Background Analysis of Intranet security implementation
As the Spring Festival is approaching, white-collar workers and blue-collar workers will return home. Newly Decorated and cleaned apartments and rental housing have also begun to meet the post-holiday occupancy peak with a brand new look and a comfortable housing environment.
Many rental houses are also considering introducing or upgrading networks at this time. vrouters are the door to network a
User features of Intranet Security Cases
Enterprise sensitive data with design drawings as the core is highly dependent on networks and various information processing terminals in the production and dissemination processes, data is widely transferred between design and production departments (including stamping, welding, painting, and Assembly;
The information level of terminal operators varies greatly because of professional differences among employe
The existence of mobile devices not only changes the way individuals live, GigaOm's latest report shows that 38% of enterprises interviewed have applied mobile devices to different degrees in IT, 43% of enterprises surveyed plan to introduce mobile device applications within one year, while 500 of fortune 65% enterprises have deployed I-Pad to varying degrees. Users are used to using Blackberry to send and receive emails, using tablets for demonstration, using mobile devices to remotely access t
It is impossible for a dual-nic computer to have two gateways, because the default gateway can only be one. Install two NICs for the UbuntuLinux server and set different ip addresses and gateways (intranet and Internet) respectively. The Internet can be accessed through the Internet Nic, and the Intranet can be accessed through the Intranet Nic, it seems very eas
After obtaining the linux permission. First, collect information about port information. Check whether there is a connection such as 389 .. (If you have port 389, you may have an ldap configuration file or a DC Password. I will have it.) You can also see some Intranet IP addresses on the port... Then collect the Intranet IP address segments .. Arp-a also shows some Intr
I have been busy with UDP socket communication over the past few days. After a few days, I have finally achieved some success ....
If you do not understand the differences between the Intranet and the Internet, and do not know the LAN and WAN, you should first familiarize yourself with the program. My current situation is that the client is on an intranet and wants to connect to an internet server. After re

The following are the implementation Notes for an Rmi project:
Environment: Firewall (XX guardian) Internet IP Address: x. x. x.135 port: 8400/8500 Intranet IP Address: x. x. x.90 port: 8400/8500
The Intranet and Internet IP addresses and ports are mapped to each other. (the Internet IP addresses are configured on the fire
Some time ago I made another communication software in Java-shanzhai zookeeper. Generally, this simple chat software is called a LAN chat tool, so can it implement Internet access to the Intranet for communication? This problem has been lingering for a long time in my mind.
In the past, two simple clients used to communicate directly without passing through the server. Therefore, it is really hard to think about how to access machines in the other
---restore content starts---In the public network environment, to realize the remote access by domain name housekeeper management software, server or store video surveillance, etc., can be used dynamic domain name resolution software. But now IPV4 resources exhausted, the Great Wall broadband and other broadband operators to the user assigned to the network IP address. How does the intranet support it?Home network belongs to the
Modern office, each enterprise will establish its own internal LAN, and set up a server to store and share the day-to-day work of the various types of data required, many employees will also share some of their own computer data, so that other users of the local area network access and use, this way is to save data delivery time, Improve the efficiency of everyone, it can be said, very convenient. However, the resulting information security, network security issues are gradually exposed, we have
The Oracle database is one of the most applied databases. General Project Application. Deploying Oracle in the Intranet, intranet calls, and operations can only be done on the intranet.Suppose the Oracle host or local area network does not have a fixed public IP and wants to access Oracle on the outside network. It is necessary to solve the problem of dynamic IP or no public network IP. Corresponding applic
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
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.
I. Leave the terminal audit misunderstanding
An important feature of terminal audit is to backtrack historical events in the past ". For example, Can y
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.
If the Linux server between the two intranet needs to log in with each other, or need to access a port on the i
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

Enterprise Intranet security status quo and problems
In modern enterprise informatization construction, the network architecture and scale will be constantly changing according to the enterprise's own business needs. At the same time as the completion of the basic network architecture, various application systems have also begun to be built. The network architecture and application systems are inseparable.
