codesonar vs coverity

When we try to synchronized a collection, coverity scans with a hint of bad choice of lock object. Refer to the following code: public class Test {public static void main (string[] args) throws Exception {integer in = new Integer (123 29); Thread1 thread1 = new Thread1 (in); If the lock object is a map above, you can modify the success Thread2 thread2 = new Thread2 (in); New Thread (Thread1). Start (); New Thread (

are source code weakness analyzers, source code security analyzers, static application security testing, static analysis code scanners, and code weakness analysis tools. Each source code analysis tool uses the type matching method to find vulnerabilities. There are many reports to evaluate these tools. However, this vulnerability was not found using static analysis tools in the past: 1. Coverity: Coverity

The Python code has the lowest density of bugs, just 0.005 per thousand lines of code, according to the Coverity company, which provides development testing services. Industry-accepted standards are 1 per thousand lines of code defects, code defect density less than 1.0, which is considered high-quality code. According to the 2012 Open source Code Scan report, the average defect density of open source code is 0.69, while Python is 0.005.

the "Google languages", many people will notice this, thus there will be "influence ". This was indeed what happened later. After I left, Grok began to provide services to many projects through APIS, including CodeSearch. The salary Google gave me was not enough to afford such software. You can refer to the price of "static analysis" software such as CodeSonar, which is basically my three-month salary. Because I want to find something to offer at sch

intrusion is to inject code where it is not. Relro the appearance of this segment is to make a part of the area into read-only. For example, Ctors, DTORS,.JCR and so on are often placed in this section. Unlike the stack's not executable attribute is guaranteed to implement on the kernel side, this technology's read-only setting exists on the user side, is the compiler and the loader completes together.

security can not just rely on the compilation.A core principle of security is to render as small a target as possible. CPython solves these problems with simple, stable, and easy-to-audit virtual machines. In fact, in a recent analysis of Coverity software, CPython has received the highest quality evaluation.Python also has a wide range of open source, industry-standard security libraries. Combining Hashlib,pycrypto and OpenSSL with Pyopenssl, some p

Open source C + + static analysis tools Java has some very good, open source static analysis tools such as FindBugs, Checkstyle, and PMD. These tools are easy to use, useful for development, can run on a variety of operating systems and are free of charge.The commercial level of C + + static analysis tool products are klocwork, Gimpel and Coverity. Although these products are excellent, they are expensive and unsuitable for most students.Another appro

GNU/Linux security baseline and Reinforcement "With the popularity of GNU/Linux in IT infrastructure in various industries, security issues have become the focus of attention. GNU/Linux is mainly built by the GNU core (compiler GCC, C library Glibc, etc.) and Linux kernel combination, in the environment where free open source software dominates the basic platform, many people think that open source must be safe, this is an incorrect idea, coverity re

satisfactory. Static analysis Static analysis does not require you to run the code, you do not have to write a test case to find out some of the code is not standardized, or some flaws exist. This is a very effective way to find a problem, but you need to have a tool that doesn't have too many false positives. Common static analysis tools for C # are coverity,cat,net,visual Studio Code analyses. Dynamic analysis When you run the code, the dynamic ana

applications. The following are some tools for this situation. Here, there are two technologies available: static code analysis and runtime analysis. Many static code analysis tools are available in the market. Such as Lattix, Structure101, Coverity, nWire, and IntelliJ's DSM. For changed classes, the above tools can identify the set of classes dependent on the class. Developers need to "guess" the use cases that may have an impact based on the infor

not produce very quickly. The most critical reason is that this method is not very fast, so he uses his own method to manage the memory. Q: Can I give an example to illustrate whether there are other factors besides the speed? Wu Shi: If the OS method is used, because each request for memory may be the same as the Npower of OS2, the minimum amount of memory fragments is generated, and the least amount of memory fragments is generated when heap management is unavailable. If it is not the second

does not provide such an improvement. Advanced languages give us the ability to abstract and build projects at a higher level. Abstraction is the foundation of the future. We can no longer worry about bit and byte because the cost is too high. Whether you like it or not, the Windows API does provide a lot of resources for desktop developers. Tools of various styles can abstract the details at the bottom layer. The first Fortran compiler, in today's standards, is simply so ridiculous that it gav
