NAME

6        Lynis - Run an system and security audit on the system
7

SYNOPSIS

9       lynis --check-all(-c) [other options]
10

DESCRIPTION

12       Lynis  is an auditing tool for Unix (specialists). It checks the system
13       and software configuration and logs all the found  information  into  a
14       log  file for debugging purposes, and in a report file suitable to cre‐
15       ate fancy looking auditing reports.  Lynis can be run as a cronjob,  or
16       from  the  command line. It needs to have full access to the system, so
17       running it as root (or with sudo rights) is required.
18
19       The following system areas may be checked:
20
21              - Boot loader files
22
23              - Configuration files
24
25              - Common files by software packages
26
27              - Directories and files related to logging and auditing

OPTIONS

30       --auditor <full name>
31              Define the name of the auditor/pen-tester. When a full  name  is
32              used, add double quotes, like "Michael Boelen".
33
34
35       --checkall (or -c)
36              Lynis  performs  a  full  check  of the system, printing out the
37              results of each test to stdout. Additional information  will  be
38              saved into a log file (default is /var/log/lynis.log).
39
40              In  case  the  outcome  of a scan needs to be automated, use the
41              report file.
42
43       --check-update (or --info)
44              Show program, database and update information
45
46       --cronjob
47              Perform automatic scan with cron safe  options  (no  colors,  no
48              questions, no breaks).
49
50       --no-colors
51              Do not use colors for messages, warnings and sections.
52
53       --no-log
54              Redirect all logging information to /dev/null, prevent sensitive
55              information to be written to disk.
56
57       --quick (-Q)
58              Do a quick scan (don't wait for user input)
59
60       --quiet (-q)
61              Try to run as silent as possible, showing  only  warnings.  This
62              option activates --quick as well.
63
64       --reverse-colors
65              Optimize screen output for light backgrounds.
66
67       --tests TEST-IDs
68              Only  run  the  specific test(s). When using multiple tests, add
69              quotes around the line.
70
71       Multiple parameters are allowed, though some  parameters  can  only  be
72       used  together  with others. When running Lynis without any parameters,
73       help will be shown and the program will exit.
