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:

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.

In this report I will be describing the ways in which networks can be attacked, also be giving real life example of each of the below.

Undoubtedly, this paper will generate network information, diagrams, and/or tables; accordingly, these are all included in the Appendix section of the paper. Moreover, the training, vulnerability assessment, and SAQ results are also included as an Appendix in the final paper. Finally, fearing disclosure of proprietary information that could compromise network security, all project data are scrubbed and sanitized to remove sensitive information.

The vulnerabilities of wireless networking may involve the attack of web browsers, on-line banking, DNS servers, and routers exchanging routing table updates, purchases, transactions or stolen personal data. The lack of security with a wireless system may result in denial of service, hijacking, fake impersonation, or eavesdropping for interception of messages through cyber-crimes. Each communicating user should select the language of cryptography, agree and share the symmetric key. The best security practices includes firewalls, intrusion detection systems, secured and updated applications, transport, configured properly working network, and link layers.

The various papers on the recent explorations and growth in the field of Wireless Sensor Networks and attacks in WSN’s have been reviewed and discussed below:

To better understand the mechanics of the communications system, it is important to highlight how the physical, network, communications, and administrative security components mitigate risks that hinder the system. The key to physical security is to prevent potential breaches to facilities where communications systems are located. This includes policies and measures to protect the physical facilities where the “communications center, remote tower sites, maintenance facilities, as well as the communications equipment itself” are stored (p.

Within this article, the authors states that in order to provide a safe and secure wireless network, they outlined the counter attacks and measures for the security of wireless networks. Some of the counter attacks that the authors have listed includes, system security - which breakdowns to administrative level security, physical level security, and technical level security, and information security (Ameen et al, 2012). For the purpose of answering the previous question, the main counter attack that would best defend against the problems would be system security - particularly the administrative level security. At this level of security, administrative control over the system by establishing a well defined user hierarchy plus a strong authentication measures, can prevent security breaches of WLANs from

“Wireless security isn’t just a big issue for control systems, but for all uses, mainly because wireless is becoming so pervasive,” says Staggs. “It’s very easy to plug wireless in almost anywhere. However, you have to be able to find the signals and know if someone has put in a rogue point.

For this coursework I have decided to perform a penetration testing against “My House lab”, to evaluate and improve my WLAN Infrastructure security.

Wireless networks have grown in popularity. This is largely due to the increase in the value of a network as more users are attached to it. The value added to a network by nature of connecting more devices to it, is summarized in "Metcalf's law." Metcalf's law states that if you "connect any number, ‘n,' of machines - whether computers, phones or even

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,

security mechanisms are discussed. Underwater wireless communication networks are particularly vulnerable to malicious attacks due to the high bit error rates, large and variable propagation delays, and low bandwidth of acoustic channels. A complete survey of securing underwater wireless communication networks is presented, and the research challenges for secure communication in this environment are outlined.Acoustic channels have low bandwidth. The link quality in underwater communication is severely affected by multipath, fading, and the refractive The unique characteristics of the underwater acoustic communication channel, and the differences between underwater sensor networks and their ground-based counterparts require for the development of efficient and reliable properties of the sound channel. As a result, the bit error rates of acoustic links are often high, and losses of connectivity arise.Radio waves do not propagate well underwater due to the high energy absorption of water. Therefore, underwater communications are based on acoustic links characterized by large propagation delays. The above mentioned characteristics of UWCNs have several security implications. UWCNs suffer from the vulnerabilities which decreases the reliability. So, this article have discussed for security in UWCNs, underlining the specific characteristics of these networks, possible attacks, countermeasures and challenges.

The electronic systems in the network are also vulnerable to HPM attacks. The enemy can comfortably blind forces to allow attacks by disabling key nodes in a sensor network for a considerable time period. This vulnerability though is limited to a range and needs high energy towards the target
