Big Data Security

We have entered the era of big data, and much of our information has been disseminated through various channels, which inevitably leads to security problems.

So, what do we rely on to keep our data safe? Can we only watch personal data and privacy leaking everywhere?

Recently, big data security incidents are on the rise. A few days ago, the Guangdong police cracked a high-tech economic crime case. Ye Shiguang, a 17-year-old "hacker", hacked several commercial bank websites, stolen data such as depositor ID numbers, bank card numbers, payment passwords, etc. The unauthorized swipe of someone else's credit card involved nearly 1.5 billion yuan and involved 49 banks.

In February 2018, the world's largest cyber theft ever occurred. The hacker hacked the Bangladesh Central Bank's account at the Federal Reserve Bank of New York and stole $ 81 million. Later, Bangladesh officials said that the hacker had a spelling error, otherwise it would subsequently make a transfer of nearly $ 1 billion.

In March 2018, a radical hacker group associated with Syria launched a cyber attack on a water plant. The hacker manipulated the system to change the amount of chemicals entering the tap water, hindering the water purification process.

With more devices connected to the Internet, the higher the probability of the occurrence of cyber attacks, cyber attacks first aim at big data, which causes loss of big data, intelligence leaks, and disrupts the safe operation of the network. Big data technology is a double-edged sword, which can benefit the society and the people, and can be used by some people to damage the public interest and the interests of the people.


Big data security system construction is imperative

In the era of the Internet and even the Internet of Things, if we cannot solve security problems well, it will affect the development of all aspects of society. Therefore, while encouraging the development of big data, governments at all levels should simultaneously consider building a big data security system.

It is worth noting that the traditional network security thinking can no longer guarantee the security in the era of big data. The traditional network security protection idea is to divide the boundary, separate the internal network from the external network, separate the service network from the public network, and use terminal equipment to isolate potential risks. By setting up gateway equipment and network traffic equipment at each border, to guard the "border" in order to solve security problems. But with the advent of mobile Internet and cloud services, mobile terminals shuttle between 4G signals, Wi-Fi signals, and cables, and the network boundary has actually disappeared.

Many traditional large enterprises believe that as long as they purchase the server and build an independent computer room, arranging specialized technicians can protect the company's data from being leaked and protect the company's information security. But in fact, in today's Internet era, this traditional method is more likely to be broken by criminals. In terms of technical strength, most enterprises are not specialized in network security and data security, and the technical barriers they set up are difficult to stop professional hackers.

Cloud platform and big data need "two swords combined"

Some network security personnel said that with the continuous development of cloud computing, storing data on a cloud platform may be more secure than traditional enterprise information protection. Compared with individuals, cloud platforms have professional computing platforms, and strong technical teams can better cope with attacks from hackers.

Different users, whether it is CPU, memory, storage or network, are isolated from each other by default, neither seeing each other's data nor affecting each other. Just like a five-star hotel is divided into multiple rooms, they are independent and closed to ensure that different tenants do not interfere with each other and data isolation.



to sum up

As the network security team grows, using the dual protection of cloud platforms and big data, hackers are no longer just against you as before, but against an entire professional security team. Of course, some information leaks are due to the sale of internal personnel, so not only to strengthen the strength of network security, but also to check the information department.
