Terrorism refer only to those violent acts which are intendedto create fear (terror); are perpetrated for areligious, political or, ideological goal; and deliberately targetor disregard the safety of civilians.Cyberspace refers to the global network of independentinformation technology infrastructure, telecommunicationnetworks and computer processing systems in which onlinecommunication takes place.CYBERTERRORISM

Denning definescyberterrorism as:Unlawful attacks and threats of attack againstcomputers, networks, and the information storedtherein when done to intimidate or coerce agovernment or its people in furtherance of political orsocial objective.
  6. 6. For any hacktivist, it is very cheap, speedy and straightforward to initiate attacksagainst critical infrastructure.Cost of personal computerand internet access Less than a minuteUsing freely availableintruder toolsIt is costly, long term and intricate to take the steps needed to harden theinformation infrastructure to make it less vulnerable to attack, and to facilitate inresponding more effectively and efficiently when attacks do happen.International efforts andfundingResearch, developmentand deploymentTechnically andpolitically
  7. 7. SOME ILLUSTRATIONSIn 1996, a computer hacker allegedly associated with the WhiteSupremacist movement temporarily disabled a Massachusetts ISP anddamaged part of the ISPs record keeping system. The ISP had attemptedto stop the hacker from sending out worldwide racist messages under theISPs name. The hacker signed off with the threat, "you have yet to seetrue electronic terrorism.

  8. 8. TOOLS ANDTECHNIQUESCyberterrorism flourishes on the development ofnew technology. New tools and techniques areinvented almost daily for cyberterrorism. Some ofthem are:Viruses, Worms and MalwaresThese are the basic tools for any cyberattack. Hacktivist will hack into systems andupload any virus or worm which can result insystem crash.Internet and downloadedapplications are the majorsources of malwares
  9. 9. Distributed Denial-of-service(DDOS)
  10. 10. Unauthorized InstructionsDomain Name Service (DNS)AttacksPotential Attacks
  11. 11. CONCLUSIONCyberterrorism is evolving concept, and thereis possibility of critical damages toinfrastructure, networks and cyberspace, ifnot taken seriously.Cyberterrorism is a complex issue that is vitalfor information security specialists and to someextent the society to recognize. One must beconscious of all of its characteristics in order tobetter evaluate how and where the terroristsare likely to attack our approach.
