They have several spyware (and other) rules at www.bleedingsnort.com -----Original Message----- From: Turnquist,Wayne [mailto:WayneTurnquist () catholichealth net] Sent: Friday, July 09, 2004 2:14 PM To: snort-users () lists sourceforge net Subject: [Snort-users] (no subject) To give some details, we connect to the internet by connecting to the corp. data center along with a bunch of other hospitals. Since security is becoming more of a problem because of all the Viruses/Trojan horses, I decided we need to tighten our side up even tho corp. has firewalls and other security process. So I want to get snort up and running and to watch for the basic attacks. I don't what to have to constantly twitch the rules because I don't have much time since I'm a one man shop hear at the hospital. Would the standard rules and the options for the rules that come with the installation of snort be good enough or should I turn on some other rules that are disabled in the standard install. right now I have the router to corp---->hub---->switch, where I have snort and ntop installed in the hub on 2 different pc's I have a windows 2000 pro with all the updates I installed snort 2.1.3 and winpcap 3.0 on another win2000 pro I have kiwi syslog running I'm using the installed rules and conf except for the following changes to the installed conf var HOME_NET[10.110.96.0/24,10.110.97.0/24,10.110.99.0/24,10.110.100.0/23,10.110.102.0/24,10.110.106.0/24,10.1.1.0/24] var DNS_SERVERS [10.110.101.231/32,10.110.101.233/32] var SMTP_SERVERS [10.110.101.233/32] var SNMP_SERVERS [10.110.99.2/32,10.110.99.4/32] var RULE_PATH d:\ids\snort\rules output log_tcpdump: tcpdump.log output alert_syslog: host=10.110.99.4:514, LOG_AUTH LOG_ALERT I issue the following command at the d:\ids\snor\bin dir snort -c "d:\ids\snort\etc\snort.conf" -l d:\ids\snort\log -i 1 -d not host 10.250.24.25 it does create the alert.ids and the tcpdump file. but I'm not getting any syslog msg to the machine running kiwi syslog. I do have another device on the network sending msys to the syslog. so I know it can receive msg's 1)what is going wrong 2)assuming I get this to work, can I have syslog msg's sent to 2 different pc at the same time -------------------------------------------------------------- The next question. I want to get up and running quickly. In case of point the not host 10.250.24.25 is a solarwinds at the main corp. data center monitoring some equipment in our network. This seems to work but there is other equipment at corp. that I trust and for now I would like to trust fully and be more restrictive on these machine in the future. So my question is, how can I add, lets say 5 devices from corp. from not generating alerts? do I create file lets say it is called ty.txt not host x not host y not host z not host g not host k then use the following snort -c "d:\ids\snort\etc\snort.conf" -l d:\ids\snort\log -I 1 -d -f "c:\ty.txt" if this is not correct, can some one tell me how to do it correctly Another issue I noticed while playing around, is that my SNMP severs are generating alerts when they probe the router which is 10.110.101.254 even tho I used the var to declare my snmp pc's. Do I need to added this ip number to the not host file as state above. If not, what am I'm doing wrong thank you wt ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
