Upgrading our network security
We are carrying out work to upgrade our network security in order to ensure the University remains safe from cyber-attacks. On Tuesday, 29 June, we will change the configuration on our network Intrusion Prevention System (IPS) to block high-level threats from accessing the University network.
The IPS is an industry standard security application that monitors incoming network traffic for signs of malicious activity. The technology works by consulting a database of known cyber-attack patterns and flags any activity that matches those patterns.
When the IPS detects a match, it selects an automated response, ranging from logging the activity and alerting us to potential threats to automatically blocking the traffic from entering the network.
Our recently installed IPS is currently set up to monitor and alert us, however, the change will ensure that this goes one step further by blocking and preventing all high-level threats from accessing the University network.
Why are we doing this?
As you may have seen in the press there has been an increase in ransomware and other types of cyber-attacks on UK Universities and Colleges during the last few years.
We have already put a number of steps in place to ensure that our network is secure. The change to our IPS will add an additional level of protection that will make sure that the University is less vulnerable to these types of attacks.
The change should not prevent legitimate traffic accessing the University network. However, if you do discover that you are unable to receive a file or other information from outside the University because it has been blocked then please raise a call through the IT Service Desk.
You can find further information about our IPS in our Knowledge Base article KB15604.
