Relatively speaking, there is little information on the Internet, and few people write some detailed information about the Intranet penetration for the reference of their peers. Today, I am only going to give a general introduction to some Intranet knowledge.
First, under what circumstances will we meet the Intranet? If your goal is only limited to a small web, y
Enterprise Intranet security product selection Source: Network Author: Network Release Date: In recent years, security issues have become increasingly prominent in the internal network (terminal), and security events have frequently occurred.

Port ing principle
To connect a computer on the Intranet to the Internet, port ing is required.Port ing is divided into dynamic and staticDynamic port ing:A computer in the Intranet will send packets to the NAT gateway to access xinlang. the packet header includes the IP address, port, and local IP address and port of the other party (I .e. xinlang network, the NAT gateway will replace the local IP address

: Class C network address 192.168.0.1 and the corresponding default shielding value 255.255.255.0.Determine the destination address of the packetWe say that the "and" operation of shielding values and IP addresses is an internal process that determines whether a packet is passed to a host on a local or remote network. The corresponding procedure is this: when the TCP/IP initialization, the host's IP address and subnet mask value phase "and". Before the packet is sent, the destination address and
Find the private channel for the VPN Intranet to log on to the Internet. The author is located in a branch. There are two network lines, one is frame relay to the headquarters of the company, and the other is the normal ADSL bandwidth, only 512 K.

To protect Intranet security, I believe that firewall programs are installed on the Intranet of the vast majority of organizations. As a result, the idea of many network administrators attempting to remotely control the Intranet workstation on the internet is forcibly "contained. This is not the case. Because my local network is installed with a firewall and only
As an omnidirectional Security Network Technology in Intranet security, it uses a flexible key management solution to implement secure network communication between any two computer terminals in an open network.
1. Overview of omnidirectional Security Network Technology
Omni Directional Secure Network (ODSN) is a patented technology applied by Ming Dynasty Wanda. Omnidirectional security network technology uses flexible key management solutions to eff
The idea of Intranet penetration is derived from the idea of Trojan horse-bastion hosts are the easiest way to break through from the inside. A large website, a large company, a large target, and an external target, administrators will always do everything they can to strengthen prevention and fix vulnerabilities. It is almost impossible to use conventional methods.
The breakthrough of Intranet penetration
I once saw an article on the Internet that introduced a method for direct access to the Intranet. In fact, we only need to use the port ing tool to easily penetrate the Intranet. Port er is a tool like this. It is even more worth mentioning that it breaks away from the command line mode and provides a graphic interface operating environment.
I. Basic Ideas
