• As firewall, a proxy protects the local network from outside access.
• As IP-addresses multiplexer, a proxy allows to connect a number of computers to Internet when having only one IP-address.
• Proxy servers can be used (to some extent) to anonymize web surfing.
• Specialized proxy servers can filter out unwanted content, such as ads or ‘unsuitable’ material.
• Proxy servers can afford some protection against hacking attacks.

• Anonymizers are services that help make your own web surfing anonymous.
• The first anonymizer developed was Anonymizer.com, created in 1997 by Lance Cottrell.
• An anonymizer removes all the identifying information from a user’s computers while the user surfs the Internet, thereby ensuring the privacy of the user.

• A denial of service attack (DOS) is an attack through which a person can render a system unusable or significantly slow down the system for legitimate users by overloading the resources, so that no one can access it.
• If an attacker is unable to gain access to a machine, the attacker most probably will just crash the machine to accomplish a denial of service attack.

• bandwidth attacks,
• protocol attacks, and
• logic attacks
  

• An attacker launches the attack using several machines. In this case, an attacker breaks into several machines, or coordinates with several zombies to launch an attack against a target or network at the same time.
• This makes it difficult to detect because attacks originate from several IP addresses.
• If a single IP address is attacking a company, it can block that address at its firewall. If it is 30000 this is extremely difficult.

The term Internet Scam or Internet Fraud refers to any type of fraud scheme that uses one or more online services to conduct fraudulent activities. Internet fraud can take place on computer programs such as chat rooms, e-mail, message boards, or Web sites. In this post I will discuss about some of the commonly conducted scams and frauds across the Internet.

1. Phishing Scam

2. Nigerian Scams

• They may claim that political climate or legal issues preclude them from accessing funds in a foreign bank account
• They may claim that the person is a minor and hence needs your help to access the funds
• They may claim that your last name is the same as that of the deceased person who owned the account and suggest that you act as the Next of Kin of this person in order to gain access to the funds

3. Lottery Scams

4. Other General Scams and Frauds

1. Promise you money, jobs or prizes
2. Ask you to provide sensitive personal information
3. Ask you to follow a link to a website and log on to an account.
4. Propose lucrative business deals

• All these scam emails never address you by your name. In turn they commonly address you something like “Dear User” or “Dear Customer” etc. This is a clear indication that the email is a fraudulent one
• When you observe the email header you may notice in the “TO:” Field that, the same email is forwarded to a large group of people or the “TO:” field appears blank. So this confirms that the email was not intended particularly for you. It was forwarded for a large group of people and you are one among them

I was searching a better way of tweeting without enterting tweeter.com for sending tweets and after a long study i found a solution for the question from search.twitter.com itself !!

There are some useful secret codes to get system information, such as IMEI and software version. This codes taken from Nokia Secret Codes part 1 and for Nokia S60’s phones. To enter theses codes, the phone must be in the idle screen (not in the menu screen). What is idle screen? This is the screen where you see the operator name, date, time, battery level, signal strength and some other stuff. You can switch between idle screen and menu screen using Menu key
*#0000# – Display the software version, the date when the software was built and the phone model. In some cases, the phone model is not the one used by marketing. It is the internal model used inside Nokia. For example, RM-91 is the internal name of Nokia N80.

There are times when a minor error in the Windows Registry or a Virus Infection, can make your system unbootable. In such a condition a properly configured USB drive on hand with Bart Lagerweij’s free utility (BartPE), is a handy replacement for windows operating system.
