Information Disclosure and Cybercrime

With the rise of the internet, some people argue that privacy no longer exists. From the 2013 revelations of government surveillance of citizens’ communications to companies that monitor their employees’ internet usage, this argument seems to be increasingly true. Yet, Harvard Law professor Charles Fried states that privacy, “is necessarily related to ends and relations of the most fundamental sort: respect, love, friendship and trust” (Fried 477). However, Fried is not arguing that in a world where privacy, in its most simple terms, is becoming scarce that these foundations of human interactions are also disappearing. Instead, Fried expands on the traditional definition of privacy while contesting that privacy, although typically viewed

An educational institution, such as this preschool, should take the security of both systems and networks seriously. Modern technology has so many benefits for helping educators teach young children, but also potentially harm so many individuals and families if good security protocols are not followed. A security breach has the potential of exposing sensitive data about students, their families and staff. With a wealth of information cyber defenses in academia is worse than healthcare because academia is not prepared to practice attentive and organized cyber intelligence (Polancich, 2015). Crimes such as identity theft, kidnapping, extortion, and sex assaults against children are only a few of what could potentially occur if physical and information technology security are not taken seriously. A breach could also bring negative publicity and possible legal ramifications with possible lawsuits against the institution and/or staff, as well as losing government and private funding. This in turn can affect enrollment, ability to hire and keep good teachers and other staff and remain an open educational institution. A staff made up of approximately 200 teachers, office personnel, administrators and executive staff ethical behavior should be a priority. Families entrust teachers and staff members with their children and sensitive information. If any staff personnel acts in an unethical way much of this information can be compromised

Figure 8.3(a) demonstrates a portion of a wireless ad hoc network where a source node S has a data packet to be sent to a destination node that is

3.2. BlackHole. In this attack,malicious nodes advertise very short paths (sometimes zero-cost paths) to every other node, forming routing black holes within the network [41]. As their advertisement propagates, the network routes more traffic in their direction. In addition to disrupting traffic delivery, this causes intense resource contention around the malicious node as neighbors compete for limited bandwidth.

In the location-based routing, sensor nodes are distributed randomly in an interesting area. They are positioned mostly by utilizing of Global position system. The distance among the sensor nodes is evaluated by the signal strength obtained from those nodes and coordinates are computed by interchanging information among neighbouring nodes. Location-based routing networks are;

 Generic Attacks against Routing: Routing is very important function in MANETs. It can also be easily misused, leading to several types of attack. Routing protocols in general are prone to attacks from malicious nodes. These protocols

In this example, here node A wants to send data packets to node D and starts to find the shortest path for its destination, so if node D is a malicious node then it will show that it has active route to the specified destination. It will then send the response In the example, data packets transfer in a hierarchic data center network. The link capacity is 1000 kb/s. The number on each is the traffic load. The distribution of traffic is based on equal cost multi-path (ECMP). In figure 8, we can see that the 3). Congestions

This protocol use Dijkstra algorithm. It maintains a complex data base, also called as link state database, which contains full information about the remote routers and the exact network topology. The goal from this protocol is to provide similar information about network connection to each router, so each router can calculate the best route to each network this is happen when each router generates information about itself and pass these information to other routers in the network so each router make a copy of this information without changing it.

(b) Redirection with modified hop count: This type of attack is targeted against the AODV protocol in which a malicious node can increase the chances that they are included on a newly created route by resetting the hop count field of a RREQ packet to zero. [17]

Cyber Crime is described as criminal activity committed via use of electronic communications with respect to cyber fraud or identity theft through phishing and spoofing. There are many other forms of cyber-crime also such as harassment, pornography etc. via use of information technology.

Cyber crime is defined as any crime that involves a computer and network. Individuals, businesses and government agencies around the world constantly face threats to their medical information, consumer data, as well as company trade information and military decisions. Cyber security specialists are professionals that are specifically trained to protect individuals and organizations from cyber crime, hackers and scammers.

Most of the current approaches are limited by focusing on enforcing anonymity at a heavy cost to precious resources because public-key-based encryption and high traffic generate significantly high cost Vehicular Ad Hoc Networks (VANETs) and Mobile Ad Hoc Networks (MANETs) use anonymous routing protocols that hide node identities and/or routes from outside observers in order to provide anonymity protection. However, existing anonymous routing protocols relying on either hop-by-hop encryption or redundant traffic either generate high cost or cannot provide full anonymity protection to data sources, destinations, and routes[7].

The Internet is a connection of computers across the world through a network. Its origin dates back to the 1960s when the U.S Military used it for research, but it became more available to the public from the late 1980s. The World Wide Web was created in 1989 and browsers began appearing in the early 1990s. Over the last 24 years, the Internet has enabled people to shop, play, do research, communicate and conduct business online. It has also become cheaper and faster in performing different tasks. As much as the Internet has done immeasurable good to society, it has also dominated people’s lives and brought with it an array of cybercrimes. According to Nicholas Carr in his book The Shallows: How the Internet is Changing the Way we Think,

Abstract—Mobile Ad-hoc Network (MANET) is a kind of wireless network. A Wireless ad-hoc network is a temporary network with no network infrastructure. The nodes communicate with each other, they co-operate by forwarding data packets to other nodes in the network. Thus the nodes find a path to the destination node using routing protocols. Due to the security vulnerabilities of the routing protocols, wireless ad-hoc networks are unprotected to attacks of the malicious nodes. One of these attacks is the Sinkhole Attack. Sinkhole attack is a kind of routing attack in MANET. A sinkhole node tries to attract all the network packets to it-self from all neighboring nodes. This paper focuses on to detect and prevent sinkhole node. By using a hybrid detection technique which combines the advantages of both reactive and proactive routing Protocol to detect the
