OSSIM 3.1 (AlienVault) + SNARE (snarewindows) Configuration Howto

gkoo — Fri, 09 Mar 2012 16:47:37 +0000

I’ve recently had to deploy an OSSIM installation and had a very hard time dealing with the SNARE integration. The documentation provided by ossim is very scattered and imprecise. These are the steps I’ve followed to get SNARE integrated in OSSIM.

Install OSSIM on the server. Have a Windows machine ready to test this out.

Follow this guide to install SNARE on windows and to activate the SNARE plugin on the server. When u get to the part where it says “That’s all. Now you can view the Windows events at the framework.”, if you encouter the same issues i did you will be surprised that nothing actually shows in the OSSIM web interface. To fix that do the following:

Make sure you configure snare to use “;” as a log delimiter. To do that use the following instructions:

Windows uses by default the space character to separate the different fields in the
log, you will need to change this delimiter and use “;” to allow AlienVault collecting
events.
This delimiter can be changed in the Windows registry using the regedit tool.
HKEY_LOCAL_MACHINE/SOFTWARE/InterSect Alliance/AuditService/Config/Delimiter

After changing the delimiter you will need to restart the Snare Service.

Go to your snare interface on the Windows machine ( http://localhost:6161) – go to Network Configuration and make sure that:

Destination Snare Server address
Destination Port

If you followed the above mentioned pdf guide right the other SNARE parameters should be right.

At this point you can start logging in and out of the Windows machine and that should show up in your server in the syslog ( tail -f /var/log/syslog ). If that is the case than you’re almost done

A bit of theory (if you didn’t have the time to read the ossim documentation) for you to understand how things work with ossim plugins, specifically SNARE here. The snare gathers the logs from the Windows machine and sends them to your server’s syslog. From there the ossim-agent reads the syslog, parses it and when it matches a row, normalizes it and sends it to the ossim-server which stores it in the database and displays it on the interface. ( please correct me if I’m wrong).

The issue that i had was that the default snare.cfg ( /etc/ossim/agents/plugins/snare.cfg) didn’t have the right regex rules configured in it by default and thus was not matching anything from the syslog.

After replacing the original snare.cfg with the one i found here and restarting the ossim-agent the windows events started showing up in the web interface.

Hope this helps, it took me 3 days and 2 sleepless nights to figure this out. Feel free to ask any questions related to this post.

Exec format error (in linux cron)

Exec format error (in cron)

If you are like me, you sometimes get lazy and forget to include the shell command at the top of your scripts. This usually isn’t a problem, but in certain cases (where the shell isn’t set, or doesn’t exist yet) it will cause problems. So, even if your script is set to be executable (chmod +x), you’ll receive an error like:

Exec format error

Just such a case manifests itself when using a script through cron (and run-parts). To remedy this problem put the following at the beginning of the script:
#!/bin/sh

That way, the system will know what to use when executing the script.

To be able to use a Canon multifunctional to scan over network you need the MF Network Scan Utility.

Here’s a link to download the original installation CD which contains this utility:

I ran into this issue when configuring zabbix on a long night. Maybe because i was too tired to notice on the client i was editing the server information in /etc/zabbix/agent.conf instead of /etc/zabbix/agentd.conf which is the config file for the daemon.

Edit the right file and you’ll get rid of this error.

If you have the Microsoft Office 2007 Small Business MLK (medialess kit) and no discs are included you should go to microsoft’s website to download it but their page doesn’t work. I called their support team and here is the link to directly download the Microsoft Office 2007 Small Business and re-install it using your license. It will save you precious time.

OpenWrt Openswan error: rm: invalid option –d

gkoo — Thu, 26 May 2011 20:53:26 +0000

If you find yourself having this error when starting ipsec on openwrt:

ipsec_setup: Starting Openswan IPsec U2.6.29/K2.6.32.25…
ipsec_setup: rm: invalid option — d
ipsec_setup: BusyBox v1.15.3 (2010-11-11 22:22:00 PST) multi-call binary
ipsec_setup: Usage: rm [OPTIONS] FILE…

you can easily fix it by editing the following file: /usr/lib/ipsec/_realsetup and on line 293 change:

rm test -d `echo $subsyslock | sed -r ‘s/(^.*\/)(.*$)/\1/’` “&&” touch $subsyslock “&&”

to rm test -rf `echo $subsyslock | sed -r ‘s/(^.*\/)(.*$)/\1/’` “&&” touch $subsyslock “&&”

OpenWRT + OpenSwan IPSEC on Linksys WRT54GL v1.1

gkoo — Wed, 18 May 2011 16:53:12 +0000

First of all u need a linux pc in order to accomplish this so if u don’t have one try using a virtual machine running linux.

Ok here goes,
The challenge was to install openswan ipsec support on top of the openwrt custom firmware using a Linksys WRT54GL router. The usual way to do this would be using the package manager that comes with OpenWRT (opkg) but since this router has only a 4MB flash, if using the default firmare from openwrt, there’s not enough space to install openswan. The way to do it is to build a custom firmware using OpenWrt’s Image Builder.

The instructions on how to use the builder can be found here:
http://wiki.openwrt.org/doc/howto/obtain.firmware.generate

The issue i had is that it’s quiet confusing to understand which packages to use for a custom firmare. The article in the link above shows us how to get a list of the default packages coming with the official firmare:

After a few times trying i ended up with the following make command to generate a firmware that would fit in the 4mb flash card on the router. I had to drop some of the default packages (the ones with a – in front of their name in the below command) in order to keep the firmare + web gui + openswan configuration:

make image PACKAGES=”base-files busybox dnsmasq dropbear firewall hotplug2 libc libgcc nvram uci udevtrigger wireless-tools luci kmod-crypto-core kmod-crypto-aes kmod-crypto-arc4 kmod-ipt-core kmod-ipt-conntrack kmod-ipt-nat kmod-ipt-nathelper -kmod-ppp -kmod-pppoe kmod-crc-ccitt kmod-diag kmod-switch kmod-b43 kmod-b43legacy kmod-cfg80211 kmod-mac80211 libiptc liblua libnl-tiny libuci libuci-lua libxtables crda iptables iptables-mod-conntrack iptables-mod-nat iw -ppp -ppp-mod-pppoe uhttpd wpad-mini -lua openswan -nano mtd -opkg”

Note the openswan package at the end. When issuing this command the system will build the custom firmware which is under 4mb so it will fit your router’s flash. You can then upload the firmare onto the router using tftp as described here: http://wiki.openwrt.org/toh/linksys/wrt54g

Good luck

IPSEC Openswan “probable authentication failure” using PSK shared keys

gkoo — Sat, 16 Apr 2011 16:02:03 +0000

I was getting this error and i had to surf the internet for 5 hours until i figured out the issue myself. I thought this might save others precious time. So the error i was getting in the server was looking like this:

Apr 16 18:47:20 vpn pluto[6294]: “test2″ #1: probable authentication failure (mismatch of preshared secrets?): malformed payload in packet
Apr 16 18:47:20 vpn pluto[6294]: | payload malformed after IV
Apr 16 18:47:20 vpn pluto[6294]: | b3 39 dc a6 a7 2a 59 0f d9 06 4b 7f 4a ed 0f 7a
Apr 16 18:47:20 vpn pluto[6294]: “test2″ #1: sending notification PAYLOAD_MALFORMED to 81.141.210.226:500

On the client side i was getting:

010 “test2″ #1: STATE_MAIN_I3: retransmission; will wait 40s for response
003 “test2″ #1: Informational Exchange message must be encrypted
003 “test2″ #1: discarding duplicate packet; already STATE_MAIN_I3
031 “test2″ #1: max number of retransmissions (2) reached STATE_MAIN_I3. Possible authentication failure: no acceptable response to our first encrypted message

I made sure there are no typos in ipsec.secrets but in the end I figured out the issue.
You have to have a new blank line after the PSK declaration in ipsec.secrets otherwise the system doesn’t recognize it. Hope it helps.

You might get the following error:

AppName: outlook.exe AppVer: 11.0.5510.0 AppStamp:3f1380f0
ModName: mso.dll ModVer: 11.0.5606.0 ModStamp:3f334cce
fDebug: 0 Offset: 0001f7b8

The only solution that worked for me was to delete C:\Documents and Settings\\Application Data\Microsoft\Outlook\outcmd.dat

This file stores some settings in outlook that you can redo after your program starts in normal mode.

Good luck
