NAMEaureport − a tool that produces summary reports of audit daemon logs
SYNOPSISaureport [options]
DESCRIPTIONaureport 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.
OPTIONS−au, −−auth Report about authentication attempts −a, −−avc Report about avc messages −−comm Report about commands run −c, −−config Report about config changes −cr, −−crypto Report about crypto events −−debug Write malformed events that are skipped to stderr. −−eoe−timeout seconds Set the end of event parsing timeout. See end_of_event_timeout in auditd.conf(5) for details. Note that setting this value will override any configured value found in /etc/auditd/auditd.conf. −e, −−event Report about events −−escape option 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. −f, −−file Report about files and af_unix sockets −−failed Only select failed events for processing in the reports. The default is both success and failed events. −h, −−host Report about hosts −−help Print brief command summary −i, −−interpret 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. −if, −−input file | directory 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. The path length is limited to 4064 bytes. −−input−logs Use the log file location from auditd.conf as input for analysis. This is needed if you are using aureport from a cron job. −−integrity Report about integrity events −k, −−key Report about audit rule keys −l, −−login Report about logins −m, −−mods Report about account modifications −ma, −−mac Report about Mandatory Access Control (MAC) events −n, −−anomaly Report about anomaly events. These events include NIC going into promiscuous mode and programs segfaulting. −−node node-name Only select events originating from node name string for processing in the reports. The default is to include all nodes. Multiple nodes are allowed. −nc, −−no-config 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. −p, −−pid Report about processes −r, −−response Report about responses to anomaly events −s, −−syscall Report about syscalls −−success Only select successful events for processing in the reports. The default is both success and failed events. −−summary Run the summary report that gives a total of the elements of the main report. Not all reports have a summary. −t, −−log This option will output a report of the start and end times for each log. −−tty Report about tty keystrokes −te, −−end [end-date] [end-time] 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, this-hour, 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. −tm, −−terminal Report about terminals −ts, −−start [start-date] [start-time] 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, this-hour, 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. −u, −−user Report about users −v, −−version Print the version and exit −−virt Report about Virtualization events −x, −−executable Report about executables
NOTEThe 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"
