pySigma OSSEM Pipeline

This is the OSSEM pipeline for pySigma. It contains the ossem_to_sigma processing pipeline in sigma.pipelines.ossem, that transforms Sigma rules written with the field naming and value formats defined in the OSSEM project into the default Sigma taxonomy. Example:

title: Rule written with the OSSEM taxonomy.
status: stable
taxonomy: ossem
logsource:
    category: process_creation
    product: windows
detection:
    sel:
        process_command_line: whoami
        process_file_name: whoami.exe
        process_parent_file_name: httpd.exe
    condition: sel

By preprocessing this rule with the ossem_to_sigma pipeline it can be used like any other Sigma rule written in the default Sigma taxonomy.
