Section 3 :
                                                             Security Awareness
Security Awareness, it is very important for all people who uses internet even governments that use system connected to the internet. So all people must start learning about the risks and attacks in the internet and how do they happen to avoid them, so risks can happen like system down as we hear all the time also attackers like hackers want destroy the system or steal information for that system database. So all of must be updated to these changes and this awareness for every one using internet to get more detailed information of internet security.

                                                               Security Assessment 
Security Assessment is the process of employing administration tools and techniques to verify the configuration also the physical protection, while this process is for companies and organizations not for normal users. So the information technology man in the place go throw system to find mistakes and fix them by re-programing it, in addition he go and check the physical condition if its cracked or not like for atm if there was a gap the hacker just needs to plug his usb and can steal what he wants from that bank.

                                                                Source code analysis
Source code analysis, it is also a process for companies and organizations to improve their security defenses by going back to the system programs which is the language used like java or HTML to find gaps and backdoors that was made by who did the system it self for example if you started a company you will bring an IT man to design a system for this company and you don’t know if he put a backdoor or not, also check the encryption if can be bypassed easily or not to improve it.
Section 4 : 

Articles ranking 
1-Security Awareness
2-source code analysis
3-security assessment 



I think Security awareness is the best article , because the most important thing its to know what's happening around you in the internet world for your personal life, to keep your device safe from hackers or personal accounts over the social media like Facebook and twitter, or even your career life like if you are working in a bank to keep customers accounts safe from attacks and being lost or even being fraud by some fake e-mails and that will for your bank to lose both people and repetaion.And for my area all the time I hear or even I read in the newspaper that an military organization has been hacked and all officers information being published through the internet and as a result that would put their life in danger, so we should protect our self's before that happens to us which I mean is our private organazitions.Finally what I want to know is how these attacks happen exactly how do the hackers learn, also why do they attack and the governments can discover them and what procedure followed to catch them and what kind of punishment they get ?

section 1 - research question

The main question is whether developing wind energy will help us in the future? Like in costs and efficiency; do we need more wind farms or less? Also how can we reduce the costs and produce enough energy? And I asked these questions because wind energy is clean and renewable energy; also there are a lot of countries that do not have fossil fuels or oil to produce energy and they need an alternative solution.

section 2 - background report summary

We can increase the efficiency by design, and the best design would be suitable for the location it would be placed in and how it's installed, for aerodynamic efficiency also use   material that is durable and reliable and lighter rotor blades; also twist and sweep and place them at a certain height.

Moreover we can reduce the costs by developing the technology used, and there is a technology called circulation control, this aerodynamic could allow wind turbines to produce significantly more power than current devices at the same wind speed. the goal will be to make the generation of electricity from wind turbines by eliminating the need for complex blades.

In addition, we can generate by installing small wind turbines over houses, and we need  three parts: a generator and blades with a small tower. Also, we should take into consideration how much wind is flowing per day and obtain permission for these things from government.

part 3 - survey results

In question one, out of 16 participants 14 of them know that wind energy is a source of power and it's green; also that depends on air flow and in addition that its renewable, and two just didn't know while only a  few people knew how wind energy is generated.
Most of the answers of question 2 say that wind energy is not cost effective while only a few believe that wind energy production is enough. For question 3 14 out of 16 which make 87.5% of participants say that we need more wind farms and 2 out of 16 which are 12.5% say that we don't need.In question 4, 81.25% of answers point out that wind energy is clean and 18.75% were not sure and said no. Next question 5 15 out of 16 agree that we need to develop wind energy which is the majority of participants. Also in question 6 is the opposite of question 5 were most of them said that wind energy production is not enough.In question 7 everybody knows that the advantages are more than the disadvantages. For question 8, 11 out of 16, 68.75% want to build small wind turbines over their home, and 31.25% don't want. For question 9, 15 out of 16 agree that countries do not have fossil fuels should depend on wind energy and only one refused. In question 10 most of the answers believe that within future developments wind energy will be efficient. About question 11, people said we need to change materials and do more research to reduce the cost of wind towers. Finally for question 12 people do not have more comments about this topic.

part 4 - result discussion

Since wind energy is not a brand new solution, most of the participants knew how wind energy is working and its effects. While the production of the wind in not enough, all answers in the survey point that we need more wind farms, because all of them said energy from the wind is not enough. Also, most of them wanted to develop and reduce the costs of wind energy because it will increase the rate, and it would be a great solution for the future. All answers of the survey matched my justification.

Next question 5 15 out of 16 agree that we need to develop wind energy which is the majority of participants. Also in question 6 is the opposite of question5 were most of them said that wind energy production is not enough.
In question 7 everybody knows that the advantages is more than the disadvantages. For question 8, 11 out of 16 ,68.75% want to build small wind turbines over their home, and 31.25% don't want. For question 9, 15 out of 16 agree that countries do not have fossil fuels should depend on wind energy and only one refused. In question 10 most of the answers believe that within future developments wind energy will be efficient. About question 11, people said we need to change materials and do more research to reduce the cost of wind towers. Finally for question 12 people do not have more comments about this topic.

CLO PHASE 2

Justification:
Wind energy is one of the renewable energies, and it's a clean one, not like fossil fuels but it's not cost effective, so we need to develop it to get more benefit and reduce its cost; then a lot of countries will adapt this idea, mostly the countries that do not have fossil fuels or gas so as a result of developing we will get more energy and reduced rates of co2 in the air which as a result will decrease global warming effects, so in the future our new generations well have more options of energy with reduced costs and also better environment and better health that we have now, so developing this energy well help us in many fields.
