Between September 19 and September 30, 2003 all systems requesting access to the campus network will be scanned for vulnerabilities and infections. Systems found to be vulnerable or infected will be denied access until security patches are updated. A new Web site, the Windows Vulnerability Check site at http://winfix.ucdavis.edu/, has been developed to assist the campus community in ensuring all computer systems are secure prior to connecting to the network. This Web site provides access to an automated self-test that takes only seconds to complete, information about Windows security, and downloadable Windows updates and patches. Additional information and resources related to the Windows RPC vulnerabilities and the campus' response are available on the Vulnerability Resources page at http://security.ucdavis.edu/vuln_resources.cfm.
