Whats New

  • Alert Output support for JSON and ZeroMQ
  • Syscheck improvements
  • Report file deletion, even without realtime enabled
  • Report modifications made on directories
  • Corrects bug so that files created between the first and second scan are reported as new files
  • Corrects bug that made changes reverting a file to the state it was in when ossec started unreported
  • Avoids computing hashes multiple times to improve performance
  • Make the time between two syscheck wakeups configurable in internal_options
  • Add support for the “nodiff” option when using report_changes, sensitive files tagged with in ossec.conf will not have their contents included in an alert.
  • IPv6 support
  • Support to call an external mailer. This solves the problem of supporting encryption when sending mail alerts in OSSEC. The <smtp_server> field can now be prepended with “/” to designate a local binary. Example: “<smtp_server>/usr/sbin/sendmail -t</smtp_server>”.
  • Slack notification support
