An attack is any malicious or accidental disruption in the confidentially, integrity, or availability of information and network resources. Attacks can come from many places, electronic, physical, or human. Electronics attacks may come from the external network (Internet) or the internal network (Intranet); physical attacks can come in the form of hardware and equipment sabotage or theft, and human attacks most often come in the form of social engineering. Some of the attacks identify and evaluate in this paper are: spoofing, replays attacks, access attack suppress-relay, and source and repudiation attack.
Spoofing is when the attackers attempts to appear to be someone else, usually an authentic user. The phenomenon of Web spoofing or creating misleading Web sites that closely represent real sites in order to extract personal financial data from unwary Web visitors, is common form of online scam that contributes to identify based credit and financial fraud and threatens to undermine consumer confidence in Internet shopping and banking. The FBI to spoofing as the “the hottest, and most troubling, new scam on the Internet contributing to the rise in identity theft, credit card fraud, and other Internet fraud.” Approximately thirty such hoax attack sites are detected each day, even as many more go undetected.
Replay attacks is when the attacker attempts a capture packets on its way from one host to another, and then replay them to a targeted host in an attempt to mimic a legitimate user or system. The replay attack is easy because it is not difficult to capture the commands to be replayed. A user on a network can run a sniffer program and capture all packets that travel over the network. Replay attack looks for systems with weak a...

...es and disadvantages of both symmetric and asymmetric cryptography are:
Symmetric advantages
• Use password verification to prove the receivers identity
• Encrypted data can be transferred on the link even if there is a chance that the information will be intercepted. There is no key transmitted with the information, the probability of data being decrypted is unlikely
• Secure
• Fast and easy to implement
Symmetric disadvantages
• Cannot provide digital signatures that cannot be repudiated
• sharing keys
• cause a lot of damage if compromised
• have difficulty with key transportation
Asymmetric advantages
• Scalable and does not require much administration
• Easy for user to use
• Can provide digital signatures that can be repudiated
Symmetric disadvantages
• slower due to longer key length
• complexity of the encryption algorithm used

Privacy and security issues have become one of the top concerns among computer users in today’s market. It has become a game of survival of the fittest in protection of your security. The only true way to defend yourself is knowledge. You should prepare your self against hackers, spammers and potential system crashing viruses and web bugs. Lets focus on how you can protect yourselves from the would be thieves.
Identity theft is a term used for describing criminal that uses individual’s identity without consent. A common crime of identity theft would be identity fraud. Many of the crimes are regularly connected with money-related issues (Reyns, 2013). With technology being commonly used nowadays we are getting more dependent on it for business, financial, medical, and other forms. As a result this became a target for identity thieves as well. The Internet provides us information and accessibility, but information being stored on the Internet eas...
Security is a wide concept, it is a separated subject with its own theories, "which focus on the process of attack and on preventing, detecting and recovering from attacks" (William 1996). Certainly, these processes should be well organized in coping with the complex system issues. A coherent approach should be taken, which builds on established security standards, procedu...
Identity theft is one of the fastest-growing crimes in both the US and abroad. The Federal Trade Commission (FTC) estimates that identity theft costs consumers as much as $50 billion annually and that this number will likely keep growing (Finklea, 2010, p. 1). Additionally, the FTC receives in excess 250,000 consumer complaints of identity theft each year and this is believed to be only a fraction of the total number of victims (Finklea, 2010, p. 9). There are several types and methods of identity theft and these methods continue to increase as technology becomes increasingly sophisticated. Understanding the types and methods of identity theft can reduce potential victimization.
This research paper is a comprehensive look at DoS attacks, including information about their history and development, how to detect them, and what measures should be taken to prevent large amounts of damage.
There are numerous network security devices and tools available to aid in computer network defense, and these tools are often relied upon for protecting against increasingly sophisticated, stealthy, and damaging attacks. When acting alone, the current generation of security devices has an exceedingly difficult time providing an effective defense against such threats, and the situation is particularly grim for targeted or novel attacks.
The ability to conduct warfare through technological methods has increased information security awareness and the need to protect an entities infrastructure. Subsequently, cyber warfare produces increased risk to security practitioners that employ technology and other methods to mitigate risks to information and the various systems that hold or transmit data. A significant risk to information lies in the conduct of electronic commerce, hereinafter called e-commerce. E-commerce is the purchasing or selling of goods and/or services through the internet or other electronic means (Liu, Chen, Huang, & Yang, 2013). In this article, the researcher will discuss cyber warfare risks, present an evaluation on established security measures, identify potential victims of identity theft, and present an examina...
As mentioned before, the focus of this paper is to compare and contrast human error and hacking. Hacking can be defined as exploitations to weaken a computer systems. Thus, creating a breach in information security and is done for many reasons mainly for financial gains and to exposed hiding agenda whereas human error occurs as a result of one of the following reasons: loss of administrative credentials, employee negligence, and third party access just to name a few.
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...
Every day, citizens are constantly losing money and being victimized due to these fraudulent activities. Cyber crime, including fraud, identity theft, stalking, and hacking, is a growing problem that can be prevented by taking the proper precautions. The biggest cases of cyber crimes are cases of fraud. Online fraud comes in many forms. It ranges from viruses that attack computers with the goal of retrieving personal information, to email schemes that lure victims into wiring money to fraudulent sources” (What is “online fraud”).
The factors that pose a threat to information may include inter-connectivity and the wireless applications used in business (Rainer & Turban, 2009, p. 1). There is massive communication of computers following the inter-connectivity and this introduces a lot of challenges in the manning of information security (Rainer & Turban, 2009, p. 1). The massive inter-connectivity has acted as a brooding ground for many attackers and malicious programs. This has brought about the idea of trusted and un-trusted networks that operate outside the business applications (Rainer & Turban, 2009, p. 1). Research has shown that wireless communication is the most risky in terms of information security but yet it is the most effective since it enables employees to access information from any part of the world (Rainer & Turban, 2009, p. 1).
The methods that criminals use to get identity from people are always changing. There are 3 particular categories that these methods can be divided into.The first category is information given away. This method is referred to as the easiest way to steal someones identity. This occurs when people simply just give away information like their address to strangers or when they are not safe online and their personal information can be accessible to anybody.The second category is known as offline methods.This category includes techniques like: dumpster diving, shoulder surfing, wallet or document theft, bogus phone call, skimming, pretexting and business record theft. The third category is refereed to as online methods. This includes ...
Millions of people around the world use computers and the internet every day. We all use it in school, work even at home, computers have made us life easier, it has brought so many benefits to the society but it has also brought some problems and cybercrimes is one of them. “The times have really changed,” said Greg Garcia, the department’s assistant secretary for cyber security and communications. “We’re seeing now phishing, farming, botnets … war dialing and domain server spoofing. And we’re seeing coordinated cyber-attacks against nation states.” (Fowler 5) Cybercrime is one of the most prevalent and most popular rising crimes being committed today. This is criminal activity done using computers and the Internet. There are millions victims around the world everyday who face these problems. Most people become victims of these at one time or another, but there are ways to avoid or deal with cybercrime by protecting yourself appropriately. I also was one of those victims who faced a similar problem. This unfortunate truth forces me to understand that computers and the Internet have made our lives easier in many ways. However, it is unfortunate that people also use these technologies to take advantage of others through identity theft, hacking attempts, and malicious use of software.
Harmful usage of a sniffer is catching password and also capturing special and private information of transactions, like username, credit ID, account, and password, recording sending of email or messages and resuming the information, Some Sniffers have the ability to modify the computer's information also to the extent of even damaging the system. Weakening the security of a network even being successful in gaining higher level authority. With everyday more and different hackers using of packet sniffers, it has become one of the most important tool in the defence of cyber-attacks and cyber-crime. Writted by (2001 – 2014) Colasoft LLC
