Re: {bb} Modem Not Answering?

[Daniel O Winkless <wink@usgs.gov>]

Sorry Paul,

        I did not miss the point.  In my situation, inbound is impossible, so no monitoring is needed.  The writers asking for how to monitor incoming modems (you too) need only the outbound capability and if that could be available at all times w/o any inbound, you would all be happier.

        I am suggesting that others attempt to adopt a strategy similar to mine.  Modems open vulnerabilities IF they can be called from the public.  Shane's original query would not be needed at all if the modems could not be called.  That the modems are on publicly callable lines means they are vulnerable, the company needs a policy, and they need monitoring to verify compliance with the policy.

        Wouldn't eliminating the vulnerability be even better, especially if it's possible to continue to provide the support services?  I have zero need to monitor my modem.  It's the inherent two-way nature of modems that cause your concerns.

        Look at how many people are involved at you company for every modem use.  Every one has other tasks to perform, except they can't because inbound modems are a problem and need the coordination described to limit or eliminate the problem.  Eliminate the ability to call the modem and you don't have to monitor its availability.

        I don't have suggestions for how to write such a script to work with BB.  I have a suggestion for how to eliminate the need for such a script.

        From my security minded standpoint, I'm in a better situation than you are.  Get you NOC analysts to assign outbound only numbers to you modems and stop worrying, stay bored.  Bored is good.  Wish I could be bored again.

                Dan

I think you're missing the point.  It's not outbound
that 
needs monitoring, it's the lack of inbound.  We have the 
same issue, and D'OH! I had never thought to use BB.
We only have the modems turned on when a support 
call from a vendor is expected.  Then a NOC Analyst 
brings one of our dial up interfaces online, and turns 
it off when the engineer is finished.  Something new 
to work on now...I knew I wass getting bored.

Hi All,
        I understand the desire NOT to have modems
available for dial
in. 
I don't want that either.  My BB server has such a modem so that qpage
can 
dial out to send pages.
        Our PBX allows us to define phone numbers that
cannot be dialed

from outside.  Our PBX number is 505-XXX-7900.  My modem's number
is 
505-XXX-5938, a number that might get to someone, but it won't be my 
office.  This means I can leave the modem on all the time and war
dialing 
will not find it.  Well, within the PBX, someone can call it, but
if
they 
are in my PBX, they are in my LAN, so no need,
        Anyone who needs only dial-out capability should
see if their 
phone systems can do this.  Then you don't have to monitor it.
                    
   Dan

Re: {bb} Modem Not Answering?






Did anyone ever do this?  I have a similar need and was hoping to
leverage the work.
