Risks of a Dos Attack

Despite the presence of network security devices such as firewalls and other security appliances, today's corporate networks are still vulnerable to both internal and external attacks by hackers intent on creating havoc. By proactively

The trusted computing base (TCB) internal network in the Global Finance, Inc. Network Diagram hosts the company’s mission critical systems without which the company’s operations and financial situation would suffer. The Oracle database and email systems are among the most intensively used application servers in the company. As we know, GFI cannot afford system outages because its cash flow and financial systems heavily depend on the network stability. GFI has experienced DOS network attacks twice this year and its Oracle database and email servers had been down for a week. The recovery process required GFI to use $25,000 to restore its operations back to normal. GFI estimated the loss from these network attacks at more than $100,000 including lost customer confidence.

This presentation discusses an incident known as a denial of service (DoS) as well as an intrusion of the clinic’s network systems. A denial of service (DoS) attack is designed to shut down services which a business needs to operate. This incident caused widespread slowness and outages to internet services and affected the clinic’s capability to properly treat its patients. In this presentation, the incident is examined. The processes to detect, analyze, contain, eradicate and recover from the incident are the focus of the presentation. Once the incident investigation was complete, special consideration was made as to what was learned and how clinic staff can help protect the clinic’s ability to properly serve its patients.

On January 2014, Michaels an art and craft retailer and its subsidiary Aaron Brothers, revealed that costumer information database consist of payment card number and expiration date been compromised. Costumer using credit or debit card at Michaels in between May 8, 2013 to Jan 27, 2014 compromised 2.6 million cards and at Aaron Brothers in between June 26, 1013 to Feb 27, 2014 been compromised 400,000 cards. The company committed to work with other parties to improve security of payment card transaction for all consumers.

It is not clear in the article if iPremier did any risk assessment, and if they did, they didn’t anticipate that they could be victims of a DDoS attack. iPremier should have used a Contingency Planning standard like NIST SP 800-34 to identify risks and develop policies and procedures to deal with attacks like the one they faced. If they had these, they could have responded in a more orderly and affectively fashion and they could have alternatives to overcome the negative impact

Further details about this topic will be discussed later in this research paper including the vulnerabilities attacks that are involved in Critical Infrastructure. Potential risk vulnerabilities that are used to make offense an attack are identified and risk and impact analysis on these potential risks to prevent from further attacks are also identified.

Incident response begins with prevention and security awareness (figure 1). In the case of malware attacks such as viruses, worms or Trojan horses, defense-in-depth plays a large role in the defense and early detection of potential threats to information systems connected to the internet. Personnel utilizing these assets also play a large role in defending and protecting these assets. Authorized users should be aware of all policies and procedures pertaining to the proper use of all networks, applications, and systems within the organization. The

A DoS Attack, or Denial-of-Service attack, is an attack that that fill a network with lots of useless traffic. Many DoS attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the TCP/IP protocols. A couple of the most recent DoS attacks have been directed to Capitol One and SunTrust Banks. In October Capital One and SunTrust were attacked by this Denial-of-Service. Capital One’s website was inaccessible for 8 hours because the network was just filled with useless traffic. In the next couple of days SunTrust bank suffered performance issues.

When discussing the iPremier denial of service attack, there needs to be some background in order to fully understand the position the company was in at the time. Firstly, a denial of service attack is an attempt to make a piece of hardware like a machine or network resource unavailable to its intended users. This attack is performed by sending out a flood of information packets that causes congestion within the networks resources, deducing them unavailable. Denial of service attacks are conducted with malicious attempt as displayed by the iPremier case. The iPremier company was founded in 1990s by two students in Seattle, Washington. The company specialized in selling web-based commerce, such as luxury products, rare merchandise, and vintage goods over the internet. iPremier’s competitive advantage was their flexible return policies which allowed the customer to thoroughly check out the product and make a decision to keep the product or return it. The majority of iPremier customers are high end and credit limits are not a problem, which also adds to the competitive advantage of utilizing their entire customer base. They were one of the few companies in the 90s that were successful in this business sector and by the end of the decade the company saw sales as high as $32 million and a profit of $2.1 million. Sales had increased by 50% during the last three years of the decade and they were in an upward trend. iPremier’s stock nearly tripled after the company’s initial public

A Denial of Service (DoS) attack on the corporate IT system at IVK Corporation. (Adapted from the book The Adventures of an IT Leader, 2009, Harvard Business School Publishing). After reading the case description, answer the questions that follow.

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.

iPremier’s procedures were absolutely deficient. They had an outdated emergency manual that employees couldn’t find, and almost couldn’t access the data center. Additional measures they could have implemented long before the attack include revising the emergency procedure and making sure all employees know how to follow it. 3. Now the attack has ended, what can the iPremier Company do to prepare for another such attack?

Internet security is not only a continuing problem, but an increasing one. Yet, many companies do not have adequate internet security measures in place. To help businesses thwart cyber criminals operating over the internet, several steps are recommended. First, before deciding to use the internet for business purposes, organizations should articulate how they intend to use the internet (e.g., e-commerce; marketing web site; communication with business partners, customers, suppliers). Once this information is articulated, the company should next assess what risks are associated with each of the uses. Risks are the quantifiable likelihood that a financial investment will result in loss for the investor. A high risk investment is associated with both a higher probability of loss and a possibility of greater return on investment. Risk assessment is the process of determining the potential loss and probability of loss of the organization’s objectives.

The purpose of this paper is to describe, model, and talk about Denial of Service (DoS) attacks and specifically as the DoS attack that occurred at The iPremier Company on January 12, 2007. Especially nowadays, there are so many various online security threats that are occurring and that have occurred. DoS attacks have the most damaging and devastating effects. This puts an extreme amount of pressure on security experts to have strong and effective techniques put in place to defend against these attacks. These particular cyber attacks can be implemented quite diversely with a variety of tools, codes, and proper procedures. There really is no true solution for DoS attacks, which have been tormenting websites for approximately a decade. iPremier was one of the most
