Quick highlights:

• Choose your favorite flavor of 32-bit/64-bit Ubuntu (Ubuntu, Kubuntu, Lubuntu, Xubuntu, or Ubuntu Server)

• Add our PPA and our packages and run through the Setup wizard to get:

• Snort, Suricata, Bro, Sguil, Squert, Snorby, NetworkMiner

• PF_RING and AF_PACKET fanout for high performance and scalability

• ELSA - Enterprise Log Search and Archive

For full instructions, please see the Security Onion 12.04 Beta page on our Wiki.

Security Onion and Ubuntu 12.04.1

The current version of Security Onion is based on Ubuntu 10.04.  Ubuntu 12.04.1 was just released yesterday and is being offered to users of 10.04 as an upgrade.  Existing users of Security Onion should NOT accept this upgrade to 12.04!  This is untested, unsupported, and is likely to break your system.

We are currently working on the new version of Security Onion that is based on Ubuntu 12.04.1.  As a reminder, we won't be able to support in-place upgrades from Security Onion 10.04 to Security Onion 12.04.1 since most folks will be migrating from 32-bit to 64-bit.  Begin planning your migrations now.

For more details on the upcoming version of Security Onion, please see the following:

Dr. J's Poor Man DNS Anomaly Detection using Bro

Dr. Johannes Ullrich of the SANS Internet Storm Center posted a great DNS Anomaly Detection script based on the query logs coming from his DNS server. We can do the same thing with Bro's dns.log (where Bro captures all the DNS queries it sees on the network):

Issue 254: tcpflow 1.1.1 connection counter breaks Sguil's transcript window

Notes
This update installs the new tcpflow 1.2.6 at /usr/local/bin/tcpflow and a shim at /usr/bin/tcpflow.  The shim is just a bash script that runs the following:

/usr/local/bin/tcpflow -T%A.%a-%B.%b $@

The new version of tcpflow has a new output format so we execute the shim to call tcpflow with the correct -T options to produce the original tcpflow format that Sguil is expecting.

Issue 224: typo in nsm_sensor-ps-start
Issue 242: Set Suricata runmode to autofp
Issue 243: Remove VLAN setting from pcap_agent.conf


Notes
As you can see in the screenshot below, this update will create a bpf.conf file for each sensor interface on your system.  For example, if you have two sensor interfaces (eth0 and eth1), you'll now have two bpf.conf files:
/etc/nsm/$HOSTNAME-eth0/bpf.conf
/etc/nsm/$HOSTNAME-eth1/bpf.conf

The NSM scripts now pass the "-F /etc/nsm/$HOSTNAME-$INTERFACE/bpf.conf" to Snort and Suricata and "-f /etc/nsm/$HOSTNAME-$INTERFACE/bpf.conf" to daemonlogger.  However, Suricata's afpacket mode currently doesn't support bpf.  I've created Suricata feature request #440 for this.

Security Onion 20120312 now available!

Security Onion 20120312 is now available!  This resolves the following issues:

Issue 233: Snorby 2.5.0

Our original Snorby package was a good way of getting it deployed quickly.  However, the time has come to break the monolithic package up into separate packages:

1.  securityonion-ruby contains Ruby 1.9.2-p290 and replaces the existing system-wide Ruby 1.8 (/usr/bin/ruby).

2.  securityonion-snorby contains /usr/local/share/snorby (Snorby 2.5.0 and all required gems using "bundle install --deployment").

3.  securityonion-passenger allows us to run Snorby under Apache instead of using Ruby's "thin" web server.

These separate packages will make our Snorby implementation faster, more standardized, more secure, and more maintainable.  In addition, this update brings the newly-released Snorby 2.5.0, which has many features and bugfixes!

Issue 235: Need statistics/diagnostics script

/usr/bin/sostat is a simple bash script which collects details about your system and its processes.  When asking for help on the mailing list, we may ask you to run "sudo sostat" and copy the output to your email so that we can have some data to help us diagnose your issue.  We also recommend running sostat in a daily cronjob and having it send you an email for review.

Security Onion and Ubuntu's MySQL 5.1 update

Ubuntu just released new MySQL packages.  A few things to be aware of for Security Onion users:

• The update will stop MySQL in order to perform the update.  If sguild is running at the time, it will terminate as soon as MySQL stops.  Once you've successfully completed the update and MySQL is back up and running, you should run the following on your Security Onion server to start sguild:

sudo nsm_server_ps-start

• When updating a Security Onion SENSOR (that sends its alerts to a separate Security Onion server), the update will try to start MySQL, but it will hang since port 3306 is already in use (being forwarded to the server over SSH).  You can simply kill the startup since MySQL is currently not used on Security Onion sensors.  On subsequent reboots, MySQL will startup, but when /etc/init/securityonion.conf executes, it will stop MySQL and bring up the SSH tunnel with port 3306 forwarded to the server.

If you have any questions or problems, please send a detailed email to our mailing list.  Thanks!

Security Onion 20120224 now available!

Problem #1

Suppose you're monitoring traffic that has VLAN tags (in both directions).  By default, when you right-click the Alert ID in Sguil and request the transcript/pcap, you would get nothing.  In order to get transcripts/pcaps to work correctly in Sguil, you would have to manually set VLAN to "1" in pcap_agent.conf.

Problem #2
Suppose you're monitoring traffic that has VLAN tags in one direction but not the other.  When you right-click the Alert ID in Sguil and request the transcript/pcap, you would only get the non-VLAN side of the flow.  If you set VLAN to "1" in pcap_agent.conf, you would then receive just the VLAN side of the flow.

Solution

Security Onion 20120224 is now available!  This resolves the following issues:
Issue 148: Update tcpflow
Issue 222: Modify pcap_agent.tcl to support ip & vlan tagged interfaces

The updated pcap_agent.tcl and tcpflow allow Sguil to transparently support all cases of traffic with VLAN tags, without VLAN tags, and with mixed VLAN tags.  When you right-click the Alert ID and request the transcript/pcap, you should now get the entire flow.

Caveat
httpry doesn't support VLAN tags, so you still won't see HTTP events in Sguil where VLAN tags are involved.  However, we'll soon be removing httpry in favor of Bro's HTTP logging, which does handle VLAN tags properly.  In the meantime, you can query the Bro logs directly from the command-line using something like the following:

zgrep "192.168.123.234" /nsm/bro/logs/*/http*

Note
If you had manually set VLAN to "1" in pcap_agent.conf, then you should set it back to the default of 0 and restart pcap_agent:

sudo nsm_sensor_ps-restart --only-pcap-agent

Byobu and Security Onion

I really like having byobu configured for all my Security Onion SSH sessions, as it gives lots of good health/status information about the server in question:

Before

If you're not already running Byobu, run it by executing "byobu".  Then press the F9 key and set Byobu to launch automatically the next time you logon.

Now let's make byobu even more useful by having it display the Security Onion version number in the status bar at the bottom of the screen.  Copy/paste the following into your terminal:

mkdir -p $HOME/.byobu/bin
cat > $HOME/.byobu/bin/60_so <<EOF
#!/bin/sh
echo -n "Security Onion "
grep VERSION /etc/nsm/securityonion.conf | cut -d\= -f2
EOF
chmod +x $HOME/.byobu/bin/60_so 

Within a few seconds, your terminal should look like this:

After

This could be extended to display interface/packet statistics or any other data you wish.  For more information about Byobu, please see:
