hackers are not interested in your wvdial.conf file - they are not interested in anything they do not own.

as far as crackers goes, if they get root on your machine, there's nothing more you can do, so your best attempt is to secure your machine.

if anyone can read your wvdial.conf file just by doing a cat, then 1) that person isn't a cracker, 2) you've got to understand file permissions.

make wvdial.conf readable only by root, make wvdial run only as root (in any case, only root should have access to your /dev/ttyS0

alternately, create a separate modem user that can do these things, and get it to run as that user (setuid).

it could very well be possible that someone from the web could have a look at the file.

how? explain how you think this might happen.
