Mathematics in Our World Essay Example for Free

Mathematics in Our World Essay This is a type of service offered by financial firms such as credit unions, banks, savings and loans firms. Advantages It enables people to withdraw their money from a federally protected account. While banks vary as regards terms of check accounts, it has another advantage that holders of checking accounts pay debts with personal checks as substitute for cash. Further, holders can use automated teller machine cards or electronic debit cards to make withdrawal or access individual accounts (Marce, 2009). Therefore this will be a choice if the money is needed to be spent on regular basis. This lies in the fact that with $1000, there is no accruing interest on deposited funds. The other disadvantage is that a penalty is applied if one falls below a minimum. One may also be charged fee depending on the policy of the bank. SECTION B Money market account is similar to regular savings account. It is a form of savings offered by credit union (Baztelsmit, 2007). The difference lies in the fact that on the contrary, they give opportunity for only 3-6 withdrawal in a month and they also offer great interest rates. Its advantage over checking account is that interest is earned on funds deposited. Also, one can write up to 3 checks in a month in money market account. Disadvantages Their minimum balance requirements are higher and can be up to $1500 $2500. The other disadvantage lies in that there is no guarantee return. The expected amount to be earned is not guaranteed and possibility of losing money in such account exists in rare case (Marce, 2009). SECTION C The Passbook This is good especially for investors who don’t need monthly statement and transact infrequently. This form of investment means is a midway option used by some individuals. Advantages Passbooks are updated with information from time to time. It is a liquid account in that fund is readily available and accessible to holders just like in checking account, although, unlike checking accounts, interest here is nominal and small (Baztelsmit, 2007). Disadvantage Deposited money could earn a higher return. SECTION D Certificate of Deposit This is a financial product usually offered to investors by credit unions, banks and thrift institutions. Advantage Banks offer a fixed interest rate having agreed to lock certain funds for a set period of time. Interest rate also increases with increasing period of time the money is locked which varies and can be between a month and ten years. Another advantage is that CDs are insured by FDIC for banks or by NCGA for credit unions and are almost risk-free (Marce, 2009). Disadvantage A major disadvantage of CD is that it’s not a good option if the money to be invested will be needed anytime as withdrawal of money before maturity date attracts heavy penalty. The type of account I have chosen and why I have chosen that account Considering the fact that I have $1000 to invest, the best option for me to invest would probably be the Certificate of Deposits. My reason for this is that I have committed the amount for long term investment and do not need to withdraw funds constantly. It gives me the best and highest return on my investment over the shortest possible period of time (Baztelsmit, 2007). If I had needed to withdraw money frequently, money market would have been my choice account. Furthermore, certain bank allow further investment to be made on this principal fund over time and in this way are a mirror image of savings account and so allows me to deposit additional money.

The Most Affordable Vacation for a College Student :: Research Papers Travel Essays

The Most Affordable Vacation for a College Student In December, my boyfriend is heading to Iraq to fight for his country and for all of us in the United States. We have decided together, that upon his arrival home, we will reward ourselves with a vacation. The question we both had though was where should we take this vacation? We both believe that next year will be a really hard time for both of us, being separated for at least a year. I have decided to take the initiative to research our possible destinations with the most affordable rates. Together, we narrowed our choices down and decided to vacation in Hawaii or an island in the Bahamas. So with this information, I decided to research the locations of our choice to help us finalize our decision. The first thing I did was decide to research Maui, Hawaii. I have heard many great things about Hawaii, and thought that this would make a great report. I gathered information online, comparing airline prices, hotel prices and also attractions in Maui. To gather even more information, I traveled to the travel agency in which I belong to, AAA’s where I received a lot of great catalogs on Maui. I did not know definitely where I was going with this project, but decided to research the information. I discovered that Hawaii was just a little bit out of a college student’s budget, even if saving for a year. So I thought I would compare and research the Bahamas, our other choice. I once again started online, researching much like I did with Hawaii. This time when I traveled to AAA’s, I talked to Sharon Biggs, a very helpful travel agent. She gave me brochures explaining about the two islands in the Bahamas. She told me that because I was under the age of 21, the better vacation choice was the Bahamas over Hawaii. When we travel on our vacation, my boyfriend will be over 21, but I will not. The age of 21 meaning, I could not drink, but he could. My final step was to call my aunt and uncle, who have traveled to the Bahamas, Mexico, Bermuda, and taken several cruises. I wanted to receive their insight on the location that I had chosen. They were very reliable in the sense that they travel often and I have not been to all the places that they have been to.

Host based Intrusion Prevention

Intrusion Detection Systems (IDSs) recognize the presence of malicious code within traffic that flows through the holes punched into the firewall, our first layer of defense. Though, the word â€Å"intrusion detection† is a bit of a misnomer.Richard Kemmerer and Giovanni Vigna of the University Of California, Santa Barbara, elucidate in an article in the IEEE Security and Privacy magazine: â€Å"Intrusion detection systems do not detect intrusions at all–they only identify evidence of intrusion, either while in progress or after the fact.† (Edwin E. Mier, David C. Mier, 2004)An IDS recognizes security threats by detecting scans, probes and attacks, however does not block these patterns; it only reports that they took place. Yet, IDS logged data is invaluable as proof for forensics and incident handling. IDSs as well detect internal attacks, which are not seen by the firewall, and they help in firewall audits.IDSs can be divided into 2 main categories, footed on t he IDS alarm triggering mechanism: anomaly detection-based IDS and misuse detection-based IDS.Anomaly detection based IDSs report deviations from â€Å"normal† or expected behavior. Behavior other than â€Å"normal† is measured an attack and is flagged and recorded. Anomaly detection is as well referred to as profile-based detection. The profile describes a baseline for normal user tasks, and the quality of these user profiles directly has an effect on the detection capability of the IDS. Techniques for constructing user profiles comprise: (Nong Ye, 2003).Rule-based approach–Normal user behavior is characterized by creating rules, however analyzing normal traffic is a complicated task. A related approach is protocol anomaly detection.Neural networks–These systems are trained by presenting them with a large amount of data, together with rules regarding data relationships. They then find out if traffic is normal or not; abnormal traffic raises an alarm.Stat istical approach–Activity profiles describe the behavior of system or user traffic. Any deviation from normal triggers an alarm.The advantage of anomaly detection is that it can identify previously unknown attacks and insider attacks, without the need for â€Å"signatures†Ã¢â‚¬â€œ that is., predefined attack profiles.One more benefit of anomaly detection is that it's impossible for the attacker to know what activity causes an alarm, thus they cannot assume that any particular action will go undetected.The disadvantage of anomaly detection is that it produces a large number of â€Å"false positives†Ã¢â‚¬â€œ that is., alerts that are produced by legitimate activity. In addition, besides being complicated as well as hard to understand, building and updating profiles as well need a lot of work.The other most important approach, misuse-detection based IDS (also called signature-based IDS), triggers an alarm when a match is found to a â€Å"fingerprint†-a signa ture contained in a signature database. These â€Å"fingerprints† are footed on a set of rules that match typical patterns of exploits used by attackers. As there is a known database of exploits, there are few false positives.The disadvantage is that misuse-detection IDSs can merely detect already-known attacks. Besides, the â€Å"fingerprints† database needs to be incessantly updated to keep up with new attacks. The majority IDS products in the market at present use misuse detection.

The WHO states that 1 out of every 10 rivers is badly polluted, which totals up to about 473 rivers in Malaysia which have decreasing water quality standards. In response to this, the legislative approach taken in Malaysia was with the 1974 Environmental Quality Act, which states that a report on various â€Å"prescribed† activities must be shown to see how the water has been affected by these activities. Among the endorsed exercises or then again extends that can cause water contamination incorporate airplane terminal, lodging, industry, mining, oil, control age, resort and recreational advancement, and waste treatment and transfer offices. For other activities, assessment would likewise be completed in order to evaluate the limit of the territory to get extra contamination stack and the necessity for squander transfer. The Environmental Quality (Sewage and Industrial Effluents) Regulations 1979 additionally require that composed consent be acquired before the development of any building or completing any work that may result in another wellspring of profluent or release. Also, there have been controls for different industries that have been put into action to reduce water pollution. For example, agro-based industries were â€Å"forced to install effective wastewater treatment systems instead of paying the prohibitive effluent-related or pollution fees imposed under the licensing requirements that came into force since 1977. The organic pollutant load dumped into rivers has been greatly reduced by more than 90 percent of the total load generated.†
