Computer hacking

The word summons up thoughts of malicious computer users finding new ways to harass people, defraud corporations, steal information and maybe even destroy the economy or start a war by infiltrating military computer systems. While there's no denying that there are hackers out there with bad intentions, they make up only a small percentage of the hacker community. The term computer hacker first showed up in the mids.

Print Advertisement Julie J. This seems like a straightforward question but it's actually quite complex in its implications, and the answer is anything but simple. The trivial response is that hackers get inside a target computer system by exploiting vulnerabilities, but in order to provide more detail, let's start from the beginning.

The term hacker is fairly controversial in its meaning and interpretation. Some people claim that hackers are good guys who simply push the boundaries of knowledge without doing any harm at least not on purposewhereas crackers are the real bad guys. This debate is not productive; for the purposes of this discussion, the term unauthorized user UU will suffice.

This moniker covers the entire spectrum of folks, from those involved in organized criminal activities to insiders who are pushing the limits of what they are authorized to do on a system.

Next let's explore what it means to get inside a computer.

Computer hacking

This can refer to gaining access to the stored contents of a computer system, gaining access to the processing capabilities of a system, or intercepting information being communicated between systems. Each of these attacks requires a different set of skills and targets a different set of vulnerabilities.

So what do UUs take advantage of? Vulnerabilities exist in every system and there are two kinds: Known vulnerabilities often exist as the result of needed capabilities. For instance, if you require different people to use a system in order to accomplish some business process, you have a known vulnerability: Another example of a known vulnerability is the ability to communicate over the Internet; enabling this capability, you open an access path to unknown and untrusted entities.

Unknown vulnerabilities, which the owner or operator of a system is not aware of, may be the result of poor engineering, or may arise from unintended consequences of some of the needed capabilities.

By definition, vulnerabilities may be exploited. These can range from poor password protection to leaving a computer turned on and physically accessible to visitors to the office. More than one technical exploit has been managed simply by sitting at the receptionist's desk and using his computer to access the desired information.

Poor passwords for example, a username of Joe Smith with an accompanying password of joesmith are also a rich source of access: Attempts to make those passwords more complex by replacing letters with numbers, such as replacing the letter O with the number zero, don't make the task much harder.

And when a UU can utilize a valid username-password combination, getting access to a system is as easy as logging in. If a target system is very strongly protected by an architecture that includes both technical controls such as firewalls or security software, and managerial controls such as well defined policies and procedures and difficult to access remotely, a UU might employ low-technology attacks.

These tactics may include bribing an authorized user, taking a temporary job with a janitorial services firm, or dumpster diving rifling through trash in search of information.

If the target system is not so strongly protected, then a UU can use technical exploits to gain access. To employ technical exploits a UU must first determine the specifications of the target system.Welcome back, my rookie hackers! Now that nearly everyone and everyplace has a computer, you can use those remote computers for some good old "cloak and dagger" spying.

No longer is spying something that only the CIA, NSA, KGB, and other intelligence agencies can . The question “how to hack a computer” is probably the one that is most frequently asked by many Internet users and hacking enthusiasts.
