What are the three eras of information network security?

The three eras of information network security are the host era, the private network era and the multi-network era. A private network is a channel cooperation network between content providers and operators. It refers to a communication network built within some industries, departments or units to meet their needs for organizational management, safe production, dispatching and command, etc. Multi-network integration is to use only one set of TCP/IP network equipment and integrate multiple subsystems of the community into one network through a unified TCP/IP transmission mode.

The three eras of information network security are the host era, the private network era and the multi-network era.

Network security can actually refer to the security of computer communication networks. Computer communication network is a system that interconnects several computers with independent functions through communication equipment and transmission media, and with the support of communication software, realizes the transmission and exchange of information between computers. Computer network refers to a system that uses communication means to connect several independent computer systems, terminal equipment and data equipment that are relatively scattered geographically for the purpose of sharing resources, and exchanges data under the control of protocols.

The basic meaning of safety: objectively there is no threat and subjectively there is no fear. That is, the object does not worry about its normal state being affected. Network security can be defined as: a network system is free from any threats and infringements and can normally realize resource sharing functions. In order for the network to realize the resource sharing function normally, we must first ensure that the network hardware and software can operate normally, and then ensure the security of data information exchange. As can be seen from the previous two sections, the abuse of resource sharing has led to network security problems. Therefore, the technical approach to network security is to implement restricted sharing.

Private network communication

Private network is the content provider and operator Channel cooperation network

Private network communication refers to emergency communications, command and dispatch, daily work communications and other services provided for government and public security, public utilities, industry and commerce, etc. It refers to the communication network built within some industries, departments or units to meet their needs for organizational management, safety production, dispatching and command, etc.

Multiple networks into one

Multiple networks into one simply means using only one set of TCP/IP network equipment and using a unified TCP/IP transmission mode. Integrate multiple subsystems of the community such as building video intercom, access control card, home alarm, perimeter anti-theft, closed-circuit surveillance, community background music, patrol, vehicle management, information release, property management, VOD on demand, IPTV, etc. into one In the network.

With the development of network technology and the acceleration of the popularity of optical fiber, the technical problem of "multi-network integration" has been effectively solved. On the basis of this technology, in order to extend the longevity of the system, the National Housing and Living Environment Project The research center has put forward the concept of intelligent residential health system, that is, the system is healthy and must serve people's healthy living.

The content of a healthy system mainly includes that system resource consumption can be reduced, system functions can be extended and expanded, the system can be independently operated and maintained relying on the network, system equipment can self-check faults and repair itself, and the system can establish remote control based on GIS Maintenance system; a healthy system serves people's healthy living, including personal safety that can be checked online, household appliances that can be controlled, business services that can be interacted with, information services that can be personal, and financial services that can be provided without leaving home, etc.

We will not deny the great contribution that the independent networking method of each system has made to the intelligent construction of the community in the past, nor will we forget the convenience it once brought to the intelligent management of our community. However, with the advent of technology, With the advancement of technology, especially the rapid development of digital communication technology, and the continuous improvement of market demand orientation, digital devices with high stability, high scalability, and high cost performance are increasingly favored by people. Next, we will start with the characteristics of the "Longwang Ruicheng. "Multiple networks into one" system is an inevitable trend of development.

Ⅰ. Save investment and reduce pipeline construction

The benefit of "multi-network integration" to investors is that there is no need to build multiple pipelines, and only one network is needed for the entire community. , eliminating the need for the construction of weak current pipelines for eight networks (visual intercom/access control/vehicle management/video surveillance/PTZ control/property management/background music/perimeter anti-theft) in one community. This benefit saves investment and reduces future maintenance costs and complexity. From the perspective of construction lines, due to the "multi-network integration", the use of copper wires has been greatly reduced. According to the results of later work and material measurements, the savings have reached more than 60%. From the perspective of cost, comprehensive statistical results of several cases (including construction and installation costs related to intelligent construction) show that with the same functions, the comprehensive investment cost of a multi-network integration system saves about 10% of investment compared with traditional solutions

Ⅱ. Save computer room investment and increase income

Another benefit of "multiple networks in one" is that there is no requirement for the location of the computer room. Traditionally designed intelligent systems often choose a central location, called the "central computer room", in order to have the shortest route connecting everywhere. For projects developed in phases, a computer room is set up in almost every phase, which is a serious waste of land resources! After adopting the network solution of multi-network integration, the "central computer room" means central management and no longer specifically refers to the geographical location. The location can be determined according to the actual situation, and the optical fiber network can be reached. If it is a villa or a high-rise community, our building intercom is particularly advantageous! Set up IP and make calls at will!

Ⅲ. Convenient upgrade

"Multiple networks into one" in investment Without changing the situation, the multi-network integration system will provide more functions and room for upgrades to achieve the goal of a healthy intelligent system. Judging from the operation and maintenance cost results, after three to five years of operation, although the terminal equipment has been damaged, the network system has remained smooth. After the terminal equipment is replaced, the system maintenance can be maintained for a long time.

IV. The influence and competitiveness of the fully digital community improvement project

The "multi-network-in-one" solution can effectively To improve the level of intelligent community management, all kinds of information are promptly summarized in the management center to ensure that meticulous and comprehensive property services are quickly in place; at the same time, we have a group of international and domestic security professional management, sales, and technical elites to provide you with high-quality project support services. More importantly, it exceeds the service standards of other companies in the industry and can provide you with immediate and professional services, bringing you closer to the target group and enhancing the brand image of investors. For real estate projects, the future competition will be information-based competition. In the past, a community intelligent system needed to build seven networks, which required a lot of wires, which was expensive, labor-intensive and time-consuming. At the same time, the system standards of each security equipment were different. Unification, all investments will be returned to zero during transformation, resulting in a waste of resources, and in severe cases, it cannot be transformed.

Ⅴ. Select high-quality products to reflect the culture of the investor

"Aberdeen World" high-tech product development and production, each link has a complete supervision and testing system to ensure the quality of marketed products Ultra-low failure rate and high-quality products reduce the cost of system maintenance. They also reflect the culture of investment and the strong sense of team responsibility for product excellence.

VI. Leading technology embodies humanistic care

The "multi-network-in-one" solution has become a model of intelligent digital system for residential areas in the industry with its system integration and leading technology. High-definition can be easily realized in this community. Video on demand, information release, real-time Internet data exchange, etc. enrich the lives of community members and reflect the humanistic care of investors.

VII, boundless family ties, unlimited communication

"Multiple networks into one "The solution adopts a unique data exchange processing method to realize information exchange within the community and wide area network (IP telephone), allowing you to transcend the constraints of other intelligent system spaces and facilitate the enhancement of feelings among community members.

Ⅷ . Target customer (owner) group needs

Owners’ requirements for the living environment of the community generally include the following aspects: first, convenience; second, safety; third, community management services must be timely, which will inevitably have an impact on the community. Intelligent systems have higher and more special requirements.
