DDoS attack -denial-of-service attack

DDoS attack -denial-of-service attack


This article was written because report that many website even facebook page was attack by DDoS recently.

To make clear what is DDoS attack here is the nice definitaion from wikipedia.

A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers. The term is generally used with regards to computer networks, but is not limited to this field; for example, it is also used in reference to CPU resource management.

One common method of attack involves saturating the target machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.

Denial-of-service attacks are considered violations of the IAB's Internet proper use policy, and also violate the acceptable use policies of virtually all Internet service providers. They also commonly constitute violations of the laws of individual nations.

Ping Flood

The most basic of attacks is the ping flood attack. It relies on the ICMP echo command, more popularly known as ping . In legitimate situations the ping command is used by network administrators to test connectivity between two computers. In the ping flood attack, it is used to flood large amounts of data packets to the victim’s computer in an attempt to overload it. You can see an example of the ping flood attack below.

FOREX (Foreign Exchange Market)

FOREX (Foreign Exchange Market)
The foreign exchange market is also known as FX or it is also found to be referred to as the FOREX. All three of these have the same meaning, which is the trade of trading between different companies, banks, businesses, and governments that are located in different countries. The financial market is one that is always changing leaving transactions required to be completed through brokers, and banks. Many scams have been emerging in the FOREX business, as foreign companies and people are setting up online to take advantage of people who don't realize that foreign trade must take place through a broker or a company with direct participation involved in foreign exchanges.

Cash, stocks, and currency is traded through the foreign exchange markets. The FOREX market will be present and exist when one currency is traded for another. Think about a trip you may take to a foreign country. Where are you going to be able to 'trade your money' for the value of the money that is in that other country? This is FOREX trading basis, and it is not available in all banks, and it is not available in all financial centers. FOREX is a specialized trading circumstance.

Small business and individuals often times looking to make big money, are the victims of scams when it comes to learning about FOREX and the foreign trade markets. As FOREX is seen as how to make a quick buck or two, people don't question their participation in such an event, but if you are not investing money through a broker in the FOREX market, you could easily end up losing everything that you have invested in the transaction.

Scams to be wary of
A FOREX scam is one that involves trading but will turn out to be a fraud; you have no chance of getting your money back once you have invested it. If you were to invest money with a company stating they are involved in FOREX trading you want read closely to learn if they are permitted to do business in your country. Many companies are not permitted in the FOREX market, as they have defrauded investors before.

In the last five years, with the help of the Internet, FOREX trading and the awareness of FOREX trading has become all the rage. Banks are the number one source for FOREX trading to take place, where a trained and licensed broker is going to complete transactions and requirements you set forth. Commissions are paid on the transaction and this is the usual.

Another type of scam that is prevalent in the FOREX markets is software that will aid you in making trades, in learning about the foreign markets and in practicing so you can prepare yourself for following and making trades. You want to be able to rely on a program or software that is really going to make a difference. Consult with your financial broker or your bank to learn more about FOREX trading, the FX markets and how you can avoid being the victim while investing in these markets.
