Those who deal with Big Data should learn all it is to learn about GDPR (General Data Protection Regulation) – legislation passed by the EU in 2016. It changed a lot. Till 2018 entrepreneurs had to prepare the methods to grant their customers better control over their personal data that was collected by the companies. With the new law, clients need to be informed and asked for permission before collecting their data.

There are also many limitations on what can be done with the data and how long can it be stored. All the companies that do business in the EU or with EU citizens have to obey rules presented in GDPR. This legislation’s main goal was to ensure safety of collected personal data. Any issue with the security should be reported immediately to a Data Protection Officer. A company that will violate GDPR laws needs to pay a big fine (security breach happened recently to the British Airways – read more about it here). 

Nowadays, as most companies are using tools for data analytics to produce useful insights for business, understanding business intelligence and data security is a must. Securing your data is the most important step; no matter if you run a small, medium or big company.

What kind of big data security challenges might your company encounter?

Although it may be hard to believe, there are still many organizations which try to save money on security in the case of Big Data, on encryption. Any company that does not invest in security is vulnerable to attacks and leaks. When setting your priorities, always think of security first.

One of the most common mistakes is inadequate prevention of unauthorized access to sensitive data. Imagine your company’s financial or sensitive information is lost or stolen (information such as logins, passwords, information from personal accounts). This could mean not only financial losses but also reputation damage and legal responsibility. Of course, you have to grant access to some employees, so they can perform their daily duties, but you need to think carefully about who should be able to access your businesses’ important data and how you can protect it.

Data privacy violations are the next challenge for companies that need to handle big data. Information comes from various sources at high speeds, in huge amounts and in different types.

Industries such as e-commerce especially need to protect users’ privacy. Personal information is an essential part of big data. Security breaches can affect many groups of people or business partners. They can have both financial and legal repercussions. Before storing data, companies should anonymize it. Still, removing some unique identifiers from data is not always enough to make it fully anonymous and there are some techniques that can be used in order to de-anonymize information that is why additional security solutions should be used.

Encryption is the way to keep data safe, but data can’t be encrypted if your systems are about to perform some operations on it. Your company needs a powerful solution which enables processing encrypted data. If you use the right technology to work with data in the cloud, it will be able to operate without knowing what the data actually is. Securing your Big Data solution is even more important than securing other applications, because Big Data solutions usually work as a Data Warehouse and contain data from many other company systems. When someone gets uncontrolled access to your Big Data system, he might get data from all other company systems.

The second process that a user has to go through in order to access and work with data and services is authorization. Authorization controls what a user can do in a given environment. First the person has to be authorized to perform any work on data or applications. 

Data encryption 

Thanks to the earlier mentioned encryption you can keep unauthorized users away from your data; no matter if at rest or currently in use. Data encryption is a process of translating data into different forms or code, making it impossible to discover the protected information without a decryption key or a special password. Nowadays, it is the most popular and effective data security solution used in business. The two main types are symmetric and asymmetric encryption. Modern data protection solutions can provide encryption of devices, messages (like emails) and data. Symmetric encryption uses the same key in order to encrypt and decrypt the data. That is why this method is faster. Asymmetric encryption uses two keys one is necessary to encrypt data and the second to run the decryption process. One of the keys is called private, and it is only known to the owner, while the other is available to some group of people which is why it is called a public key.

Big data security tools and solutions should be chosen considering the specific needs of a particular company or industry. Invest in the highest quality security methods data is one of the most important assets your company has. There are many technologies, frameworks and even cloud providers of Big Data solutions. You need to remember that you won’t find any simple way for Big Data Security. Security standards need to be applied in each company accordingly.
