Disclosure date: 17 September 2013
Please provide me with information on the number of times attempts were made on the university computer network to access websites with the following IP addresses:
I require this information for the period September 2012 - June 2013. If you cannot provide information for this date range, please provide the information for the month of May 2013 only.
Please do not provide any information which may lead to internet users becoming identifiable. If the figures are not available, please contact me to discuss how traffic is recorded.
We are unable to provide information for these periods as we only store data dating back one month.
Network traffic is recorded via Syslog from network devices such as SOAS’s Firewalls and Web Proxy servers - this is received by two Syslog servers which filter and store it in date stamped folders in a mount point on the SAN. These log files are compressed on a daily basis, and deleted after a month. We currently hold about 13 GBs of Syslog data - though this figure fluctuates depending on the time of year.
