Requirements

This role will work on:

  • Red Hat
  • Ubuntu
  • Debian

So, you'll need one of those operating systems.. :-)

Role Variables

This role needs 4 parameters:

  • ossec_server_ip: This is the ip address of the server running the ossec-server.
  • ossec_server_fqdn: This is the fqdn of the server running the ossec-server.
  • ossec_server_name: This is the hostname of the server running the ossec-server used for delegate with ansible.
  • ossec_managed_server: When set to false, tasks that delegate to ossec server will be skipped

This role has 3 tasks with 'delagation_to' which needs the parameter ossec_server_name. When this parameter is not set, you'll need to run manually the /var/ossec/bin/ossec-authd on the server and /var/ossec/bin/agent-auth on the agent. When this is the case, it will show you an message with the exact command line.

The following role variables are optional:

  • ossec_active_response_disabled: Disables active response if set to yes. If this is not defined active response is enabled.
  • ossec_disable_public_repos: Disables installation of public repositories if set to "yes".
  • ossec_agent_package_name: Default is "ossec-hids-agent". This can be set to a URL or path to a .rpm file or path to a .deb file if the public repositories cannot be used.
  • ossec_agent_name: Optional name for the OSSEC agent. Default is to use hostname.

Dependencies

No dependencies.
