The source code is available either from the labshare or online. Next we need a few tools that are not part of the standard install. There is one more required package, but it lives on the second install DVD, so change discs and ~]# yum -disablerepo=\* -enablerepo=c6-media install libpcap-devel Mysql-devel postgresql postgresql-devel openssl-devel I also want to add a few packages to enable database support and SSL support for ~]# yum -disablerepo=\* -enablerepo=c6-media install mysql I have put an updated version of the CentOS 6.2 image on the labshare which will work. If you try to run this command on the original base image on the labshare, it will fail. It was not intentional, but there you have it. At some point when I was working with the virtual machines and before I put them on the lab share, I updated the version of gcc to 4.4.7 from 4.4.6. All of these (except for libpcap-devel) are on the first install DVD, so all we need to to is yum -disablerepo=\* -enablerepo=c6-media install gcc-c++ flexīison pcre-devel zlib-devel automake libtool The first group of packages we want to install are needed for Snort to compile, they include gcc-c++ flex bison pcre-devel zlib-devel libpcap-devel automake and libtool. Umm, more than just a few actually, and it looks like I made a teensy error earlier in the semester. To make the temporary but immediate change, simply echo 0 >/selinux/enforceīefore we can install snort, we will need a few packages that we did not install as part of the default image for class. These changes will take effect only on the next reboot. Remember, to so this we edit /etc/selinux/config and making the necessary changes. You probably don’t want to do this on a production system, but this will greatly simplify our installation process. The installation process is somewhat different, but the configuration is the same.Īfter seeing the difficulties we had with SELinux on our web server, we start by setting SELinux to permissive mode.

We also note that Snort can be installed on Windows systems. Though this machine is being designed primarily as a sensor, it is possible to install Snort on machines dedicated to other tasks. In these notes, we will install the current version of Snort on our CentOS 6.2 圆4 machines. In our laboratory class environment, note that VMWare internally uses essentially a hub for network traffic thus a virtual machine running Snort will see all of the traffic directed to/from either the host or any of the guests running on that physical host. Snort generates alerts only for traffic that it collects, so when deploying a snort sensor it is important to know what traffic it will see. A sequence of malicious traffic that does not match any existing signature will not generate an alert (false negative), while it can also be the case that perfectly legitimate traffic may match a signature and be flagged as malicious (false positive). It can generate alerts when it sees traffic patterns that match its list of signatures. Snort is an open source intrusion detection system available for most major platforms.
