DoS/DDoS Prevention

This document details guidelines that can be implemented to the school to prevent the recent DDoS attack the school experienced. These guidelines are by no means any requirement, however each will grant an additional layer of security for the current networks and services in production.

Implement Policies and procedures

An Acceptable Use Policy is a policy that defines what type of actions are allowed to be performed on the systems and network to which the policy applies. For the school, an Acceptable Use Policy may state that users of the computers and network must be performing functions related to the school such as homework, administration, research, etc.

In addition to defining what is allowed, the Acceptable Use Policy should also specify what actions will be taken when a user or individual violates the policy. The acceptable use policy should be made accessible to every user. One method to do this would be to display the policy when a user logs in or direct them to where they can read the document. (Glenn, 2003.)

Develop Incident Response Procedures

The incident response procedures should identify the following: ← Define who the respondents are and what each individual's responsibility is ← Specify what data is to be collected and what actions are expected ◦ This would include gathering information on the attacker and a clearly defined resolution path for the team to return systems to a pre-attack state ← Details to when the team should respond ◦ Different systems should be given different priorities depending on their importance. ← How should the team escalate issues when a critical decision is needed to be made? ◦ One method to handle this would be to include a variety of individuals on the team including a key decision maker. (Glenn, 2003.)

Patch Management

All systems has an operating system running on them and vendors for those systems continually release patches when security holes are discovered or new features are implemented. Despite their importance, they can break existing resources or open up new undiscovered security flaws.

It is for these reasons that it is as important to fully test new system patches as it is to get them applied to systems. If possible, patch testing can be done in a virtual environment drastically reducing the number of test machines needed.

A detailed summary of patch testing should be completed and well documented before installing the patches. It may also be beneficial for the patch to be given a second look by another individual before installation. (Glenn, 2003.)
Implement an Audit Schedule

Information systems can and should be audited on a regular basis to check for irregularities, improper configurations, and allow for a time when individuals can critically think about added recommendations that can be implemented.

Information security audits include: ← Reviewing firewall and router ACLs ← Port scanning of firewalls, routers, servers, and other machines ← Performing vulnerability assessments of critical services, computers, and network devices ← Checking users and other access controls ← Analyzing installed software

In the recent attack, if regular audits were performed it is possible that the rogue software could have been detected as well as any network anomalies presented by the software. (Glenn, 2003.)

Implement an Intrusion Detection/Prevention System

An IDS or IPS allows for malicious or strange traffic on the network to be identified and either notify an administrator and even create a firewall rule to put a stop to the traffic.

In the school's case, an IDS or IPS should be placed in front of the network resources of most value if not all network resources. If an IDS or IPS had been in place it would have been possible for an administrator to have been notified the moment the DDoS began. This would facilitate a much quicker response than without the system at all.

In addition, it is possible that other types of traffic could have been detected before the DDoS occurred that would have signaled that some machines may be infected with a foreign software. This would have allowed for the intervention before any malicious act could be performed. (Glenn, 2003.)

Row hard enough that your arms fill with cramps and your hair turns white with stress, row until your back pains with your incessant, consistent, ritualistically morbid and mentally dangerous norms. But, row long enough and you will become tired of this ridiculous method of transportation and long for something better, a propellor perhaps to do the rowing for you? And as you sit peacefully behind the wheel of your new vessel, somewhere inside of your newly relaxed mind, ideas emerge, that incredible longing for the different.

Why, even though the idea in itself is morally wrong, do we accept ourselves as part of a Capitalist union? Or even, why we......

Tragedy of Denial

...Tragedy of Denial Arthur Miller is considered to be one of the greatest play writers of his times. After many years the themes of his plays can still be compared to our every day life. Miller has written his plays filled with drama, tragedy and leaving the reader feeling the emotion of his characters. Miller has used common themes that can be traced through some of his plays; the theme of family and the extent an individual will go to for their family. In three of his plays, Miller demonstrates tragedy wrapped within denial. The three families portrayed in Millers plays, All My Sons, Death of a Salesman, and A View From The Bridge are families that are consumed with denial to cover up and protect against their own guilt and selfish needs. Each of these families have characters who display such strong denial believing they are doing what is best for their family. However, when taking a closer look, what is reviled is failure and justifications to protect what is best for them selves. In All My Sons by Arthur Miller, the characters forming the Keller family are living in the 1940’s, a time where financial stability seemed out of reach. Joe Keller who is a father, husband, and business owner, is one of the main characters in this play. Joe is able to provide his family with the financial stability he has wanted but at a high cost. With one bad decision, Joe committed a crime that he never thought would affect his family directly. Joe allowed the defective airplane......

League of Denial Report

...The League of Denial is an exposé on the NFL’s handling of medical research on concussions, specifically Chronic Traumatic Encephalopathy (CTE), in the late 1990s and early 2000s. The documentary, put together by investigative reporters Mark Fanairu-Wada and Steve Fanairu, details the different suppression and negligence of the research being done on the effects of concussive hits in football. One of the most telling storylines in the documentary is the one that revolves around Dr. Bennet Omalu and Mike Webster. Mike Webster was a Hall of Famer for the Pittsburgh Steelers during the 1970s. After his career was over, he began to experience a personality change. He was losing his memory, and according to his wife, he started to garner anger issues. Webster died at the age of 50. After Webster’s death, Dr. Bennet Omalu performed an autopsy on him. Omalu examined Webster’s brain, and found it to be severely atrophied. Omalu then began a quest to find the answers on why Webster’s brain was so atrophied. Upon further investigation, Omalu found that this was a recurring disease in athletes who are involved in contact sports (football, wrestling, hockey, etc.). This was the inception of CTE, which is only diagnosable in an autopsy post-mortem. Omalu then brought his evidence to the NFL, which gave him the figurative cold shoulder. They would not take Omalu seriously, and took steps to discredit him. After a long fight, Omalu took a break in trying to convince the......

It Services

...Five Services to Help Grow Your IT Services Business in 2013 — and Beyond Introduction 2013 is a year of great opportunity for Managed Service Providers (MSPs). As reported in the Wall Street Journal, IT spending by businesses with fewer than 500 employees is expected to grow by $4 billion to a total of $27.2 billion in 2015.1 The good news does not end there for MSPs. According to a recent study, 89% of MSP clients are “very” or “mostly” satisfied with their providers.2 In fact, a significant majority of clients reported that they intend to increase their IT spending in the next two years. Now is the time to position your company for growth by preparing to meet new and evolving client needs. 3 If you are an MSP seeking to grow or maintain your business in 2013 and beyond, market conditions are such that there will be many opportunities to acquire new clients or expand on the services provided to your existing clients. Your challenge is in differentiating your business from thousands of other providers in the marketplace who share your ambitions. A recent Wall Street Journal article revealed that there are now over 300,000 independent IT consultants and 114,000 small IT services companies providing support to small and mid-sized businesses (SMB).4 There may also be new competitors on the horizon as technology retailers such as Staples, Apple, and Best Buy eye the SMB marketplace and work to develop offerings that will compete with the traditional......

Case Analysis: the Ipremier Company - Denial of Service Attack

...Case Analysis: The iPremier Company - Denial of Service Attack Matthew M. Lambert Introduction: The e-commerce landscape is littered with the remnants of companies that didn’t survive the meteoric dot com boom and subsequent bust that began in the late 1990s. iPremiere Company, however, was the exception to the rule. Created by two college students in 1996, the web-based company had solidified its business position as a top online retailer of high-end, luxury goods with $32 million in sales and $2.1 million in profit for 2006. Consumers bought directly from iPremiere using credit cards, which were then stored on the company’s servers. In 2007, computer hackers launched a Denial of Service (DoS) attack on iPremiere’s website, temporarily shutting down the website and taunting iPremiere with emails. The possibility of hackers breaching its security firewall is extremely troubling because it puts customer financial information at risk and the loss of this public trust would be disastrous for iPremiere. The purpose of this paper is to assess why iPremiere was vulnerable to attack, examine their approach to both IT risk management and crisis communications and offer recommendations that foster customer trust and company profitability in the future. SWOT Analysis A brief SWOT analysis shows that iPremier’s strengths include good placement in the e-commerce marketplace and a highly experienced and productive team of managers and software developers dedicated to meeting......

Concussion: a condition resulting from the stunning, damaging, or shattering effects of a hard blow; especially: a jarring injury of the brain resulting in disturbance of cerebral function and sometimes marked by permanent damage ( Concussions have become more prevalent in the National Football League as awareness has risen. There are numerous cases of CTE that have resulted in permanent damage or death over the course of the last 15 years. The reality behind concussions is that there will never be a total solution to the issue, in contact sports the danger will always be there. We must continue to raise awareness and develop protective equipment to minimize the risk. Concussions are one of the leading causes of CTE among all professional athletes toady. Mike Webster retired in 1991 from the NFL and the Pittsburg Steelers after 17 years in the “pit” and made an attempt at a normal life, a short time into this journey it became apparent that “Iron......

Services’s not matched to my order because when I tasted it, it’s not Java Chip that I ordered. I checked the name written on the cup to make sure if my name was placed there but my name was there. So, what I did was I went to the counter and complained about my order. I told them that they gave me a wrong order because it’s not really my order. After I complained, they apologized and said sorry to me. And what they did to recover their wrong service was that they gave me my order Java Chip with venti size which is the biggest size of their frappe. Also they gave additional product which was doughnut just to recover their wrong service. For me its passable, as long as they will recover what they did wrong to their customers and as long as they will satisfy their customers. Because there are some customers that are not easily satisfy with the replacement. But for me, it okay. Their strategies on how they will redesign their service are gradual. They will not let others customers know what happened. They will immediately do actions in that particular service. 2. Ministop I remembered when I bought a fried chicken meal at Ministop.

As name suggests Denial of Service aka DoS, it’s main objective is to make the system to deny the legitimate service requests.
