Within the last decade, the internet has proven to be the most efficient way to complete tasks in today’s society. Every major business in today’s society relies on the internet to conduct business. Though the internet is a useful tool, our reliability on it opens up the door for cyber-attacks that can be detrimental to business as a whole. One example of a cyber-attacks that have recently started becoming more prevalent are DDoS attacks. Recently, DDoS attacks have been a rising issue for businesses owners who run their own servers, such as video game companies and other high profile web servers, including banks and other credit card payment gateways. A DDoS attack, distributed denial of service attack, is when one or more individuals attempt to force a network offline and unavailable to its intended users. This process is typically performed by flooding a network with communication requests until the server cannot respond to the traffic, thus making the server go offline and become available. This process is relatively simple to perform to the average person through online programs. Since it is so easy perform, it has become a rising issue simply because anyone has the ability to hack into various servers. One example in recent news of DDoS attacks comes from Riot Games, developer of the popular online multiplayer video game League of Legends. After a month of inconsistency with their server stability and frequent shut downs, Riot Games reported that within the l...
Synopsis: On 11-28-2015 at 1030 hrs. An Assault with a Deadly weapon occurred at 133 Industrial Way, San Jose/ Brother’s Inn (Men’s homeless shelter). Two clients (V- Rush and S-Lowe) get into a verbal argument in the day room of shelter. V-Rush borrowed $20 from the S-Lowe last month and paid him back last week, but today again suspect confront V-Rush to pay his money back, because of this they got into an argument. S-Lowe was drunk, so he starts hitting V-Rush on his face with both fists and he hit back. S-Lowe also took out a razor from his right side jacket pocket and swung it back and forth at V-Rush face and scream “I’m gonna cut you real good”. V-Rush backed up to save himself but he fell over into his back on the floor. S-Lowe stood
DoS attacks are defined as an effort to make a computer resource unavailable to its users. (Hackers usually use this type of attack on web servers for banks, credit card payment gateways or DNS root servers.) A DoS attack uses the IP address to flood the user’s network and obstruct the communication between the intended user and the victim. It has been proposed that a Shared Authentication Information (SAI) protocol could be used to offer a defense mechanism against DoS attacks, without incurring over- head at the ASN gateway and the base station.
RIOT can create lists of user comments and postings online for evaluation. However, it does not read a user’s private emails, though the federal government has been demanding this information from various firms. RIOT cannot mine the data files on your personal computer. However, the federal government has been arguing that data stored on the cloud isn’t “private” like data on a computer in your home, thus exempt from many of the protections granted to private papers. Internet security then only applies to the government itself, though it has a ...
"Information systems are vulnerable and it is possible for terrorists to utilize the vulnerabilities of information systems to attack their adversaries" (Hua & Bapna 2013). Since the events of 9/11 the world has watched as terrorism has slowly began to escalate not only in severity but frequency however, until recently nations including the United States have been more focused on traditional methods of terrorism and paid little effort to the growing concern of cyberterrorism. Hua and Bapta (2013) define cyberterrorism as:
Computer hackers use botnets or ‘zombie’ computers to infiltrate high security computer servers and minimize attempts to be caught. A botnet is a collection of internet-connected computers that are controlled by a computer hacker that did the original infecting. “As well as using the computers they land on to spread themselves further, they're designed to take control of them, either to steal confidential user information or to convert them into remote-controlled 'zombie...
The job of NBA is to enhance the security and to determine any unusual actions in the network which could lead to DDos attack. It monitors everything which are causing any rare traffic flow and mark any rare activities on the network. It has the best potential to monitor any change in bandwidth and to find any dangerous website which may have an impact on the network (Beal). It leverages the time of administrator to take care of issues which are detected. In addition, it is always a good idea to have more bandwidth because it gives the users more time to defend their network even if DDos attack is still going to occur but it extends the
The members of the aforementioned organizations are primarily peaceful and seek redress via nonviolent means. However, as with any highly charged political issue, the issues that drive these organizations to take to the streets has the potential to attract lone-wolf fringe individuals who may use violence to address perceived injustices. The FBI defines lone wolf attackers as “a single individual driven to hateful attacks based on a particular set of beliefs without a larger group’s knowledge or support” and that “most domestic attacks are carried out by lone offenders to promote their own grievances and agendas”. (FBI, 2009) Furthermore, it is difficult to define, categorize, or pattern such individuals, as they can “run the gamut, from hate-filled
The term “cyber terrorism” refers to the use of the Internet as a medium in which an attack can be launched such as hacking into electrical grids, security systems, and vital information networks. Over the past four decades, cyber terrorists have been using the Internet as an advanced communication tool in which to quickly spread and organize their members and resources. For instance, by using the instantaneous spread of information provided by the Internet, several terrorist’s groups have been able to quickly share information, coordinate attacks, spread propaganda, raise funds, and find new recruits for their cause. Instantaneous and unpredictable, the technological advantages these terrorists have obtained from using the Internet includes

...ng it, crashing it, jamming it, or flooding it. Denial of service is impossible to prevent because of the distributed nature of the network: every network node is connected via other networks, which in turn connect to other networks. A firewall administrator or ISP has control of only a few of the local elements within reach. An attacker can always disrupt a connection "upstream" from where the victim controls it. In other words, someone who wants to take a network off the air can either take the network off the air directly or take the network it connects to off the air, or the network that connects to that network off the air, ad infinitum. Hackers can deny service in many ways, ranging from the complex to the brute-force.
Unequivocally speaking, the threat of a cyber-attack has become one of the most critical domestic and national security challenges we face as a nation today. Infrastructures supporting government operations are ...
A firewall is a network device, hardware, software, or a combination of the two, whose purpose is to enforce a security policy across its connections. It is comparable to a wall that has a window where the wall serves to keep things out, except those permitted through the window. A security policy acts like the glass in the window; it permits some things to pass, light, while blocking others, air. The heart of a firewall is the security policy that it enforces.
Recently, the Internet has become the most significant technology in all over the world, which is not only used by the people to contact with each other but also utilized by the business organizations to become global (Taylor, Caeti, Loper, Fritsch & Liederbach, 2006). Computer and internet enable the business organizations to execute the Electronic commerce business model, which has become very popular. Computers and Internet are a powerful source in the success of globalization and international business. Computers are being used worldwide and due to this, cyber crimes are increasing continuously with a rapid growth (Cheeseman, 2006).
A cyber crime called 'Bot Networks', wherein spamsters and other perpetrators of cyber crimes remotely take control of computers without the users realizing it, is increasing at an alarming rate. Computers get linked to Bot Networks when users unknowingly download malicious codes such as Trojan horse sent as e-mail attachments. Such affected computers, known as zombies, can work together whenever the malicious code within them get activated, and those who are behind the Bot Networks attacks get the computing powers of thousands of systems at their disposal.
