NAME

        Lynis - Run an system and security audit on the system

SYNOPSIS

       lynis --check-all(-c) [other options]

DESCRIPTION

       Lynis  is  a  security  auditing  tool  for  Linux  and  Unix  systems. It checks the system and software
       configurations, to determine any improvements.  All details are logged in a log file. Findings and  other
       data  is  stored  in  a report file, which can be used to create auditing reports.  Lynis can be run as a
       cronjob, or from the command line. Lynis prefers root permissions (or sudo), so it can access  all  parts
       of the system, however it not required (see pentest mode).

       The following system areas may be checked:

              - Boot loader files

              - Configuration files

              - Files part of software packages

              - Directories and files related to logging and auditing

OPTIONS

       --auditor <full name>
              Define the name of the auditor/pen-tester. When a full name is used, add double quotes, like "Your
              Name".

       --checkall (or -c)
              Lynis performs a full check of the system, printing out  the  results  of  each  test  to  stdout.
              Additional information will be saved into a log file (default is /var/log/lynis.log).

              In case the outcome of a scan needs to be automated, use the report file.

       --cronjob
              Perform automatic scan with cron safe options (no colors, no questions, no breaks).

       --debug
              Display debug information to screen for troubleshooting purposes.

       --dump-options
              Show all available parameters.

       --logfile </path/to/logfile>
              Defines location and name of log file, instead of default /var/log/lynis.log.

       --no-colors
              Do not use colors for messages, warnings and sections.

       --no-log
              Redirect  all  logging  information  to  /dev/null, prevent sensitive information to be written to
              disk.

       --pentest
              Run a non-privileged scan, usually for penetration testing. Some of the tests will be  skipped  if
              they require root permissions.

       --plugin-dir </path/to/plugins>
              Define location where plugins can be found.

       --profile </path/to/profile>
              Provide alternative profile to perform the scan.

       --quick (-Q)
              Do a quick scan (don't wait for user input).

       --quiet (-q)
              Try to run as silent as possible, showing only warnings. This option activates --quick as well.

       --report-file </path/to/report>
              Provide an alternative name for report file.

       --reverse-colors
              Optimize screen output for light backgrounds.

       --tests TEST-IDs
              Only run the specific test(s). When using multiple tests, add quotes around the line.

       --tests-category <category>
              Only perform tests from particular tests. Use --view-categories to determine valid options.

       --upload
              Upload data to Lynis Enterprise server.

       --view-categories
              Display all available test categories.

              Multiple  parameters  are  allowed,  though some parameters can only be used together with others.
              When running Lynis without any parameters, help will be shown and the program will exit.

HELPERS

       Lynis has special helpers to do certain tasks. This way the framework of Lynis is used, while at the same
       time  storing  most of the functionality in a separated file. This speeds up execution and keeps the code
       clean.

       audit  Run audit on the system or on other targets

       update Run updater utility

       To use a helper, run Lynis followed by the helper name
