Hi,

I would go with the fork option. You seem to have a process running which detects new server instances. This would be your main loop (pseudocode): 

my %found;
my %active;

# sighandler for sigchild
$SIG{'SIGCHLD'} = sub {
    my $pid = waitpid;
    delete $active{$pid};
};

while(running) {
    if(my $serverid = new_server_found()) {
        $found{$serverid} = {
            'name' => $servername,
            'otherinfo' => $otherinfo,
        };
        my $pid = fork;
        if(defined $pid) {
            # fork ok
            if($pid == 0) {
                 # this is in the child
                 do_all_stuff_necessary_for_hardening();
                 exit $rc;
            }
            else {
                # this is parent
                # You have the pid and you know that this
                # fork was concerning a server you found
                # probably you want to store this information
                $active{$pid} = $serverid;
            }
            
        else {
            # no fork => error handling
            die ("FATAL: Something went wrong");
        }

    }
    sleep(1);
}
