The document outlines security strategies for wireless transmissions, access points, and networks. It also describes the phases of IEEE 802.11i including discovery, authentication, key management, and protected data transfer.
An open, unencrypted wireless network can 'sniff' or capture and record the traffic, gain unauthorized access to internal network resources as well as to the internet, and then use the information and resources to perform disruptive or illegal acts.Many laptop computers have wireless cards pre-installed. The ability to enter a network while mobile has great benefits. However, wireless networking is prone to some security. Wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks.The risks to users of wireless technology have increased as the service has become more popular.As a result, it is very important that enterprises define effective wireless security policies that guard against unauthorized access to important resources.
A presentation which on Wireless Network Security. It contains Introduction to wireless networking, security threats and risks, best practices on using wireless networks.

Throughput Analysis of IEEE WLAN "802.11 ac" Under WEP, WPA, and WPA2 Securit...CSCJournals
WLAN (Wireless Local Area Networks) are gaining their grounds, and widely deployed in organizations, college campuses, public places, and residential areas. This growing popularity of WLAN makes these networks more vulnerable towards attacks and data thefts. Attacker attempts unauthorized access to the network for accessing the sensitive data of the users. Thus, it's necessary to address all the security challenges and its countermeasures using various encryption algorithms to prevent the attacks. However, with the use of security protocols the performance of the WLAN network can be varied. Thus this paper addresses the impact of various security protocols on the WLAN network, keeping throughput as the benchmark for network performance.
IEEE 802.11 ac is the latest wireless standard that operates in 5 Ghz frequency band with higher data rate, compare to its previous standards. This research has also chosen IEEE 802.11 ac standard for investigating the impact of security protocols including WEP (Wired Equivalent Privacy), WPA (WiFi Protected Access), and WPA2 (WiFi Protected Access 2) on throughput of WLAN IEEE 802.11 ac in Windows environment using TCP and UDP traffic for both IP versions (IPv4 & IPv6). The research was launched in a real test-bed setup, with a Client/Server network structure. The results from the experiment showed that the performance of data throughput in the open system were higher comparable to secured systems. However, the results demonstrated that the performance of throughput have different behavior to different security protocols under TCP/UDP traffic with IPV4 & IPV6. A detailed comparison of results in all scenarios is explained in the paper.
Wireless Security Best Practices for Remote Monitoring Applicationscmstiernberg
Wireless network security continues to be an area of intense research and development, particularly in applications where wireless sensors are extending the reach of traditional monitoring and control systems. While the IT sector has embraced the IEEE 802.11i standard for corporate networks, engineers have many more options available to them for their industrial network designs. This presentation will provide an overview of IEEE 802.11i, IEEE 802.15.4, ZigBee, and other security protocols as they relate to measurement and automation applications. In addition, network design and commissioning best practices will provide attendees with a set of recommendations for guarding against the most common security attacks.
Evaluation of enhanced security solutions inIJNSA Journal
Traditionally, 802.11-based networks that relied on wired equivalent protocol (WEP) were especially
vulnerable to packet sniffing. Today, wireless networks are more prolific, and the monitoring devices used
to find them are mobile and easy to access. Securing wireless networks can be difficult because these
networks consist of radio transmitters and receivers, and anybody can listen, capture data and attempt to
compromise it. In recent years, a range of technologies and mechanisms have helped makes networking
more secure. This paper holistically evaluated various enhanced protocols proposed to solve WEP related
authentication, confidentiality and integrity problems. It discovered that strength of each solution depends
on how well the encryption, authentication and integrity techniques work. The work suggested using a
Defence-in-Depth Strategy and integration of biometric solution in 802.11i. Comprehensive in-depth
comparative analysis of each of the security mechanisms is driven by review of related work in WLAN
security solutions.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
