.UK
- Typically for most users they will connect as follows, sftp [IC username]@sftp.ic.ac.uk e.g. sftp email@example.com
- After the users login they will be upload to their designated group area, where there will be a [Groupname]-incoming folder where they should place their files (or pull their files from if they are downloading it)
Other Key Points:
- Service will be resilient across two servers
- For customers, it will provide encryption in transit and encryption at rest.
- 100GB quota per group.
- 10 day retention period with automatic deletions.
- MOTD & Issue login screens to communicate with users regarding the service and also retention period.
- Auditing of access will be enabled.
- SFTP protocol only for ingress and egress of data.
