Encrypting & Sending Data
Before considering using any device or sending any information from the University, the content of the information to be shared must be considered. University Information can be classified as follows, according to the Information Security Policy (http://url.tees.ac.uk/isp)
Personal Information will generally fall into the Protected Category. Things such as internal telephone numbers, post titles and names are not personal information for the purpose of this scheme and would not be regarded as protected information. Personal information that would be classed as protected information would be such things as Home address, Personal phone numbers etc. and warrant a confidential classification. Bank account details, Credit Card numbers, Passwords or Medical records would most safely be classified as Highly Confidential. A dataset that contains a mix of classifications must always be handled according to the most sensitive.
Encrypt a Single File
You can encrypt a single file, a word document for example using the 7zip application that is installed across campus, there is a guide here. You should do this before sending a file via email, or using dropbox.
Sometimes USB keys come with their own inbuilt security, such as IronKeys. If you can, make use of this encryption software. If not, you can make use of the University standard software, BitLocker-to-go. There's a guide to encrypting a USB key here.
Sending large files
The University email systems can't handle large files (over 20mb) so this often presents a problem, when you need to send a large file outside of the University. To assist with sending large files, the University have implemented a service to allow you to send large files. This is called 'sendto' and is at http://sendto.tees.ac.uk. Please note, that you should encrypt any files that you send via this service.
