Suricata 2.0beta2 as IPS on Ubuntu 12.04

Today I decided to install Suricata, cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 open source intrusion detection and prevention engine from cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 Open Information Security Foundation (OISF), as an IPS.

I've been running Suricata in IDS mode through Security Onion on and off for several years, but I never tried Suricata as an IPS.

I decided I wanted to run Suricata as a bridging IPS, such that it did not route traffic. In ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r words, I could place a Suricata IPS between, say, a router and a firewall, or between a router and a host, and neicá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r endpoint would know cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 IPS was present.

Looking at available documentation across cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 Web, I did not see specific mention of this exact configuration. It's entirely possible I missed something useful, but most people running Linux as a bridge weren't using Suricata.

Those running Linux as a bridge sometimes enabled an IP address for cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge, which is something I didn't want to do. (True bridges should be invisible to endpoints.)

Of course, to administer cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge system itself, you ensure cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 box has a third interface and you assign that interface a management IP address.

I also noticed those using Suricata as an IPS tended to configure it as a router, giving IP addresses to cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 internal and external IP addresses. I wanted an invisible bridge, not a router.

The hardware I used for cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge was a 2003-era Shuttle small form factor system with 512 MB RAM, two NICs (eth0 and eth1), and a wireless NIC (wlan0). I installed Ubuntu Server 12.04.3 LTS. I tried installing cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 64 bit version but realized cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 box was too old for 64 bit. Once I tried a 32 bit installation I was working in no time.

The first step I took was to create cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge. I wanted to deploy cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 system between a router and an endpoint with IP address 192.168.2.142, like this:

router <-> eth0/Linux bridge/eth1 <-> 192.168.2.142

These are cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 commands to create cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge. This how-to was useful.

$ sudo apt-get install bridge-utils
$ sudo brctl addbr br0
$ sudo brctl addif br0 eth0
$ sudo brctl addif br0 eth1
$ sudo ifconfig eth0 0.0.0.0
$ sudo ifconfig eth1 0.0.0.0
$ sudo ifconfig br0 up

With cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge working, I could reach 192.168.2.142, cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 endpoint host, through cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 Ubuntu Linux bridge system. If I wanted to, I could watch traffic with Tcpdump on br0, eth0, or eth1.

Next I needed to install Suricata. I decided to use cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 beta packages published by OISF as described here. I also had to install python-software-properties as shown in order to have add-apt-repository available.

$ sudo apt-get install python-software-properties

$ sudo add-apt-repository ppa:oisf/suricata-beta

Next I added cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 following test rule to /etc/suricata/rules/drop.rules. The file location is arbitrary. I wrote a simple rule to alert on ICMP traffic from a test system, 192.168.2.126. All of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 following is one line. I just broke it for readability.
alert icmp 192.168.2.126 any -> any any (msg:"ALERT test ICMP ping from 192.168.2.106";
 icode:0; itype:8; classtype:trojan-activity; sid:99999998; rev:1;)

Notice I have no iptables rules loaded at this point:

$ sudo iptables -vnL
Chain INPUT (policy ACCEPT 5 packets, 392 bytes)
 pkts bytes target     prot opt in     out     source               destination 

Chain FORWARD (policy ACCEPT 4 packets, 240 bytes)
 pkts bytes target     prot opt in     out     source               destination 

Chain OUTPUT (policy ACCEPT 4 packets, 496 bytes)
 pkts bytes target     prot opt in     out     source               destination

Now I was ready to see if Suricata would at least see and alert on traffic matching my ICMP test rule. First I started Suricata and told it to watch br0, cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge interface.

$ sudo suricata -c /etc/suricata/suricata.yaml -i br0

I don't care about cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 Warning or Error notices here. I could fix those but cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y are not germane to demonstrating cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 main point of this post.

On a separate system, 192.168.2.126, I pinged 192.168.2.142.

$ ping -c 2 192.168.2.142

Then I checked my Suricata logs:

That worked as expected. I got alerts on cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 ICMP traffic matching cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 test ALERT rule.

Now it was time to drop traffic!

I added a new rule to drop.rules, again broken only for readability here:

drop icmp 192.168.2.126 any -> any any (msg:"DROP test ICMP ping from 192.168.2.106";
 icode:0; itype:8; classtype:trojan-activity; sid:99999999; rev:1;)
I also disabled cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 previous ALERT rule by commenting it out.

Next I added iptables rules for cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 FORWARD chain, for traffic traversing cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge. This Documentation was helpful.

$ sudo iptables -I FORWARD -j NFQUEUE

$ sudo iptables -vnL
Chain INPUT (policy ACCEPT 32 packets, 2752 bytes)
 pkts bytes target     prot opt in     out     source               destination 

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain OUTPUT (policy ACCEPT 25 packets, 2600 bytes)
 pkts bytes target     prot opt in     out     source               destination 
Finally I restarted Suricata, this time telling it to use queue 0, where NFQUEUE was waiting for packets for Suricata.
$ sudo suricata -c /etc/suricata/suricata.yaml -q 0
25/1/2014 -- 22:54:49 -  - This is Suricata version 2.0beta2 RELEASE

With Suricata running in IPS mode, I tried pinging 192.168.2.142 from 192.168.2.126 as I did earlier.
$ ping -c 2 192.168.2.142

So that's it.

Note that with this configuration, if you stop Suricata cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365n cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 host it's "protecting" is totally unreachable. You can restore connectivity by flushing cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 iptables rules via this command:

$ sudo iptables -F
Now cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 endpoint is reachable while Suricata is not running. To re-enable cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 IPS, you have to set up cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 NFQUEUE via iptables again as shown previously.

Following cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365se directions you have cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 foundation for building a bridged IPS using Suricata on Ubuntu Server 12.04. The next step would be to fix cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 configuration issues causing cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 start-up error messages, make cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 bridge, firewall, and Suricata components available at start-up, and cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365n build your own set of DROP rules. There are probably also optimizations for PF_RING and ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r performance features. Good luck!

Do you run Suricata as an IPS? How do you do it? Have you tried cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 new 2.x beta?

I am personally interested in OISF because I think cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y bring a level of enthusiasm, openness, and innovation to cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 open source network security monitoring space, alongside tools like Bro and Snort and ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365rs I mentioned in my January post Seven Cool Open Source Projects for Defenders.

OISF is also a US nonprofit, a 501c(3) group, so I like cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 idea of helping that sort of organization.

Notes from OISF Meeting in DC

This month I was pleased to attend a public meeting of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 Open Information Security Foundation in Washington, DC. I got a chance to meet several people I have known for many years through cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir work with Snort, such as Matt Jonkman, Will Metcalf, Victor Julien, Frank Knobbe, and two guys from a federal agency that have extended Sguil way beyond what I knew anyone was doing! The group posted DC Brainstorming Meeting Notes, but I wanted to record a few thoughts here.

OISF is a US nonprofit, a 501c(3). Their goal is to produce a new network inspection and filtering engine (IDS/IPS) that will be released under GPLv2. They can not and will not commercialize, sell, patent, copyright, or profit from cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 engine. Racá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r, ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365rs who participate in cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 OISF Consortium (listed on cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir Web site) are donating coders, equipment, and financial support in exchange for cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 ability to commercialize cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 engine.

OISF works with cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 Open Source Software Institute, famous for getting FIPS validation for OpenSSL -- something everybody wanted but no one wanted to fund alone. OISF is part of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 DHS Homeland Open Security Technology (HOST) program. OISF has received legal guidance from cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 Software Freedom Law Center.

OISF has many goals for cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir engine, outlined in cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 notes I linked earlier. Most interesting is cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir goal for a production release by cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 end of this year. If cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y are to make this goal, I think cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 project needs to severely limit cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 requirements for cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 first release. I would focus on cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 following.

  • Developing cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 rules language.

  • Implementing IPv6.

  • Implementing multi-threading.


Those three tasks are monumental, but cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y would immediately differentiate OISF from ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r options. There is talk within cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 project of semi-Snort compatible output, so you might send OISF data to a file in Snort Unified or Unified2 format to be read by Barnyard or Barnyard2.

As it develops I will discuss it here.
