Colleagues, I also just joined this list. CWA is a R&D consulting business, doing engineering projects for various clients. I'm the resident expert on things related to the Internet, because I'm the one who pushed to get us connected. Otherwise, I'm a mild-mannered senior software engineer with a "day job" full of things to do (mostly real-time systems, UNIX applications, and for a lot of money, DOS/Windows stuff). Because our clients need to be assured that their sources and strategic plans and, in some cases, prototype products are safe on our network, I put intrusion detection tools high on my list of things that need to be in place and working before I can hand over day-to-day security worries to our solitary, overworked sysadmin. +----------------------------------------------------------------------+ | Dan Murphy, Sr. Wizard, CWA, 401 Alberto Way #1, Los Gatos, CA 95032 | | EMail: dmurphy@cwa.com | VoiceMail: 408-358-1529 | Fax: 408-356-7061 | +----------------------------------------------------------------------+
