Hi,
Usually the phone numbers of a company are in the same range, the same way usually as they IP addressed that they get assigned from their ISP.
An attacker might look up your company's phonenumber and try to dial the numbers below and above it.
Ie. your company's phonenumber is 555-2345. An attacker might try all the numbers in the 555-234x range.
You could add an extra layer of security by changing by connecting the fax to a phoneline with a phonenumber that is not 'near' your company's phonenumber(s).
So if your company's phonenumber is 555-2345, the faxline would have a totally diffrent number like 555-8896.
Met vriendelijke groet,

Ensure the modem is not configured to accept incoming calls. Also don't
allow bridging or connection sharing on this pc. I don't know if its
possible to restrict access to ISPs or not.

Subject: fax software in the domain
Hi,
Im my domain we have w2k servers and the workstations
we use xp pro.
On the station of one employee he must use also a fax
with a modem connected
to the telefhone line.
I think that this is a security problem.
I cant remove the fax from his pc .my question is what
are the steps to
protect this pc from being a security problem to all
the network ?
thanks !!
