firewall is extended, and the firewall becomes a single fault point. Different from traditional packet switches, Web switches have the ability to maintain different TCP sessions for Ethernet and Gigabit Ethernet transmission. Because a firewall is a stateful device, all packets related to session creation flow through the same firewall. The Web switch intelligently maintains the status information of the data streams flowing through the firewall, thus ensuring that all data streams transmitted

This document describes how to configure the Cisco PIX Firewall through an instance. Before configuring the PIX Firewall, let's first introduce the physical features of the firewall. A firewall usually has at least three interfaces, but many early firewalls only have two interfaces. When a firewall with three interfaces is used, at least three networks are generated

via ssh, because you don't know what the IP address is next. So I thought of the peanut shell client in windows, and I could dynamically resolve the domain name. I quickly applied for a free Domain Name on the peanut shell website, but I didn't release the Linux client yet (now I have the source code to install it ), it seems vaguely that TP-link has a dynamic dns function. If you log on to the Dynamic DNS service provider, you can select a peanut shell, and enter the account password of the pe

DMZ is the abbreviation of "demilitarizedzone". It is called "isolation zone" in Chinese, or "non-military zone ". It is a buffer zone between a non-security system and a security system to solve the problem that the external network cannot access the internal network server after the firewall is installed, this buffer zone is located in a small network area between the enterprise's internal network and the external network. Some public server facilit

Firewalls typically have at least 3 interfaces, but many of the earlier firewalls have only 2 interfaces; when using aWith a 3-interface firewall, at least 3 networks are generated, as described below:Internal area (intranet).

other end. This enables the load balancing on several firewalls, so that the firewall can run in parallel, extending the performance of the firewall and eliminating the possibility of a firewall becoming a single point of failure. Unlike traditional packet switches, web switches have the ability to maintain different TCP sessions that are transmitted over Ethernet and Gigabit Ethernet rates. Because the firewall is a stateful (stateful) device, all packets associated with the establishment of t

Google.comCartoons.comDiscovery.com includes the option to configure the DMZ host. Enable SPISPI (full-state packet detection, also known as dynamic packet filtering) to prevent computer attacks by tracking more States of each conversation. It makes the traffic through the session consistent with the Protocol take effect. Whether the SPI is enabled or not, the router will always track the TCP connection status and ensure that each TCP packet in the c

Therefore, the firewall can run in parallel, the performance of the firewall is extended, and the firewall becomes a single fault point. Different from traditional packet switches, Web switches have the ability to maintain different TCP sessions for Ethernet and Gigabit Ethernet transmission. Because the firewall is a stateful device, all packets related to session creation must flow through t

In DMZ, save resources that require public access for Web servers such as the Internet. The Web switch must have a data flow filter function to determine which packets should be transmitted to DMZ and which should pass through the firewa

Figure 3: Virtual servers are opened to internal servers in the form of network service ports. As only limited ports are opened, high security can be achieved. Using DDNS with dynamic IP addresses to provide a public server with unspecified ports has low security requirements: Some applications do not have specific ports, and the server will decide the communication port with the client software as needed, in this case, you cannot use a virtual server. A typical example is video surveilla

If there is no DMZ, we will stick to the old method and use a separate cable isolation or AP virtual network to allow data to pass through a firewall before entering the Intranet, on

The wireless network technology is very mature, So how should we improve our network security for a large number of network users? If you ask any IT professional who is familiar with security about the use of wireless networks in an enterprise environment, they will tell you that Common AP security measures cannot really solve the problem. The broadcast nature of wireless communication, the increasingly advanced wireless listening tools, and the means to crack Wireless AP data transmission, all
