The Australian subsidiary of Microsoft, Microsoft Australia Pty. Ltd. is taking development and infrastructure security seminars to the street with a national tour in March.
If you are in Australia and would like to attend one of the day long free security sumit, you can register via this link. There are two tracks, one for developers (eg. Writing secure ASP.NET applications) and one for infrastructure professionals (firewalls, security config of Windows networks etc). Another Melbourne based MS man, Dave Glover, is busy putting the final touches on his ASP.NET session as we speak.
The tour kicks of in Brisbane and then takes in the other major capitals during the month of March. Well worth the time investment.
