How to prevent programmers from accessing core code in large companies?
For a company like BAT, if I am a programmer who has just joined the job, and now the company wants me to make a special module, and after it is completed, it needs to be integrated and tested. This special module requires user login to use it, then the Passport module must be included. There must be some encryption algorithms, private keys and other information in the source code of this module. We young programmers cannot see the code inside. So how to test it specifically? How do they ensure the security of their core business code?

Large companies generally turn passport into a service. You can only see the interface, not the implementation~
Just give you a packaged dll and header file
The dll has removed the symbol table and you can’t see the source code
Where can you compile the dll with the header file (or the exported static file lib)? You can also see the source code
I don’t know why it was stepped down
Can’t programmers nowadays distinguish between compilation and external services such as RPC calls?
As far as I know in BAT, most of the core code of T/B is C, because the real-time performance is better, and the main force of A family is Java.
1) Games, graphics and image rendering, imagine a game that is stuck for 50ms during play, and how painful it is to lose frames frequently. Thing
2) Real-time call, imagine that in the process of navigation, the vehicle speed is 100 kilometers, and the server side GCs, and the data is delayed by 100ms before sending, how painful it is.
If you know C, you will know what I mean.
The same goes for the encryption algorithm. Remote calls and services are only used in non-quasi-real-time situations. Those that are sensitive to data must be compiled with header files and libraries
1. Slightly larger companies will have a complete set of standardized permission control management. There are corresponding regulations for your level, what code you can download, and what libraries you can connect to.
2. You will be asked to sign confidentiality agreements and the like, right? Fire prevention, theft prevention and commercial espionage, the agreement is only part of it, the real secrets are in the hands of the Enterprise Development Department (similar department).
3. Regarding the module you mentioned in development, if it is of C series, it is the same as what the innocent classmate above said. I will give you a dll or lib and you can compile it and play with it yourself. In the case of Java, these modules will be encapsulated into services, or built into Saas or Paas. You can adjust them yourself. Generally, medium and large companies will use this type of development platform.
In our factory, general components are provided by the department responsible for components. What is provided to you is a compiled library, and you cannot access the code of the library.
If you find that there is a bug in the library or it is suspected that there is a bug and you cannot track it down, start a group and argue with the relevant departments.

How do you think about restricting employees from accessing the Internet to prevent code leaks? How should company IT be managed and structured to prevent code leaks?

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
