Title of Service: Network Security Services (OxCERT)
Status of Document: This document describes services offered in July 2011.
1.1 The University runs an "open" network, with many means of access to and from the outside world. It has high-bandwidth connections to the Internet, making it a prime target for those wishing to compromise computers to use for further exploits. The devolved responsibility for maintaining and updating systems means that many are vulnerable.
The team has a documented policy on network monitoring and log retention, as well as further information on incident handling.
