Analysis of the application of cloud storage in the security field in 2013

    Cloud computing has not been used for a long time. In just a few years, it has been widely used in the Internet, mobile Internet and other fields due to its massive storage capacity, data storage security and data sharing. It is gradually moving towards cross-border fields, and the security industry is one of them.

    However, the promotion of cloud storage technology in the security field is still subject to restrictions. For example, the amount of data consumed by the cloud is very large, and the conditions for data centralization are not yet met. The application of cloud storage in the security field will still take a long time, but with the current development of the Internet, the prospects for cloud security will be better. With the deepening of smart city construction, users' demand for video storage data to be linked and shared with each other is increasing, and the existing storage technology cannot meet this security demand well. The application of cloud storage technology in the security field has emerged with its inherent advantages.

   Introduction of cloud security and cloud monitoring concepts

    Cloud security is based on the Internet of Things model and uses cloud storage technology to meet the needs of modern security. The specific implementation refers to the use of cluster applications, grid technology, distributed file systems and other functions to bring together video surveillance, access control, RFID radio frequency identification, intrusion alarm, fire alarm, SMS alarm, GPS satellite positioning and other technologies through cloud security to work together, exchange information and communicate, and complete intelligent identification, positioning, tracking and monitoring security management. Users can conduct 24-hour seamless remote supervision through C/S, B/S and the client end of mobile devices.

    "Cloud monitoring" in the security field refers to making full use of technical concepts such as cloud computing, cloud storage, data centers, and business intelligence in the development process of the IT industry, optimizing the design and development of data center architecture and technology for multimedia services such as monitoring, and through the practice of large-scale security networking, making the overall architecture robust, scalable, operational, and standardized, achieving increasing centralization of video data and further realizing the intelligence and informatization of data, making management and operation more efficient and simple, and ultimately achieving a continuous reduction in total TCO costs, which has promoted the continuous evolution and development of the monitoring industry as a whole into the IT cloud computing era.

    Cloud monitoring has become a hot topic in the security industry in recent years. The industry mostly discusses it from the concept of smart cities, and unanimously equates security cloud with the stage of IT's cloud computing video surveillance industry - resource virtualization and cloud services. The concept of cloud monitoring in the security field is also constantly being improved.

    Advantages and characteristics of cloud storage technology in the security field

    The application characteristics of cloud storage technology in the security field include: monitoring cloud storage will make greater use of video surveillance hosting services to provide customers with private cloud services for smaller-scale deployments, such as homes and shops; security cloud services will be customized by enterprises, and cloud service providers will provide the necessary infrastructure, services, software and hardware resources; the data center model will be introduced and gradually become the mainstream form of the security industry.

   Cloud storage has the following advantages:

    Storage management can be automated and intelligent. All storage resources are integrated together, and customers see a single storage space. Cloud storage can achieve economies of scale and elastic expansion, reduce operating costs, and avoid resource waste. It improves storage efficiency and solves the waste of storage space through virtualization technology. It can automatically reallocate data, improve the utilization of storage space, and also has load balancing and fault redundancy functions.

    Problems in the application of cloud storage technology in the security field

    Due to the characteristics of the security video surveillance business itself, there will be differences between surveillance cloud storage and the existing Internet cloud computing model. For example, security users tend to store video information locally, government video surveillance applications are more sensitive, there are privacy issues for video information, and video surveillance consumes a lot of network bandwidth.

    The application prospects of cloud storage in the security field

    The construction of safe cities and smart cities has prompted the application of security cloud storage technology. One of the major requirements of smart cities is to link and share video storage data with each other. For example, when tracking crimes, storage data from multiple fields such as public security, transportation, and civil industries can be shared, and this sharing has the characteristics of cloud storage. Traditional storage technology cannot meet the needs of social development, and the application of cloud storage in the security field has become inevitable.

    At present, several safe cities in China have made attempts. In the future, with the help of the exemplary role of the pilot projects and the large-scale application of smart cities, we will gather the power of the people and promote the improvement of relevant application standards. It is believed that the application of cloud storage in the security field can be promoted more quickly.

    In terms of current application needs, some industry users, such as oil, coal, gold, etc., need to aggregate all data for analysis and processing. This demand can be met by building a private cloud; while some users want to build the entire monitoring system, but do not want to spend too much energy, and hope that all data in the entire city can be shared, so that they can be linked in time when accidents occur. This can be achieved by using a shared cloud. If the above application models are widely used, it will have a significant impact on traditional security engineering companies and integrators.
