When it comes to huge technological discoveries and inventions, the emergence of Big Data has totally transformed the world of technology enabling people to make data-driven decisions and optimize the performance of any industry where it’s widely used. Its impact has been revolutionary when it comes to preventative measures for patients in the health care system. Moreover, it helps to solve the problems within the field where it appeared, i.e. the IT sector.  One of such issues tackled by Big Data is cybersecurity. Every device connected to the internet can be used as a target for malicious attacks aimed at stealing personal data, compromising the system, installing ransomware, deleting the important data, and others. Having access to huge data chunks, Big Data, applied to the security, can significantly increase the system protections and be ready for the attacks utilizing all the power of data analysis. It’s common to view Big Data Security as a set of measures and tools that are used to protect the information and analytic flows from hacking attempts. Let’s see how the insights obtained from it combined with Machine Learning can also enhance the security of the environment where it’s applied.

How Big Data is Used in Web Security?

The first and foremost of applications of Big Data Security is how it can be applied to practice. Here are its most common use cases:

Discovering System Vulnerabilities     

Using real-time checks, security analytics solutions assess the overall system’s health and indicate the potential threats and weaknesses that are to be ousted to restore the normal performance and even differentiate them by indicating a threat level.

Minimizing Internal Attacks

While people tend to protect from external intrusions, they often neglect the risk of internal threats. Various solutions for User and Entity Behavior Analytics like Aruba or VMware running on Big Data exist to avoid them. They analyze user actions on a daily basis to outline unusual behavior and match it with known malicious patterns that can lead to insider breaches.

Predicting and Forecasting Security Threats

Having the opportunity to analyze the previous incidents related to the security of an organization,  smart AI algorithms running on Big Data can be used in site reliability monitoring tools to send notifications so that the system downtimes can be avoided.

Visualizing and Preventing Critical Incidents

Based on the analysis of the incidents in the company using server logs as well as their visual representation, it’s possible to see the previous causes of the issue, the alarming pre-conditions before a system failure happens, and previous consequences and solutions that were applied to mitigate the issue. This information becomes useful when it comes to system automation, combining Big Data with smart algorithms that can be taught to perform actions without human intervention. 

Contribute to Malware Scanners/Firewall Protection

Since the new security threats appear every day the Big Data technologies used by Malware protection software and firewalls analyze a huge number of files, behavior flows and script patterns to outline malicious attacks and help to block them to keep the system safe.

Prevent Fraudulent Activities

For businesses accepting online payments, it is hard to underestimate Big Data’s contribution since its combination with Machine learning powers the tools that analyze the identity documents and credit card details to detect criminals and eliminate frauds with stolen bank account details. 

Hence, Big Data is applicable in all industries especially those dealing with sensitive data, such as Finance and Healthcare sectors, as well the IT and Governmental structures. Apart from big corporations, small eCommerce businesses benefit from Big Data Security as well as individual users (Everyone uses an antivirus on a PC, right?). The increasing popularity of Big Data Security enhancements and its promising implications make more and more young people consider starting a career in this sphere or switch from other adjacent fields to it. 

Skills and Requirements for Building a Successful Career in Big Data Security

In order to start a successful career in Big Data Security, young specialists would need to learn a bunch of skills related to Machine Learning, Coding as well as undergo Cybersecurity Training in addition to that. Taking into account the field complexity, it’s not possible to become a Big Data Security specialist overnight but it’s definitely worth investing your time in increasing the competences in Big Data. 

Depending on the company and the position you are applying to, the requirements can differ but the majority of the job postings for entry positions for Big Data Analyst or Scientist include the prerequisite knowledge of the following:

  • Python/Java/C
  • Machine learning
  • Database Management (NoSQL)
  • Hadoop
  • Linux (Bash Scripting) 
  • Cloud Technologies
  • Apache Spark
