At the present time website security is a very important issue for numerous site administrators. Protecting a website from hackers’ attacks prevents copying its content and stealing information and protects from other unwanted consequences. The majority of websites have common access. IP addresses are not filtered by web application firewall. This increases the danger of hacker attacks. There are a lot of reasons for separate individuals to attack websites, among them being: defacing (changing the front page); getting control over a server; stealing of database of personal information of users (phone numbers, e-mails, logins and passwords etc.) with the purpose of spamming and others. Moreover, individuals who want to try luck using their hacking skills can attack websites for fun.

There are 5 non-program options of website security.

1. Select complicated passwords.
At present, there are many automatic programs which try access websites by the means of generating consequent numbers. The fastest program available on the market can cope with an 8-symbol digital password within a year. There are 2x1012 of possible variations of passwords consisting of numbers only, so it is advised to use alphanumeric combinations. Microsoft .Net Security application can be used for assistance with passwords.

2. Limited access
It must necessarily be mentioned that it is not recommended to entrust the rights to access a website to random people. Moreover, it is not recommended to give the rights to add HTML-codes to every user, especially if a page is not protected by a web application firewall.

3. Antivirus Protection
It is recommended to use antivirus systems with fresh databases and an option of regular upgrade. Free antivirus programs found on commercial download websites are limited for increasing website security since these cannot guarantee reliable protection.

4.
Passwords in FTP-clients.
It is recommended not to keep passwords in FTP-clients. As a matter of fact, it is comparatively simple to steal a password from a file (even a cipher-protected password).
Special password managing programs are used to store passwords securely (if website administrators do not rely on their memories). For instance, Microsoft .Net Security can be rather helpful for this purpose. These programs normally require a separate password for access. In this case administrators are expected to keep in memory only one password that is considered to be easier and more convenient.

5. Unknown links
It is recommended not to click on unchecked links in order to preserve information, avoid getting viruses and store data in safety.

Every day billions of dollars in transactions and millions of people travel on the information super highway and internet and web security have become of paramount importance. There are threats all around on the internet and persons and businesses need to be assured that their assets, whether financial or information, are safe. Web developers and internet security specialists work hard to make sure that they are one step ahead of those who like to cause mayhem on the web either for personal satisfaction, political purposes, or theft. You may be wondering "How does web application security work?". Here is a brief overview.

Since the explosion of social networking and internet business transactions, hackers and more prevalent and insidious devices such as malware, adware, and spyware have many more opportunities to creep in and access your personal and financial information. Web application developers and programmers have to be diligent in making sure that users information is safe. Many attacks are the result of flaws in programming and oversight. Along with better attention to detail there are many technical solutions to help insure the integrity of user information. Tools such as web application scanners, static source code analyzers, and web application firewalls are invaluable in aiding in the design of web applications that can ward off breaches in security.

The Open web application security Project conducted a forum to identify the top ten threats to web application security. Some of these threats were identified as being cross-site scripting, broken authentication, cross-site request forgery, security misconfiguration, insecure cryptographic storage. failure to restrict URL access. insufficient transport layer protection, unvalidated redirects and forwards, and several others.

Aside from diligence at the development stage, there are other tools which help to insure user end security and integrity of data transfer. Application layer security provides protection at each level in the transaction process from user input to data transfer to end point. Web application firewall software is built to application specific needs. These programs use specified criteria to block erroneous or unauthorized access to data from malevolent users, viruses, and malware, adware, and spyware. If the input does not meet this critria or the firewall program senses other attempts to access data and user information, access to that application or site is blocked.

With greater awareness of risk, better technology, and invaluable tools such as application layer security and web application firewall, developers are the first line of defense in protecting you and your information.

General Questions

  • How to choose a company to install my PV system?

Only a company with experience, skilled manpower to design great products can make a solar system that will produce the max for years. Check out some systems that have been installed, are there any customers who can recommend what products the company uses.

  • Does the system run separately from the electric company?

The system runs parallel to the electric company. The building is usual connected to the electric company that also receives an additional input of the solar inverter system.

  • What are the system components?

The PV system consists of a system of solar photovoltaic panels.

  • Do I need batteries?

No. Grid-connected system does not need batteries. The electricity is produced through production that is installed when you connect the system by the electric company, the customer is credited for production. Batteries are installed only in a situation where backup is also required.

  • Does the solar system run as a backup during a power failure?

No. By law, when a power failure accures, the system automatically stops itself, in order to prevent the power generated in the solar system with general network out which may cause electric shock.

  • Can the solar system be combined with a grid-connected system backup?

Basically, it is possible by adding an additional power converter (a different kind, designed for batteries) and cells. The backup will be a member of several circles of power in them want to back up.

  • Is there a system to deal with regularly?

Treatment is minimal. There's only worry about the cleanliness of the panels on getting maximum yield. The recommendation is to clean the panels every few months, on periods and areas where dust piles up in the extreme (a desert area, dust storms) more frequently.

What factors may affect the efficiency of the system and its production?

As mentioned, the solar panels cleaness is important. In addition, high temperature reduces the efficiency of the panels (temperatures over 65 degrees on the panel). Usually try to install the panels which have a maximum natural ventilation and warm air so they are not trapped behind the panel.

  • What is the expected life term of the system?

Most of the leading manufacturers offer a 20 year warranty for solar panels performance. Voltage converter is an electronic device with a warranty of five years and is planned to work for many years.

  • What happens at night?

In fact the house is connected to the electric company. At night, and during times with high power home solar system's production, power is taken from the local electric company.

  • I want to install a system, but my neighbor's solar panels will cause the concerned radiation. Does he have a point?

No. Solar panels are passive and do not cause any radiation.

  • If I do not have enough space to install the system on the roof, is it possible to install panels in an open area near the house? If so, do any necessary certificates (of the relevant council or other body)?

Technically, the panels can be installed wherever there is direct radiation. About certification and licensing issue related to the construction industry you must contact the Local Authority.

  • Is it possible to install the system onto an apartment building?

Technically there is no problem. However, the roof space is usually small, and in many cases it is defined as a shared.

  • How much electricity does the system produces?

The system produces electricity according to its size, location in the country, and quality installation. For example, a 1000 watt size system, will produce (on average, depending on where in the country) 150 kwh a month. In the winter it will produce somewhat less than in the summer.

  • Is it possible to connect an electricit home wind turbine?

There is currently no regulations for installing wind turbines, and practically it is very problematic in urban areas. Wind turbine should have an area with strong winds and no objects interfere. In fact, there is almost no domestic turbine market.

  • What is the necessary roof space?

The area needed is reletive to the size of the system. A 1000 watt system will cover about 10 square meters.

  • Can I install on every roof?

You can installed on almost every type of roof.

  • I plan on building a new house. What considerations should I consider? Do I need special preparation?

At Home Design prepare spare shading roof area facing south. In terms of domestic power, electricity and plumbing have to worry about who comes closet to the power system area.

  • Do  all home appliances work with solar power?

Yes all the devices will work as usual.

  • Will the system produce electricity in the winter?

If solar radiation conditions are good enough - it would. The output will be lower by 30-50% in the winter.

  • How do I know that the system produces electricity at one point?

There are two options: 1. A converter can be ordered with a voltage monitor that shows a clear view all the production data.
2. Monitoring system can be ordered to allow online access, so you can view the system performance at any point of time.


Choosing the system and the installation process

  • I would like to install a system. What should I do?

First, you should read all the questions and answers on this page, make a copy of an electricity bill, measure the roof area, and plan your budget. Then you should call and consult with a solar energy expert - to get further explanations and price quotes.

  • Are there differences between the different panels manufacturers?

Sure. Quality manufacturer manufacture panels of different sizes - is also possible to adjust the optimal size for the building. In addition, there are differences in production efficiency between the different panels manufacturers. Most importantly, only known and experienced manufacturers can stand behind their warranty.

  • Can I take the system with me to a new house?

Yes. This would involve only the dissolution of the new lineup. The system performance is not expected to change.

  • Can I install the system myself?

Since the system is connected to the electricity grid, be sure to install it by a qualified installer (electrician or electrical engineer), or by a company which can provide professional service.

  • How long will it take to install grid-connected solar system?

After a short survey in the installation, it will take several weeks to prepare the necessary ingredients, and the installation itself will usually within one business day. The amount of time to confirm the local authority electricity company is estimated by 4-6 weeks.

  • Do you have insurance against external damage or damage caused by nature?

We recommend that you consult with a house insurance agent. The system should be treated like any other system connected to the building.
