this is my assignment (project) due in a couple hours:

Create a covert storage channel in which the sender creates a flag file
to indicate that the next bit of a message is ready. The receiver reads
the bit and then deletes the flag file. After the flag file is gone the
sender can send another bit of a message. The value (1 or 0) of the bit
sent is indicated by the presence or absence of a bit file, created and
deleted by the sender. The bit file is different from the flag file.
Neither the flag file nor the bit file can have anything written in them;
their presence or absence is all that matters.

Measure the throughput of your sender/receiver system when sending the
contents of a file. (The message transmitted probably should be several
kilobytes long.)

Then modify your programs to send and receive whole bytes at once
indicated by the presence of a subset of eight different files in place
of the bit file. Choose one particular byte to indicate "end of message."
Measure the throughput of this system.

Remember that no information is stored in any of these files.
Information is passed only through the existence or absence of files.


Turn in the following documents stapled together.

1. A listing of both sets of your send and receive programs.

2. A description of how you measured the throughput of the two systems.

3. The measurements of throughput for each system.

4. Suppose you were designing a file system and an operating system
which would resist covert storage channel attacks like the one you
just created. Tell what changes you would make in the file system
and/or operating system to sharply reduce the throughput of a covert
storage channel. How would your modification(s) affect legitimate
file activity?

I cannot get this to work right at all.

Does anyone have suggestions? I learned VB extensively 2-3 years ago.. but since then.. I have lost most of it and I forget how to do many basic things.

IF YOU DON'T KNOW... DON'T POST. I am not in the mood.. I need serious help here.

This is not even a programming class :blow_top:

Network Securities :D

They don't teach this sort of thing in most regional schools (so our teacher told us). Its not "normal" to teach covert channels and how to steal from programs unnoticed lol.

yes... we are learning a bit of hacking..etc..

BUT... I need help :help: :help: :help:

This crap is HARD to do... at least this project is.

Other things we have learned:
1.) manual decryption of encrypted messages... I sucked at this BAD.
2.) Different security leaks...etc..etc.
3.) now this project.... and I suck again lol. Not too many people know whats going on.

I have been in this class for only 4 weeks (this is the 4th week).

and we had to go through a chapter of ethics before we continued on with the rest LOL

thanks!

Post this same thing on shacknews.com on the evening reading thread tonight. I garuntee you'll get the VB nerds out answering your questions.

There's usually some complex math posts every night that get answered. I always found it strange the people that post there know that stuff.

Who the hell does network programming with VB? Winsock is okay and all but...bleh.

Good luck with your problem though.

Its not off of a network. .... basically on the same computer. He said we can use any language we know to accomplish the task... but alas.. I only know VB as of right now (strict programming language speaking)

and VB.net is pretty cool for network programming.

BTW Nick....... Guess what our next project is.

ITs a long project that will take about 2 weeks. We 1st have to
get Vmware and use it on our linux machines..... we have to run 2 Windows XP windows (..essentially they run as 2 OTHER seperate machines on your linux desktop).

We have to have 1 be the admin... and the other as the "clueless person"

Then we are going to work with some backdoor stuff IE BOK2, and.. there is another one but I forget it right now..... then we need to get into the other computer 3 different times: 1.) when BOK2 is installed on the machine.
2.) when we have to slip BOK2 into the background and take control
3.) When we have to slip BOK2 into the background and take control with virus protection software running (not necessarily a firewall running).
... THEN we have to try to slip viruses in. We have to pick a virus, AND write a report on the virus.

We are also (in the same project) working with buffer overflows...etc. But that is really complex to go into all that we have to do.

At the end... we have to give a 5 min presentation on the virus...etc..etc.. AND a 3-5 page report on all of our steps... our programs made for the buffer overflows... and much more.

alll that in 2 weeks.... and its only a 3 credit course... junior level. THAT SUCKS lol. ESPECIALLY WHEN I DON'T HAVE THE 1st ONE DONE YET!!!!!!!!!!!!!! ARRRGH

What do you think of that? lol

you work at symantec, eh? Thats SWEET!
What do you do?

BTW.. I will try that site. I am going to give it till sat night. If I cannot figure it out by then... I am posting on that site.
Thanks for the information!
My teacher was nice enough to give me a few more days (with a little decrease in the project score).

I am tired as heck right now .... I went to bed at 3am this morning and got up at 6:30 to try to finish it. I worked on it the WHOLE DAY till my class at 4:30 :(
