Out of the different types of trading activities taking place through the internet, oil commodity trading is very costly. This is because all oil commodity trades take place only through highly secured data lines. The other aspect is that the candidates involved in the oil commodity trade are wealthy people. Not only that, the volume of business is in the order of millions of dollars.


The internet technology or the internet itself revolves around large dedicated servers located at strategic geographical locations around the world. Ensuring client-server security is a tough task. The data transmitted and received must reach the destination safely and at a faster pace. So how to ensure that data transfer is secure?


Primarily, the client will encounter client-server security, which means an authorization is needed to 'access' a broker's website. The server checks the order of security. As you enter the intranet or any private network, you are asked for a firewall id and related password. Once you have entered the intranet, the client-server security and database securities come into play. The 'firewall id' is different from the user's 'user access id'. The 'firewall id' is the address that is clarified when packets are entering or leaving the firewall and is provided by the system. The 'user access id' can be one or a combination of the following:
• User id
• First level password (private code)
• Automatic expiry of passwords at the end of a reasonable duration
• Reinitialize access on entering fresh passwords
• Microprocessor based SMART cards
• Dynamic password (secure ID tokens)
• Second level password (personal information, e.g. village name, birth date etc)


Only when the user id and password matches that preset in the server, can a trader get access to the trading system. To ensure greater security, a customer must change his password frequently.

Hi,

Play Mahjong Solitaire

Match pairs of tiles where each tile has at least one side free and no other tiles on top.
Remove matching tile pairs by clicking on each tile in the pair. Use up to 5 reshuffles.

The object in Mahjong is to compete for the top score against other players by clearing the playing area of tiles.
