Multi Tenancy
|
|
=============
|
|
|
|
Introduction
|
|
------------
|
|
|
|
Multi tenancy support allows for different rule sets with different
|
|
rule vars.
|
|
|
|
YAML
|
|
----
|
|
|
|
In the main ("master") YAML, the suricata.yaml, a new section called
|
|
"multi-detect" should be added.
|
|
|
|
Settings:
|
|
|
|
* enabled: yes/no -> is multi-tenancy support enable
|
|
* default: yes/no -> is the normal detect config a default 'fall back' tenant?
|
|
* selector: direct (for unix socket pcap processing, see below) or vlan
|
|
* loaders: number of 'loader' threads, for parallel tenant loading at startup
|
|
* tenants: list of tenants
|
|
|
|
* id: tenant id
|
|
* yaml: separate yaml file with the tenant specific settings
|
|
|
|
* mappings:
|
|
|
|
* vlan id
|
|
* tenant id: tenant to associate with the vlan id
|
|

multi-detect:

enabled: yes
|
|

tenants:
|
|

|
|
|
|
The tenant-1.yaml, tenant-2.yaml, tenant-3.yaml each contain a partial
|
|
configuration:
|
|
|
|
::
|
|
|
|
# Set the default rule path here to search for the files.
|
|
# if not set, it will look at the current working dir
|
|

|
|
rule-files:
|
|
- rules1
|
|
|
|
# You can specify a threshold config file by setting "threshold-file"
|
|
# to the path of the threshold config file:
|
|
# threshold-file: /etc/suricata/threshold.config
|
|
|
|
classification-file: /etc/suricata/classification.config
|
|
reference-config-file: /etc/suricata/reference.config

# Holds variables that would be used by the engine.
|
|
vars:
|
|
|
|
# Holds the address group vars that would be passed in a Signature.
|
|
# These would be retrieved during the Signature address parsing stage.
|
|
address-groups:
|
|
|
|
HOME_NET: "[192.168.0.0/16,10.0.0.0/8,172.16.0.0/12]"

Unix Socket
|
|
-----------
|
|
|
|
Registration
|
|
~~~~~~~~~~~~
|
|
|
|
register-tenant <id> <yaml>
|
|
|
|
Examples:
|
|
|
|
::
|
|
|
|
register-tenant 1 tenant-1.yaml
|
|
register-tenant 2 tenant-2.yaml
|
|
register-tenant 3 tenant-3.yaml
|
|
register-tenant 5 tenant-5.yaml
|
|
register-tenant 7 tenant-7.yaml
|
|
|
|
unregister-tenant <id>
|
|
|
|
::
|
|
|
|
unregister-tenant 2
|
|
unregister-tenant 1
|
|
|
|
Unix socket runmode (pcap processing)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The Unix Socket "pcap-file" command can be used to select the tenant
|
|
to inspect the pcap against:
|
|
|
|
::
|
|
|
|
pcap-file traffic1.pcap /logs1/ 1
|
|
pcap-file traffic2.pcap /logs2/ 2
|
|
pcap-file traffic3.pcap /logs3/ 3
|
|
pcap-file traffic4.pcap /logs5/ 5
|
|
pcap-file traffic5.pcap /logs7/ 7
|
|
|
|
This runs the traffic1.pcap against tenant 1 and it logs into /logs1/,
|
|
traffic2.pcap against tenant 2 and logs to /logs2/ and so on.
|
|
|
|
Live traffic mode
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
For live traffic currently only a vlan based multi-tenancy is supported.
|
|
|
|
The master yaml needs to have the selector set to "vlan".
|
|
|
|
Registration
|
|
~~~~~~~~~~~~
|
|
|
|
Tenants can be mapped to vlan id's.
|
|
|
|
register-tenant-handler <tenant id> vlan <vlan id>
|
|
|
|
::
|
|
|
|
register-tenant-handler 1 vlan 1000
|
|
|
|
unregister-tenant-handler <tenant id> vlan <vlan id>
|
|
|
|
::
|
|
|
|
unregister-tenant-handler 4 vlan 1111
|
|
unregister-tenant-handler 1 vlan 1000
|
|
|
|
The registration of tenant and tenant handlers can be done on a
|
|
running engine.
