An intrusion detection systems
(IDS) is a device or software applications to detect the presence of
an intruder attempting to breach a network or systems. Tremendous
growth and usage of internet raises concerns about protection and
communication of digital information in a secure manner. Intrusion is
a major problem for industry, commerce and governments worldwide. So
detection systems that can provide a fast alert to intrusion have an
increasingly persuasive role to play. IDS monitors a network or
systems for malicious activity or policy violations, and alerts the
network administrator or collects centrally using a security
information and event management (SIEM) system. SIEM combines outputs
from multiple sources, and uses alarm filtering techniques to
distinguish malicious activity from false alarms.

There is a wide spectrum of
IDS, varying from antivirus software to hierarchical systems that
monitor the traffic of an entire backbone network. Classification is
based on analyzed activity approach or detection approach. Analyze
activity approach holds network intrusion detection systems (NIDS)
and host-based intrusion detection systems (HIDS). NIDS identifies
intrusions by examining network traffic and monitors multiple hosts,
connecting to a hub or network switch configured for port mirroring.
While HIDS entails an agent on a host which identifies intrusions by
analyzing system calls, application logs and file-system
modifications. On the other hand, detection approach comprise of
signature based detection which uses specifically known patterns to
detect malicious code and anomaly detection which are designed to
detect abnormal behavior in the system.
Intrusion Prevention Systems
(IPS) extended IDS solutions by adding the ability to block threats
in addition to detecting them. Intrusion detection and prevention
systems (IDPS) are primarily focused on identifying possible
incidents, logging information, attempting to stop, and reporting to
security administrators. The threat of authorized users misusing
privileges and proliferation of heterogeneous computer networks are
major implications for intrusion detection problem.
Increasing adoption of new
technology in both commercial and industrial sector is anticipated to
drive the market growth. Development in semiconductor technology such
as LED and photo diode, biometrics technology provides finger print,
palm veins, face recognition, iris recognition, DNA and retina
authentication. Integration of detection system with such
authentication system result into fulfillment of high security demand
of certain industries, which contributes to market growth in near
future.
Global intrusion detection
system market is expected to grow rapidly during the forecast period.
Increasing cybercrime and unauthorized practices are expected to be
key factors that drive the global intrusion detection system market.
The growing acceptance of cutting-edge intrusion detection
technologies in the IT companies, increasing security threats to
enterprise network, increasing government pressure on compliance of
policy and regulations are also driving the growth of intrusion
detection system market.
There are several challenges
to the intrusion detection system growth such as lack of awareness.
However, these issues can be tackled by conducting several awareness
campaigns. High product and installation cost may also hamper the
market demand.
Global intrusion detection
system market is segmented on the basis of type, services and
deployment model. On the basis of type, the global intrusion
detection system market can be segmented into host based intrusion
detection system (HIDS), network based intrusion detection system
(NIDS), signature based detection and anomaly detection. On the basis
of service, the global intrusion detection system market can be
segmented into design and integration services, managed services,
training & education and consultancy services. On the basis of
deployment model, the global intrusion detection system market can be
segmented into on-premises deployment and cloud deployment. Moreover,
on the basis of geography the global market is classified into North
America, Europe, Middle East and Africa, Asia Pacific and South
America.
