Do you have experience of participating in User Groups? Which ones would you recommend? Are they free of charge? Are there particular people you go to for security advice? What about security blogs - which do you find most useful?
I look at Securityfocus list regulary and i think they are the best www.securityfocus.com Coming to blogs my choice is the MS Technet Blog. http://blogs.technet.com/MainFeed.aspx?GroupID=6 and on websites SANS are good www.sans.org
As they say in golf: “Amateurs, teach amateurs to be amateurs” – Newsgroups are interesting for hacking information, but I only trust the advice from professional sources for my clients, such as: F-Secure, Secunia, and Microsoft blogs like yours & Jesper Johansson.
I generally use www.security-forums.com. I also use www.msexchange.org and www.isaserver.org, they all have free forums and usually help me to resolve any issues.
I've just discovered a fantastic security portal: www.infosyssec.com
Definitely my new first port of call when I need to know anything security related... particularly hot issues.
I'm fond of reminding people that the only difference between an amateur and a professional is that the professional is paid, and the amateur does it solely for pleasure. Both categories include people who know, and people who don't.
I’m not insinuating that amateurs can not also be knowledgeable people. But with the exception of the Olympics, professionals usually do outperform amateurs.
Steve was specifically asking about “security,” not asking your neighbor’s advice on how to cook a chicken!
I prefer taking my advice from a professional who has a full-time investment in the security field.
I prefer taking my advice from a professional who is supported by other security professionals from their company.
I prefer taking my advice from a professional who has a documented successful history in the security field.
I prefer taking my advice from a professional with security credentials.
I prefer taking my advice from a professional, because if something goes wrong I have some legal recourse!
