The Effects Of Network Attacks On The Internet

Since the onset of the first packet switching event that many believe to be beginning of the internet, no other technology besides the printing press has ever transformed the ability to deliver information. Although the internet is used by a large percentage of the civilized world, few Americans realize how vital cyberspace is to our national infrastructure. Today, we are faced with even more threats although it has been a recognized problem since 2009, when President Barrack Obama said “The cyber threat is one of the most serious economic and national security challenges we face as a nation. It’s also clear that we’re not as prepared as we should be, as a government or as a country (Obama, 2009).” Every industry that operates in the United States is dependent on the internet for some aspect of their business. Commerce, transportation, financial institutions, military, as well as industrial control systems are all interconnected. This interconnectedness has created vulnerabilities within their infrastructure that have increasingly become targets of terrorists, script kiddies, foreign governments and hackers of all types.

Most ISIS practice customs from the 7th century, but the methods they use to fight a war are 21st century techniques. ISIS have an advanced computer network that uses social media to attract terrorists worldwide to help them attack countries like the United States. Many countries have been victims of cyber attacks but may not realize it until long after the security breach occurred.

This Denial of Service (DoS) intrusion event started unfolding as the clinic’s users of the internet started to experience such slowness in connecting to systems that they were unable to perform their jobs. This lack of

Cyber security policy is largely dominated by two separate but similar incidents, cyber terrorism and state sponsored events. A cyber terrorist attack may be defined as a computer based attack, the purpose of which is to cause enough destruction that it intimidates a government into compliance for political purposes (XX1). State sponsored attacks, by contrast, is the intentional use of cyberspace by governments to illegally obtain classified information from another state. Such information may be used for malicious purposes, such as assessing an enemy state's weaknesses (XX). As mentioned in Chapter 3, Canada's cyber security agencies have existed since the early days of the Cold War. However, the maintenance of Canada's

Explains what a botnet is, how it is created, used and the amount or types of data that can be collected over time. The ability to track or monitor many of these botnets by antivirus software is reported to be a very low percentage of known botnets. One of the basic principles is almost a “throw everything at it and see what sticks” mentality in that developers will employ a botnet through embedding it in a quasi-convincing spam message and hoping the reader is dumb enough to click on the link (Mittleman 67.)

The Internet has changed and advanced modern society in unimaginable ways since its conception. Banks, transportation, entertainment, and even power and sewer systems are now controlled and operated through the Internet. This has allowed major improvements to society as a whole. Power is now delivered more reliably, many people can now access their banking information remotely from their phones, shopping can be done completely from the comforts of the home, as well as many other amazing things. All of these things are convenient and helpful, but have exposed American citizens and infrastructure to the new threat of cyber based attacks. These attacks can be directed at American institutions or to the general population. I believe that the threat

The exponential increase use of the Internet to communicate, conduct business transactions, access personal banking, healthcare, education at confront of being anywhere has become an everyday lifestyle for many people around the globe. This reliance on computers, laptops, devices and other Internet of Things to access the Internet means, organizations, businesses and the government have also seen an increase occurrence of sophisticated attacks.

Once your computer is among the living dead, it becomes a part of a botnet, or a network of other zombie computers” (par. 2). Botnets are designed in order to gather personal information including passwords, credit card details, social security numbers, addresses, and telephone numbers. These data may then be used for crimes including identity theft, frauds, spamming, and other malware distribution. Drozhzhin also stated, “Once a computer is a bot, it begins accepting commands from a centralized command server” (par. 4). As soon as the device become part of a botnet, they can receive commands to launch attacks on other devices, websites, and networks. This is important to know because in order to launch an effective Distributed Denial of Service (DDoS) attack, a large number of bots are required. The attack is more effective because the more “zombies” recruited, the easier and faster it is for the attacker to constantly transmit requests and malwares to other computers, thus crashing the site. Additionally, multiple bots sending requests from different locations makes the attack tremendously more difficult for antivirus and antispyware to distinguish a malicious request from an actual consumer’s request. The worst part is, it is almost nearly impossible to

Adam Segal’s “The Hacked World Order” reveals many prevalent issues in today’s technologically centered society. Starting at Year Zero, June 2012 to June 2013, the battle over cyberspace witnessed world-changing cyberattacks. This was accomplished due to the fact that nearly 75% of the world’s population has easy access to a mobile phone, and the Internet connects nearly 40% of the total human population, which is nearly 2.7 billion people. With that being said, cyberattacks are becoming a more realistic form of terror.

As the term was used more frequently, I started to learn that this concept was real and frankly frightening. A DDOS attack meant a distributed denial of service attack, causing one’s Minecraft character to disconnect from the server and drop everything they had for the other players to steal. The fact that someone could use the machine I do homework on to impact another person’s computer was fascinating to me. I asked about the DDOS attack and was told that one can “resolve” someone’s “IP” from their Skype name and use a “botnet” to take out their Wi-Fi. I figured this idea was too complicated to be true, so I ignored it and continued to play. Until one day I conflicted with the wrong person and spent the next 30 minutes without Wi-Fi. After that, I spent many hours researching how this was possible. I watched videos, read blogs, and joined many forums, trying to get a grasp on the topic. My goal: to never have my system compromised again. Through all my hard work, I became famous on the Minecraft server because no matter how agitated people became, they were not able to find my IP. I made it my business to help every player have the same protection, soon helping more than 20 people. From that point on, cyber-security became my passion. I am still blown away by everything a computer can do.

A Denial-of-Service (DoS) attack is a general name for any kind of attack against data availability. In the Web application world, a DoS attack aims to “take down” the site in order to make it inaccessible to its users. This may cause some serious financial damage to the site, both directly and indirectly by damaging its reputation.

A cyber-criminal can create a denial-of-service attack by sending spam emails to a network. The spam emails can be sent to an email account supplied by an employer or a free email account offered by Hotmail and Yahoo. With each email account, the user is assigned a specific quota that specifies the amount of space the account can have at a given time. If the cyber-criminal sends large amounts of spam messages to a user’s email account then the quota will be exceeded and prevent the user from receiving legitimate messages.

Denial of Service (DoS) attack is a very common cyber menace that renders websites and other online means inaccessible to intended users. There are various types of DoS threats and nearly all directly target the core server structure. Others abuse weaknesses in application and communication proprieties. DoS is also used as a cover-up for other wicked actions, and to take down security applications like web firewalls. A prosperous DoS attack is very obvious and impacts the entire online user base.

By the year of 2016, investments in online security are expected to reach $86bn (Contu et al, 2012). Although this might seem a large sum of money, it is considered necessary since there is an increase in online risks from all over the world. Professional hackers develop malware on a global scale and on a 24/7 basis. Hackers have five objectives when spreading malware over the Internet: to infect/distribute, to steal, to persist, to control and for intelligence (Morris, 2010).

The internet is a medium that is becoming progressively important as it makes information available in a quick and easy manner. It has transformed communications and acts as a global network that allows people to communicate and interact without being limited by time, boarders and distance. However, the infrastructure is vulnerable to hackers who use the system to commit cyber crime. To accomplish this, they make use of innovative stealth techniques for their malicious purposes in the internet.
