http://www.squertproject.org/
https://github.com/int13h/squert

He also recorded a walkthrough video of some of the new features recently added to Squert:

I've packaged Squert 1.1.5 and the package has been tested by the following (thanks!):
Pedro Simoes
JP Bourget
David Zawdie

Release Notes

  • Please note that /var/www/squert/.inc/config.php gets overwritten during the update process so if you had previously set sgUser and sgPass to enable transcripts and event classification, you'll need to re-apply those settings.
  • Please also note that you may need to Shift-Reload in your browser and/or empty browser cache to ensure you're running the latest Squert javascript.
  • Timestamps are displayed in UTC by default, but you can change this by clicking the arrows to the right of the timeline.  De-select UTC, then specify your local timezone offset.  Then click "Save" to save your preference into the database and click "Update" to refresh the page with the new timestamps.  See the "Time Selection" screenshot below.

New securityonion-sostat package includes sostat-redacted

The securityonion-sostat package now includes a new script called sostat-redacted which runs sostat and pipes the output to sed, redacting any IPv4 addresses.  When you need help from our mailing list and we request that you send redacted sostat output, you can now use sostat-redacted to automatically redact the IPv4 addresses (although there may be additional sensitive info that you still need to redact).  Thanks to Steve Fennell for the suggestion!

New NSM/Setup Packages now available

New versions of the following packages are now available!
securityonion-nsmnow-admin-scripts
securityonion-setup

Issues Resolved

Issue 376: netsniff-ng: specify ring buffer size
When running Setup and choosing Advanced Setup, you can now specify netsniff-ng's ring buffer size.
https://code.google.com/p/security-onion/issues/detail?id=376

Issue 400: Add option to Advanced Setup to enable netsniff-ng mmap I/O
When running Setup and choosing Advanced Setup, you can now enable mmap I/O for netsniff-ng.
https://code.google.com/p/security-onion/issues/detail?id=400

Issue 394: syslog-ng memory leak
/etc/cron.d/sensor-newday was doing "syslog-ng reload" which was causing a memory leak.  It now does a full "syslog-ng restart" to avoid the memory leak.
https://code.google.com/p/security-onion/issues/detail?id=394

Issue 391: Setup should write log file to /tmp and then copy to /var/log/nsm/sosetup.log when done
While Setup is running, you can monitor /tmp/sosetup.log.  After Setup has completed, you can find the log at /var/log/nsm/sosetup.log.
https://code.google.com/p/security-onion/issues/detail?id=391

Issue 377: Move Argus config to argus.conf so that users can change without modifying NSM scripts
Each sensor will now have its own argus.conf at /etc/nsm/HOSTNAME-INTERFACE/argus.conf that you can use to customize your Argus configuration.
https://code.google.com/p/security-onion/issues/detail?id=377

Issue 401: ossec_agent.conf should set DAEMON to 0
The default ossec_agent.conf had DAEMON set to 1, but our NSM scripts expect spawned processes to NOT daemonize.  The NSM scripts now set DAEMON to 0 in ossec_agent.conf to avoid this.
https://code.google.com/p/security-onion/issues/detail?id=401

New Video on OSSEC and ELSA

I just published a quick video on OSSEC and ELSA. In this video, you'll see how quickly you can configure OSSEC and ELSA using Security Onion.  We'll then use the ELSA web interface to hunt through OSSEC alerts and all logs received from all OSSEC agents.  Also note that you can send standard syslog to ELSA and query those logs as well.
