COMPARATIVE ANALYSIS OF NETWORK SECURITY ISSUES

Without the need of an infrastructure, low-cost, auto-managed, flexible and low power consumer, wireless network is becoming emerging technology. It shows great binder for present as well as future hi-tech applications. Increasing reliance on wireless networks also brings great challenges to the security measures and other correlated issues. Although the newly introduced corrected security standard, IEEE 802.11i, offers extensive security for the wireless environment but it is still premature and does not provide effective measures to protect the wireless networks from confidentiality and integrity threats. The main issues for deployment of wireless networks are security attacks, vulnerabilities, battery power and improper security models. This work provides a study on these problems especially in ad-hoc wireless networks.
