With the rapid popularization of Internet applications, the relationship between people and networks has become increasingly close. However, due to the openness and interconnectivity of the Internet, there are many insecure factors in the network, malicious software attacks, and hacking behavior seriously threaten people's interests and security. Therefore, we need a solution that can protect computers agai

We know that the WEB server can be divided into three layers, and any layer of the server may cause security threats to the entire website. Therefore, when deploying a WEB server security policy, enterprise security management personnel should comprehensively build an Enterprise Web security protection

For most enterprise LAN, routers have become one of the most important security devices in use. Generally, most networks have a primary access point. This is the "virtual border router" that is usually used with a dedicated firewall ". After proper configuration, the border router can block almost all the most stubborn bad elements out of the network. If you want to, this type of router also allows good peo

Network security is a never-ending task that requires continuous vigilance. Protecting your wireless network is a particularly tricky task, because unauthorized users are invisible and can sneak into your network without being discovered. To make your wireless LAN more secure, it is important to discover and fix new wi

In the war, a line of defense without depth will collapse after a single point of breakthrough. However, when multiple lines of defense are built, the lack of timely and intelligent coordination between lines of defense may compromise the attack defense efficiency. Because the soldiers in various defense lines fight independently, they cannot organize effective counterattack after a line of defense is broken, Network

The switch occupies an important position in the enterprise network, which is usually the core of the whole network. In this era of hacker intrusion and virus-ridden network, as the core of the switch is also taken for granted a part of the responsibility of network security

With the development of China's routing industry, the router technology is constantly updated and upgraded. Compared with IPv4, IPV6 has many advantages. First, IPV6 solves the shortage of IP addresses. Secondly, IPV6 greatly improves many imperfections in the IPv4 protocol. The most significant one is to integrate IPSec into the Protocol. From then on, IPSec will no longer exist separately, but as an inherent part of the IPV6 protocol, it runs through various fields of IPV6. Of course, the larg

VroAfter proper configuration, the edge router can block almost all the most stubborn bad elements out of the network. If you want to, this type of router also allows good people to access the network. However, a vro without proper configuration is better than no security measures at all. In the following guide, we will look at how you can protectNetwork

Security mechanism of IPv6 The security mechanism of IPv6 is mainly manifested in the following aspects: (1) Placing the header authentication and security information package which is independent of the IPv4 protocol family as IPv6 into the IPv6 Basic protocol, which provides the guarantee for the IPv6 network to rea

This article describes in detail how to improve network security for enterprise wireless networks? The following article gives us a detailed introduction, hoping to help you. Generally, the devices used by hackers cannot reach the wireless network, and they cannot break into the network. Some routers allow you to contr

How many technologies can be hidden in the security of wireless networks? So is hiding the SSID really effective for our use? The following article will explain it to us. Wireless network security has always been a hidden danger. Most home users think that hiding the SSID wireless network ID can greatly improve

With the development of network technology, wireless network security has become more and more important. From what perspectives should we set up? Next we will introduce it to you. Why should I disable the network line for wireless network application

skills here are also very useful for IIS administrators with a strong budget. First, develop a set of security policies The first step to protect Web servers is to ensure that the Network Administrator understands every rule in the security policy. If the company's top management does not regard server security as an

Now the enterprise network not only has fixed line LAN, also has wireless LAN. In fact, both the wired network and wireless network are also facing security problems. Once a hacker said: As long as the default network settings have not been modified, it is a false wall, you

In the face of wireless network security problems, we often do not know how to solve them. How should we strengthen network security management? I believe you will understand this article. Compared with the traditional wired network, the wired

Computer popularization, broadband prevalence, now many friends online time is very long, so the security of the system has become "the most important." Fortunately, many security sites now provide online detection services, can be a good help us to detect the existence of their own computer vulnerabilities and security risks, so that timely and effective solutio

Each layer of communication has its own unique security problems. Communication connections at the second protocol layer of the data link layer are relatively weak in terms of security. Network security issues should be addressed at multiple protocol layers for different vulnerabilities. In this article, we will focus

The primary responsibility of the enterprise network administrator is to ensure the security of the Intranet. In the Intranet, route switching, especially for the core layer, is the highest security requirement, as a network administrator of small and medium-sized enterprises, how can we ensure the
