CHAPTER 9Java Programming for Cybersecurity Applications

“Security depends not so much upon how much you have, as upon how much you can do without.”

—Joseph Wood Krutch

9.1 What Is Cybersecurity?

Cybersecurity is about threats from the Internet. As our lives become increasingly dependent on the Internet, cybersecurity is also becoming increasingly important. A recent example is the WannaCry virus attack in 2017, which affected more than 200,000 computers across 150 countries. The WannaCry virus targeted older Windows operating systems; it locked the affected computers and demanded ransom payments in the Bitcoin cryptocurrency. Hospitals with infected computers had to cancel operations, and factories had to halt production. Another example is the hacking of TalkTalk, a British telecommunication firm, in 2015 by a 15-year-old schoolboy in Northern Ireland. Thousands of customers' online details were stolen. The boy claimed he did this just to show off to friends. TalkTalk said the hack cost the firm £42m and lost 98,000 broadband customers.
