u2eve - Unified2 to Suricata eve events

Read unified2 log files and output events as Suricata EVE JSON (or as close as possible).

Usage

System Message: ERROR/6 (/home/docs/checkouts/readthedocs.org/user_builds/idstools/checkouts/latest/doc/tools/u2eve.rst, line 9)

Command ['../bin/idstools-u2eve', '--help'] failed: [Errno 2] No such file or directory: '../bin/idstools-u2eve'

Example - View a unified2 file as eve

idstools-u2eve -C path/to/classification.config \
  -S /path/to/sid-msg.map \
  -G /path/to/gen-msg.map merged.log.1431384519

Example - Continuous conversion to eve

idstools-u2eve --snort-conf /etc/snort/etc/snort.conf \
    --directory /var/log/snort \
    --prefix unified2.log \
    --follow \
    --bookmark \
    --delete \
    --output /var/log/snort/alerts.json \

The above command will operate like barnyard, reading all unified2.log files in /var/log/snort, waiting for new unified2 records when the end of the last file is reached.

Additionally the last read location will be bookmarked to avoid reading events multiple times, the unified2.log files will be deleted once converted to JSON, and JSON events will be written to /var/log/snort/alerts.json.

Configuration File

A configuration file is simply a file containing the command line arguments, one per line with an ‘=’ separating the name from the argument. For example, to save the arguments used in example 2 above:

--snort-conf=/etc/snort/etc/snort.conf
--directory=/var/log/snort
--prefix=unified2.log
--follow
--bookmark
--delete
--output=/var/log/snort/alerts.json

Then call idstools-u2eve like:

idstools-u2eve @/path/to/config-file

Addtional arguments can also be provided like:

idstools-u2eve @/path/to/config-file --stdout
