Cybercrimes & Cyber Security
Cyber Security Cyber security is the most important computer technology needed in today’s society. Some people think that better computer design will be cost effective and provide protection to our bank accounts, social security numbers and driving records, but recent hacks like Equalfax which have put millions of people in jeopardy is the reason that cyber security is the most important.
Combating Cyber Crimes
Cyber Security protection must start changing for the better in today’s evolving world. Everyday there are new cyber threats and traditional approaches will no longer suffice to secure important data and information (“Cyber Attack,” 2016). Because

In 2012, the U.S. Department of Homeland Security cybersecurity had reported 52% more. They had 198 attacks that were brought to attention that were successful. A natural gas pipeline was targeted by a group of hackers, and they gained access to steal data on how their system works. The United States infrastructure is very vulnerable. The image below shows 7200 locations of industrial locations that are vulnerable to attack.
Combating Malware
Malware is basically the term for a software that main purpose is to do harm to a computer. The most widely known types of malware is the computer virus but there are plenty of other types of threats in the cyber world that is continuing to evolve.
Viruses are programs that attach themselves to legitimate programs with malicious intent. It is designed to spread from one host to another. Once a virus has successfully attacked, the program will remain dormant until the device has to execute its code. Once infected the computer virus can infect other devices on the same network and cause some major damage. These damages include corrupting files and even taking over the

Some examples of social engineering include phishing, spear phishing, and hoaxes. Phishing is where a victim receives messages that may or may not look real from actual business places. These messages ask victims to authenticate and give up sensitive information. Most people who fall for these tactics believed that the website or message was real. Spear Phishing targets a specific victim. Hoaxes are just ways to make the victim feel dumb that they fell for the trap. Lastly, we have spam, which is unsolicited commercial emails. Now a days filters have blocked a good amount of these emails because they are just annoying to deal with but spam has become the common transport for viruses, worms, trojans, and many other forms of
At this juncture, it may be somewhat difficult to accept the proposition that a threat to the telecommunications grid, both wired and wireless, in the United States could potentially be subject to a catastrophic cyber attack. After careful research on the subject, it appears the potentiality of an event of such magnitude, which either disrupts one or the other grids for a long period or destroys either, is both theoretically and realistically impossible. It may be that proponents—those who advance such theories—equate such “doomsday” scenarios as if a cyber attack would or could be of the same magnitude as a conventional or nuclear military strike. Terms such as “cyber Pearl Harbor,” “cyber 9/11” and “cyber Vietnam” have been used to describes potential catastrophic cyber attacks and yet, “Though many have posited notions on what a ‘real’ cyber war would be like, we lack the understanding of how such conflicts will be conducted and evolve.” (Rattray & Healey, 2010, p. 77). Yet, the U.S. government continues to focus on such events, as if the plausibility of small-scale cyber attacks were not as pressing.
Virus: Virus is a type of malicious software malware that replicates by reproducing itself to another program, document or computer boot sector.
A cyber attack has the potential to create extreme economic damage that is out of proportion to the low cost of initiating the attack. A successful cyber attack targets vulnerable computers, forcing them to malfunction or become disabled, whereby businesses, financial institutions, medical institutions and government agencies are not able to use them.
What is virus? A computer virus, according to Webster's Collegiate Dictionary, is "a computer program usually hidden within another seemingly innocuous program that produces copies of itself and inserts them into other programs or files, and that usually performs a malicious action (such as destroying data)". Two categories of viruses, macro viruses and worms, are especially common today. Computer viruses are never naturally occurring; they are always man-made. Once created and released, however, their spread is not directly under human control. One example of a virus is the Anna Kournikova virus, which comes in the form of a picture sent through email.
Most viruses are created out of curiosity. There are those out there who create them out of malice, but far more of the creators are just meeting a challenge, to see if they can do it or not. A common type of virus would be a Trojan Horse, a destructive program disguised as a game, a utility, or an application. When run a Trojan Horse does something harmful to the computer system, while appearing to do something useful. A worm is also a popular type of virus. A worm is a program that spreads itself across computers, usually by spawning copies of itself in each computer’s memory. A worm might duplicate itself in one computers memory so often that it causes the computer to crash. A worm is introduced secretly into a host system either for fun, or with the intent to damage or destroy information. Now I will explain some of the more major viruses, and how they function.
In today’s days malware is designated as a software which aims to disturb a computer with the consent or permission of the owner. This term “Malware” is used by computer professionals to describe a varied forms of destructive, annoying and intrusive software code. This word “Malware” is used to indicate all types of malware which include a true set of viruses.
What is the “MALWARE”? A malware refers to software programs designed to damage or do other unwanted actions on a computer system. In Spanish, "mal" is a prefix that means "bad," making the term "bad ware" .Malware includes viruses, worms, Trojan horses, and spyware. Viruses, for example, can cause havoc on a computer's hard drive by deleting files or directory information. Spyware can gather data from a user's system without the user knowing it. This can include anything from the Web pages a user visits to personal information, such as credit card numbers.
virus is a file infecting virus, when you run a file infected with that virus.
Malicious software in short known as Malware. It is also known as computer Contaminant. Similar to biological parasite, malware also reside in a Host. Malware will get installed on host without user’s consent. Generally a software is considered malware based on the intent of the creator...
Different authors have reviewed the cyber terrorism from different angles. Most of them have focused on the aims and objectives which terrorist wants to accomplish through cyber warfare. Moreover they have stressed over the need to the measures taken to combat cyber-attacks by terrorists.
Malicious software, or simply malware, can be described as software that a computer user never authorized to be loaded. This means that the software can be found on user’s computer without his or her knowledge. Furthermore, a malware can be described as software that collects private information from any computer without user’s knowledge and authorization. As the name suggests, this software is malicious and can do great damage to a computer, mobile device, or other related devices. This damage can range from something as slight as altering the author’s name on a document to massive damage like making an entire device fail to function properly (Töyssy and Marko 109). The good news is that malwares can be controlled or prevented. As a matter of fact, it does not cost a fortune to keep a device safe from malware attacks. It also needs enough knowledge about them. In order to be able to do this, however, it is important to understand the various terminologies used to describe malicious software.
Cyber security is the protection of networks, computers, programs and data from attack, damage or unauthorized access. This is important because a great number of our confidential information is on computers and transmit that data across networks to other computers. As of now cyber-attack is one of the transnational issues that we are concern about in the United States. If these private networks were hack our national security infrastructure will be in distress.
The problem this paper will endeavor to address is that of cyber security or the lack of it, characterized by the cybernation of our lives, which has increased our vulnerability to cyber-attacks. The scope of the threat posed by cyber insecurity will be addressed. How severe is threat posed by cyber criminals? How do they operate? The ramifications of cybercrimes and their impact on the economy are without a doubt cause for government. In addressing the problem, however, the government faces the dilemma of acce...
Firstly this report will look at the definition of a computer virus. This definition taken from Microsoft (n.d.) tells us what a virus is “Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.” This definition tells us that viruses are designed to spread from one computer to another this could be through email attachments sent between friends or a multitude of other methods. Viruses are also self-replicating this means that they multiply and affect more of the computer’s hard drive replicating itself to other programs on the hard drive once the virus is on a new part of the hard drive this section is then known as infected.
The nation has become dependent on technology, furthermore, cyberspace. It’s encompassed in everything we deliver in our daily lives, our phones, internet, communication, purchases, entertainment, flying airplane, launching missiles, operating nuclear plants, and implicitly, our protection. The more ever-growing technology empower Americans, the more they become prey to cyber threats. The United States Executive Office of the President stated, “The President identified cybersecurity as one of the top priorities of his administration in doing so, directed a 60-day review to assess polices.” (United States Executive Office of the President, 2009, p.2). Furthermore, critical infrastructure, our network, and internet alike are identified as national assets upon which the administration will orchestrate integrated cybersecurity policies without infringing upon and protecting privacy. While protecting our infrastructure, personal privacy, and civil liberties, we have to keep in mind the private sector owns and operates the majority of our critical and digital infrastructure.
