This article focuses on the direction of Enterprise Intranet security planning. The computer has been facing the public for just over 40 years. The world economy, science and technology and other indicators have developed rapidly. The cultivation of professionals is relatively slow. These problems have emerged and become increasingly serious.
Enterprise Intranet security planning first, to do its best

For small and medium-sized enterprise users, viruses, hackers, and malicious attacks are no longer "legends". In the complex and changing network security situation at present, the network system carries the foundation of enterprise operation. The FBI and CSI conducted a special network security survey on 484 companies. The survey results show that more than 85% of security threats come from within the company. In terms of the loss amount, the loss caused by leaks of internal personnel is 16 tim
Question 1: Cross-origin penetrationIn 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.Can I ask the
I have previously shared with you some personal views on the two cutting-edge technologies that may be used in the Intranet security field (sandbox that has not been widely used, and access control that has become more mature, today, I will discuss with you a topic that may be more cutting-edge for domestic enterprises: the threat that mobile device applications pose to Intranet security.

First, explain the concepts of "intranet" and "Internet:
Intranet: the IP addresses of each computer in a LAN, for example, a School LAN, are mutually exclusive within the LAN. However, the Intranet IP addresses in the two local networks can be the same.
Internet: the Internet. The IP address is the only IP address that connects to the Internet through a server o

On a Linux server or on a Windows server, You can use this command to create a Web service that can be accessed quickly in the intranet, as long as you install Python. In the directory where you want to build the Web service, use the python3.x built-in method:Python-m Http.server 80008000 is the port number of the link, so that the local in the browser can access the directory through http://localhost:8000, and the LAN, such as other computers, can b
Problem Description:
1, the PIX placed in a fixed IP environment (external network for fixed IP), and set the correct ACL allow ICMP release, this case intranet can be normal Internet access can also ping the extranet.
2, and then put the PIX in the ADSL environment (with PIX to dial), ACL or before the same, PIX under the intranet computer can only surf the internet, can not ping the extranet.
Solution:
One, the internal LAN all use the private address on the network, under the normal circumstances, the internal computer in the direct use route external access, will because the computer uses is the Internet reservation address, but is filtered by the router, thus causes cannot access the Internet resources, The solution to this problem is to use the NAT address translation function provided by the routing operating system to convert the private address of I

It is very convenient to develop MIS system on internet/intranet based on ASP technology, first of all, it borrows ADO technology and concept, and accesses database through ODBC, and achieves full flexibility and multi-platform, in addition, because of ASP using VBS and JS scripting language, It also ensures that most developers quickly enter the development process and reduce the learning process.
However, because the ASP is based on the Internet/
Often the company's development environment will be arranged in the intranet, and then there will be a common server for everyone to develop, test, so often there will be SSH connection server, or local MySQL client connection server needs, I personally experienced the company often occurs ssh/ MySQL connection to the public server is very slow, because the SSH service and MySQL service by default will be at the time of the DNS reverse parsing process
