Investigation Of Security Issues Of Wimax Networks

Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

Wireless attacks have becoming a more common security issue when it comes to networks. Attacks can get a lot of information that is being sent across a network and use to commit crimes in other networks. Every wireless network is vulnerable to attacks and it is the important that all the necessary security measures are taken so as to prevent the mess these attacks can cause. These attacks are normally carried out to target information that is being shared through the networks. It is therefore very important to know of such attacks so you will be able to identify the attack when it happens.

Guidelines: It’s always best to introduce a paper to the reader. It sets the tone and provides an overview of what will be covered and what the goals are.

Wi-Fi Protected Access 2, the follow on security method to WPA for wireless networks that provides stronger data protection and network access control. It provides enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. Based on the IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.

The concepts of wireless network security consist of commitment of cyber security and maintaining security based on the latest development and exploits against the network K.W. Ross, J. K. (2012). Wireless Network Security is based on the principles of cryptography, message integrity, authentication, securing e-mails, securing TCP connections: SSL, securing Network layer: IPsec, securing wirelsess: LANs, securing the operational security structure, such as the firewalls and the IDS K.W. Ross, J. K. (2012). This security

The message of its own is send by the attacker on the other end. This is done by avoiding to be noticed by the network. there are solutions provided to these type of problems. The solutions have prevented the attacks to a greater extent and have helped in maintaining the efficiency of the networks [6].

Wireless connectivity is critical to most homes and corporations as the world advances in technology. The technology has grown to a capacity that allows for extreme growth in wireless infrastructure as well as a trend of bringing your own technology device. Many corporations experience a high volume of critically important information being transferred over it wireless network so security is essential. There are many differences between a home and corporate wireless installation and each has its differences in securing.

In an effort to improve security, the Public Safety Wireless Networks (PSWN) program in coordination with the Department of Justice took action to create the Public Safety Communications Security Awareness Guide and focus on solutions to security issues. Therefore, this paper will provide a summary of wireless communications issues and address issues as various agencies cooperate, coordinate, and use interoperable digital technologies to meet public safety requirements. I aim first to discuss communications system security, identify vulnerabilities and address how critical physical, network, communications, and administrative security components operate to protect against intrusions. The final section will include PSWN program, federal, state, and local agencies proposed solutions to improve security

Data link layer controls can be implemented to ensure the security of the transmissions. By using MAC address filtering the stations are identified by not only the MAC address but are cross-referenced with the logical access or physical port. Firewalls should be between layers, ensuring physical isolation from one another. Wireless application must be monitored consistently and carefully for unauthorized access. In order to secure the wireless network, the use of the built-in encryption, authentication, and MAC filtering must be implemented with strong passwords.

In the modern day, wireless technology is buzzing and becoming more and more popular and widely used as each day passes by. Many big corporations like Apple and Microsoft use wireless storage, aka the “cloud,” to provide their users with convenience. Unfortunately, with the continuous advancement of wireless technology, securing sensitive information becomes a complicated hassle. Wireless security is extremely important because many people store sensitive data such as bank account and credit card numbers wirelessly. Not to mention, many people also perform tasks such as banking wirelessly. Wireless security is a major risk to everyone who owns wireless devices, not just big companies. Having strong and effective wireless security is important, so it must be set up properly in order to protect personal information and prevent hardware damage.

Issue Overview Wireless devices, like all technological devices that provide external type access to networks, have special security challenges. Mobile devices and wireless networks rely on a rather broad spectrum of technologies. If one relies on industry standard protocols like TCP/IP, HTTP, SMTP and TAP there are numerous options for enhanced network security. Attacks or vulnerabilities are often based on the operating system of the device or platform being used. Information can "leak" to other networks, Malware can compromise the network, move across platforms, and of course, in some cases, individuals can try to hack in and compromise data (Becher, et.al., 2011).

Some users try and eventually get used the practice that is protecting their endpoint devices but with the up rise of the different forms of communication the very backbone of the wired and wireless networks can come under attack without any warning,

The IEEE 802.11 is basically for the denial of service attacks and counter measures in wireless networks. The paper mainly focuses on security of 802.11 wireless networks. In this paper 802.11 standard is discussed with respect to frames types, contention resolution, physical layer convergence protocol (PLCP), Channels and security.
