Thank you for your recent FOI

So far we have been very fortunate that the layers of security we have in place has stopped the majority of these attacks but we are staying vigilant as the attacks are increasing. We have never been the victim of a direct attack so have never lost any records etc

The attacks that caused us a problem were DoS which was found to be part of larger attack on UK Local Government which emanated from China. These cause the network to slow down or access to our website to slow down.
