OSSEC v2.7 Beta-0 Released
OSSEC is an Open Source Host-based Intrusion Detection System that performs log analysis, file integrity checking, policy monitoring, rootkit detection, real-time alerting and active response.
It runs on most operating systems, including Linux, MacOS, Solaris, HP-UX, AIX and Windows.
Changelog v2.7 Beta-0
- Installation
- Add hybrid mode – allows the same host to be both a server and an agent, useful for multi-tier OSSEC deployment.
- Add ‘ manage_agents -f’ option for bulk generation of client keys from an input file.
- Syscheck
- Add prelinking support – reduce confusion when a file change is the result of prelinking.
- Rootcheck
- Add fine-grained configuration control – allows you to turn ON/OFF individual rootcheck tasks for more efficiency and flexibility (default is all ON).
- Log monitoring/analysis
- Add GeoIP lookup support – allows geographical city names to be associated with IP addresses in OSSEC alerts, for more intelligent correlation.
- Add multi-line log readers for Linux auditd, plus ModSec and Regex log readers.
- Alert options and syslog output
- Add syscheck MD5/SHA1 sum to alerts for easier integration with third-party file signature checking.
- Support JSON and Splunk formats in syslog output.
- Rules and other notable changes/fixes
- Windows 2000 logs support has been deprecated (but will probably still work fine). Vista and Windows Server 2008 logs are now officially supported.

- Update decoders include: PIX, auditd, apache, pam, php…
- Many updated rules, such as new checks for vulnerable web apps exploitation attempts.
- Update rootcheck rules
- ossec-client.sh now allows for ‘reload’, in addition to ‘restart’
