The sentence is increased by 25% if they steal personal information. The sentence is increased by 50% if they share the stolen information. If posted on the Internet, sentence is doubled! Conclusion: Conclusion User awareness is key to a secure computer/network Do not open suspicious files/emails Verify ActiveX/Java prompts Avoid using P2P programs Avoid downloading freeware If attacked, disconnect the network. Do not turn off the computer Without Careful Attention To These Issues, The Uncontrolled Interconnection Of Existing Systems, On Which People And Organizations Are Critically Dependent, Will Continue To Create Huge, Ill-defined And Defenseless Super - Systems. So We Must Pay Attention To All Those Issues And Protect The World From Cyber Crime.
