Explanation:
Sniffer functionality means the ability to capture and analyze the content of data packets as they are transmitted
across the network.
IDS and IPS systems perform their functions by capturing and analyzing the content of data packets.
An intrusion detection system (IDS) is a device or software application that monitors network or system
activities for malicious activities or policy violations and produces reports to a management station. IDS come in
a variety of “flavors” and approach the goal of detecting suspicious traffic in different ways. There are network
based (NIDS) and host based (HIDS) intrusion detection systems. Some systems may attempt to stop an
intrusion attempt but this is neither required nor expected of a monitoring system. Intrusion detection and
prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about
them, and reporting attempts. In addition, organizations use IDPSes for other purposes, such as identifying
problems with security policies, documenting existing threats and deterring individuals from violating security
policies. IDPSes have become a necessary addition to the security infrastructure of nearly every organization.
IDPSes typically record information related to observed events, notify security administrators of important
observed events and produce reports. Many IDPSes can also respond to a detected threat by attempting to
prevent it from succeeding. They use several response techniques, which involve the IDPS stopping the attack
itself, changing the security environment (e.g. reconfiguring a firewall) or changing the attack’s content.
