aureport - a tool that produces summary reports of audit daemon logs

aureport [options]

aureport is a tool that produces summary reports of the audit system logs. The aureport utility can also take input from stdin as long as the input is the raw log data. The reports have a column label at the top to help with interpretation of the various fields. Except for the main summary report, all reports have the audit event number. You can subsequently lookup the full event with ausearch -a event number. You may need to specify start & stop times if you get multiple hits. The reports produced by aureport can be used as building blocks for more complicated analysis.

Report about authentication attempts
Report about avc messages
Report about commands run
Report about config changes
Report about crypto events
Report about events
This option determines if the output is escaped to make the content safer for certain uses. The options are raw , tty , shell , and shell_quote. Each mode includes the characters of the preceding mode and escapes more characters. That is to say shell includes all characters escaped by tty and adds more. tty is the default.
Report about files and af_unix sockets
Only select failed events for processing in the reports. The default is both success and failed events.
Report about hosts
Print brief command summary
Interpret numeric entities into text. For example, uid is converted to account name. The conversion is done using the current resources of the machine where the search is being run. If you have renamed the accounts, or don't have the same accounts on your machine, you could get misleading results.
Use the given file or directory instead of the logs. This is to aid analysis where the logs have been moved to another machine or only part of a log was saved.
Use the log file location from auditd.conf as input for analysis. This is needed if you are using aureport from a cron job.
Report about integrity events
Report about audit rule keys
Report about logins
Report about account modifications
Report about Mandatory Access Control (MAC) events
Report about anomaly events. These events include NIC going into promiscuous mode and programs segfaulting.
Only select events originating from node name string for processing in the reports. The default is to include all nodes. Multiple nodes are allowed.
Do not include the CONFIG_CHANGE event. This is particularly useful for the key report because audit rules have key labels in many cases. Using this option gets rid of these false positives.
Report about processes
Report about responses to anomaly events
Report about syscalls
Only select successful events for processing in the reports. The default is both success and failed events.
Run the summary report that gives a total of the elements of the main report. Not all reports have a summary.
This option will output a report of the start and end times for each log.
Report about tty keystrokes
Search for events with time stamps equal to or before the given end time. The format of end time depends on your locale. If the date is omitted, today is assumed. If the time is omitted, now is assumed. Use 24 hour clock time rather than AM or PM to specify time. An example date using the en_US.utf8 locale is 09/03/2009. An example of time is 18:00:00. The date format accepted is influenced by the LC_TIME environmental variable.

You may also use the word: now, recent, boot, today, yesterday, this-week, week-ago, this-month, this-year. Now means starting now. Recent is 10 minutes ago. Boot means the time of day to the second when the system last booted. Today means now. Yesterday is 1 second after midnight the previous day. This-week means starting 1 second after midnight on day 0 of the week determined by your locale (see localtime). Week-ago means 1 second after midnight exactly 7 days ago. This-month means 1 second after midnight on day 1 of the month. This-year means the 1 second after midnight on the first day of the first month.

Report about terminals
Search for events with time stamps equal to or after the given end time. The format of end time depends on your locale. If the date is omitted, today is assumed. If the time is omitted, midnight is assumed. Use 24 hour clock time rather than AM or PM to specify time. An example date using the en_US.utf8 locale is 09/03/2009. An example of time is 18:00:00. The date format accepted is influenced by the LC_TIME environmental variable.

You may also use the word: now, recent, boot, today, yesterday, this-week, week-ago, this-month, this-year. Boot means the time of day to the second when the system last booted. Today means starting at 1 second after midnight. Recent is 10 minutes ago. Yesterday is 1 second after midnight the previous day. This-week means starting 1 second after midnight on day 0 of the week determined by your locale (see localtime). Week-ago means starting 1 second after midnight exactly 7 days ago. This-month means 1 second after midnight on day 1 of the month. This-year means the 1 second after midnight on the first day of the first month.

The boot time option is a convenience function and has limitations. The time it calculates is based on time now minus /proc/uptime. If after boot the system clock has been adjusted, perhaps by ntp, then the calculation may be wrong. In that case you'll need to fully specify the time. You can check the time it would use by running:

date -d "`cut -f1 -d. /proc/uptime` seconds ago"
