Description

Privilege Manager event log administration utility. Use pmlogadm to manage encryption options on the event log.

Options

pmlogadm has the following options.

Table 22: Options: pmlogadm
Option Description
-h, --help

Displays usage information.

help [<command>]

By default the help command displays the general usage output. When you specify a command, it displays a usage summary for that command.

-v, --version Displays the version number of Safeguard and exits.
Table 23: Global options: pmlogadm
Option Description
--verbose Enables verbose output.

--silent

Disables all output to stdout. Errors are output to stderr.

Table 24: Valid commands: pmlogadm
Option Description
archive

Moves old events to an archive.

archive <event_log_path> <archive_name> --before <YYYY-MM-DD> [--cleansource] [--dest-dir <destination_path>] [--no-zip]

-OR-

archive <event_log_path> <archive_name> --older-than <days> [--cleansource] [--dest-dir <destination_path>] [--no-zip]

Moves events that occurred before the indicated date (YYYY-MM-DD) to an archive-named archive_name. If you use the second form, specify the date as days before the current date.

The archive is created in the current working directory unless you specify a destination path using the --dest-dir option. By default, the archive is compressed using tar and gzip, but you can skip this using the --no-zip option, in which case the resulting archive is a directory containing the new log with the archived events.

All files in that directory are required to access the archive. To access the archive, use pmlog. Moving events to an archive may not reduce the actual file size of the event log. To reduce the file size, the source log must be cleaned. To clean the source log, add the --clean-source option.

When a large number of events are present in the source log this option can increase the archive process time and use a large amount of disk space while the process runs. Once started, do not interrupt the process.

backup Creates a backup of the source log (event_log_path), in location backup_log.
create

Creates new empty audit files for that log.

create <new_event_log_path>

This may include a keyfile which has the -kf suffix, a journal file with the -wal suffix, and a -shm system file. It is critical that the group of files that make up an event log remain together at all times. Removal of any one of these files may result in permanent loss of access to the event log.

encrypt

Enables or disables encryption of an event log.

encrypt enable|disable|rekey <event_log_path>

By default all event logs created by Safeguard are encrypted using the AES-256 standard. The encryption key is stored in the keyfile which is in the same path as the event log and has the same file name, and the -kf suffix. It is critical that this file remain in the same path as the main event log file.

You can decrypt the whole log file using the encrypt disable command, passing the path of the main event log file as an argument. Enable encryption using encrypt enable. The encrypt rekey command generates a new encryption key and re-encrypt all data in the event log using that new key data. The key file is automatically updated with the new key data if the operation succeeds.

import

Imports events.

import [-y|-n] <source_event_log> <dest_event_log>

Import events from source_event_log, adding them to dest_event_log.

info

Displays information about the event log.

info <event_log_path>

Displays information about the event_log_path. The information reported includes the current encryption status of the event log, the size of the file and the number of events contained in the log.

Settings

The following entries in the /etc/opt/quest/qpm4u/pm.settings file are used by pmlogadm

Table 25: Settings: pmlogadm
Option Description

eventLogQueue <pathname>

Specify the location of the event log queue, used by both pmmasterd and pmlogsrvd. This option is only used to determine whether the pmlogsrvd service is currently running.

For more usage information for a specific command, run:

pmlogadm help <command>

Files

The default Privilege Manager event log file is located at:

/var/opt/quest/qpm4u/pmevents.db

Other files that may be used by pmlogadm are:

  • settings file: /etc/opt/quest/qpm4u/pm.settings

pmlogsearch

Syntax
pmlogsearch [--csv] [--no-sort] 
               [--before "<YYYY/MM/DD hh:mm:ss>"] [--after "<YYYY/MM/DD hh:mm:ss>"] 
               [--user <username>] [--host <hostname>] [--result accept|reject] 
               [--text <keyword>]
               -h | --help  
               -v | --version
Description

Use the pmlogsearch command to perform a search on all logs in this policy group based on specified criteria.

You must specify at least one search condition; you can combine conditions.

Options

pmlogsearch has the following options.

Table 26: Options: pmlogsearch
Option Description
--csv

Outputs the search results in CSV format, suitable for consumption by Safeguard. If this option is not present, the output is human-readable.

One or more of the search criteria must be present, and any combination of the criteria is accepted. When multiple criteria are present they must all be matched (that is, the query criteria are combined using AND logic) for a log to be included in the results.

--after

--before

 Returns logs generated for sessions initiated after or before the specified time and date. For example:

# pmlogsearch --after “2012/01/04 00:00:00”

returns all logs for sessions since January 4, 2012.

# pmlogsearch --after “2012/01/01 00:00:00” --before “2012/12/31 23:59”

returns all logs generated during 2012.

--user <username> Searches for logs generated by sessions requested by the specified user name. username is case sensitive. For example:

# pmlogsearch --user harry

returns the locations of all keystrokelogs for sessions requested by the user named "harry".

The pattern may include the following wild card symbols:

  • * = match any string
  • ? = match any single character
--host <hostname>

Searches for logs generated by sessions that ran on hosts matching the given pattern. The pattern may include the following wild card symbols:

  • * = match any string
  • ? = match any single character

For example:

# pmlogsearch --host “myhost?.mydomain.com”

matches logs for sessions that ran on myhost1.mydomain.com or myhost2.mydomain.com, but not myhost1 or myhost10.mydomain.com.

# pmlogsearch --host “myhost*”

matches logs for sessions that ran on myhost1.mydomain.com, myhost2.mydomain.com, myhost1 or myhost10.mydomain.com, but will not match anotherhost.mydomain.com.

# pmlogsearch --host myhost11.mydomain.com

only matches logs for sessions that ran on host myhost11.mydomain.com.

--result Returns only events with the indicated result.
--text “<keyword>”

Searches for events where the specified text occurs in the command line or events with keystroke logs that contain the specified text.

You must enter the keyword or phrase as one argument. If the phrase contains a space, enclose the whole phrase in quotes. For example:

# pmlogsearch --text “my phrase”

matches any log containing the string "my phrase".

# pmlogsearch --text phone

matches logs containing any word with the substring phone (such as, telephone, headphones, phones), or the complete word phone.

--no-sort Does not sort the results.
-v | --version Displays the version number of Safeguard and exits.

-h | --help

Displays usage information and exits.

Output

You can output the search results in either human-readable or CSV format.

Human-Readable Output

The following is an example of the human-readable output of a search:

# pmlogsearch --user sheldon --text Linux

pmlogsrvd

Syntax

pmlogsrvd [-d | --debug] [-h | --help] [--log-level <level>] [--no-detach] 
             [--once] [-q | --queue <queue_path>] [--syslog [facility]] 
             [-t | --timeout <delay_seconds>] [-v | --version]

Description

pmlogsrvd is the Safeguard log access daemon, the service responsible for committing events to the Safeguard event log, and managing the database storage used by the event log.

When an incoming event is processed by pmmasterd that event must be logged to the event log. pmmasterd commits a record of the log to the event log queue, which is monitored by pmlogsrvd. pmlogsrvd takes each event from the queue and commits that event to the actual event log.

Options

pmlogsrvd has the following options.

Table 27: Options: pmlogsrvd
Option Description
-d | --debug Enables debug operation. This option prevents pmlogsrvd from running in the background, and enables debug output to both the log and the terminal.
-h | --help Displays the usage information and exits.

--log-level <level>

Controls the level of log messages included in the log file. By default the logging level logs only error messages. Valid logging levels, in ascending order by volume of messages, are:

  • none
  • error
  • warning
  • info
  • debug
--no-detach Do not run in the background or create a pid file. By default, pmlogsrvd forks and runs as a background daemon. When you specify the --no-detach option, it stays in the foreground.
--once Processes the queue once immediately and then exits.
-q | --queue <path> Specifies the location of the event log queue as path.
--syslog Enables logging to syslog.
-t | --timeout <delay_seconds> Specifies the time delay between processing the queue as time seconds. By default pmlogsrvd waits for 120 seconds before waking to scan the event log queue if no other trigger causes it to begin processing. Normally processing is triggered directly by pmmasterd immediately after an event is processed.
-v | --version Displays the version number of Safeguard and exits.
Settings

pmlogsrvd uses the following entries in the /etc/opt/quest/qpm4u/pm.settings file.

Table 28: Settings: pmlogsrvd
Setting Description

eventLogQueue <pathname>

Specifies the location of the event log queue, used by both pmmasterd and pmlogsrvd. This setting is ignored by pmlogsrvd when you use the --queue option on the command line.

pmlogsrvlog <pathname>

Fully qualified path to the pmlogsrvd log file.

syslog yes|no

By default, /pmlogsrvd/fR used this setting to determine whether to send log messages to syslog. When you use the /syslog/fR option on the command line, this setting is ignored.

Files

  • settings file: /etc/opt/quest/qpm4u/pm.settings
