Hacking occurs because there are errors in the computer software that may

expose the computer to the same problems that result from the intended

dangers .

Who perform hackings:

Professionals:

They are distinguished people with an accurate knowledge of computer

software and a high ability in programming

Amateurs :

They are people with relatively limited experience in programming and they

search for ready made programmes to use in hacking .

Security Concept

Security means also managing and organizing relationships and

communications inside the system without an effect on computer users.

Information Ethics

What is mental property and how to protect it?

When you deal with data, you need software that can help you organize

and analyze Data and you need to make the necessary processing to get to

the correct information. The owners of these programmes must protect their

mental property. This is what we call mental property and how to protect it.

We find that computer programmes are protected by laws such as…

Publishing and Copyrights.

Copyrights --

Copyrights are given to any person who had mental production and has not

published it. Copyrights mean that no one is allowed to copy or publish any

part of it. This is considered breaking the laws of Copyrights.

International agreements

These agreements are considered licenses to deal with the programmes.

The license is an important part that should be enclosed with the programme. It

starts with a title of "Giving Liceses " that explains how to use the programme

and the restrictions imposed on borrowing or hiring programmes and also the

gurantees defining the programme.

Where can we find programme licenses?

- When you buy any programme, you will find the license agreement in one

of the following forms:

- Handouts attached to the product.

-A print out in the user's guide inside the cover.

- A web page from the programme
