OSSEC 2.7 key features:
- 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.
- During Agent installation, allow the OSSEC server to be specified using hostname instead of IP.
- 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. The 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.
- 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.
- Windows registry syscheck alert level has been reduced from 7 to 5 to reduce unnecessary noise from alerts which do not indicate a compromise.
- 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’
- Many bug fixes…
- LICENSE text updated by adding exception clause for OpenSSL, while OSSEC is still under GPLv2
Enjoy!
