I'd start off with DEC SEAL if you intend to put this system on the
general Internet.  Knowing a little more about what your security
concerns are would be helpful.

This is not terrifically responsive.  The original assertion was

>different level of software sharing between the users.

(Sorry to not be able to retain original attribution.  It's not my
 statement, however.)


Yes, Cohen's papers describe what is _theoretically_ possible and
impossible about the spread of viruses.  The question being debated
is "Why doesn't a UNIX virus exist in the wild?"  A whole bunch of
straw men have been proposed and subsequently knocked over: file permissions,
address space separation between processes, more knowledgable users,
basic OS design that includes some small amount of security, lack of user
patchable interrupts, and greater morality/ethicality of UNIX programmers.
It's _theoretically_ possible to write a UNIX virus based on the info
contained in his papers, or info from a multitude of other books/papers. 

Sinced it is widely asserted/believed that publishing PC virus source code
is really conducive to more PC viruses (Ralf Burger's Vienna Virus source
is said to have led to major Vienna Virus infestations and variations,
the "Little Black Book Of Computer Viruses" was widely denigrated for
the same reasons), and everything short of compilable source code for
viruses has been published, there must be some reason why UNIX viruses
are not more widespread.

So, I ask again: are there papers/books/other references to studies of
the spread of viruses?  I would be interested in them because of the
dissonance explained above.  It also seems to me that Professional
Anti-Virus folks would be interested in such, since it seems that
vectors of infection would be a logical place to start preventing spread.

Yours,

No, it is not. The most that can be said is that crypt(1) uses an
"Enigma-like" cypher. Actually, it implements a one-rotor, 256-letter
no-reflector version of Enigma. The Unix crypt(1) certainly CANNOT be
used to read and write messages, understandable by the -real- Enigma.
(The real Enigma had three or four 26-letter rotors and a reflector.)
BTW, the program "enigma.c" than can be found with archie does not
create Enigma-compatible messages either. It is an "improved" version
of the Enigma cypher. I doubt that the improvements have made it more
secure, but they for sure have made it incompatible...

No I will not build new ones or let them free. I got 4 children at home

John,

Since your initials are the same as mine, I had to reply: cert.org has
a good faq on securing anonymous ftp, and wuarchive.wustl.edu offers a
hacked ftpd that includes access control, logging, and some other
goodies.  Undoubtedly there are others, but those are the ones I'm
familiar with and know to be worthwhile.

sun has unbundled crypt(1) and des(1). anyway, forget crypt(1). it's

code (i use the des(1) found within the kit-2.0.14 package).

as for des(1) being silly to use, the succeptibility of des to brute
force attack is dwarfed by the key management problem on networked
machines. if you want more security than des(1) provides, forward- and
backward-encrypt multiple times using different keys. see the sci.crypt

You're better off using des to encrypt your files. The crypt command
is very insecure. The Crypt Breakers Workbench (cbw) easily decrypts
the thing in a few minutes. Use des.

Now, Remember that the majority of sysadmins are part-timers who have better
things to do in their company than tighten up the security holes that the
vendors leave in the systems they sell. In most small companies I have seen
where there are just a few Unix, VMS, OS/2, DOS, Mac or-whatever-boxes the
least computer-illiterate person is usually the person who is expected to
spend a couple of hours a day looking after the systems. It's unfair saying
that this sysadmin shouldn't be a sysadmin just because the vendors can't
be bothered making the systems more secure. Tell me the following: when I
install my shining new Sun desktop server option, is there a '.' in root's
path? Is there any access control on exported file systems? Is there a '+'
in /etc/hosts.equiv? The default security in a new installation should be
high, it then would be up to the sysadmin to open up his system to suit his
needs, instead of running the risk of having the system full of holes because
he hasn't known of them. If the system then was full of large security holes
I would agree with your statement, now you're shooting the pianist because
the piano-vendor sold the bar-owner a crap piano.

Actually, I think they should get rid of all this password and
permissions junk. That way the sysadmins will have to write their own
and then they will really understand what security means. Perhaps we
should even persuade the vendors not to sell operating systems. After
all how many sysadmins really understand kernel calls now., or how a

What do you want to SEE actually?? A virus is a program as any other.
Most of the existing viruses do not do anything noticeable. Indeed,
some viruses have interesting video and sound effects. If -that- is
what you want to -see-, then you can get a set of programs that
demonstrate the effects of different viruses. It is available for
anonymous ftp from our site:

ftp.informatik.uni-hamburg.de:/pub/virus/progs/virsim1.zip

Or do you mean that you want to observe the process of the virus
infecting files and disks? Again, no need to use a real virus, there
is an excellent program that demonstrates how a virus infection
spreads in a simulated computer environment. In fact, you will "see"
much more than with a real infection, because the program has very
good logging facilities. It is also available for anonymous ftp:

ftp.informatik.uni-hamburg.de:/pub/virus/progs/virlab15.zip

I have yet to be convinced that there are cases when real viral code
has to be provided to non-experienced users...
