The jamming attackers normally hinder the signal reception by preventing a real server from conveying information or by avoiding the function to genuine packets. Considering this, the various models adopted by jammers is the constant discharge of radio signals, the introduction of a regular package to the channel without any breaks between ensuing packet broadcast and alternation between inactivity and jamming (Xu, et al, 2005). This implies that a jammer will continually send radio signals to interact with data submissions, causing delays in the systems. The introduction of a regular package to the channel is detrimental because it activates a system to a default mode that does not portray the current activity (Xu, 2007). For instance, if a node can be set to remain in the receive style regardless of whether it is sending or not doing so.
The alternation between inactivity and jamming is that the system is automatically set to be inactive and resume operations after a certain time (Xu, et al, 2005). This makes the system to be in the attacker’s default mode or experience delays. Another jamming mode is the employment of a reactive strategy in which the jammer does nothing when the channel is idle and assumes operation upon the detection of signals. A receptive jammer targets the response of a message to execute the attack.
Although most jammers use varied models for their missions, users should always monitor their wireless for possible attacks. This implies that they need to install necessary detection mechanisms that enhance the safety of their devices. The first detection measurement is checking the signal strength to determine the presence of unusual scenarios in the system. This employs gathered ...Download file to see next pagesRead More

Detecting Bias

...English 306 Detecting Bias Assignment Some people argue that bias destroys the passage written and denies the other side of the picture completely. However, this is not true for all writers and contexts. Bias helps us in building our views and opinions about certain issue or individual. A biased statement does not necessarily stops us from thinking ahead but provides people with a chance to accept or refute that point of view. Biased statements help us in thinking, analyzing and examining certain claims which may or may not be true in our opinion. This paper aims to analyze the article written by Catherine Porter and titled as “Lessons of the Montreal Massacre: Why women must fight to be what they want” for bias and the...

Cyber attacks

...Technology has been evolved with new research and reinventions facilitating the critical infrastructure computerized. On the other side, vulnerabilities also emerged causing disruption to the critical infrastructure impacting in several ways. Although there are many vulnerabilities, cyber attacks are the most prominent one. Cyber attacks approach the target in a non traditional way. Due to inequity in the military strengths, hackers attack this critical infrastructure affecting both the economy as well as the military sector of the country (SANS: Critical infrastructure protection). It could be operated by the government or the private sector, both Networks provide opportunities for...

...Culture Jamming Culture Jamming Cultural Jamming is an idea supporting anti-consumerism that aims to disrupt and undermine the media culture and the areas where it is being utilized including the corporate advertising. Culture jamming is often used as a means to “subvertising”, i.e. making parodies of the existing corporate advertisements by either altering their existing logos and ads or creating new images that target the best known brands among the many. According to culture jammers, it intends to emphasize the personal freedom of consumers and the domination of society instead of domination of corporations and brand names. One of the culture jammers depicted in the...

Detecting preventing or mitigating DoS or Distributed DoS attacks

...Techniques for Detecting, Preventing or Mitigating Distributed Denial of Service (DDoS) s s Introduction When using the internet, individuals and companies face a threat from attackers with the aim of depleting internet resource in their target network (Patrikakis, Masikos, & Zouraraki, n.d.). The weakness they utilize is the nodes from the interconnectedness of world computers in a worldwide web, which makes it possible for them to access resources on their target, exhaust them and launch a DDoS attack against them (Glen, 2013; Nagesh, Kordcal, & Sekaran, 2007). The resources targeted by the attacker are their target`s bandwidth, data structure of their operating system...

Culture Jamming

...due: Culture Jamming While culture jamming mostly concentrates on parody and criticism, some jammers tend to be optimistic, getting innovative and creating cultural products that surpass criticism, bringing artists together to improve on general art. Culture jamming is the act of hijacking billboards meant to communicate a marketing message for an individual product or alter advertisements giving a different message. Jammers mostly argue information they alter is uncalled for or is not healthy for the community. Jamming has grown over the years from low tech, e.g. use of spray paint to medium tech and finally high tech e.g. Photoshop and interceptions-counter-messages....
