Research Critique The ability of the attackers to rapidly gain control of vast number of Internet hosts poses an immense threat to the overall security of the Internet (Staniford, Paxson & Weaver, 2002). Once compromised, these hosts can not only be used for massive Distributed Denial of Service (DDoS) attacks, but also steal or corrupt great quantities of sensitive information by confusing and disrupting the network in more subtle ways (Honeynet, 2005). The attackers accomplish this task by sending an intrusion agent commonly known as worm'. There are "two major types of malicious codes in the wild" (Todd, 2003, pp. 2). These codes are differentiated by their means of propagation: worms are self-replicating, self-propagating, whereas, viruses require some form of human interaction. Much like biological viruses cause disease in humans by compromising their body defence mechanism, a worm can not only damage or shut down host or networks but they are also mutating and becoming more complex. Worms can carry payloads designed for specific malicious intent (Todd, 2003). According to Geer (2005) there is a less familiar threat that many experts say could be just as dangerous: malicious bot software. According to Nazario et al. the evolution of the Internet worms will prove to be more difficult to identify and eradicate (Nazario, Anerson, Wash & Connelly, 2001). Hackers can install bots on multiple computers to set up "Malnets" or "Botnets" that they can use for massive DDoS attacks. Network security experts identify and shut down Malnets with 10 to 100 compromised hosts several times a day. Large malnets with 10,000 compromised hosts are rare but they still happen weekly, besides security investigators have found one malnet of ... ... middle of paper ... ...ENIX Security Symposium (Security '02).

Beal, V. (2011, March 29). The difference between a computer virus, worm, and Trojan horse.
The malicious software can lock the data in a way that is not difficult for an expert to reverse (Ali 89). Nevertheless, there is a more advanced method that involves the use of cryptoviral extortion to encrypt data and demand a ransom to decrypt the data. In such case, it is difficult for experts to recover files without a decryption key (Ali 89). Ransomware attacks are normally executed using a Trojan or a file that is disguised as an email attachment that seems legitimate to the user. In the last five years, ransomware attackers were able to target multiple computers through the use of a botnet (Ali 88). A botnet enables cyber criminals to attack an entire system by compromising the network. The ability to kidnap multiple systems makes ransomware a significant cyber security threat. The cybercriminals demand ransom in the form digital currencies such as bitcoins and ukash because they are difficult to
...at proposed a new Worm Interaction Model which is based upon and extending beyond the epidemic model focusing on random-scan worm interactions. It proposes a new set of metrics to quantify effectiveness of one worm terminating other worm and validate worm interaction model using simulations. This paper also provides the first work to characterize and investigate worm interactions of random-scan worms in multi-hop networks (Tanachaiwiwa and Helmy, 2007). For the best possible solution against cyber attack, researchers use Mathematical modeling as a tool to understand and identify the problems of cyber war (Chilachava and Kereselidze, 2009). Such kind of modeling is supposed to help in better understanding of the problem, but to allow such models to be practically workable, it is extremely important to provide a quantitative interface to the problem through the model.
Denial of Service attacks (DoS) or Distributed Denial of Service Attacks (DDoS), have been around for many years, but only in the past few years have the frequency and magnitude of these attacks increased. They are a significant problem because they can shut an organization off from the Internet for extended periods of time and little can be done to stop them. DoS attacks occur when computer resources become unavailable to legitimate users after being exhausted by false requests for information (Houle and Weaver 1).
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.
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
Society has become ever-increasingly dependent upon technology, more specifically, computers to conduct personal and business transactions and communications. Consequently, criminals have targeted these systems to conduct information and cyber warfare, which can include politically motivated attacks and to profit through ill-gotten means. In an article written by Koblentz and Mazanec (2013), cyber warfare is the act of disabling an enemy’s ability to use or obtain information, degrade its ability to make decisions, and to command its military forces. Additionally, information warfare is composed of cyber warfare and related to the protection, disruption, destruction, denial, or manipulation of information in order to gain a benefit through the technologies (Taddeo, 2012). Accordingly, as technology becomes readily available to various entities, the ability to conduct or perform warfare through technological means is multiplying.
“ Prevention is better than cure ”, if computer users are aware of Malware attacks, they may prevent those attacks . So, in this research paper i am going to focus on Malware and Protecting Against Malware.
Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors. In fact, according to several studies, more than half of all network attacks are waged internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, an...

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, Read and Remember (Carr, 2010). He debates on whether the Internet has done more harm than good. People use the Internet daily to exchange accurate information and constantly personal data such as credit cards, passwords and Social Security numbers are travelling through the network from one computer to another. With security measures put in place on the Internet, personal information remains confidential. But unfortunately, criminals have adapted to innovations in technology, and today, more people are increasingly becoming victims of cybercrime. The Internet has had profound effects on the public, both positive and negative. In this paper we will examine how access to personal information has led to an increase in online and offline crimes. The essay will particularly focus on ecommerce and hacking.
Malware can survive in a number of ways say different sizes, shapes and also the purpose ranging from viruses to spyware and to bots. Malware in general is classified into two types. They are the concealing malware and infectious malware. In case of infectious malware, the malware code is said to spread all over which means that the software code shall replicate from one user to another and this goes on. In infectious malware, we need to consider two cases, which are called the viruses and the worms. Viruses are termed as the software that has executables within itself and causes the executables to spread when it is run. The second case called worms is a software which infects a computer and then spreads to others.
The internet offers high speed connectivity between countries, which allows criminals to commit cybercrimes from anywhere in the world. Due to the demand for the internet to be fast, networks are designed for maximum speed, rather than to be secure or track users (“Interpol” par. 1). This lack of security enables hacker...
