What Is Hacking ? <ul><li>Hacking is unauthorized use of computer and network resources. </li></ul><ul><li>The act of gaining access without legal authorization to a computer or computer network. A hacker first attacks an easy target, and then uses it to hide his or her traces for launching attacks at more secure sites. The goal of an attack is to gain complete control of the system (so you can edit, delete, install, or execute any file in any user’s directory), often by gaining access to a "super-user" account. This will allow both maximum access and the ability to hide your presence. </li></ul>
History Of Hacking <ul><li>Early 1960s <<...>> University facilities with huge mainframe computers, like MIT's artificial intelligence lab, become staging grounds for hackers. At first, "hacker" was a positive term that was used to describe a person with a mastery of computers who could push programs beyond what they were designed to do. </li></ul><ul><li>1983 <<...>> In one of the first arrests of hackers, the FBI busts six teen-age hackers from Milwaukee, known as the "414s" after the local area code. The hackers are accused of some 60 computer break-ins, including from the Memorial Sloan-Kettering Cancer Center to Los Alamos National Laboratory. One of the hackers gets immunity for his testimony; the other five get probation. </li></ul><ul><li>1984 <<...>> Eric Corley, who uses the hacking handle "Emmanuel Goldstein," starts 2600: The Hacker Quarterly in New York, which quickly becomes a clearinghouse for hacking information. </li></ul><ul><li>1985 <<...>> Underground journalists "Taran King" and "Knight Lightning" launch Phrack, an electronic magazine based in St. Louis that provides information about computer hacking. </li></ul><ul><li>1987 <<...>> A 17-year-old high school dropout named Herbert Zinn, known to authorities as "Shadow Hawk," admits he broke into AT&T computers at Bedminster, N.J. Federal authorities say the teen - who worked from a computer in the bedroom of his suburban Chicago home - was close to tapping into AT&T's internal operations and the company's central switching system. Zinn, becomes one of the first people prosecuted under the Computer Fraud and Abuse Act of 1986, which among other things makes it illegal to use another person's password. He is caught after bragging on an electronic bulletin board that he had attacked an AT&T computer. </li></ul><ul><li>1988 <<...>> Cornell University graduate student Robert Morris, 22, launches a "worm" program onto the Internet that he wrote to exploit security holes on UNIX systems. The worm, programmed to penetrate other computers on the network and replicate itself, quickly spreads to more than 6,000 systems - approximately 1/10 of the Internet at the time ö and virtually shuts down the network by hogging system resources. Morris, who is arrested soon afterward, says he didn't intend to cause the $15 million to $100 million in damage that experts say his creation wrought. He faces a maximum sentence of up to five years in prison and $250,000 in fines but receives three years of probation, 400 hours of community service and a $10,000 fine. </li></ul><ul><li>1988 <<...>> The Department of Defense severs the links between the unclassified Military Network, or Milnet, and the Arpanet - the early Internet - after it is discovered </li></ul>
History Of Hacking <ul><li>1989 <<...>> Five West German cyberspies are arrested on espionage charges as a result of detective work by Clifford Stoll, a University of California, Berkeley, systems administrator who detected and investigated their systematic intrusions into U.S. government and university computer systems. Three of the hackers, who were charged with selling the information and software they obtained to the Soviet KGB, were convicted and sentenced to prison terms, but none ever spent any time behind bars. Stoll later wrote the bestseller "The Cuckoo's Egg" about his pursuit of the hackers. </li></ul><ul><li>1989 <<...>> Kevin Mitnick is convicted of stealing software from DEC and long-distance codes from MCI, becoming the first person convicted under a new law against gaining access to an interstate computer network for criminal purposes.

The company says the hackers also have lifted log-ins, passwords and connect addresses for its computer network and says it has spent $3 million on increased security to combat the hackers. Three of the hackers are found guilty and handed sentences of ranging from 14 months to 21 months and ordered to pay restitution of $233,000 to BellSouth. </li></ul><ul><li>1990 <<...>> The Secret Service launches Operation Sundevil to hunt down hackers. Agents eventually seize computer equipment in 14 cities. </li></ul><ul><li>1991 <<...>> Police arrest Justin Tanner Petersen in Dallas for possession of a stolen car and find computer files that lead to charges that he broke into the TRW computer system. After his conviction, Petersen is approached by the FBI and the Secret Service to assist in computer investigations. He reportedly helps investigators with the Mitnick case, but in October 1993 he disappears and a short time later is declared a fugitive. He resurfaces in 1994, as a confederate of Kevin Poulsen in his radio-station contest-rigging scheme. (See 1993.) </li></ul><ul><li>1991 <<...>> The General Accounting Office reveals that Dutch teen-agers gained access to Defense Department computers during the Persian Gulf War, changing or copying unclassified sensitive information related to war operations, including data on military personnel, the amount of military equipment being moved to the gulf and the development of important weapons systems. </li></ul>
History Of Hacking <ul><li>1992 <<...>> Five members of Masters of Deception, a band of teen-agers based in the New York City boroughs of Brooklyn and Queens, are indicted for breaking into the computer systems of AT&T, Bank of America, TRW, and the National Security Agency, among others. Investigators used the first wiretaps ever in a hacker case to apprehend the hackers. One, Mark ("Phiber Optik") Abene, receives a one-year sentence; the others get off with 6-month sentences. </li></ul><ul><li>1993 <<...>> Kevin Poulsen is charged with using computers to rig promotional contests at three Los Angeles radio stations, in a scheme that allegedly netted two Porsches, $20,000 in cash and at least two trips to </li></ul><ul><li>Hawaii. Poulsen, already a fugitive facing federal telecommunications and computer charges, is accused of conspiring with two other hackers, Ronald Mark Austin and Justin Tanner Peterson, to seize control of incoming phone lines at the radio stations. By making sure that only their calls got through, they were able to "win" the top prize. </li></ul><ul><li>1994 <<...>> Two hackers identified as "Data Stream" and "Kuji" break into Griffith Air Force base and hundreds of other systems, including computers at NASA and the Korean Atomic Research Institute.

<ul><li>Hacker is a term often applied to computer software or computer hardware programmers , designers and administrators, especially those who are perceived as experts or highly accomplished in this field. A hacker is also a term used for someone who modifies electronics such as ham radio transceivers, printers or even home sprinkler systems for better functionality or performance. The term usually bears strong connotations that may be favorable or pejorative depending on cultural context (see the hacker definition controversy ). </li></ul><ul><li>In computer programming , a hacker is a software designer and programmer who builds programs and systems that garner the respect of one's peers. A hacker may also be a programmer who reaches a goal by employing a series of modifications to exploit or extend existing code or resources. For some, "hacker" has a negative connotation and refers to a person who gains illegal access to computers ( hacks ) or uses kludges to accomplish programming tasks that are ugly, inelegant, and inefficient. This derogatory form of the noun "hack" is even used among users of the positive sense of "hacker" (some argue that it should not be, due to this negative meaning; others argue that some kludges can, for all their ugliness and imperfection, still have "hack value"). </li></ul><ul><li>In computer security , a hacker is a person who specializes in work with the security mechanisms for computer and network systems. While including those who endeavor to strengthen such mechanisms, it is more often used by the mass media and popular culture to refer to those who seek access despite these security measures. </li></ul><ul><li>In other technical fields, hacker is extended to mean a person who makes things work beyond perceived limits through their own technical skill, such as a hardware hacker , or reality hacker . </li></ul>What Is a Hacker?
Ways To Prevent Hacking <ul><li>Implement a firewall -- A firewall is a barrier that keeps hackers and viruses out of computer networks. Firewalls intercept network traffic and allow only authorized data to pass through. </li></ul><ul><li>Develop a corporate security policy -- Establish a corporate security policy that details practices to secure the network. The policy should direct employees to choose unique passwords that are a combination of letters and numbers. Passwords should be changed every 90 days to limit hackers’ ability to gain possession of a functioning password. When someone leaves company, immediately delete the user name and password. The corporate policy should outline consequences for network tampering and unauthorized entry. </li></ul><ul><li>Install anti-virus software -- All computers should run the most recent version of an anti-virus protection subscription. Ideally a server should be configured to push virus updates out periodically to all client systems. Employees should be educated about viruses and discouraged from opening e-mail attachments or e-mail from unknown senders. </li></ul>
Ways To Prevent Hacking <ul><li>Keep operating systems up to date -- U pgrade operating systems frequently and regularly install the latest patches or versions of software, which are often free over the Web. If you use Microsoft Windows, check www.windowsupdate.com periodically for the latest patches. </li></ul><ul><li> </li></ul><ul><li>Don’t run unnecessary network services -- When installing systems, any non-essential features should be disabled. If a feature is installed but not actively used, it is less likely to be updated regularly, presenting a larger security threat. Also, allow only the software employees need to do their job effectively. </li></ul><ul><li> </li></ul><ul><li>Conduct a vulnerability test -- Conducting a vulnerability test is a cost-effective way to evaluate the current security program. This test highlights flaws and limitations in the program, and experts can offer suggestions for improvement. The best method for conducting a vulnerability test is to contact a computer consulting company and provide access to your system for a day or two. This will provide ample time for network appraisal and follow-up discussion and planning. </li></ul><ul><li> </li></ul><ul><li>Keep informed about network security -- Numerous books, magazines and online resources offer information about effective security tools and “lessons learned.” Also, the Web provides ample and very current information about security – type in the key words “network security.” </li></ul>
