flaim - anonymize system and network logs
flaim [ OPTION ]
[ -m module-name ] [ -p policy ] [ -i input.log ] [ -o output.log ]
flaim is a multi-level, multi-log anonymization
tool. FLAIM-Core comprises the anonymization engine and XML based policy
manager. FLAIM-Core loads dynamic libraries responsible for I/O and parsing
at runtime. There is a library for each type of log flaim supports. The
XML policy, the I/O module, input file and output files are all specified
on the command line.
- -h --help
- Display the usage information and exit.
- -i --input <file-name>
- Specifies the source log for anonymization. If unspecified,
stdin will be used. However, not all modules support reading input from
stdin. Those that do not support streaming will exit and force you to specify
a file name.
- -l --list
- Lists all installed modules. FLAIM will not find manually
installed modules in non-standard locations.
- -m --module <module-name>
- Load the
specified parsing module. The -l option shows the valid choices. Either this
option must be used to specify a module installed in the default location,
or the -M option must be used.
- -M --moduleLib <module-lib-path>
- Load the module
library from the given path. This option is mutually exclusive with -m and
used for explicitly specifying the module location. It is also necessary
to specify the schema location using -s when using this option.
- -o --output
<file-name>
- Specifies the destination file for anonymized data. If unspecified,
stdout will be used. However, not all modules support writing output to
stdout. Those that do not support streaming, will exit and force you to
specify a file name.
- -p --policy <file-name>
- The use of this flag is mandatory
as it specifies the location of the user policy.
- -s --schemaModule <module-schema-file-path>
- Load the module schema from the file specified with this option. This option
is used if and only if the -M option is used.
- -v --verbose
- Print verbose messages
to stderr.
- -V --version
- Print version information to stderr and exit.
- -x --xtraConfig
<file-name>
- This is used to specify a file containing extra information to
be passed to the parsing module. It is optional and ignored by most modules.
The environment variable FLAIM_ROOT specifies the location of
flaim and, consequently, the location of the FLAIM modules. This environment
variable is setup in the default installation of FLAIM-Core.
FLAIM
outputs error messages to STDERR and informational messages to STDOUT (Or
course, we cannot enforce this behavior in third party modules). Sometimes
a module will either be unable to parse a packet properly, or it will come
across a corrupted record. Every effort is made to continue, but sometimes
records are corrupted badly enough that re-synchronization is impossible.
In this case, FLAIM must exit without completing the task.
If the corruption
isn’t bad or FLAIM just isn’t able to fully parse the record (e.g., because
it has come across an obscure IP protocol), FLAIM will continue processing
records while writing the troublesome records to an error file. The naming
convention for this file is lib<module_name>_flaim.errors. This file will contain
a subset of the records from the original log, namely, the troublesome
records. If the records are not too corrupted, one should be able to process
this error file with the same tools they would process the original log.
For example, the error file created by the pcap module should be something
that tcpdump can process.

This is a beta release of flaim and we expect bugs to be found. We
suggest users that want to hear about latest bug findings (or submit bugs
themselves) to join the flaim-users@ncsa.uiuc.edu mailing list.
