RE: Updating Snort Signatures In Stable ? -- SNORT 1.9.0 for woody

2002-12-30 Thread Sébastien Desse
Hello,

I saw a lot of discution about snort 1.9 on woody.
I just whant to tell that we do need the 1.9 !
why don't we use an another directory (like contrib) where we can put
unstable softwares built for the stable distribution ?

For those who are interested in snort 1.9 without using unstable and without
last glibc and uploaded it to a website : http://acdessec.chez.tiscali.fr/

Please email me if you find bugs in these packages.

Regards,

Sebastien Desse

 Unstable glibc is a bad idea, i known.But and about unstable snort? One

unstable snort is unavoidable, since, as has been discussed, it is important
to have the latest snort signatures, and those often require the latest
version of snort.

 Yeah - I thought there was a big problem with installing any unstable
 *binary* on a stable box, for exactly that reason.

Yep.  But there's often no need, since many (most?) source packages
testing/unstable can be compiled on stable.

 I too don't want the unstable glibc - surely it means you have to replace
 just about every other binary on the system ?

Programs built with glibc x.y will run on glibc x.y+d, though the reverse is
not generally true.  So, upgrading glibc does not typically present problems
with existing programs.  There are exceptions, of course, for example the
recent glibc 2.3 transition problems (mostly due to programs inappropriately
using internal glibc interfaces), a good reason not to upgrade glibc
unnecessarily.

Yes. See below.

No, you can't. There are changes in the signature definition that
will only work with the unstable version (sid's) and will not work in
woody.

For the moment, the only think you can do is download sid's
package for snort and compile it in a woody system. This is easier than
you might think since it has proper Build-Depends so you might need only
to point apt to the sid sources and ask it to download the source and
--compile it.

I have done this successfully in a woody box and could probably
post the compiled packages somewhere if anyone is interested (but cannot
compromise to recompile for woody each time a new version is available in
sid).

This is a known issue (it also affects antivirus) and has been
debated at length in debian-devel. You might want to search the archive
for more information.

 Thanks for _any_ comments at all.

Well, the version I am running at this time is Version 1.9.0 (Build 209)
and was downloaded from snort.org. 

My friend was kind enough to write a script that downloads signatures for
this version from the snort site... This script alters the snort.conf file
to include any new rulefiles and restarts snort if nessicery...

I find this script very usefull and use it in combination with cron...
Anyhow: this is the script located @ www.xssass.be...

Well thanks for the answers folks - it seems clear (especially after
checking http://www.snort.org/dl/rules/, which says If you are using
a version before 1.9.x, please upgrade) that I should stop using the
Debian stable V1.8.4 package and switch to hand-built V1.9.0 made from
source - and I'll gladly grab Kristof's signature update script and
adapt to my needs (thanks for that).

[I hope my current MySQL and Acidlab backend works with the later
Snort - I guess I'm about to find out ..]

I'd suggest maybe a note about V1.8.4 being useless should be added
to http://packages.debian.org/stable/net/snort.html, along with some
advice about getting signature updates (i.e. roll your own).

IIRC important new versions of existing packages are allowed into
point releases, so maybe Woody's main Snort engine binary packages can
be updated when 3.0r1 happens.

And I still think it'd be nice if we could find a way to package up
and push out stable signature updates - but I can see why that would
be difficult to set policy for.

Yes. See below.

No, you can't. There are changes in the signature definition that
will only work with the unstable version (sid's) and will not work in
woody.

For the moment, the only think you can do is download sid's
package for snort and compile it in a woody system. This is easier than
you might think since it has proper Build-Depends so you might need only
to point apt to the sid sources and ask it to download the source and
--compile it.

I have done this successfully in a woody box and could probably
post the compiled packages somewhere if anyone is interested (but cannot
compromise to recompile for woody each time a new version is available in
sid).

This is a known issue (it also affects antivirus) and has been
debated at length in debian-devel. You might want to search the archive
for more information.

Why couldn't one just use the version from unstable (presumably building it
from source)?

Updating Snort Signatures In Stable ?

2002-12-05 Thread Nick Boyce
I've been running Snort for a month or so now on a Woody box at work,
and am now wondering whether the Debian Project (or packager) has a
Plan for providing signature file updates to users of the stable
distribution.

The snort-rules-default package available in stable never gets updated
- nor would we normally expect it to unless a security vulnerability
arises - but obviously IDS signatures must be kept up to date on a
*timely* basis, just like antivirus package signatures, for the
package to be fully effective.

I don't intend any criticism, but do wonder what we're expected to do
about this - download fresh signatures straight from www.snort.org ?

If so, are there any special steps required to integrate such a
download into our Debian Woody system ?

Alternatively, I note there are later signature packages in testing
and unstable - can we use those on a Woody system ?

I searched the debian-security archive but didn't hit any items
discussing this, so maybe it's a dumb question - sorry, I'm a newb
here.

Thanks for _any_ comments at all.

This has been discussed before.  The thing is, I think that if you're
serious about using snort, you should not even consider using the one in
Debian.  snort.org doesn't even distribute up-to-date rules files for
the version in stable.  So if you want to have a useful ruleset, you

you need to get a new version from snort.org.  Either way, you're
working outside the Debian system.

There have been proposals for the creation of a dynamic section of the
Debian distribution to contain data that frequently changes.  However,
in the case of snort, where the new data may well not work with the old
software, this doesn't help.  Really, I don't think snort should be
packaged in Debian at all.  It's one of those things that needs to be
current in order to be useful, and we just can't provide that.
Providing an ineffective version is doing a disservice to our users,
since it provides them with incorrect data (e.g. by telling them that
there are no known vulnerabilities on the machines they scan).
