How to use "mathematical modeling-graph theory model" for automated intranet penetration testing Privilege escalation in the Active Directory domain is an important part of the struggle between most intruders and the Intranet administrator. Although obtaining the permissions of the domain or enterprise intranet administrator is not the ultimate goal of evaluation, it often makes the target to be tested easi

Errors are the properties of the software and cannot be changed. Testing is the inspection and evaluation of the quality of software products. The basic principles of software Testing: ① Software testing as early as possible, ② avoid checking their own programs, ③ test cases include reasonable input conditions and unreasonable input conditions; ④ test cases shoul

It can help you find out where your code is intentionally or unintentionally deviating from good design principles.

unit testing work.Programming language has been evolving and evolving, and its development has undergone a process from machine language to high-level language. The program designer should choose according to the requirements.In the early days of computer development, it was thought that programs were provided to machines rather than read by people. Therefore, it is sufficient to implement the correct logic so that the computer executes, and whether

Following these patterns (not exceeding their limits when using them) can help you implement most use cases safely and use volatile variables for better performance.Reference Learning You can refer to the original English text on the DeveloperWorks global site in this article.

cases provides better performance and scalability than locks. If you strictly follow the use of volatile conditions-that is, the variable is really independent of the other variables and its own previous values-in some cases you can use the volatile substitution synchronized to simplify the code. However, volatile the code used is often more error-prone than code that uses locks. The pattern described in this article covers some of the most common use cases that can be used volatile instead syn
