Lilith

Lilith reads in EVE files from Suricata and Sagan into PostgreSQL.

From there that data can then be searched and information on specific events fetched.

Setup

First you need to setup your PostgreSQL server.

createuser -D -l -P -R -S lilith
createdb -E UTF8 -O lilith lilith

Setup /usr/local/etc/lilith.toml

dsn="dbi:Pg:dbname=lilith;host=192.168.1.2"
pass="WhateverYouSetAsApassword"
user="lilith"
# a handy one to ignore for the extend as it is spammy
class_ignore=["Generic Protocol Command Decode"]

# add a suricata instance to monitor
[suricata-eve]
instance="foo-pie"
type="suricata"
eve="/var/log/suricata/alert.json"

# add a second suricata instance to monitor
[another-eve]
instance="foo2-pie"
type="suricata"
eve="/var/log/suricata/alert2.json"

# add a sagan eve to monitor
# instance name is 'foo-lae', given there is no value for instance
[foo-lae]
type="sagan"
eve="/var/log/sagan/alert.json"

Now we just need to setup the tables.

lilith -a create_tables

If using snmpd.

extend lilith /usr/local/bin/lilith -a extend

Config File

The default config file is /usr/local/etc/lilith.toml.

| Variable | Description | |--------------|------------------------------------------------------------------------------------------------------------------------| | dsn | A DSN connection string to be used by [DBI][https://metacpan.org/pod/DBI]. [DBD::Pg][https://metacpan.org/pod/DBD::Pg] | | pass | Password to use for the connection. | | user | User to use for the connetion. | | class_ignore | Array of classes to ignore. |

Sub hashes are then treated as a instance. The following values are available for that.

| Variable | Required | Description | |----------|----------|--------------------------------------------------------------------| | eve | yes | The EVE file to follow. | | type | yes | sagan or suricata, depending on which it is. | | instance | no | The name for the instance. If not specified the hash name is used. |
