Whether it is to deploy a security gateway or other protection products, the ultimate goal is to prevent the enterprise from being compromised by network security. However, administrators should pay attention to Enterprise Intranet security protection while enhancing Internet protection. This article analyzes six internal network security threats through so
Question 1: Cross-origin penetration
In an intranet, the domain administrator permission of Domain a (a. AB .abc.com) has been obtained, and the entire domain has been controlled. Net view/domain: B shows that many machines exist in B domain (B. AB .abc.com). machines in the domain can be pinged to machines in the B domain and want to penetrate machines in the B domain across domains, obtain the domain administrator permission of Domain B.

After a lot of chickens have been put on the horse, the black friends may be thinking about how to use the loot in their hands. Some people like to spy on the privacy of others, some may use the Trojan horse keylogger to steal someone's QQ password, some people may want to steal someone's broadband Internet access account charge Q currency. But have you ever thought that these chickens in the intranet into a SOCKS5 server? In this way, we can use thes

The first step is to ensure that your intranet machine can smoothly connect to the Internet through the so-called proxy server. Here we will not talk much about it.
Let's look at this picture. As for how the proxy server with a public IP address (or the proxy gateway) connects to the Internet (also in the question mark), this is an ISP problem for individual users, I won't talk about it here.
This server has dual-nic, one set IP address is 61.134.36.5
Use Cases:
Network problems when using both wired and wireless Internet access in a notebook:
1. My environment is Intranet/Internet isolation.
2. Wired connection is an Intranet (LAN ).
3. Connect a wireless router that can access the Internet (generally Internet. 802.1.1

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

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.

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)

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.
