Wireless Intrusion Detection System

As this is an information age, manual procedures and information is digitized. This is the reason why computer security is becoming a challenging task. Previously, firewall was considered as the core component for eliminating network related threats. Today, things have changed, now advanced security appliances and technologies are required such as IDS. Intrusion detection system has also evolved in to a separate term known as Wireless intrusion detection system. However, the mechanism is the same as per traditional IDS except sensing capability of detecting threats coming from a wireless network. WIDS can be defined as the process of examining the events that may have an abnormal behavior in a network or a computer system that can be identified as intrusions (Douligeris,). The components of a typical WIDS consist of agent, Sensor, Server, Console & Management, Reporting tools.  WIDS typical secure wireless network infrastructure by live sensing of data traffic coming from several data streams. Alert mechanism is efficient and reports any weakness robustly, that may allow the network engineers to react and isolate the threat. Moreover, threats from both i.e. inbound and outbound network are identified and traced. On the other hand, there are certain weaknesses that are associated with WIDS. For instance (Marina L. Gavrilova et al., ) Wired equivalent privacy (WEP) is fragile resulting in an inclusion of a threat between an ongoing data transmission. Moreover, hackers may also initiate a Denial of Service (DoS) attack by flooding the WAP via association requests that may result in a reboot.
