administrator cannot establish a document to support their security work. As a result, a conflict occurs.By marking security policies for the security level and availability of web servers, network administrators can easily deploy various software tools on different operating systems.Microsoft's products have always been the target of all attacks. Therefore, IIS

supports their security work, so the conflict occurs. By labeling Web server security levels and availability security policies, network administrators will be able to easily deploy various software tools on different operating systems. IIS Security Tips Microsoft's products have always been a target, so IIS servers are particularly vulnerable to attackers.

application are still on different application servers. This is mainly to facilitate employees from outside the enterprise access to the OA system. The advantage is that when a Web service suffers an attack that is not available, most employees are unable to access the OA system from outside the enterprise, without affecting the normal access of employees within

What is fastcgi and php-fpm in PHP? Php Recently in the study and study of PHP performance knowledge, see the factcgi and php-fpm, found that I am a little less understanding of them, can be said to be almost ignorant, it is quite scary to think about. decided to study carefully about this knowledge. The following articles are referenced and studied:1. Introduction, comparison, and performance data of mod_php and mod_fastcgi and PHP-FPM2. Actual combat nginx_ replaced In order to step by step

A hidden threat to * nix WEB Servers From: https://www.virusbtn.com/virusbulletin/archive/2014/07/vb201407-Mayhem0x01 Introduction Websites and even servers are becoming more and more popular. This infection is usually used to intercept communication, black hat SEO, leeching downloads, and so on. In most cases, such malware is composed of relatively simple PHP sc

soon to graduate, but also to start looking for a job, the university wrote so many code, but not a good summary of the commonly used concept is a pity amount, through this blog record my most commonly used knowledge of the good. When it comes to Web servers, there are a lot of articles are introduced very well, before I saw a very good, to my help is very big, but now can not find the original text, see th

Start with HTTP CompressionHTTP compression is used to transfer compressed text content between web servers and browsers. HTTP compression adopts common CompressionAlgorithmSuch as gzip to

Ubuntu. Each attacker attempts to break through the identity of a limited user and exploit a vulnerability in the kernel to obtain the root access permission. Using grsecurityhttp: // olex.openlogic.com/packages/grsecurity) to patch the kernel ensures that you are protected and can even prevent zero-day vulnerabilities. In addition, Ksplicehttp: // www.ksplice.com/) ensures that you promptly update all the kernel versions to minimize security risks. ◆ Mandatory access control MAC ).In a normal

one-way synchronization occurs, login to the server may fail, and other servers will not be able to provide services. of course, you can also consider the problem of two-way synchronization. 　　 3. using NFS to share Session data In fact, this solution is similar to the following Mysql solution, but the storage method is different. Generally, a public Network File Server is used as a shared Server. when all

Web Server Get startedBefore Apache, we should familiarize ourselves with the Web server, because Apache is also a type of Web server. The web system consists of a client (browser) and a server. The web system architecture is also called the B/S architecture. The most

Background:Our server environment, is the ESX server, which ran dozens of virtual servers. Most of them are virtual Windows servers, and then each application will have several app servers and then install WebSphere to build cluster to support the Web server, both IBM HTTP server and IIS.The environment is like this, t

PHP allows multiple web servers to share SESSION data (write session data to mysql database) I. websites with a slightly larger problem generally have several servers, each of which runs modules with different functions, different second-level domain names are used, while th

network communication and filters outbound HTTP (port 80) traffic. If the client request is buffered locally, the buffered data is directly sent to the user. If there is no buffer locally, the request is sent to the remote web server. The remaining operations are identical to the standard proxy server. For Linux operating systems, transparent proxy is implemented using Iptables or Ipchains. Because you do not need to make any settings on the browser,

, running in a separate common process with other applications (medium), or running (high) in separate processes that are different from other processes. 2. Redirect to URL These properties appear when you select Redirect to URL. Customers will be sent to The exact URL entered above Redirect the virtual directory to the destination URL without adding the original URL Any other part of it. Use this option to redirect the entire virtual directory to a

Preface: After a brief introduction to the network layer protocol and HTTP protocol in the previous topic, I believe that you have a general understanding of the protocols in the network. This topic will define a Web server for the HTTP protocol, you can view the desired webpage by entering a URL in the browser. In this process, the browser is only a client.Program) Send user requests to the server through the HTTP protocol. The server receives the

this point the user will see the word "End of message" in the browser. The whole process is over.3.CGI IntroductionIntroduction to CGI:=====================First, the concept: Public Gateway Interface CGI (Common gatewayinterface) is one of the most important technologies in WWW technology, which has irreplaceable important position. CGI is an interface standard between an external application (CGI program) and a Web server, and is a discipline for p

present, another kind of webserver has emerged, which is superior in terms of concurrency, called asynchronous servers Asynchronous Server. The most famous ones are nginx and Lighttpd. The so-called Asynchronous Server is the event-driven in the event-driven mode. In addition to the user's concurrent requests, only one or several threads are required. Therefore, system resources are very small. These are also called lightweight
