Generally speaking, a firewall is a means of controlling, through
hardware or software, what kinds of traffic are allowed into your
machine or network through which specific ports. It includes the
capability to block that access. An IDS is a means of observing
what kinds of traffic are moving into and through your system that
may be of interest for security reasons.
