Port Scan

Page

IT is running port scans regularly on all network attached machines campus wide to identify any potential security concerns.  If your Mac computer is scanned, your Symantec Endpoint Protection software may show a "Vulnerability BLOCKED" message.  If you click "Options->More Info" and the IP address is from either 129.186.6.24, 129.186.6.25, or 129.186.6.4, you can simply ignore this message. See below for an example.
