RE: Snort-users digest, Vol 1 #3309 - 9 msgs

I have recently installed snort with snortcenter and the ACID management
console on a dual pIII 500 system with a gig of ram and pretty good network
cards (Intel gigabit and 100 Mb). The box is acting as a bridge and im
filtering the incoming traffic with IPCHAINS. Im interested in both whats
going on on the inside (!) and the outside of my network. This is an
excellent tool. I have 2 quick questions

1) When snort reports that packets are dropped, should I take that to mean
that they are dropped on the floor or just that Snort couldt look at them
fast enough so it skipped them? I want to montior traffic, but not at the
expense of packet loss.

2)I have a LAN on one side of this box with about 100 clients and a
connection to a gig E backbone on the other side. Is my snort box
configuration reasonable? Should I be droppping packets consistently?

Hhhmm.. hope this is what you were asking for:

Go to Resources -> Variables -> View Variables

Edit "HOME_NET", change the value and click on "Duplicate"

Now you have more than one HOME_NET defined.

Go to Sensor Config -> Variable Selection

Pick the sensor you want, activate the new HOME_NET.

Then just push your new rules to the sensor and reaload it.

Cheers,
Rodrigo

How is Home_Net defined when using SnortCenter.

I have installed acid and snortcenter and based on the install process how
do you specifically define your home_net in snortcenter?  I know how to
manually do it but how do you do it in snortcenter?

You could do that, or...

<ShamelessPostgreSQLPlug>

you could use PostgreSQL, compiled with the --with-openssl option, and
use ssl natively and bypass stunnel altogether.  The PostgreSQL
installation/configuration documentation explain how to set this up.

Hi,
=20
=20
i would to encrypt the barnyard connection to the the mysql=20
database.
-is this possible over stunnel?
This works just fine for me without any issues.
You can run Stunnel with certificates and strict cert checking.
=20
On the snort-box do something like
stunnel -c -d 127.0.0.1:3306 -r mysql-server-here:3307 -s stunnel -g
stunnel
=20
and on the remote mysql box
/usr/sbin/stunnel -p /usr/share/ssl/stunnel/server.pem -P/tmp/ -d 3307
-r 127.0.01:3306 -s stunnel -g stunnel
=20
or, with strict cert checking, something like this on the client
/usr/sbin/stunnel -c -d 127.0.01:3306 -r=20
mysql-server-here:3307 -v 3 -A
/usr/share/ssl/stunnel/server.cert -p=20
/usr/share/ssl/stunnel/client.pem
-P /var/run/stunnel.pid -s stunnel -g stunnel
=20
on the remote mysql box
/usr/sbin/stunnel -A /usr/share/ssl/stunnel/all.cert -p
/usr/share/ssl/stunnel/server.pem -d 3307 -r 127.0.0.1:3306 -v 3 -P
/var/run/stunnel.pid -s stunnel -g stunnel
=20
Now, if you distribute the proper certs to the client and the server,
your connection is ssl-encrypted and connections are allowed with the
proper certs only.
=20
Works like a charm for me.
=20
Oh, it's very possible I goofed up on the pasted lines, you=20
gotta check
the parameters of course ;)

Try looking into IDScenter and Eagle X from Engage Security.

Hello.  I'm not sure if this is a support mailing list but hopefully
someone could help me out.

I am relativly new to Snort and it looks very decent for what I need it
to do.  I am running snort on a win32 machine.  My problem is that I
need snort to send either an email, which doesn't look possible as I am
not a programmer, or an SMB message to a selected workstation.  My
problem is that SMB doesn't seem to be compiled into the windows
binaries and there doesn't seem to be another way to configure it
without the 'configure' executable.  Any help would be appreciated.

Mike.

Has anyone seen anything like this before?  It doesnt look like the
translate:
f vuln [0], except that it contains the translate: f header.  The long
string
of gobbley-gook after the auth: negotiate looks suspicious to me, but what
do I know?  I looked through the IIS 'sploits at bugtraq and didnt see
anything
that matches.  Is this valid traffic?

You can go to www.winsnort.com <http://www.winsnort.com/>  and go to the
Documentation section and check out the docs as it has a section on
installing Email support for Windows.

I am relativly new to Snort and it looks very decent for what I need it to

snort to send either an email, which doesn't look possible as I am not a

Well, sending an email from within snort is absolutely impossible, even if
you are a programmer. Snort needs to be very very very fast (ie: 1/1000th
of a second delay has a HUGE impact on performance). If it goes off and
generates network connections, launches programs, etc, it will miss a large
quantity of traffic, creating a very effective way for attackers to sneak
past your snort sensor by only generating one alert that causes email.

Really, I'd suggest using something like acid for your logging and alerting
needs if you're restricted to the win32 platform. Emails, smb alerts, etc
are really best done with an external program so that snort isn't wasting
time babysitting a network messaging protocol.

Hello,

That's quite correct.

Well, the Catalyst 2950 and 3550 boxes for example do SPAN with wire-spee=

regardless  of  which  port  is  actually  source  port,  and  which one =

Indeed. It's just a question of detailed documentation available (includi=

Subject: [Snort-users] snortcenter 1.0RC1


there are a few bugs with the snortcenter 1.0-RC1 that I'm experiencing...
is this program even "active"...I noticed the last update with 2002-05-14.


the most painful bug is I have to deactivate rules manually,
the select all works but the "do with selected" doesn't :(

it looks like a great product, but I don't know if
it's something I can show off to the boss, if it's a
year plus out of date.

I also have the same problem:

I've done the following modifications in scan.rules:


pass tcp $EXTERNAL_NET any -> $HOME_NET 3128

alert tcp $EXTERNAL_NET any -> $HOME_NET 3128 (msg:"SCAN Squid Proxy
attempt"; flags:S,12; classtype:attempted-recon; sid:618; rev:4;)


and still got the alert in ACID (with last snort tarball from CVS).

It's normal ?
How can I use pass rules.

Just on the off chance...  Make sure you're using "-o" on the command
line.  If not pass rules be processed after alert rules.

Cheers!
