security requirements can be mixed in the unit testing, integration testing, and system testing. However, for software with high security requirements, special security testing must be performed to prevent and identify software security issues before they are damaged.Securitytesting refers to the process of verifying

Write an article here summarizing these types of questions and their corresponding solutions. Convenient for other project group reference.

Three questions: Linux operating system security hardening1. Why do I need to secure the reinforcement? safety reinforcement is self-evident. Here I have the operating system and Maslow's hierarchy of needs to make an analogy, if there is inappropriate, but also please advise. Like people, the operating system also has its own physiological needs, for human physiological needs are nothing but eating and dri

It can concurrently run the same method multiple times to see if the expected performance targets can be achieved. For example, the following code uses the Ntime framework to start 2 threads and execute the MyTest method multiple times i

In addition, some role authorization issues are also involved in the code!Today's topic is as fo

undeniable that tools that automatically detect code security vulnerabilities can also help to quickly develop secure applications. So far, tools commonly used by developers can only cover specific aspects of functional testing, such as performance testing and BUG/fault point detection. Manual check code has many inherent limitations and requires developers to have rich code

Manual check code has many inherent limitations and requires developers to have rich code security experience. Therefore, for writing high-quality applications, application-Oriented

asynchronously. This means that the thread needs to be queued for processing.When using the same section, we should try to narrow the scope of the synchronization code as much as possible. Do not use synchronization directly in the sevice method and response method, which will seriously affect the performance. 2. Attribute thread security: attributes in the servletcontext, httpsession, and servletrequest

immediately finish "read/change/write" All the work, then a continue to write work, the result is a operation has no performance! Intruders may use this process sequence to rewrite some important files to get into the system, so programmers need to pay attention to the sequence of file operations and locking problems. 　　2. Improper system Configuration Insufficient default configuration: Many systems have default
