Check out SNORT which runs on UNIX. And reviewing firewall or router syslogs can help too. --Greg -----Original Message----- From: Thom Larner [mailto:[EMAIL PROTECTED] Sent: Monday, June 30, 2003 4:38 PM To: '[EMAIL PROTECTED]' Subject: Port scanning question Hi all, As a relative newcomer to the security field, but with a reasonable amount of experience in sys admin roles, I am now responsible for the network security of the (small) company I work for. One of the things I would like to do is determine if (when) our web server, which hosts our applications, is being port scanned. How do I go about this? Are there (free or cheap) tools that will help you do this? We run both Solaris and W2K Server boxes, and I would like to check both. Now I just have to determine what, if anything, to do if (when) we are being scanned... Thanks in advance for your help. Cheers, Thom. --------------------------------------------------------------------------- Evaluating SSL VPNs' Consider NEOTERIS, chosen as leader by top analysts!
