RAV AntiVirus for Qmail

2001-06-25 Thread Mihai Serban

Dear Qmail users,
GeCAD Software is glad to announce you the last release of
RAV AntiVirus for Mail Servers: http://www.ravantivirus.com
The product is available for: Linux, FreeBSD, OpenBSD.

Subject: 
1. RAV AntiVirus for Mail Servers new release 
2. Protect critical company data! 
3. Improve your ISP services! 
4. Make RAV work your way! 
5. New and flexible licensing scheme! 
6. Update services 
7. Our technical support is here for you! 
8. Discussion lists and info 

1. RAV AntiVirus for Mail Servers protects your e-mail stream directly 
from the mail server. It doesn't matter in which format type the 
messages are sent and received, or how many attachments they have: 
deep down in your Mail Server, RAV AntiVirus will be watching, 
detecting and removing all threats. 

2. Protect critical company data! 
Defend your critical data from viruses before they can penetrate and 
spread in your company! Big corporations with demanding security 
policies and small companies with limited budgets can both protect 
their internet traffic at a proper cost. No matter the size of your 
company you can acquire different packages, depending on your needs of 
protection. 

3. Improve your ISP services! 
RAV AntiVirus is the perfect solution for the ISP's Mail Servers, which 
are dealing with heavy traffic and large amount of clients. RAV 
AntiVirus can improve the services to your customers by scanning the 
email flow and add protection against viruses for the domains hosted, 
allowing you to purchase security on a growing basis through a special 
acquisition program. 

4. Make RAV work your way! 
RAV AntiVirus for Mail Servers is flexible and scalable, allowing 
independent configuration of the scanning module, fully independent 
from the Mail Server. In the configuration file you can customize the 
actions to be taken by RAV when detecting a virus - clean, rename, 
delete, ignore - and benefit of advanced features, like warning the 
sender, warning the target or warning a third party (for example server 
administrator) when detecting an external threat. Also, all the 
messages generated by RAV AntiVirus can be edited to fit your language 
and the security policy of your company. 

5. New and flexible licensing scheme! 
The more you buy - the less you pay for each internet domain! RAV 
AntiVirus for Mail Servers can be purchased through an exceptionally 
scalable Licensing Program, with a special price depending of the 
number of domains protected by RAV and unlimited number of mailboxes. 
You can buy the number of licenses that suites you better, and, in time, 
as your company grows, you can acquire additional licenses.  The 
Licensing scheme includes 1 year Free Updates and full technical 
support. 

6. Update services! 
When purchasing a RAV product, the license includes one year Updates. 
The Updates includes: 
- new virus signatures 
- engine extensions 
- completely new versions of the product 
- availability of the technical support services 
By purchasing the update you will always have the latest version of the 
product, with the most up to date virus signature database. 
You can extend the update services by purchasing Update Extension at 
only 20% of the product value per annum! 

7. You are not alone - our technical support is here for you! 
RAV AntiVirus Desktop license includes Technical Support by: 
- e-mail; 
- phone support, 24 x 7 x 365, offered by your local distributor or by 
GeCAD Software; 
- participating to specific Discussion Lists. 
- You can even have a Personal Technical Advisor at your disposal for an 
additional fee. 

8. We invite you to join  our discussion lists:

You can try the McAfee anti-virus 4.14.0 with AMaVis+qmail packages.
I use it on every server I build, and works wonderfully.
And for DAT update, just build a little bash script, powered by wget ;)

 Um, ISTR that the Morris Worm did a pretty good job of spreading over

The worm did not infect more than 10 % of all hosts. This estimate is
based on the extrapolation of the number of infected hosts at MIT. A poll
done by people at Harvard suggests the actual number for all Internet
hosts may have been considerably smaller, approx. 1,000-3,000 hosts out of
60,000, i.e. 2-5 %. Unfortunately, one can only guess how many of those
hosts were unix-like machines. Anyway, the numbers is not very impressive
compared to what could be accomplished with "Microsoft monoculture" or any
other monoculture (hmmm...a devil's advocate question: what would happen
if qmail was the only MTA in the known universe?).

there is precedent, it's still relatively open.

Re: AntiVirus!

2000-12-05 Thread Felix von Leitner

Thus spake Stuart Young ([EMAIL PROTECTED]):
   I disagree with the assertion that virus scanners are non-solutions.  On
the mail servers I run, I have installed some simple virus scanning
   software, and it has, up to now, filtered out lots of incoming virii and
   trojans, as well as a few outgoing virii (which alerted me as to who was
   infected, and allowed me to advise the IT folks so they could go clean it
   up).  Its not a perfect solution, but its far better than nothing, and
   results in our location not becoming a source for that kind of garbage.
 Let me get this straight.
 
 Based on the fact that your virus scanner detected a few outgoing virii,
 you assert not only that it has detected all of them.
 I don't see how you got "All" out of "filtered out lots of incoming virii 
 and trojans", which clearly does not say it covers everything. Please stop 
 generalizing.

Stuart, do you know the difference between "incoming" and "outgoing"?
Are you aware of the meaning of "to become"?  It implicates that you
aren't already.

 In Europe, Elementary Schools have more professional IT departments than that.
 IT Departments are there to solve user problems, and to solve 
 company/institution problems. A virus can quite happily be both. I have 
 seen a number of 'network/computer issues' (outside of the office I am in) 
 that have been related to virii causing unpredictable behavior. Ignoring 
 the problem only allows it to fester, and will only make the final cleanup 
 (which will most definitely be the IT Departments problem) much longer, 
 problematic, and far more costly. How much does your company/institution 
 price it's data, and it's down-time?

My company does not have downtimes because of viruses.
What do you mean with "computer issues"?  I don't think I have those in
my company.

People will only notice the system administrator when something is broken.
So, the job of the system administrator is to be invisible.

 And what operating system your network clients run is not always your
 decision to make.

Of course it is.
Otherwise you should leave the company to their doom.
Technical decisions have to be made by the technicians who have to work
with the stuff later.  If that is not the case in your company, it is
doomed to failure and misery and in the end it will be blamed on you
nonetheless.

 A virus scanner isn't the whole solution. But it's a part of a solution
 that is definitely worth investigating. It may not necessarily be part of
 your solution, but your solution isn't necessarily good for anyone else either.

Which part of the reasoning against virus scanners didn't you
understand?  You repeat exactly the same marketing lingo that the others
guys also used.  Is there some secret mind control conspiracy abound
that makes people repeat phrases like "virus scanners are [...] a
solution"?  I don't get it.  Is none of the Windows users open to
rational arguments?

Re: AntiVirus!

2000-12-05 Thread Felix von Leitner

Thus spake Milen Petrinski ([EMAIL PROTECTED]):
  This is the biggest lie of computing: that there is no choice.
  Everyone has hundreds of options, but the American culture apparently
  revolves around taking the wrong choice, blaming it on circumstances and
  whining about the consequences.
 Just an example:

 You are installing a new mail server for a company, that uses Windows on
 their workstations. Than the boss says "What about viruses?" - will you
 reinstall all the machines,s OSes with *ix and teach them use it?

I then tell the boss that his business is doomed unless he wipes Windows
off his machines.

I did this before and I will do this again.

Sometimes the boss then asks me to train users, and as long as he pays
me for it, why shouldn't I do it?

How does doing virus checking twice help? It should be done once when it

 It seems to me that one of the major solutions to this problem would be real
 OS level security on more machines (ie not windows).  The big problem there
 is cost, training, availability of software, politics, user acceptance, etc
 etc ad nauseum.

No the problem is active documents. These can cause problems under any
moderately useful OS. When people get files that act as though they are
read only, it is a good idea to make sure that they really are read only
so that it isn't easy to fool people.

Windoze doesn't have a monopoly on active document formats. Latex/Tex
and Postscript (though unix postscript readers generally don't allow
the dangerous functions to work) both allow for active documents that
can cause problems.

Their idea of running files that are clearly labelled as programs
from web pages and email messages without really making sure the user
understands the risk, is something I do think they have a monopoly on.

Just an example:

You are installing a new mail server for a company, that uses Windows on
their workstations. Than the boss says "What about viruses?" - will you
reinstall all the machines,s OSes with *ix and teach them use it? Teach them
to use all the new softwere? Are you able to do that? I suppose not, so

It's been awhile since I've posted to this list, but I must point out
that this "watch and wait" vigil-style virii detection isn't really
all that useful when you're asleep and wake up the next morning to
your staff executing a script that is wiping the hard drives of every
machine on your network. Hec, wiping out even just one of my bosses
computers is a nightmare...

Agreed, but I would have been remiss had I not augmented our filtering when
news hit.  Its certainly not the best filtering methodology on the market,
but it did stop us from having any problems.  Certainly better than doing
nothing considering how many copies of that thing we filtered.

Let me get this straight.

Based on the fact that your virus scanner detected a few outgoing virii,
you assert not only that it has detected all of them.

I don't see how you got "All" out of "filtered out lots of incoming virii 
and trojans", which clearly does not say it covers everything. Please stop 
generalizing.

And the role of your IT department is to walk around and clean up virus
infections.
What kind of institution are you working in?
snip!
In Europe, Elementary Schools have more professional IT departments than that.

IT Departments are there to solve user problems, and to solve 
company/institution problems. A virus can quite happily be both. I have 
seen a number of 'network/computer issues' (outside of the office I am in) 
that have been related to virii causing unpredictable behavior. Ignoring 
the problem only allows it to fester, and will only make the final cleanup 
(which will most definitely be the IT Departments problem) much longer, 
problematic, and far more costly. How much does your company/institution 
price it's data, and it's down-time?

And what operating system your network clients run is not always your 
decision to make. Add to that the fact that the more complex the 
application and operating system, the more likely bugs are introduced, with 
the consequence that there will always be some sort of exploit for a hell 
of a lot of software, even on Unix/Posix based platforms. A good (fairly 
secure) operating system (which really means the kernel and a few select 
tools) doesn't mean that the applications will necessarily follow suit.

One of my favourite sayings is: "Everyone has the computing platform he
deserves."  And for your statements here, you deserve all the Windows
2000 that you can carry.

Unfortunately you don't always have the choice that you may want, simply 
due to the nature of your business, or due to lack of applications. Many 
people I know wish they had the luxury of having everyone using a 
non-windows platform for clients. I'm quite lucky that we are heading in 
that direction, but we will not be windowless for a while yet.

A virus scanner isn't the whole solution. But it's a part of a solution 
that is definitely worth investigating. It may not necessarily be part of 
your solution, but your solution isn't necessarily good for anyone else either.

I agree, as I state in one of my previous posts, real OS security would
resolve a large portion of this, and Windows just doesn't have it, nor do I
expect it will in the foreseeable future.  Until then, we have to apply
whatever band aids keep us up and running.

User education is also a problem.  Everybody believes that you can

I understand that sentiment, and even agree to an extent, but the kind of
time and money necessary for "proper" training is hard to come by (at least
where I've worked).  When you add to it an ignorant user base and new
software being rolled out almost monthly, it becomes almost impossible to
fully train some people.  I've had some users that, in training sessions,
picked up the concepts and information as fast as we could feed it to them,
and others whose hands you had to hold though the whole process, and they
still didn't really "get it".  You can't just get rid of these people, as
many of them were essential to the various departments for which the work,
and most were exceptionally talented in their particular field.  They just
were not raised with computers.  This will probably only get better though
as the workforce transitions to the children and young adults who have grown
up with them and technology progresses.  So, we do the best with the people
and resources we have.  Virus scanners are just another tool to facilitate
this.

(Hi Felix)

I would say the cost is higher than normally reckoned: you end up
with dumber users, and that's pretty expensive.

I've been thinking of a scheme in which attachments of certain
"dangerous" types get mangled, such that the filenames or types
are intentionally misdeclared.  So the user ends up with a plain
base64 text file, which is meaningless, but which he can trivially
decode to the original.

This places the burden of vigilance back on the user where it
belongs, rather than breeding a generation of click-happy users.

And if he does decode and run it, and it is a virus, you can point a
very accusing finger instead of a palms-up shrug.

Re: AntiVirus!

Like Felix I'm skeptical about the value of general anti-virii programs 
running as gatekeepers on Linux servers.

However, I have found AMaViS (A Mail Virus Scanner; 
http://amavis.org ) very useful for filtering out e-mail viruses, a very 
annoying and prominant subgroup of viruses.

AMaVis works with qmail but requires a separate anti-virus scan 
engine to work in conjunction with it.  It supports a number of such 
scan engines.  For example, I use McAfee's VShield 4.x scan 
engine under a corporate license.

My enterprise also uses PC-based and Novell-server based anti-
virus software but these have the disadvantage of needing to be 
properly configured, and the weakest link in this kind of distributed 
defense would be the handful of PCs or servers that had a 
misconfiguration.

With AMaViS at the pass, there's the ability to passively run e-mail 
virus filters as every single e-mail comes in.

If you decide to use this or a similar approach, you need to make 
sure that a cron job runs to periodically update the ant-virus .dat 
files from your scan engine's website.  Otherwise your database of 
antiviral signatures gets obsolete.

A lot of the most "deadly" attacks could have been stopped dead with simple

A simple example would be to look for extensions that indicate executable

Felix von Leitner [EMAIL PROTECTED] writes:

 Signature based detection can never catch current virii.

Either

s/current/new/

or 

s/catch/reliably catch/

There can be no argument that a signature based virus scanner can
catch SOME viruses.  The question is how reliably.

The two issues are:

1) Virus signatures MUST lag behind viruses.  Therefore there is
always a window in which the virus exists but not the signature.
Signatures only help you if you're not an early victim.

2) The actual virus code may be hidden inside a wide number of
packaging schemes; different mime encodings, compression formats,
encryption formats, etc.  It is impossible for a virus scanner to be
able to read them all.  Thus some known viruses can slip by because
they're inside an unknown packaging scheme.

Therefore, signature based scanners CANNOT be a 100% reliable method
for preventing viruses.

Felix, you seem to be of the opinion that anything less than 100%
effectiveness is worthless?  Or is it just that in your opinion
signature based scanners are TOO FAR beneath that 100%?

IMHO point (1) is more important than (2).  Most of the time, viruses
arrive in standard formats.  Virus spread, however, is very fast
nowadays -- it is increasingly common to get the virus before the
signature, while in the past (given slow methods of propagation such
as floppy disks) viruses spread much more slowly.

And yes, the right solution to viruses is getting rid of the holes
they exploit.  There is no good reason why the functionality a Word
macro virus exploits needs to exist.  However, good luck getting
Microsoft to fix their broken logic!

Plus, they are a security risk in themselves.
And, they normally even cost money.

 Felix, you seem to be of the opinion that anything less than 100%
 effectiveness is worthless?  Or is it just that in your opinion
 signature based scanners are TOO FAR beneath that 100%?

If running a virus scanner would be free (i.e. does not reduce security,
does not eat up CPU time on the email server, does not use memory, does
not cost time and money to maintain) then I would not be against it.

But virus scanners are a marketing vehicle for a whole industry that
did nothing to prevent any virus I have ever seen anyone close to me me
have.

 And yes, the right solution to viruses is getting rid of the holes
 they exploit.  There is no good reason why the functionality a Word
 macro virus exploits needs to exist.  However, good luck getting
 Microsoft to fix their broken logic!

I don't care about Microsoft and what they fix or don't fix.
I don't use their software and document formats.
It's that easy.  Really.

Nothing is free.  All that is possible is that the cost is less than
the benefits.

 But virus scanners are a marketing vehicle for a whole industry that
 did nothing to prevent any virus I have ever seen anyone close to me me
 have.

I used to work for an antivirus company (no longer; figured there was
no future in it, and didn't want to paint myself into a corner).
Obviously given that experience I have found virus scanners to prevent
some viruses, quite a bit in fact.  This was in the days when the PC
boot sector virus was the major type, though (for once, not a type of
virus MS can be blamed for, really -- MSDOS never pretended to be more
than a glorified progam loader anyway).

Whether the cure is worse than the disease; ah, there's the issue.
And a LOT of characters in the AV world are less than savory.

There is no truth in the concept that the AV vendors themselves write
the viruses, though!  There are PLENTY of losers out there to do it
for free.

 I don't care about Microsoft and what they fix or don't fix.
 I don't use their software and document formats.
 It's that easy.  Really.

Personally, neither do I.  However, many of us work in organisations
that do use them, and we can't change that.

Re: AntiVirus!

2000-12-01 Thread Al Lipscomb

 
 2) The actual virus code may be hidden inside a wide number of
 packaging schemes; different mime encodings, compression formats,
 encryption formats, etc.  It is impossible for a virus scanner to be
 able to read them all.  Thus some known viruses can slip by because
 they're inside an unknown packaging scheme.
 
 Therefore, signature based scanners CANNOT be a 100% reliable method
 for preventing viruses.
 

Depends on what you want to put in place. Simple rule: no attachments get to a 
MUA, they are removed and put into a secure file area. If they can be scanned
and found to have no potential to carry code then they are sanity checked and
may be picked up by their owner. If they can or do carry code then they must be 
inspected by hand and then a signature checking virus scanner. 

Sanity checks would include resonable headers and characters that are
printable. 

The down side of this is you get many false hits. The good side is that while
the signature based systems are waiting for updates you have a pile of
.vbs or .exe files waiting to be looked at. 

Solutions include both commercial and roll your own. 

 
No solution is 100% but prescribing a solution that is only signature based
is not enough. Having to shut down email to a 3,000 user organization 
due to the latest "love bug" attack will not win you friends.

Of course getting it right got me (and the rest of the team) a nice
polo shirt from Symantec.

 this would be acceptable. Are the updates automatic, or do they

How should the updates be done automatic? I use a cron-job starting wget
each night and restart AvpDaemon after successful download. I would not
use win-like programs where I don't have the source and which would do
something automatic...

Or do you mean the license-file itself? Don't have experience with that
cause the license-files of the servers I administrate run until Sep
2001. And then I will contact AVP and buy some new licenses.

 Well, Martin, some more details on this issue could be useful? (what are

If you start scanning a file|directory without a valid
registration-key-file you are prompted "Cancel scan process" and have to
type "No" to continue. If you have a valid key-file the scan is done
without this question.

Well, several ppl reported problems with AVP/Linux and AvpDaemon to the
AMaViS-user mailinglist. We discovered problems when
/lib/libnss_compat.so.1 is missing (it comes with nssv1.rpm on SuSE
Linux, which should be installed to execute glibc 2.0 programs in glibc
2.1 environments). And I was in contact with the developer regarding
this problem.

qmail-scanner + which antivirus ?

2000-09-24 Thread Olivier M.

Hello,

I'm currently trying to install qmail-scanner (antivirus)
on a server: basic installation seems to work well. Now I
need a virus scanner : on the homepage http://qmail-scanner.sourceforge.net/
the following are listed:

 * Trend's Virus scanner
 * Sophos's "sweep" virus scanner
 * H+BEDV's antivir scanner
 * AVP AVPLinux scanner
 * MacAfee's (NAI's) virus scanner
 * F-Secure Anti-Virus scanner

Just tried to use it with AVP and sweep : both returns a
   X-Qmail-Scanner-0.90: corrupt scanner/resource problems - exit status 256
in the logfile... 

If you are using qmail-scanner, could you please tell me which
program is working well, and if is free ? Thanks in advance,

Olivier
