IS130- Chapter4. Ethics and information security^{0}

As we use computer and internet every day, we sometimes suffer from infringing our information, fraud, getting virus, being hacked or spam e-mail. Also I use internet a lot, from reading newspaper to using online banking, not to mention of using e-mail. In this article, it represents that one of the filtering spam mail companies takedown cut global spam traffic by about 70 percent last year, but this year, average spam volumes have increased gradually. Because spammers try to rebuild technology, using more technically advanced tools. Also, it warns that negligent users are easy to click the spam mail. After that, their computers could be infected with viruses. I use e-mail since I was middle school student. E-mail is very useful and easy to send and receive, no matter how far. I am used to send e-mail to Chinese friend and at first time I liked it and thought using e-mail is very convenience. However, I felt sick of spam mail. There became hundreds of spam mails and I hated to receive them. Although there are still lots of spam mails today, powerful filtering of spam becomes, so we can use email without annoying.
It costs a lot of money to send and prevent unsolicited emails and according to some statistics; it was over 14 billion dollars. Actually, spammers violate email privacy policy and anti-spam policy.
I hope that people do not suffer from unsolicited emails anymore and we need to be cautious of spam, because it could be change to virus.
