Hello, list.

These days, we  have lots of problems about virus and spam.
So I would like to setup viruswall.
Is there any document or site related with viruswall?
Viruswall is similar to firewall?

Thanks in advance.

RE: Security+ Advice

"Then shoot for the Cissp cert" 

Maybe it's just your choice of words, but that just makes it sound easy. Are
you suggesting that a little bit of study, some reading of an exam crap and
a little IT savvy ness is enough to obtain a CISSP? 

What I'm trying to find is how hard is it REALLY to get a CISSP?

Security+ by sybex. If you have a goog handle on security. Just use the

Re: Ethics Question

Mike,  it shouldn't really be a problem for you
to alert Company Y about this. (However, it is now).

1. (Why it shouldn't be a problem)
You knew of this vulnerability in advance. You aquired that
knowledge as part of your job, and noone can hold you liable for
This means you could easily have told Company Y: "have you checked
with Company X whether this thing has been fixed?", based on your old
knowledge. But you can _not_ tell them that you know it still hasn't been

2. (Why it is a problem _now_)
You have no right to know any more. The fact that you _know_
it still hasn't been fixed shows that you have poked your nose
into where it doesn't belong. And, as someone pointed out,
it is now even on record for the entire Internet to see.
Thus, you have lost your chance to alert anyone.

So, next time, don't tell the public what you did, rather go 
to the concerned parties directly.

Anders :)

benefits of IDS (was: Network IDS)

Hello Simon,
nice article, I agree that false positives are big problem of IDS. But there is one more point of wiew you
did'n mentioned (and imho everyone forgets say this when criticising IDS): Active responses. It's good
to be able to reset susppicious connection, block somebody doing bad things on firewall etc. I think thist
(and automatic correlation) could be - and allready is - the future way of IDS.

RE: Password audit dictionary

For those interested in the 22,000,000+ dictionary list, I finally found
it on my hard drives.

# This is from
# 24,083,464 bytes compressed. 245,474,830 bytes un-compressed.
# MD5 of the ZIP file: 014b50d1fcca6503b49f134f62290f8a
# wc output - 22349626 23966196 245474830 22million-words.lst

(now if someone can explain why I PGP'd the uncompressed file it was
 about 1,000,000 bytes smaller than the ZIP?)

As it was written on Aug 11, thus Birl spake unto Technoguru:

Spam question


 I'm reading some sources of spam I've got and I have a question that 
has crossed my mind... Is it possible to malform e-mail's header?

What I have in mind is that some of the headers come with different 
header composition in which up to two *Received:* records are from 
registered range... And also some of these e-mails have *Return-Path:* 
inserted on the bottom of the header, following *Received: from [] by (MAILSERVER NAME vX) with 
PROTOCOL, DATE*... While the original Return-path: with an e-mail 
address, as it supposed to, is one of the top ones...

 I have a theory about this... Could there be a program that connects 
directly to the end-user SMTP server by telnet and makes sends to a 
localhost? I know that would be a lot of traffic and time spent on this, 
but isn't this another possibility? I remember when I was playing with 
SMTP server at home, I was capable of sending any kind of e-mail to 
anybody <at> localhost... So then I've tried it on several "real" SMTP 
servers where I knew my friends had an account and it worked as well... 
Which means if I know the user and the end server, I'm able to send 
pretty much anything and by forming the commands well, it is possible to 
try to malform the header so one of the records might trick somebody 
into believing, that it is one of the SMTP relay hops.

Thanks for your input...

Re: PIX book recommendation

You can find doc about PIX in or you can buy "Cisco Secure
PIX Firewalls" book (but I think online doc is quite good). Additional
