NAT analysis (intranet users access the server through domain names) 1. environment hypothesis: the private network address of the Intranet server is 192.168.2.20., port 80 of the server is mapped to port 80 of port 202.101.1.1, and the domain name www.sina.com is applied. The IP address of the Intranet PC is 192.168.2.2, now we configure the following command on
Sandbox), also known as Sandbox, is one of the most widely used technologies in the information security field in recent years. Google Chrome and MS Office2010 all use sandbox technology to improve their security. In the current IT field, Sandbox technology is widely used in the anti-virus software industry. For example, IT is used for virus experiments and various sandbox Security modes in user applications.
So what is sandbox technology? Simply put, sandbox is an "environment" that provides a
Duang~~~ has industry insiders, peanut shell intranet version will be online more than a router? If the message is true, then the user with the intranet IP address can be completely through the router settings to solve the remote access and management problems.Is the message true?According to small understanding, early in 2013, the peanut shell has been resolved in the
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. Data shows that manufacturing enterprises are also faced with problems such as data leakage, lack of confidentiality, and poor monitoring. How can we select a suitable Intran
The first description of our configuration file, are similar format, if the intranet is 192.168.0.3, the extranet is 123.123.123.123, the configuration file is as follows:
$db [' salver '] [' hostname '] = ' 192.168.0.3:3306 ';$db [' salver '] [' hostname '] = ' 123.123.123.123:3306 ';
This time is the external network is the state of the annotation. Walk is the intranet.The next idea, is a configuration file, copied out 2 points put to another plac

Intranet security management products must be intercepted with ARP Spoofing with caution. With the continuous popularity of Intranet security management products in the market, there are many product patterns with various ideas, but the trend of product homogeneity is obvious, in particular, for terminals to block illegal access to the Intranet, the method is gen

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
Immune NetworkThe solution is specialized in Intranet security management. It features both technical architecture, strategy, and feasibility to ensure stable operation of the network base. This is what all enterprise networks can use, the premise of application management. The immune network solution is not a separate product, but a complete set of components consisting of software and hardware, Intranet s
Development, try to obtain the score information in the university teaching system. The educational administration system of our school can only be accessed through the Intranet (only Intranet IP addresses ).

Working desktop has just been migrated to Ubuntu. It is a strange problem that Ubuntu can resolve the Internet normally, but it cannot resolve the Intranet domain name (the domain name ending with. local ). The following describes how to solve the problem. 1. Since I installed XP on Ubuntu, the Intranet domain name can be resolved through the NAT network link on XP. 2. You can use the dig command in Ubuntu
Almost all enterprises have paid more attention to network security. They have successively purchased firewalls and other devices to block security factors from the Internet. However, Intranet attacks and intrusions are still rampant. Facts have proved that the company's internal security factors are far more terrible than the external dangers.
Most enterprises pay attention to improving the border security of enterprise networks, but do not mention t
Terminal AuditThe real purpose is not to record all events that have occurred on the terminal for future query, but to collect evidence and analyze whether the implemented Intranet security management policies meet the security management requirements and promoteIntranet SecurityContinuous improvement.

SSH Intranet Port Forwarding combat
Guide
As you know, SSH is a secure transport protocol that is used more on the connection server. But in fact, in addition to this feature, its tunnel forwarding function is more attractive.

Firewalls and switches are still commonly used. So I studied how firewalls and switches implement Intranet/Internet isolation. Here I will share with you, hoping to help you. With the maturity and rapid development of network and Internet technologies, more and more enterprises and institutions have begun to set up networks to automate office work and share Internet information. However, security issues have also emerged. iMaxNetworks (memory network

Intranet is a major component of network applications, and its security has been paid more and more attention. According to incomplete statistics, 15% of the investment in building an intranet outside China is used to enhance the network security of the Intranet. Security vendors maintain a strong growth momentum in China's IT market. The proportion of investment
