SecurityPortal: Ask Buffy - Nukenabber, IE 5 privacy, hits on port 111

Questions this week cover NukeNabber, http_referrer, restricting Win98, port 111, http redirection, and DShield.org:

  • I use a freeware product called NukeNabber. Link at: http://www.dynamsol.com/puppet/ It sounds an alarm and blocks the scanned or affected port automatically for a configurable period of time. Is this good enough? Do I need a product that has more firewall functionality?
  • I would like to know how I can block Internet Explorer 5 of releasing my last visited site to the next web site?
  • How can I deny to the user to install on client windows 98 under windows 2000 server?
  • Lately I am getting A LOT of hits on port 111 at home. Currently I am blocking it but according to my firewall logs I get around 30 - 50 hits a day from all over the world. I know that port 111 is the RPC port under NT (I'm running 2000 Pro.) and I was just wondering is it used for anything else. I've tried looking around on the web for any exploits involving port 111 but I did not find anything. But still, getting that many hits a day is suspicious to me.
  • I have a simple problem. I want that if any user types in http:\\url.com..by mistake then it should get redirected to https:\\url.com. I am using apachewebserver with jserv. Please tell me how to do about it.
