Week 13: Clear

This week was about "Computer Security, Ethics and Privacy" and once again very clear. There is actually nothing difficult to understand in this topic, nevertheless it is important to hear about it. Especially in today's business environment computer security gets more and more important and crucial. Losing data to others might hit a business very hard. Securing your data is therefore of utmost importance for almost every business. The timeline of notable computer virueses and worms shows that there have always been, and will probably always be new viruses on the web, which might harm a business severely. In April 2008, the number of viruses, worms and trojans in circulation has topped the one million mark. Programmers try to steal data with the help of these malware and expect to get paid in exchange. To not fall into that trap, you should always backup your data and use firewalls and other safety methods.

As a private person you should never respond to any spam emails. Even if you answer with a sentence like "Please to not send me any email any more!" you totally fall into a trap. This response shows the creator of the spam mail that your email adress is indeed valid and thus encourages him/her to send you even more messages. Therefore, be always aware of spam mails, never reply and only trust sources you know.
