  7. Malware • Adware • Spyware • Trojan Horse • Crimeware • Viruses • Worms

  8. Social Engineering • Phishing • Baiting • Spam

  9. Who is the Target?

  12. Why

  13. Cyber vandalism • To cause harm or data loss • Corrupting other people’s hardware • Profit motive • As a prank • To take control of users' computers for black-market exploitation • To help in profit for spyware where programs are designed to monitor users' web browsing, display unsolicited advertisements, or redirect affiliate • marketing revenues to the spyware creator.

  14. Prevention

  15. “A detection system may detect suspicious activity, but where is the protection from fast acting attacks? A prevention system must identify and stop malicious attacks before they do damage and have a chance to infect a system.”

  16. Preventing Malicious Attacks on the Internet • Along with intrusion prevention, a useful tool for the home user is to become familiar with some of the tricks and techniques that hackers use to break into systems. • -scanning systems for weak spots, like an operating system that has not been upgraded or recently patched • the use of malware to record important information from the computer (e.g., passwords or financial information). • Remember that a system may not always be attacked to steal information; it may also be attacked to be used as a storage site for illegal content (such as pirated movie downloads) or a system could be recruited into an online 'bot army.'

  17. Preventing Malicious Attacks on the Internet • To increase security of the home computer, the home user can take a few relatively simple steps. • One of the first steps in computer hacking prevention is to make • sure that all of your software is up-to-date. • -Another measure that any home user may take is to install a firewall. The firewall’s purpose is to stop unauthorized contact or entry • onto the system. • -Different applications on the market will scan and remove • malicious code that has found its way onto a hard drive. Running • various virus software applications yields benefits as well.
