ips network jobs meaning

Cisco intrusion detection systems (IDS) and intrusion prevention systems (IPS) are some of many systems used
as part of a defense-in-depth approach to protecting the network against malicious traffic.
IPS Versus IDSWhat Sensors Do
A sensor is a device that looks at traffic on the network and then makes a decision based on a set of rules toindicate whether that traffic is okay or whether it is malicious in some way.Difference between IPS and IDS
You can place a sensor in the network to analyze network traffic in one of two ways. The first option is toput a sensor inline with the traffic, which just means that any traffic going through your network is forcedto go in one physical or logical port on the sensor. At the sensor, the traffic is analyzed. That is the
concept behind intrusion prevention systems (IPS).IDS is detecting the attack (hence the term intrusion detection system) but is not preventing the attack.
