There is a 'security through obscurity' factor. If few people know of the
details of your home-grown apps then few can mount a specific attack on
them. Mass scanners will probably be able to detect the passage through the
firewall but if your home-grown app resists the standard follow-on probes
then they are reasonably secure.

Subject: vulnerability of non-standard ports
We may need to open a port or two for "home-grown" applications, e.g.
tcp-1234, tcp-2345, on a Checkpoint Firewall-1 v4.0. Would it cause any
security concerns? Any comments/suggestions are greatly appreciated.
Thanks,
Ivan.
