[Oisf-users] Suricata in container

[Barkley, Joey]

I’m using docker and it works really well. We’re hoping to continue tuning to the point where we can run a couple different containers on the same system, but RAM is an issue with the way we have it configured now. Currently using somewhere around 84GB with afpacket and using 16 procs.

Suricata with load balance in one container is working for me, but I still want to configure load balancer server and Suricata in two different container. How

Installing suricata with load balancer server is kind of working for me, but I am not able to see the dropped packet information.

Well just fyi i was talking about containers as in LXC (Linux Containers), without another layer added on it like docker.
Dont know if you can do it with docker, but should be possible, too.

I’m still pretty new to docker (just to be clear) and have not tried this yet-

This is how I am planning to deploy IPS for my HTTP server(s)

HTTP server “exposes” its port to other containers only; (not bound to host port)

IPS container “exposes” port 80 and is bound to the host network. IPS container is started with “—link :httpserv” to perform MITM of the servers traffic.

Dockerfile not included; the commands I expect to run would be:

$ docker run -p 127.0.0.1:12345<http://127.0.0.1:12345/> --name application <http_server_image>
$ docker run -p 80:80 --link application:httpserv --name ips <snort_or_suricata_image>


(YMMV, specifically I’m uncertain of the “—link” option)

From here, it becomes a question of how the IPS container firewall rules are setup (assuming NFQ+daq for my case).
In the example above, I would have to do some sort of NATing (:80 -> 127.0.0.1:12345<http://127.0.0.1:12345/>).

This seems all good; but I still feel like I’m over doing it and that docker may provide a more reasonable
out-of-box magic to ease this further.

________________________________

Otherwise, for passive setups, it should be super easy. Add flags to docker run command: “—net=host —privileged”
(refer to “https://registry.hub.docker.com/u/manell/wireshark/“).

Install suricata in the container where you run the loadbalancer and you catch the traffic.

How can I do so? I want the traffic to flow from internet to load balancer server (running in a container) to Suricata (running in a seperate container) to application server.

If you use that particular container as reverse proxy for example.
