Network security upgrade, phase two

We are making the University network more secure

At the end of June, we successfully carried out work to upgrade our network security systems by changing the configuration on our network Intrusion Prevention System (IPS) to block high-level threats from accessing our web servers.

An IPS is an industry standard security application that monitors incoming network traffic for signs of malicious activity by consulting a database of known cyber-attack patterns and flags any activity that matches those patterns.

Following the success of this Change we now plan to implement the second phase of the upgrade. On Friday, 23 July between 10.00am and midday we will carry out work to further increase the security on the University network by configuring the IPS to monitor all internet traffic coming into the University. This further upgrade will detect and prevent any critical or high-level threats from accessing or attacking the University network.

As you may be aware, 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. This further change to our IPS increases the level of protection on our network ensuring that the University is not 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 to your College IT Manager through the IT Service Portal.
