Linux Advisory Watch is a comprehensive newsletter that outlines the
security vulnerabilities that have been announced throughout the week.
It includes pointers to updated packages and descriptions of each
vulnerability.
This week, advisories were released for apache, the Linux kernel, mysql,
xonix, ssmtp, openoffice, squid, cvs, Heimdal, iproute, pwlib, scorched,
tcpdump, cadaver, and mailman. The distributors include Conectiva, Debian,
Fedora, FreeBSD, Gentoo, Mandrake, Red Hat, and SuSE.

Professional Associations
Those of you who have been in the IT industry for years are probably
already familiar with most professional organizations. Some of the more
popular include ISSA (Information Systems Security Association),
USENIX/SAGE, ACM, IAPSC, and countless others. Most organizations require
its members to pay dues, but that is not without value. Because there are
so many different organizations, it is a better idea to pick one or two
and get heavily involved. Many organizations are worldwide, but have
local chapters. This provides many opportunities for benefit.
Did you ever wish you knew the right people? Local chapter meetings are
great for professional networking. Some organizations have quarterly
meetings, others hold them monthly. Chapter events are a great
opportunity to meet people that have similar interests and needs. If you
are in search for a specific security solution, often you will find
someone at a meeting who can offer it. Conversely, if you're a business
owner and wish to extend your services, meetings can be helpful.
Organizations such as the ISSA offer educational benefits. Usually
meetings include a lecture that is centered around an information security
topic. Other meetings can include practical demonstrations and
round-table discussions. Also, ad hoc study groups are often formed to
prepare for certification exams.
Do you need additional credentials on your resume/cv? Do you wish you
could prove to management that you are ready for a leadership position?
Professional organizations also offer its members the chance to lead.
Positions such as chapter president, vice president, secretary, etc. open
for election each year. Although time consuming, it can be a worthwhile
commitment.
Finally, most professional organizations have monthly/quarterly journals
that are written by members. Rather than being subject to corporate
pressures, you'll find the articles in these journals are of high quality
and relatively unbiased. Usually you can also find archives of past
papers/publications on each organization's Web site.
For more information about some of the professional organizations that
I've mentioned, please see the following Web sites:

Association for Computing Machinery

USENIX/SAGE

Until next time, cheers!
