Controlling COM ports.
It is necessary to control COM ports in order to prevent the
unauthorized use of modems. The firewall is a device
used to protect Internet connections. This leaves the
user with the option of using his or her own modem for unrestricted use
of the Internet. This reduces the security provided by a firewall. Many
computers connect the pointing device (mouse) to one of the COM ports. If the COM port is disabled, it must be possible to check
whether the connected device is a modem or pointing
device. If it is pointing device, the COM port should
not be disabled. COM port control exists at several
levels. We know that many programs are written direct
to hardware, so they do no use system calls to obtain access. Many
access control programs are unable to prevent this. You should therefore find
out whether the COM ports can be checked to see which communication software
is in use.
