Intranet SecurityIn the face of threats, firewall, anti-virus software, IPS, and other products are often ineffective. These products have been widely deployed in the enterprise network, but these products are mainly for Internet security protection.CAIt is a third-party trust institution that uses the PKI public key infrastructure technology to provide network identity authentication services, is responsible for issuing and managing digital certifica
What is port ing:
Port ing (NAT or napt) refers not to a port in the physical sense, but to a port in the TCP/IP protocol. It is a logical port. Port ing: if a computer on the Intranet needs to access the Internet, port ing is required. Port ing is divided into dynamic and static. dynamic port ing: if a computer in the Intranet needs to access xinlang, it will send packets to the NAT gateway, including the
Today, we will talk about how to use port ing without using the gateway to open the Intranet.
I. Prerequisites
A public IP address is required. Assume that we have a public IP Address: 210.210.21.21.
Ii. Tools used
1.lcx.exe
2. vdic
Iii. Methods
Method 1: Use lcx.exe for ing.
(1)we will upload lcx.exe to the public IP address, and execute lcx-listen Port 1 Port 2 in the DOS environment on the public IP Address
See lcx-listen 3030 for details.

This article focuses on the Intranet penetration elevation, which is not described for WEBSHELL.
Anyone who knows about intrusion penetration knows that after obtaining the webshell, the server must first find the vulnerability where the Elevation of Privilege is located.

What are Intranet, public network, NAT public network, and Intranet access methods of the Internet. Intranet access mode: the IP address obtained by the computer accessing the Internet is the reserved IP address on Inetnet. The reserved IP address can be in the following three forms: class A 10.0.0.0 8/GdIi4i Class B 172.16.0.0 -- 172.31.0.0 S {s si8} Class C 192
Company A accesses the Internet through ADSL, and the Intranet accesses the Internet through an ADSL Broadband Router sharing an ADSL cable.
With the development of Company A's business, the company needs to build A Web server for Internet access. The Web server mainly includes a company website, and is responsible for submitting daily orders and submitting business information of employees on business trips.
Add the company network after the Web se
For example, the domain name is free of charge when registering a peanut shell, because it is in the internal network, so the intranet version is used, set the intranet host, after Port ING, save, the Internet access address is automatically generated. How do I set an Internet access address without a port or port 80...
For example:
The domain name is free of charge when registering a peanut shell. because
One successful test of Sohu and sogou Intranet roaming0x01:
During the early tests on sohu network, a large number of sohu IP addresses were collected. For specific cases, refer to my previous cases. This is not the focus.
0x02:
Perform in-depth mining based on the collected ip addresses and obtain the following ip addresses:
220.181.61.204. Actually, it corresponds to the domain name app.m. TV .sohu.com (which was also confirmed later)
At that time,

In recent years, hackers through the Enterprise wireless network initiated by the enterprise Intranet infiltration incident frequency, in a vulnerability platform search found only 2015 years have occurred in dozens of well-known enterprises due to WiFi-related security issues caused by the intrusion of the intranet, the enterprise caused a very bad impact.By the year 2016, wireless network has become an im
The problem is this.
The existing two machines:Intranet: A server in the intranet 外网无法直接访问 .Internet: 外网可以访问该机器上的文件,服务器。同时,该机器可以访问intranet上面任何文件。 .
Because of historical reasons: the intranet built an intranet platform.
It is now open to external users and can be accessed directly.

Get Intranet IP address in nodejs, and nodejs get IP Address
Today, my colleague has a demand that the website corresponding to the web server in nodejs can support Intranet access. Later I found that I could modify the hostname attribute in express to my Intranet ip address. However, the problem is that all our machines automatically obtain the
Enable dual NICs to work on both the Intranet and Internet.Problem description: one computer has two NICs, one connected to the Intranet and the other connected to the Internet. The two NICs also need to work at the same time and do not need to be switched out when entering the Intranet, when connecting to the Internet, you do not need to unplug the
Department companies use dual-nic connections, but the Intranet segments are the same. For example:
Intranet Nic IP Address: IP address of the internal server of 192.168.1.0/24 Intranet Gateway: 192.168.1.254 where the ERP server 192.168.1.253
Internet Nic IP Address: 192.168.1.0/24 Internet access network segment Internet gateway: 192.168.1.1

ScenarioBecause the company's intranet has multiple servers whose http services need to be mapped to the company's Internet static IP address, if you use the routing Port ing, you can only map the port 80 of an intranet server to the Internet port 80, port 80 of other servers can only be mapped to non-Port 80 of the Internet. Non-Port 80 ing requires adding ports to the domain name during access, wh
Because the company intranet has more than one server HTTP service to map to the company's external network static IP, if the port map with the route to do, you can only one intranet server 80-port map to the extranet 80 ports, the other server 80 ports can only map to the outside of the network of 80 ports. Non-80-port mapping in the access time to the domain name plus port, more trouble. And the company p
There are many intranet users without public network IP, which can not access the NAS of intranet from external network. But if the day in the company did not complete, need to go home to complete or temporary transfer of the home of the NAS data, then the peanut stick can be used, the following is a peanut stick for remote penetration of the LAN limit to ask the case, share out to learn with you.

In the company, generally have their own intranet, but also have the connection of the outside network (can connect to the Internet), before the development of the company's intranet, and the next thing and then switch to the outside network, very inconvenient, so I would like to have been the method to make the intranet and the external network together. After s
The proxy server settings have many surprising relationships with the IE region.
The Local Intranet Zone is easy to use. It allows TCP/IP to allow servers on the other side of the earth to access the same server as the server on the lower floor .. on the other hand, the question "local" is left to the user or the network administrator to answer. it is easy to guess that when the machine is a local Intranet
