Installing Snort and Barnyard2 Date: 2015-10-05 14:19:27 Snort is a widely used packet sniffer and IDS. The Installation of the Snort IDS from sources is quite straight forward with only minor obstacles however the configuration might need a little more effort. Of course it is possible to use the Snort packages from distributions such as Debian or Ubuntu, however that's often not the latest version, and we want to get our pork as fresh as possible. Installation of Snort To compile Snort from source, which is the best method to get the latest copy, we will be using either a Debian system, which of course needs all the tools to configure, compile and install stuff, or Arch-Linux where the following are included in the base-devel package and usually installed already with the system. [root@debian ~]# snort -i eth0 When we start Snort like above, it basically runs like tcpdump -i eth0 -; just sniffing packets and displaying them without any rule processing. For processing rules we need a proper configuration file which we setup later.

Diesel Watch Dz7023 Manual High School on this page. Installing Barnyard2 Barnyard2 is a dedicated spooler for Snort. It relieves Snort from the task of writing and processing their alerts so it can focus on its main task: Sniffing the network for suspicious activities without bothering a connection to a database or similar. Barnyard2 monitors Snort's log directory and catches alerts from the spool file as they appear and send them somewhere else, in our case a MySQL database.

Barnyard2 can be obtained from its git repository, so we install git quickly if we haven't done it before. Since we use MySQL as our alert database, we need to install the required packages in the same run. Note: The setup of your MySQL server might vary on different distributions and will not be covered here. This tutorial only explains the creation of a user for barnyard2 and the required tables. Please refer to your MySQL documentation if you need help installing the server.

Therefore we have to get Snort using u2 as its log output. We use the example configuration of Snort, which we can or simply copy from the source directory. [root@debian ~]# vim /etc/snort/snort.conf In line:45 set HOME_NET to our local network ipvar HOME_NET 192.168.1.1/24 In line:104 set the following variables accordingly var RULE_PATH rules var SO_RULE_PATH so_rules var PREPROC_RULE_PATH preproc_rules var WHITE_LIST_PATH rules var BLACK_LIST_PATH rules In line:541 uncomment local.rules include $RULE_PATH/local.rules In line:516 define unified2 as the log format output unified2: filename snort.u2, limit 128, nostamp, mpls_event_types, vlan_event_types Now we have configured Snort to report in a format that can be read by Barnyard2.
