Further Details

Network Security

The user is responsible for maintaining the security of their personal computers and any other device connected to the network. Critical security updates must be applied to all software in a timely fashion.

Users of Microsoft Windows are required to have anti-virus software running on their computers at all times and to apply all updates in a timely fashion.

The use of any computer system within Trinity Hall for unauthorised access to ANY other computer systems or networks is illegal and strictly prohibited.

Your network access may be suspended at the discretion of the College IT Department if your computer is found to be interfering with the normal operation of the network or is a potential security risk. Repeated security violations with no corrective action by the user will incur an administrative charge.

Data Traffic Usage on the Trinity Hall Network

The College provides and maintains the physical network infrastructure and pays for the network data traffic over our link to the Cambridge University Data Network (CUDN). Students are charged a fixed termly fee to cover this cost.

Additional usage charges will be incurred to students for high network usage outside the CUDN (i.e. outside of the University). Students will be charged if the amount of traffic used is larger than 32 gigabytes over the term. Students will be notified if this limit is exceeded and sent a number of warnings by email before that point. Repeated excessive network use may also incur an administration charge. Students who have an academic requirement to use a large amount of data traffic should apply to the IT Manager with authorisation from their Tutor and Director of Studies for an increased traffic quota. Graduate students requiring to use a large amount of data traffic should discuss reimbursement with their department.
