  27. 27. The proportion of cybercrime that can be directly or indirectly attributed to terrorists is difficult to determine. However, linkages do exist between terrorist groups and criminals that allow terror networks to expand inter- nationally through leveraging the computer resources, money laundering activities, or transit routes operated by criminals.
  28. 28. The use of information technology by terrorist groups and individuals to further their agenda. This can include use of information technology to organize and execute attacks against networks, computer systems and telecommunications infrastructures, or for exchanging information or making threats electronically. Examples are hacking into computer systems, introducing viruses to vulnerable networks, web site defacing, denial-of-service attacks, or terroristic threats made via electronic communication.
  29. 29. 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. Cyberterror 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 &quot;terror&quot; related.

  32. 32. Use anti-virus software and firewalls - keep them up to date Keep your operating system up to date with critical security updates and patches Don't open emails or attachments from unknown sources Use hard-to-guess passwords.
