Executive summary ================= Any non UK site interested in seeing an MBone transmitted seminar on 21st November at 16:15 UTC entitled "FIREWALLS AS A NETWORK SECURITY TOOL" should contact me to get the IP address and TTL changed. Plug, caveat, etc ================= To enable "lone" security reseachers (i.e. not enough people in the dept to have regular Security Seminars) in the UK to "keep in touch", we transmit our departmental Security Seminars on the MBone each week, with a low TTL and administratively scoped to the UK (so we don't have to worry about clashing with other events. The AC.UK MBone is fully pruning, and typically has spare bandwidth). These are not big formal events, but typically have a dozen or two members of the department and other "locals" present. The termly program is available on the Web in http://www.cl.cam.ac.uk/Seminars under "Security seminars" [ That way you can see our more formal "Departmental Seminars" listing at the same time :-) ] It's run as a "DIY" service (i.e. members of the group set things up) so things may go amiss. However, if they do (or there are time zone problems) it is fairly simple to retransmit later (during UK office'ish hours -- unless someone has some magic to start up vat and vic or nv without using X) from the tape we make ... Full details ============ As Firewalls are of interest to both these lists (sorry for cross posting!) I thought I might take this oportunity to draw your attention to this particular seminar. See http://www.cl.cam.ac.uk:80/Seminars/mbone.html for the latest info (e.g. slides will appear when I get them), but here is the announcement (roughly) as I received it: *** *** *** *** *** University of Cambridge Computer Laboratory SECURITY SEMINAR SERIES SPEAKER: Alec Muffett, Sun Microsystems DATE: Tuesday 21st November at 4.15pm PLACE: Room TP4, Computer Laboratory TITLE: FIREWALLS AS A NETWORK SECURITY TOOL The "Firewall" - taking the (quite broad) definition of a firewall's being any device designed (in some manner) to restrict "soft" access to a network - has migrated from being a tool of the paranoid systems administrator, into being a standard part of modern network infrastructures. This seminar will review why this situation has come about, what modern firewall architectures (both basic and advanced) look like, examine what they can/cannot accomplish, and will speculate upon the future potential of firewalls as access-security devices. *** *** *** *** *** As noted above, by default these are normally restricted to UK MBone sites, so let me know in advance (the M/C IP address changes !) if it wanted further afield.
