process where host.os.type == "linux" and event.type == "start" and
event.action in ("exec", "exec_event", "start", "executed", "process_started", "ProcessRollup2") and
process.name == "sudo" and process.args like ("-R", "--chroot*") and
// To enforce the -R and --chroot arguments to be for sudo specifically, while wildcarding potential full sudo paths
process.command_line like ("*sudo -R*", "*sudo --chroot*")
