  Warnings (2):
  ----------------------------
  ! iptables module(s) loaded, but no rules active [FIRE-4512] 
      https://cisofy.com/lynis/controls/FIRE-4512/

  ! MongoDB instance allows any user to access databases [DBS-1820] 
      https://cisofy.com/lynis/controls/DBS-1820/

  Suggestions (25):
  ----------------------------
  * Set a password on GRUB boot loader to prevent altering boot configuration (e.g. boot in single user mode without password) [BOOT-5122] 
      https://cisofy.com/lynis/controls/BOOT-5122/

  * Consider hardening system services [BOOT-5264] 
    - Details  : Run '/usr/bin/systemd-analyze security SERVICE' for each service
      https://cisofy.com/lynis/controls/BOOT-5264/

  * Check PAM configuration, add rounds if applicable and expire passwords to encrypt with new values [AUTH-9229] 
      https://cisofy.com/lynis/controls/AUTH-9229/

  * Configure password hashing rounds in /etc/login.defs [AUTH-9230] 
      https://cisofy.com/lynis/controls/AUTH-9230/

  * When possible set expire dates for all password protected accounts [AUTH-9282] 
      https://cisofy.com/lynis/controls/AUTH-9282/

  * To decrease the impact of a full /home file system, place /home on a separate partition [FILE-6310] 
      https://cisofy.com/lynis/controls/FILE-6310/

  * To decrease the impact of a full /var file system, place /var on a separate partition [FILE-6310] 
      https://cisofy.com/lynis/controls/FILE-6310/

  * Consider disabling unused kernel modules [FILE-6430] 
    - Details  : /etc/modprobe.d/blacklist.conf
    - Solution : Add 'install MODULENAME /bin/true' (without quotes)
      https://cisofy.com/lynis/controls/FILE-6430/

  * Check DNS configuration for the dns domain name [NAME-4028] 
      https://cisofy.com/lynis/controls/NAME-4028/

  * Install debsums utility for the verification of packages with known good database. [PKGS-7370] 
      https://cisofy.com/lynis/controls/PKGS-7370/

  * Install package apt-show-versions for patch management purposes [PKGS-7394] 
      https://cisofy.com/lynis/controls/PKGS-7394/

  * Determine if protocol 'dccp' is really needed on this system [NETW-3200] 
      https://cisofy.com/lynis/controls/NETW-3200/

  * Determine if protocol 'sctp' is really needed on this system [NETW-3200] 
      https://cisofy.com/lynis/controls/NETW-3200/

  * Determine if protocol 'rds' is really needed on this system [NETW-3200] 
      https://cisofy.com/lynis/controls/NETW-3200/

  * Determine if protocol 'tipc' is really needed on this system [NETW-3200] 
      https://cisofy.com/lynis/controls/NETW-3200/

  * Enable logging to an external logging host for archiving purposes and additional protection [LOGG-2154] 
      https://cisofy.com/lynis/controls/LOGG-2154/

  * Check what deleted files are still in use and why. [LOGG-2190] 
      https://cisofy.com/lynis/controls/LOGG-2190/

  * Add a legal banner to /etc/issue, to warn unauthorized users [BANN-7126] 
      https://cisofy.com/lynis/controls/BANN-7126/

  * Add legal banner to /etc/issue.net, to warn unauthorized users [BANN-7130] 
      https://cisofy.com/lynis/controls/BANN-7130/

  * Enable sysstat to collect accounting (no results) [ACCT-9626] 
      https://cisofy.com/lynis/controls/ACCT-9626/

  * Enable auditd to collect audit information [ACCT-9628] 
      https://cisofy.com/lynis/controls/ACCT-9628/

  * Determine if automation tools are present for system management [TOOL-5002] 
      https://cisofy.com/lynis/controls/TOOL-5002/

  * Consider restricting file permissions [FILE-7524] 
    - Details  : See screen output or log file
    - Solution : Use chmod to change file permissions
      https://cisofy.com/lynis/controls/FILE-7524/

  * Double check the permissions of home directories as some might be not strict enough. [HOME-9304] 
      https://cisofy.com/lynis/controls/HOME-9304/

  * One or more sysctl values differ from the scan profile and could be tweaked [KRNL-6000] 
    - Solution : Change sysctl value or disable test (skip-test=KRNL-6000:<sysctl-key>)
      https://cisofy.com/lynis/controls/KRNL-6000/

  Follow-up:
  ----------------------------
  - Show details of a test (lynis show details TEST-ID)
  - Check the logfile for all details (less /var/log/lynis.log)
  - Read security controls texts (https://cisofy.com)
  - Use --upload to upload data to central system (Lynis Enterprise users)
