Underwater Wireless Communication Networks Are Affected By Multipath, Large And Variable Propagation Delays

During this presentation we learned of the network types that Whitewater uses and how they differ. For example they have three different networks which separate devices that are allowed to access the network. Their network gives each device a certificate that is good for 2 years. They also recently implemented a check in for devices accessing the network so that they can verify whether or not the user has an anti-virus installed.

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:

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

Providing for homeland security in the United States requires protection from a diverse set of threats. One prominent avenue of attack is via maritime routes, yet the nature of the coastal marine space makes it extremely difficult to detect and intercept smuggling vessels. Many sensing technologies exist for detection of seacraft, but there are few options for deployment of these sensors. Currently, such sensors are deployed on various manned vessels, tethered buoys, and aircraft. Development and testing of purpose built anti-submarine systems such as DARPA’s ASW Continuous Trail Unmanned Vessel (ACTUV) (more colorfully known as the “ghost hunter”), is underway but suffers from high cost.

“Use of the wireless is beneficial for ships because they are able to receive weather reports, check their positions, and call for help in emergencies [Society, 1977].”

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:

Abstract -This paper addresses the internal and the external security challenges in organizations that implements wireless networks. Distributed security is designed to provide a more secure data communication among faculty members, staff and students. A description of the technique used to protect and keep PC 's up and running is illustrated with applications.

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.

The new wireless radio system was used to send personal messages, but also to communicate with other ships. The Titanic’s watertight compartments were supposed to keep the ship floating if 4 of the compartments were flooded, but in the sinking, more than 5 were filled, so the ship sank.

Communications Security is critical to preventing adversaries from obtaining information traversing the internet. With today’s technology just about all information is being transmitted via the internet or phone lines or mobile radios. This can be anything from credit card payments for online purchases to classified secret level or above information for military operations. The technology involved in the area evolving crypto systems such as KG-175s, emissions security or TEMPEST requirements protecting emanations, physical security like ensuring material is accounted for, and transmissions security or protecting information from interception. To support the ever growing technology there is specific equipment and storage requirements for network traffic and voice traffic. There is even equipment devised just to manage and account for the encryption devices on the network. The companies and organizations overseeing communications security include the National Security Agency, General Dynamics, and the Committee on National Security Systems. Finally there are global implications for communications security. National Security Agency surveillance and cyber attacks are among the most relevant concerns in today’s communications security. First discussed will be the technology involved in the area.

Moreover, it is important to note that while cryptography is necessary for secure communications, this report is not by itself sufficient. The reader is advice then, that the topics covered in this paper only describe the first of the many steps necessary for better security in a number of situations.

Wireless devices, like all technologies that provide external access to corporate networks, present security challenges. With wireless standards and practices still rapidly evolving, it is important to understand the strengths and limitations of available technologies in order to implement a secure solution. Extending current security policies to encompass wireless devices requires an understanding of the security features of both wireless devices and wireless networks.

The last decade of this millennium saw an increment in the usage of wireless devices such as Bluetooth enabled devices that use wireless networks and smartphones with a wireless enabled feature that can allow users to access the internet from anywhere. All that is required is a place where the WLAN is accessible and then get connected using a username and password provided by ISP. WLANs have gained popularity globally as they are being used in places such as universities, airports, places of residence, cafes and so forth. They have numerous benefits such as mobility and flexibility compared to the traditional wired. As the popularity of its usage continues to heighten, it has become important to look at an aspect of security available for WLANS to prevent the network risks associated with this type of network. WEP is a security mechanism for WLANS that this paper will focus on much. The paper will discuss WEP and the weaknesses it has that make it prone to attack.

Today every wireless device uses frequency based transmissions without using any physical or wired connections. Wireless system consist of LAN(Local Area network), WAN(Wide Area Network), Personal networks, Wireless computers, smart phones, Tablets. It also consists of devices which have infrared and Bluetooth integrated in them such as wireless mouse and wireless keyboards. With the introduction of these technologies that are operated wirelessly requires a certain level of security as well. Thus these devices are to a level bit vulnerable to many conventional as well as other severe attacks. So wireless security is necessary to prevent all sorts of attacks. Basically Wireless Security is the prevention or restriction of unsanctioned or

Wireless networking has numerous benefits. Productivity remarkably enhances due to the higher accessibility to the information resource. Network configuration as well as reconfiguration becomes easier, quicker, and overall less expensive. Nonetheless, this technology also poses new threats as well as brings change in the already existing profile of risk in the information security. Explaining this terminology, as we all know that the communication occurs "through the air" utilizing the radio frequencies, the inception risk are higher in comparison to the wired networks. In case the messages are not encrypted, or just encrypted having a relatively weak algorithm, then the attacker could very well read it, hence compromising the confidentiality of the data. Though, the wireless networking changes the integrated risks with the various threats towards the security, the objectives of overall security remain all the same as they are with the wired networks: confidentiality preservation, ensuring integrity as well as maintaining the availability of information including information systems. This paper deals in assisting the concerned users of the wireless technology in performing sound decisions by inculcating them along with the basic understanding related to the some associated threats with the wireless networking as well as their countermeasures.
