Hacking has a rather simple definition to it. Basically it is defined as the unauthorized use of a computer - especially when it involves attempting to circumvent the security measures of that computer, or of a network.
Hacking is not difficult to learn. Unfortunately, it may be too easy for someone that has a little time on his hands. This becomes especially obvious when it is found that a number of the hackers, at least those that are caught, are often only in their teens.
Beyond this, there are two basic types of hacking. Some only hack because they want to see if they can do it - it is a challenge to them. For others, however, it becomes an attack, and they use their unauthorized access for destructive purposes. Hacking occurs at all levels and at all times - by someone, for some reason. It may be a teen doing it to gain peer recognition, or, a thief, a corporate spy, or one nation against another.

By the way hacking has many levels. As you mentioned some methods are so easy and anybody can do it by just using a software.
ReplyDeleteBut in higher level, it is one of the most complicated matters in computer, and those hackers need high knowledge of computer and also talent, and these hacking is not just for fun but for specific purpose like financial or political.
By the way, why these talent and knowledge goes wrong??
You know that the hackers are very intelligent and creative, they also possess sophisticated ideas or talents that is highly knowledgeable, just that most of them use their gift for good intentions that will be beneficial to the public while some use their's for evil that makes it become hacking crime.
ReplyDeletegreat!
ReplyDeleteCyberTerrorism:
ReplyDeleteCyberterrorism is the premeditated, politically motivated attack against information, computer systems, computer programs, and data which results in violence against non-combatant targets by sub-national.is a phrase used to describe acts of deliberate, large-scale disruption of computer networks, especially of personal computers attached to the Internet, by the means of tools such as computer viruses.
To know the impact of the crime, since September 11, President Bush, Vice President Cheney, and senior administration officials have alerted the public not only to the dangers of chemical, biological, and nuclear weapons but also to the further menace of cyberterrorism.
I will site some examples:
Examples:
ReplyDeleteOne example of cyberterrorists at work was when terrorists in Romania illegally gained access to the computers controlling the life support systems at an Antarctic research station, endangering the 58 scientists involved. However, the culprits were stopped before damage actually occurred.
Secondly, more recently, in May 2007 Estonia was subjected to a mass cyber-attack in the wake of the removal of a Russian World War II war memorial from downtown Tallinn. The attack was a distributed denial-of-service attack in which selected sites were bombarded with traffic in order to force them offline; nearly all Estonian government ministry networks as well as two major Estonian bank networks were knocked offline; in addition, the political party website of Estonia's current Prime Minister Andrus Ansip featured a counterfeit letter of apology from Ansip for removing the memorial statue. Despite speculation that the attack had been coordinated by the Russian government, Estonia's defense minister admitted he had no conclusive evidence linking cyber attacks to Russian authorities. Russia called accusations of its involvement "unfounded," and neither NATO nor European Commission experts were able to find any conclusive proof of official Russian government participation. In January 2008 a man from Estonia was convicted for launching the attacks against the Estonian Reform Party website and fined.
Even more recently, in October 2007, the website of Ukrainian president Viktor Yushchenko was attacked by hackers. A radical Russian nationalist youth group, the Eurasian Youth Movement, claimed responsibility.
In 1999 hackers attacked NATO computers. The computers flooded them with email and hit them with a denial of service (DoS). The hackers were protesting against the NATO bombings in Kosovo. Businesses, public organizations and academic institutions were bombarded with highly politicized emails containing viruses from other European countries.
Australia, Computer viruses have degraded or shut down some non-essential systems in nuclear power plants, but this is not believed to have been a deliberate attack.
Mostly non-political acts of sabotage have caused financial and other damage, as in a case where a disgruntled employee caused the release of untreated sewage into water in Maroochy Shire,
Since the world of computers is ever-growing and still largely unexplored, countries new to the cyber-world produce young computer scientists usually interested in "having fun". Countries like China, Greece, India, Israel, and South Korea have all been in the spotlight before by the U.S. Media for attacks on information systems related to the CIA and NSA. Though these attacks are usually the result of curious young computer programmers, the United States has more than legitimate concerns about national security when such critical information systems fall under attack. In the past five years, the United States has taken a larger interest in protecting its critical information systems. It has issued contracts for high-leveled research in electronic security to nations such as Greece and Israel, to help protect against more serious and dangerous attacks.
Are there negative effects of all the above mentioned attacks?
Yes, there are unhealthy effects, like, Cyberterrorism can have a serious large-scale influence on significant numbers of people. It can weaken countries' economy greatly, thereby stripping it of its resources and making it more vulnerable to military attack.
ReplyDeleteCyberterror can also affect internet-based businesses. Like brick and mortar retailers and service providers, most websites that produce income (whether by advertising, monetary exchange for goods or paid services) could stand to lose money in the event of downtime created by cyber criminals.
As internet-businesses have increasing economic importance to countries, what is normally cybercrime becomes more political and therefore "terror" related.
Are there control measures against cyberterrorism?
So far Yes, there are some controls.
ReplyDeleteOn November 2, 2006, the Secretary of the Air Force announced the creation of the Air Force's newest MAJCOM, the Air Force Cyber Command, which would be tasked to monitor and defend American interest in cyberspace. The plan was however replaced by the creation of Twenty-Fourth Air Force which became active in August 2009 and would be a component of the planned United States Cyber Command
On December 22, 2009, the White House named its head of Cyber Security as Howard Schmidt. He will coordinate U.S Government, military and intelligence efforts to repel hackers.
The US Department of Defense charged the United States Strategic Command with the duty of combating cyberterrorism. This is accomplished through the Joint Task Force-Global Network Operations (JTF-GNO). JTF-GNO is the operational component supporting USSTRATCOM in defense of the DoD's Global Information Grid. This is done by integrating GNO capabilities into the operations of all DoD computers, networks, and systems used by DoD combatant commands, services and agencies.
Please you can comment on more control measures to apply to get rid of cyberterrorism crime.
