Int& Online Comms - Network & Data Security

I was told to do a project for my Int& Online Comms class, where I needed to do 3 or more posts about Data Security and Network for the coming few weeks. I was told to start the project on the 3trd of November and it had to be done for the beginning of December.
The Topics I choose to talk about were:

Rogue security software. why? A special type of threat is software that claims to be security software, then tricks the users to pay a sum of money to be really protected, sounds interesting.

How to protect Data from getting hacked (10 steps). Nowadays there are people that don't really understand the risks of having too much information online, or what they have to do to defend themselves against hackers.

Consequences of having your personal details on the internet and how to avoid that. I will have a video to back me up on this one. sometimes is just the case of being careful.

Consequences of having your personal details on the internet and how to avoid that

I've notice that some persons are not careful enough about the personal details that they release to the internet, and this is something that worries me. Most PC users don't really have the knowledge that we (computing students) have. Once in a while some websites pop up on my computer asking me for details and to me these might look dodgy, but to someone who doesn't have the same amount of experience, they might think its a safe website... And even if it is safe, there are some personal details that you just don't want to have in public sites like Facebook for example, Facebook is a really good place to find out people's address or date of birth, full name, phone number and things like that. it might sound harmless but you never know who's on the other side of the computer. Don't think you would like to have people ordering pizza to your place every 15 minutes, and you would need to pay for that... and this is just the minimum of what can happen.

Here is a example of what can happened if you're not careful with the personal details that you let others to access.
