Direct Attack hacking

Hacker is a term that applies to anyone who writes computer program code. Cracker is a term that applies to people who use their skills to attempt to access other computer without permission.

There are even programs shared across the internet, allowing people with less skill to mount an attack. Broadly, two types of attacks can be considered: indirect attack and direct attack. A direct attack is a hacker using a personal computer to break into syst

Direct attacks are performed at the sensor level outside the digital limits of the system and therefore, no digital protection mechanism can be used against it.

Direct attacks originate from the threat itself. It would take the form of hacking into a computer system and rewriting or stealing information. This would have a great impact on organizations offering on-line services, since these on-line services could be damaged, modified or destroyed.

Neither problem is that of the organization were not able to determine where the security risk lies, the direct attacks would be re-occurring.

In a direct attack an imposter can either change his biometric characteristics in order to evade identification or claim an authorized user’s identity by simply posing himself or by presenting a falsified biometric trait of that user.

The impact of the attacks would be to publicize the hackers and destroy the credibility of the organization offering the on-line services especially to current and future customers.

What is computer hacker?

In the computer security context, a hacker is a person who attempts to breach the security of computer system by access from a remote point, especially by guessing or otherwise obtaining a password.

The person had an instinctive knowledge enabling him or her to develop software apparently by trial and error.

The broadest term of hacker would be a computer expert who is capable of clever or novel solution to computer problems.

Hacking, in computerese, is the obsessive use of computers, or the unauthorized access and use of networked computer system. Illegal hackers (also called crackers) frequently assault the internet and other networks to steal or damage data and programs.

Although many person in the computer industry continue to use the term ‘hacker’ to pick out programmers of distinction, the term ‘hacker’ is now used by most person only to pick out persons who intrude upon systems and machines belonging to other people without any meaningful authorization.

Hackers can monitor E-mail, Web server access, or file transfer to extract passwords or steal network files, or to plant data that will cause a system to welcome intruders.

A hacker may also use remote services that allow one computer on a network to execute programs on another computer to gain privileged access within network.

Hackers, crackers and computer criminals have a growing palate of tactics and technologies that can used to achieve their purpose.

This include harvesting passwords from unsuspecting user, stepping stones that conceal the ultimate source of an intrusion and stolen storage space to serve as caches for among other things, attack programs, password files or stolen card credit numbers.

The good and bad hackers have similar personalities. What separate them is their ethics.

How does ‘Denial of Service’ attack works?

A denial of service attack is an act of sabotage that attempts to flood a network server or Web server with so many requests for action until it crashes simply cannot handle legitimate requests any longer, causing legitimates users to be denied service.

The attack overwhelms the system’s ability to process web traffic and eventually crashes it.

Denial-of-service attacks can compromise the computers in a network. They can disorganize an organization’s functioning, depending on the nature of the attack.

University security experts were the first to discover the threat of denial of service attacks hiding in the university computer systems. For example, David Dittrich of the University of Washington discovered denial of service program files stored on the university servers’ months before the first widely publicized attacks on E-ecommerce web sites.

Denial of service attacks can be very costly in terms of business lost such as when an e-commerce site is shut down.

The attack, which would typically come from several compromised machine at once, would consumed network bandwidth and use up processing unit cycles on the target machine.

The goal is to stop hosts or networks for communicating in the network or to disrupt network traffic.

The concern would be what is called distributed denial of service attack where take a lot of compromised end systems and flood a server with the intent of making many request or delivering so much traffic to it that it falls off the network.

One of the reasons it takes so long to stop a denial-of-service attack is the hacker sends the bogus traffic using fake IP addresses.

Computer Hacking

In the 1960s, hackers were perceived as skilled computer wizards who curiosity would lead to technological advancement. At that time the term ‘hacker’ was used to describe an individual working with computers who was technically gifted.

Today , a hacker is a person who attempts to breach the security of a computer system by access from the remote point.

Although the term hacker still has both positive and negative connotation, hacking does not. The technical means of hacking have become ever more sophisticated. It refers to the trespassing or accessing of a website without authorization.

Hacking is often defined in terms of individuals who seek to gain ‘unauthorized access’ to computer systems, and the currently broadly accepted view of a hacker is someone who uses specialized knowledge of computer systems to obtain illegal access to them.

Unauthorized entry can led to legal consequences, particularly if a hacker is deliberately violating the website’s right to privacy.

Hacking provides one of the most widely analyzed and debated forms of cybercriminal activity, and serves as an intense focus for pubic concerns about the threat that such activity poses to society.

The use of computer for the purpose of material gain or mischief is a crime and can result in incarceration. 

People who use the internet for illegal purpose have been called ‘cracker’ within the hacker community in order to distinguish them from people who are simply demonstrated their knowledge.
