Both Kismet and Wireshark are excellent network analyzers. Wireshark possesses a complete packet in terms of collection, visualization, and easy user interface. Kismet provides location services, is small enough to run in small sensors and can be highly mobile. Also, the server/client mode allows for multiple operators to analyze the live capture simultaneously, making it the best tool for the task. Collecting information with Kismet requires familiarization with the software, but once completed the possibilities are diverse. For example, a small single chip computer or sensor placed on a strategically located area near wireless points can locate a user in the
The Netsilik and the Chipewyan were both tribes that lived in really tough area with extreme low temperature and a lot of ice that doesn’t allow any kind of farming. These tribes rely on deer hunting a lot and the process of using the meat is handled by women. Any kind of sewing, cooking or preparation of the meat to be used is done by women, but even though women have a big role in the post hunting life in both of these communities, they have quite different roles. First, they approach kinship in two different ways. The Netsilik have a bilateral descent system, which is similar to what we have in the United States today, but not completely. Netsilik have personal kindreds which are blood relatives of a person on his or her generational level which we don’t have. The Chipewyan system is
This can give you the IP address, MAC address and vendor on machines. Then one runs the Nmap -A xxx.xxx.xxx.xxx* command with the same address range to obtain the operating systems on those same range of machines and what application version it is. This also gives the open ports and what services are running on them. Now the IP, MAC address, vendor, port information, services, Operating system and the version are known. After all this information is known, one can utilize a mapping tool such as Solar winds that can give an actual picture representation of the network to visualize things. Next is enumeration to discover more specifics such as user accounts, group settings and application settings. Depending on the OS, version and if NET Bios is enabled, one could use null sessions to find lists of machines, shares, users, groups, and users/host ids. Using the Windows command line, type:

KNX had several newscasts within the hour.
Geographic profiling uses information that relied on a management system that primarily demonstrate the methodology that evaluates where the crimes occurred in the area, to find the exact location of the criminal hotspot. It has many strengths and weakness that can be used to target a wanted criminal, however it needs precise accurate information to be valid in capturing the offender. It can be greatly helpful in many crimes such as rape, homicide, arson, terrorist activity, robbery, and kidnapping. It is a theoretical crime model that focuses on the individual profile that matches him with who the offender associates with, his profession, and where residence is located. Every individual has precise movements and this model directly attacks their patterns or activities.

A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
The propose research will address a problem confronting many two year institutions in the present-day (i.e. how to best plan, design, and implement WLAN technologies). While WLAN technologies offer the benefits of mobility, reduced installation time, and decreased cost, many challenges must be met by institutions deploying them (Geier, 2005). These issues are related to security, speed, interoperability, and equipment selection, ease of use, reliability, signal interference, installation, and health risks.
Wi-Fi facilitates ease of use and is getting increasingly popular with homes and businesses. Multiple Wi-Fi Access Points can be located in a given area. Wi-Fi security issues continue to be a problem, as the number of Access Points grows.
There are numerous network security devices and tools available to aid in computer network defense, and these tools are often relied upon for protecting against increasingly sophisticated, stealthy, and damaging attacks. When acting alone, the current generation of security devices has an exceedingly difficult time providing an effective defense against such threats, and the situation is particularly grim for targeted or novel attacks.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
This paper is going to discuss wireless security from a broad view where I will go into why wireless security is so important, especially today as the ways in which we communicate is changing dramatically. From there I will discuss the multiple wireless security options that are available to give a better understanding of the options given. Then I will go into why exactly not protecting your wireless can be so dangerous with some descriptions on the most dangerous wireless attacks out there today. Finally, I will then discuss how we can better prepare for these types of attacks with a synopsis on several effective security methods that will help to ensure data is securely passed and kept hidden. Wireless is everywhere today whether at home working from your WIFI network to work where you might be linked to a wireless network or even through your phone through a 3G or 4G network to connect to an open wireless network.
Networks in organisation are dynamic and complex entities which can be quite challenging to configure and manage. (Kim & Feamster 2013). These corporate networks consist of multiple routers, switches, firewalls, middleboxes and a particular advantage of network management is the ability to monitor the entire business network. As all the devices are interconnected with many event occurring simultaneously, problems with once device can eventually lead and spread throughout...
Harmful usage of a sniffer is catching password and also capturing special and private information of transactions, like username, credit ID, account, and password, recording sending of email or messages and resuming the information, Some Sniffers have the ability to modify the computer's information also to the extent of even damaging the system. Weakening the security of a network even being successful in gaining higher level authority. With everyday more and different hackers using of packet sniffers, it has become one of the most important tool in the defence of cyber-attacks and cyber-crime. Writted by (2001 – 2014) Colasoft LLC
