Intrusion Detection refers to pro-active monitoring of a
network for unauthorized access as defined by the security
policy. It uses known patterns, of attacks, looks at
signatures, and can check against a known database of sites.
IDS features are built into many of the new Integrated
Security Appliances by vendors like Cisco, Juniper, etc.
Newer firewall vendors like Palo Alto networks are
integrating many features into the firewalls that overlap
with an IDS. Snort is a free IDS that has been available
for years. It is great- if you have some in house IT expertise.
IDS is often listed with IPS- Intrusion Prevention Systems.

Hi,
Intrusion Detection is defined as whenever an Attack is
happening the work of IDS is just to Detect an Attack and
cannot stop the Attack in terms of Firewall an attack is
detected by IDS and keeps a copy of that packet in state
table and allows to enter into Network,So to overcome this
attack one should make use of IPS Intrusion Prevention
System which not only detects an attack but also stops an
Attack.
