Hi, Unfortunately I don't know of any USB devices of the kind you mentioned, in fact the USB suggestion was just something the occoured to me while reading your question. I think you need to outline more regarding the type of attacks you are trying to protect yourself from.

(2)The user should not be able to delete the file which we wanted to achieve with logging to a CD-ROM. Your idea with the USB memory card sounds interesting. Do you know any lockable (and maybe even encrypting) USB memory cards which can be used on linux? I could only find some that run on a Windows Box...

You can write to it the same way you would write to an HD. If you want to make the file tamper proof either act through obscurity or (better yet) use some encrypted file system. The prefered device would be a USB memory card that can be locked for safe keeping. You can also digitally sign the entries assuming the machine's security measures don't make the key pair too easy to retrieve.

As for the application, it is very important that the log cannot be modified by anyone (!) after it has been written. Therefore everything that involves either a harddrive or a floppy is out of question - I wonder if anyone has an idea how to log to a CDRW? Any help is appreciated.
