checksecurity binary package in Ubuntu Bionic s390x

 Checksecurity can periodically do some very basic system security checks:
 .
    * check-setuid - scans for insecurely mounted remote file systems,
      and tracks changes in setuid programs;
    * check-sockets - tracks changes in open ports to detect rogue programs;
    * check-passwd - scans for empty or duplicate system accounts;
    * check-disfree - scans for mounted filesystems nearing capacity;
    * check-iptables-logs - scans logs generated by iptables and look
      for intrusion attempts.
 .
 Be aware that these minimal set of checks are no substitute for a full
 security auditing and integrity checking system.
 .
 In addition to these checks you are encourage to install additional packages
 (listed in "Recommends") to provide more information concerning the security
 or vulnerability of your system.
 .
 Installing the suggested package lockfile-progs can help to prevent
 the cron jobs running multiple times if something gets jammed.
