Open source and closed sources

Open source is the core of the open system, allowing users to modify or recompile the system kernel to open source, all known as open sources. At present, open source software in the market, many people may think the most obvious feature of open source software is free, but in fact, it is not the most important feature of open source software is open, that is, anyone can get the source code of the software, modify the study, or even re-release, of course, within the limits of copyright. Closed-source (Closed source) closed Source (Closed source) is a term invented as an antonym of open source and is used to refer to any program that is not qualified as an open source license term. Generally, it means that only a binary version of the computer program that they license will be obtained without the source code of the program, and the translation modification of the software is almost impossible from a technical aspect. The source code of this development model is regarded as the business secret of the company, so groups that may gain access to source codes, such as schools, must sign a non-disclosure agreement in advance.

Open source System In fact, the user has two groups, one is the programmer, they are most concerned about the source code, can be carried out two times, the second is the ordinary end user, they only care about the software function is not strong enough. Open source system should focus on "open", is acceptance, tolerance and development, seek common ground, mutual benefit and win, is the essence of open source

Closed sources are more secure than open source

Among the Chinese, the need for security is far greater than the need for privacy, and the rise of 360 is why 360 of browsers, computer stewards and even search engines can be unstoppable. Not because of his technology and software, but because 360 has become synonymous with security, users feel at ease.

Therefore, the security of online shopping system is also a very important measure, because it involves capital transactions, it is more sensitive to know. Users think open source system source code is open, hackers know its vulnerability, so closed source is more secure than open-source, but in recent years, the case of the closed software has been attacked countless, overturned the previous assertion. How to determine whether a software or system is not the security of open source or closed sources, but in the program's rigor and update frequency, closed-source system for hackers, just a lot of decryption procedures.
