Your privacy has been exposed! How to protect information security in era of big data?

Modern society is a society of rapid development, advanced technologies, information flows, communication between people is becoming closer and closer, and life is becoming more convenient. Big data is a product of this era of high technology. McKinsey notes: "Today, data has permeated all industries and businesses and has become an important factor in production."

At present, use of big data is increasingly demonstrating its benefits and covering more and more areas. Our life. But while we are enjoying more personalized and customized services provided by big data, information covered by big data is also a treasure trove of resources, and serious problems caused by information leakage cannot be ignored.

According to 2018 Data Breach Loss Study, major data breaches are costly, with 1 million records worth $40 million and 50 million records worth $350 million. Companies affected by data breach lost an average of $3.86 million, up 6.4% year-over-year.

It was recently reported that darknet monitoring company 4iQ discovered a data file up to 41GB in size that contained 1.4 billion login credentials such as email addresses and passwords stored in plain text. Researchers believe that this is largest collection of databases ever found on dark web. Even a novice hacker can attack by buying database account password information.

Our country also drew attention to serious consequences of big data leakage and stepped up its efforts to combat this illegal act to ensure security of big data. Last November, State Administration for Market Regulation and National Standardization Management Committee issued 23 national standards, including "Smart City Information Technology Operation Manual", which will be effective from May 1 this year. The new national standard is aimed at establishing a unified information security standard in terms of improving security of digital identification technology for citizens and network identification and improving effectiveness of network security protection.

From a technical point of view, big data analysis and sharing is its advantage, but do not ignore privacy benchmarks, identity identification, data monitoring and scanning, data encryption, secure storage, channel encryption, transmission mode audit, data desensitization, data blocking and other aspects of work, to understand where red line of personal data, statistical network behavior model, real-time monitoring, whether there is a hacker intrusion to steal data. At same time, at management level, data security specialists or even groups should be created that will be responsible for data security. Only by establishing a good anti-attack and defense mechanism can we truly test security of system and understand methods and techniques of hacker attacks in order to better protect ourselves.

In addition, individual users should also be more vigilant, raise awareness about protection of personal information, regulate their online behavior, and refrain from disclosing personal information at will, such as names, identification numbers, fingerprints, bank cards, etc. . e. .

One more thing to note, though: despite detrimental effects of big data leaks, we can't deny value of big data and don't stop eating because we're choking. Big data technology itself is right, but those with evil intentions are wrong.
