How are you protecting your Windows server from malware? Whether you are talking about Active Directory domain controllers, Exchange or SQL Server-based systems, file servers, or even systems or terminal services that provide VPN access, what you are doing may be far from the best protection. In the past two years, I began to see Windows servers running various types of malware protection. But why is malwar

Web security practices (7) Introduction to web servers and common attack software Through the previous discussion, we have learned how to determine the type of web server. From this section, we will discuss web platform vulnerability attacks. The defect mentioned here is the defect of the server itself, not the defect caused by the Administrator's configuration. This defect can only be avoided by upgrading or patching. Of course, for different

As a network management unit, it is no stranger to FTP and other self-built storage services, and cloud storage, which has recently been developing in full swing, cannot turn a blind eye to it. after some trial and understanding, I think it is time to say goodbye to the self-built LAN storage.Self-built LAN storage is similar to FTP and network sharing. place a storage server in the LAN, enable ftp or network sharing, create a bunch of users and create directories for each user. After setting a

The following summarizes the common logic servers developed by small and medium teams. These servers are more role-oriented. Generally, one physical server serves multiple roles at the same time. Gateway (route) Usage: Public Accounts of the team access the Internet and firewalls. Common Software: the routing service provided by Windows server and the routing service of Linux. File Server

Anti-Black 15 tricks to protect the security of Enterprise Web Servers Here we provide 15 protection techniques to help IIS administrators protect Web servers at a very low cost.Of course, before talking about these techniques, we should first develop a set of security policies.The first step to protect Web servers is to ensure that the Network Administr

When two or more DHCP servers are scattered in the network, if you manage each DHCP server separately, it is not only heavy, but also difficult to manage, at this time, we need to be able to manage Multiple DHCP servers. We can use one of the DHCP servers as the Management Server to manage other DHCP servers. Therefor

Nowadays, many small and medium-sized enterprises are joining the ranks of deploying enterprise networks to improve their core competitiveness and quickly transfer internal and external information. To achieve centralized network management and reliable use of data information, servers have become an indispensable device. Many users still have vague definitions of servers. In fact, from my own point of view

This article is a summary of my experiences in terms of server network security. It is basic knowledge and suitable for entry-level server administrators, I hope I will not smile in front of technicians with old qualifications. First, we can analyze the malicious network behavior of network servers in two aspects: first, malicious attack behaviors, such as denial-of-service attacks and network viruses, these behaviors are intended to consume server re

An overview of four types of attacks against Linux operating system servers-Linux Enterprise applications-Linux server applications. For more information, see the following section. With the expansion of Linux enterprise applications, a large number of network servers use the Linux operating system. The security and performance of Linux servers have received incr

This article describes how to use Python to compile a super guide for HTTP servers. It also describes how to compile a web server based on the Python framework, recommended! For more information, see what is a network server first? In short, it is a network connection server built on a physical server, waiting for the client to send requests permanently. When the server receives the request, it generates a response and returns it to the client. Com

What is the difference between minicomputers and PC servers? From various performance evaluation indicators to the processing capability of a single CPU, minicomputers do not seem dominant. Why is it expensive?We can analyze the characteristics of performance, reliability, and scalability. For a single CPU, the Intel Xeon or AMD opteron used by PC servers is not inferior to the CPU performance used by minic

In our network construction, security has always been the top priority. Do you know the impact of illegal DHCP servers? So what kind of illegal DHCP server problems will happen? Here we will mainly explain how to solve the problem of illegal DHCP servers on the LAN. Recently, some computers in the company frequently fail to access the Internet. These computers automatically obtain IP addresses. However, aft

Shell script for automatic inspection of multiple servers Abstract: O M services for more than 20 (or more) servers in a project, the performance inspection of servers is performed every day to check whether the CPU, memory, and disk space of the servers are within the normal range. In this way, we do the same repetit

One of the most important components of any current TCP/IP network is the DNS server. A number of things a DNS server can accomplish, such as parsing an Internet URL into an IP address, resolving the host name on the local network, and providing the infrastructure on which the Windows Active Directory depends. Therefore, deploying a DNS server is not a very simple matter. To help some novice friends better understand the DNS server, this article discusses some of the experience and common sense

Source: http://blog.csdn.net/AppleBBS/ ReprintedA few days ago, I suddenly wanted to find a Web server with better performance than Apache. I remember that I was in a large BBS (which has been forcibly disabled by relevant departments) we can see that they are running a 64-bit open-source WebServer on the AMD64 server, which is three times faster than Apache. So I went to Google to find it. Unfortunately, I cannot remember the name of the WebServer at all.Unexpectedly, I saw such an article, whi
