- Fix a bug where some rules marked silent would trigger an alert.
- Load Sonicwall and Spamassassin ruleset by default.
- Fix rule syntax problem in Sonicwall ruleset.
- Fix rule indexing problem in Squid ruleset.
- Postfix rule consistency fix.
2) Changed permissions on plugins.rules and prelude-lml.conf so that
prelude-lml can run unpriviledged
3) Changed confdir in configure so that plugins.rules and prelude-lml.conf
are found.
Changes in 0.9.5:
- Experimental context support (ala SEC): we now handle
multiline log matching.
- Update PAX rules so that it use the new context feature.
- Don't exit on statistics signal, improve statistics precision,
make them easier to read.
- Fix some problem with user & group options.
- text-output argument is optional.
- New experimental ruleset: Sonicwall and Spamassassin. These
need to be manually hooked to pcre.rules if you plan to use
them.
- Fix FAM activation switches.
Changes:
- Remove trailing space from regex we get from plugins.rules (this fix
a match problem on log entry that didn't contain any space).
- Add --user / --group option to drop privilege. However, make sure it is
not allowed to open file that the target user can not read, because it
would lead to failure when trying to re-open the logfile after a rotation.
- Signal handling improvement.
- Fix priority for --quiet option.
- Use newer libprelude IDMEF_LIST_APPEND/IDMEF_LIST_PREPEND addition.
- Add unhandled arguments warning.
- Get rid of the 1024 characters per line limitation (defined as per
the syslog RFC), since LML is not limited to parsing input from syslog
anymore.
- Handle events in Clamav logging format as well as syslog.
- Abstracted Squid chain regex to allow parsing of data directly
from Squid log files.
- Introduced support for openhostapd.
- Began expanding rulesets with additional_data and vendor-specific
classification data.
- Various ruleset updates and bug fixes.
Prelude-LML is a signature based log analyzer monitoring logfile and
received syslog messages for suspicious activity. It handle events
generated by a large set of components, including but not limited to:
BigIP, Grsecurity, Honeyd, ipchains, Netfilter, ipfw, Nokia ipso,
Nagios, Norton Antivirus Corporate Edition, NTsyslog, PAM, Portsentry,
Postfix, Proftpd, ssh, etc.
sensors, managers, and a display console.
Prelude-lml is the log file analyzer. It scans
system log files and generates IDMEF alerts to
the prelude-manager based on signature rulesets.
This is one of sever new Prelude packages.
