Security Considerations
Table of Contents
It must first be pointed out that by using PostCast Server on your computer,
nothing will be deleted from it and no data jeopardized by any person
who has connected to the server without authorization. The worst that
could happen is that this person delivers a pile of messages to the server
that it will then try to send. The damage that might thus be inflicted
comes down to using the computer resources and congesting
the Internet connection. All this can be avoided by setting the "Security" options in the "Settings" window of
the server. You can enter trusted IP addresses from which the program
will accept connections, as well as block certain IP addresses.
LAN or Local Access
If the program settings are defined to accept connections only from
the computer where the program has been installed, that is, if "localhost"
or 127.0.0.1 is entered in the "Host Name" settings, then the program
cannot accept connections from the Internet or LAN. In this case, you
do not need to worry about any unauthorized person connecting to the server.
If the program accepts connections
from LAN, then it cannot be accessed from the Internet. If you want
to limit access to certain computers from LAN, use the "Security" option
from the "Settings" window.
Internet Access
Only if you use your Internet IP address
as a Host Name, someone can take advantage of the server from the Internet.
Your computer acts as an 'Open Relay' if you allow unrestricted access
to the server from
the Internet. For more information about this problem, see Blocking
Open Relays. |
