Everybody is talking about it... Privacy and Security are very important topics concerning the internet. First of all, lets check out the issue of privacy on the internet. Is there any privacy at all? Well of course there is, if you stay out of the social networks and don't share anything.
But with Facebook, Twitter and Google+ around, there are only few who can really stay out of all this. So we all need to find ways to protect our privacies, that is, if we want to do so.
There are people who don't care about privacy and share whole their lives on the internet with just everybody.
I for example am signed up in Facebook and Twitter. On Facebook I had to update all the privacy settings after the Timeline was introduced. Before I wasn't worried that much, but the Timeline didn't sound so well... I checked my new settings and found out that I had to change lots of things and uncheck certain permissions, otherwise Facebook would have the right to share my information with everyone. So everybody has to decide for themselves whether they want to share so many information or not.
As I mentioned there are people who want to share information deliberately. There are ways to share them professionally. This is called Personal Marketing. On websites like Xing or LinkedIn people can create a professional profile and look for jobs.
Security is another highly discussed topic when talking about the internet and its usage today.
There is no way to be online and be totally safe, that is just not possible as the hackers can find a way through any kind of security measurement they want to when they try hard enough.
But there are a few things everyone can do to protect themselves, like choosing complicated passwords or making use of security software when working on a computer with Windows on it or switching to a Mac as there are almost no viruses or trojans that can infect a Mac ;-)
I for myself am using Apple devices and until now never had a problem with viruses or trojans, I am using passwords that are really really hard to guess and hope that will keep me away from security problems.
I also have a Mac and had never problems with viruses or trojans, but that will almost certainly change soon. Viruses and trojans for Unix-like systems are hard to come in, for example the Flashback and the DNS-Changer trojan.
