Large data and network security problems in video surveillance field

In recent days, news of Chinese hackers attacking American companies and the media has been widely publicized, and the Chinese government and military have denied it, saying China is the main victim of cyber attacks. The fermentation of the matter, so that people's eyes quickly focused on the network information security above.

With the rapid development of computer technology, information network has become an important guarantee of social development. There are a lot of sensitive information, even state secrets, placed on the network, its security has attracted much attention. 2011, the domestic well-known programmers web site csdn by hackers, 600多万个 registered mailbox was forced to run naked; in 2012, Amazon's U.S. E-commerce site Zappos was hacked by hackers, 24 million of users of e-mail and passwords and other information stolen. These events all remind people to pay attention to network security issues.

In the era of analog monitoring, CCTV monitoring system security is high, there is almost no information security problems. Entering into the era of network monitoring, the open environment makes the information security issue an important concern. In particular, the rapid development of high-definition monitoring, Safe city, intelligent city, such as large-scale projects gradually spread out, more and more data, how to deal with large data network security issues, become a video surveillance industry new topics, but also bring new opportunities.

There are three major concerns in the field of video surveillance, such as large data and network security.

The first concern is that the value of video surveillance will increasingly be reflected in software and data mining, as well as more and more attention to cyber attacks.

After a period of development, especially in the construction of safe cities, video surveillance of the point has been gradually built in place, and continue to networking, application, industry penetration forward. The function of monitoring also gradually from the ex-post to prevent the advance, these only software and data analysis can do. On the other hand, when people use large data technologies such as data mining and data analysis to get more useful value, hackers are also using these big data technologies to launch attacks because big data is a big target that is more likely to be "discovered".

The second concern is that information security issues under large data will lead to changes in storage technologies and storage patterns.

Video surveillance storage technology and media from the VCR analog storage, DVR digital storage, gradually to NVR, NAS, Ipsan and other networked storage development, the future development direction is cloud storage. In the storage mode, there are mainly two kinds of centralized storage and distributed storage. Big data means huge amounts of data, and more complex and sensitive data that attracts more potential attackers. On the other hand, a large number of data collection, so that hackers can successfully attack one time to obtain more data, virtually reduce the hacker's offensive costs, increased the "yield." and distributed storage and cloud storage will be more flexible, but also reduce the storage pressure and risk, will be better developed.

The third concern is that information security issues under large data will spawn new opportunities and enhance the value of security.

At present, the security industry, enterprises are mainly selling hardware products, software has been to "give" the way to the customer. In the era of large data, manufacturers compete mainly with the strength of technology, integrated strength, innovative ability, service level, software will reflect its value. In order to deal with the risk of network information, video surveillance industry will derive new opportunities, while security will be cross-border to and IT industry integration stage, interpretation of its new value.

Therefore, large data in the new focus of competition at the same time, not only brought more security risks, but also brought new opportunities.
