In computer security, a vulnerability is a weakness which allows an attacker to reduce a system 's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness. In this frame, vulnerability is also known as the attack surface. (Wikipedia).
With this previous definition we can assume that a threat occurs when a weakness is Identified and attacked from an outside source for malicious purposes. By doing things like threat assessments we can tell the best course of action to take before the problem

Used by hackers for espionage purposes, it infected other systems over a local network (LAN) or USB stick including over 1,000 machines from private individuals, educational institutions, and government organizations. It also recorded audio, including Skype conversation, keyboard activity, screenshots, and network traffic. It was discovered on May 28, 2012 by the MAHER Center of Iranian National Computer Emergency Response Team (CERT), the CrySys Lab and Kaspersky Lab. …show more content…
This involved a number of hijacked computers that caused servers to overload due to the flooding of traffic called DDoS attack. The numbers of hijacked computers varied depending on the sources and include 50,000 from the Symantec’s Security Technology Response Group, 20,000 from the National Intelligence Service of South Korea, and more than 166,000 from Vietnamese computer security researchers as they analyzed the two servers used by the invaders. The Canadian government has revealed in news sources that they became a victim of cyber-attacks in February 2011 from foreign hackers with IP addresses from China. These hackers were able to infiltrate three departments within the Canadian government and transmitted classified information back to them. Canada eventually cut off the internet access of the three departments in order to cut off the transmission towards China. PayPal became a victim of cyber-attack in December 2010 after it permanently restricted the account used by WikiLeaks to raise fund, citing their violation of the Acceptable Use of Policy as their reason. However, it did not only result in multiple boycotts from individual users but also caused hackers to move in. The biggest protest movement against the Church of Scientology was conducted by Anonymous,
All information obtained about an IP address from where authorities suspected the worm had came from led them to obtain a search warrant on a individual on August 19, 2003. On that day, FBI and USSS Special Agents seized seven computers throughout the household. The individual in question, Jeffrey Lee Parson, admitted to agents that he modified the Blaster worm and creating a variety of them including one named, W32/Lovesan.worm.b. Within the worm he placed code that would direct computers to his personal website, www.t33kid.com, so he could maintain a list of compromised computers.
"The next step is to determine the impact that the threat could have on the organization. It is important for auditors to understand that not all threats will have the same impact. This is because each system in the organization most likely will have a different value (i.e., not all systems in the organization are worth the same or regarded in the same way). For instance, to evaluate the value of a system, auditors should identify the processes performed by the system, the system's importance to the company, and the value or sensitivity of the data in the system" (Edmead). To understand the important of a risk helps point out the businesses weaknesses. It is important that the degree of impact caused by different risks are determined. The
Historically, the Anonymous has been engaging in activities that qualifies the group as hacker group as opposed to troll organisation. The group began its operation on December 2010 by attacking the MasterCard for blocking the Wiki Leaks website donations (Coleman 1). In January 2011, the Anonymous group attack the Tunisian government website for using illegal means against protesters. In February...
The Defense Department made an admission of the first major cyber attack upon its systems in August 2010. It was revealed that the attack actually took place in 2008 and was accomplished byplacing a malicious code into the flash drive of a U.S. military laptop. “The code spread undetected on both classified and unclassified systems, establishing what amounted to a digital breachhead.” (2) This quote , attributed to then Deputy Defense Secretary William J. Lynn III , is just part of the shocking revelations that were disclosed in his speech made on July 14, 2011. Lynn said that...
In contrast, while machines will never reach a status where they can be considered conscious, emotional, and intelligent humans, they still possess a bearing advantage over humanity. Humans are inherently extremely susceptible to influence taking a negative tolls on their lives. Humans are vulnerable, frail, and exposed; traits that machines will never have to deal with. Such an advantage would normally be considered as a good aspect, but this same advantage also serves as a crucial detail when differentiating human beings and machines. Self augmenting machines might at some point reach a status where they meet the seven biological characteristics, which are “cell composition, organization, energy usage, environment awareness, growth, reproduction,
A lot of people usually get tired of hearing about Shakespeare and “blank verse” this, or “literary genius” that, but when one stops to actually evaluate it, Shakespeare’s Macbeth is more than just a tale about a power-hungry thane that kills to take the throne. As Shakespeare uses sleep imagery, characters who gain power become more and more vulnerable. When these characters fight for power, they become too vulnerable, and usually end up dying. Finally, as the characters struggle to remain strong throughout the play, sleep imagery begins to show the weaknesses the characters didn’t show otherwise. By examining Shakespeare’s use of sleep imagery, one can determine that all characters are vulnerable, even those who are most powerful.
The use of hacking to identify weaknesses in computer security has become an increasingly controversial issue in recent years. Awareness of this issue is important, because our ever increasing reliance on technology means that breaches in computer security have the potential to have wide-ranging and devastating consequences to society, worldwide. This essay will begin by clearly defining the term ‘hacking’ and will examine the type of people who hack and for what reasons. There will then follow a discussion of the moral argument on hacking before examining a few brief examples. The essay will then conclude by arguing against the use of hacking as a means of identifying weaknesses in computer security.
Vulnerability derives from the Latin word vulnerare (to be wounded) and describes the potential to be harmed.
Cyber Warfare is definitely the future, like any other advancement in technology; where there is potential to harm and pacify our enemies, we will exploit it. Cyber warfare or cyber weapons are no different from any other advancements. Like the boat, airplane, and nuclear energy before it computers will and have been used as a weapon, a tool from which nations can conduct war against their enemies, joining rank with forms warfare we are already accustomed to. What makes cyber warfare different from these established forms of warfare is its capabilities and clandestinely.
National security in the United States is extremely important and requires extensive risk management measures including strategic, exercise, operational and capability-based planning, research, development, and making resource decisions in order to address real-world events, maintain safety, security and resilience (Department of Homeland Security [DHS], 2011). The national security and threat assessment process consists of identifying the risk and establishing an objective, analyzing the relative risks and environment, exploring alternatives and devising a plan of action for risk management, decision making and continued monitoring and surveillance (DHS, 2011). Identifying risks entails establishing a context to define the risk, considering related risks and varying scenarios, including the unlikely ones, which then leads to the analysis phase; gathering data and utilizing various methodologies and analysis data software systems to survey incidence rates, relative risks, prevalence rates, likelihood and probable outcomes (DHS, 2011). These two key phases lay the foundation to explore alternatives and devise action plans. Threats, vulnerabilities and consequences (TCV) are also a key component of many national security risk management assessments because it directly relates to safety and operation capabilities, but the text stress that it should not be included in the framework of every assessment because it is not always applicable (DHS, 2011).
What is vulnerability? When asked such a simple question, very few people know how to answer in a way that can narrow the broad topic of “being vulnerable” into a clear statement. The reason that is it so hard to explain what vulnerability truly means is because there are so many different ways that the word can be looked at. Vulnerability can be narrowed down into groups of physical, economic, social, and environmental. All of these narrowed down topics have the main theme of hazardous impacts on people, places, and things, but, when in the event of a natural disaster, each of these different types of vulnerabilities can effect an individual in extremely different ways.
There has been significant advancement in the field of science and technology over the past few decades. These advancements made it possible for us to accomplish the impossible work in no time. Although, these developments may offer many benefits, but it is also a disadvantage for our daily lifestyle. Furthermore, people tend to spend most of their time on the technology such as phones, computers, etc. These devices can be very handy in order to do online shopping or any other personal work; however, they do not know that doing online shopping or any other personal work can turn into a nightmare. These personal devices are not safe while we are browsing on the internet and even people are aware of it, they are not doing anything to prevent
Cyberterrorism costs companies, goverments and everday people billions of dollars each year. "Cyberwar may be to the 21st century what blitzkrieg was to the 20th (Arquilla)." In 1994, a Russian hacker broke into CitiBanks funds transfer system and transferred

The Art of exploring various security breaches is termed as Hacking.Computer Hackers have been around for so many years. Since the Internet became widely used in the World, We have started to hear more and more about hacking. Only a few Hackers, such as Kevin Mitnick, are well known.In a world of Black and White, it’s easy to describe the typical Hacker. A general outline of a typical Hacker is an Antisocial, Pimple-faced Teenage boy. But the Digital world has many types of Hackers.Hackers are human like the rest of us and are, therefore, unique individuals, so an exact profile is hard to outline.The best broad description of Hackers is that all Hackers aren’t equal. Each Hacker has Motives, Methods and Skills. But some general characteristics can help you understand them. Not all Hackers are Antisocial, PimplefacedTeenagers. Regardless, Hackers are curious about Knowing new things, Brave to take steps and they areoften very Sharp Minded..
