First of all, None-thread safe is not thread secure, it is not thread security security at the time of execution, thread safe is threading security, thread safety checks are performed to prevent new requirements from starting the CGI of the new thread Execution runs out of system resources. Then look at the two ways PHP executes: ISAPI and fastcgi. FastCGI execu

Improving system security involves many aspects, one of the important steps is to turn off unnecessary services. Although Microsoft Windows XP is not a network operating system, the default is that many of its services are open. For a sober Microsoft user, shutting down some unwanted services is an important aspect of security. Of course, each version of Windows offers a different service, so services that

Effectively managing user state in Web applications requires a delicate balance between performance, scalability, maintainability, and security. Security considerations are extra important when managing the user state stored on the client. One of my colleagues once said that processing client-side state data is like handing the ice cream to a 5-year-old: You can get the ice cream back, but you can't expect

It is said that when a PC (Windows system) on the Internet, if there is no anti-virus software firewall, then within 10 minutes will be the fall of the city of the virus. Why is it so? Because when you surf the Internet, maybe some sites will be implanted virus, a Trojan horse or something, the site's users as long as a landing, if there is no protection measures, then your machine will certainly be immediately captured. Of course, the site is not intentionally to hang virus and Trojan to the us

All operating systems have vulnerabilities, and none of them are absolutely secure. Any system connected to the Internet will be detected and may be intruded. Although the linux operating system is regarded as relatively secure, the operating system runs stably and quickly, but Linux itself has many hidden vulnerabilities. Today, the Internet is so popular that everyone is using Linux Original:Li chenguang All operating systems have vulnerabilities. None of them are absolutely secure. Any system

This article summarizes several major threats to the use of wireless Internet access and mobile security under the increasing popularity of 3G wireless networks: 1. Data truncation: Today, it is increasingly common for network hackers to intercept data through Wi-Fi. Fortunately, all products that currently support Wi-Fi authentication support AES-CCMP data encryption protocols. However, some early products are still used by users. These products only

1. thread security issues are caused by global variables and static variables. Thread security generally involves synchronized. If multiple threads are running simultaneously in the process where your code is located, these threads may run the code at the same time. If the result of each running is the same as that of a single thread, and the value of other variables is the same as expected, it is thread-s

Without secure server applications, secure client applications are not required. With OpenSSL, we can create secure server applications. This is not the case even though the document makes it look complicated. In this article, we will learn how to use the concepts learned in part 1 of this three-part series to build secure server applications. The first two sections of this series discuss how to use OpenSSL to create client applications. Part 1 discusses the use of OpenSSL to create basi

In the previous article, we introduced how to use class-dump-z to export class information of iOS apps, how to use cylinder to hook processes, execute runtime operations, and method swizzling, use gdb to analyze the app process. However, there may be better ways to do these things. It would be great to have a tool capable of doing all these things and better displaying the information. Snoop-it is such a tool. It allows us to perform runtime analysis and evaluate the black box

There is a default shared IPC $ in Win2k, and there are also ADMIN $ C $ d $ and so on, while IPC $ allows anonymous users (I .e. Unlogged users) to access

We know that the IIS server is now a widely used Web platform and it is relatively simple to build a Web site. However, the Web cannot run properly due to the IIS server intrusion or other reasons, which is very common. Therefore, IIS security has become a heart disease for many people. The IIS server can be used independently as a Web server or together with compatible tools, it can be used to establish Internet business, access and operate data fro

Rule 1: Never trust external data or input The first thing you must realize about WEB application security is that you should not trust external data. External data (outside) includes any data that is not directly entered by the programmer in the PHP code. Any data from any other source (such as GET variables, form POST, database, configuration files, session variables, or cookies) is untrusted until measures are taken to ensure
