New securityonion-web-page package fixes an issue in the Apache configuration

Yesterday, we released a new version of the securityonion-web-page package:
http://blog.securityonion.net/2014/10/new-securityonion-web-page-and.html

That package updated the Apache configuration to disable SSLv3.  However, the package used "sed" to update /etc/apache2/mods-enabled/ssl.conf, which is a symlink to /etc/apache2/mods-available/ssl.conf.  When sed operates on a symlinked file, it replaces the symlink with a copy of the file and then makes its modifications.  The broken symlink would have caused issues with future package updates, so I've released a new version of the securityonion-web-page package that fixes the symlink and updates the original file properly.

The new package version is as follows:

securityonion-web-page - 20141015-0ubuntu0securityonion7

Issues Resolved

Issue 640: securityonion-web-page: previous update broke ssl symlink

New securityonion-web-page and securityonion-elsa-extras packages provide more SSL visibility

A vulnerability in SSLv3 was recently announced (nicknamed POODLE):
http://googleonlinesecurity.blogspot.com/2014/10/this-poodle-bites-exploiting-ssl-30.html
http://www.wired.com/2014/10/poodle-explained/
https://isc.sans.edu/diary/OpenSSL%3A+SSLv3+POODLE+Vulnerability+Official+Release/18827
https://www.imperialviolet.org/2014/10/14/poodle.html

In response to this, we recently added some SSLv3 queries:
http://blog.securityonion.net/2014/10/new-securityonion-web-page-package-adds.html

Today, we're adding some additional ELSA queries to allow you to see your SSL traffic grouped by version or by cipher.

SSL - Top SSL Versions

SSL - Top SSL Ciphers

Today's update will also reconfigure Security Onion's Apache instance to no longer accept connections using SSLv3.

The new package versions are as follows:

OSSEC 2.8.1

OSSEC 2.8.1 was recently released:
http://www.ossec.net/?p=1135

Notice in the comments there is an additional patch which has now been applied to OSSEC on github:
https://github.com/ossec/ossec-hids/pull/315

I've packaged OSSEC 2.8.1 (with the patch from github) and also fixed a performance issue in our OSSEC configuration.  Our OSSEC configuration now uses a new script called /usr/bin/sostat-interface to detect if an interface hasn't received any packets within a specific time interval (10 minutes by default).

The new package versions are as follows:

ossec-hids-server - 2.8.1-ubuntu10securityonion8
securityonion-sostat - 20120722-0ubuntu0securityonion31

The new packages have been tested by the following (thanks!):
David Zawdie

UPDATE 20141006 13:01
Scott F. found an issue in the postinst script:
https://groups.google.com/d/topic/security-onion/5LbonKad-88/discussion

This issue has been resolved and additional error handling has been added.  The new package version is:
ossec-hids-server - 2.8.1-ubuntu10securityonion10

Issues Resolved

Issue 589: OSSEC 2.8.1
https://code.google.com/p/security-onion/issues/detail?id=589

Issue 621: sostat: add sostat-interface
https://code.google.com/p/security-onion/issues/detail?id=621

Updating
The new packages are now available in our stable repo.  Please see the following page for full update instructions:
https://code.google.com/p/security-onion/wiki/Upgrade

After installing the new OSSEC package, you'll need to double-check /var/ossec/etc/ossec.conf and add back any local customizations.  You can then restart OSSEC as follows:

sudo service ossec-hids-server restart

Screenshots

Update Process

After updating, add back any local customization to ossec.conf and then run "sudo service ossec-hids-server restart"

OSSEC now runs /usr/bin/sostat-interface every 10 minutes to check for interfaces not receiving any traffic

When OSSEC sees that an interface hasn't received any packets, it alerts

OSSEC alert in Sguil

sostat now reports on the number of packets received during the last monitoring interval

New securityonion-bro-scripts and securityonion-web-page packages

As mentioned previously, Seth Hall has developed some comprehensive ShellShock detection scripts for Bro:

"This script detects successful exploitation of the Bash vulnerability with CVE-2014-6271 nicknamed "ShellShock". It's more comprehensive than most of the detections around in that it's watching for behavior from the attacked host that might indicate successful compromise or actual vulnerability."

https://github.com/broala/bro-shellshock
http://blog.securityonion.net/2014/09/bash-vulnerability-part-3.html
http://blog.securityonion.net/2014/09/new-securityonion-bro-scripts.html
http://blog.securityonion.net/2014/09/securityonion-bro-scripts-now-detects.html

Seth has updated these scripts again today to "Add shellscripts as a post-exploit detection mechanism.":
https://github.com/broala/bro-shellshock/commit/4be009f9b7bf8ce9b99533cb4c7b8dd76aba87b7

I've updated the securityonion-bro-scripts package to include these changes.  I've also updated the securityonion-web-page package to include some ELSA queries for "ShellShock Exploits" and "ShellShock Scanners".

New package versions:
securityonion-bro-scripts - 20121004-0ubuntu0securityonion38
securityonion-web-page - 20120722-0ubuntu0securityonion25
