Understanding Big Data Security
Big data refers to large volumes of unstructured, semi-structured, and structured data that cannot be easily analyzed or processed using conventional methods. It is generally characterized by the “3Vs”.
- Volume (the vast amount of data)
- Velocity (the high speed at which data is generated and processed), and
- Variety (the diverse types and formats of data).
Big data covers information from numerous sources, such as financial transactions, social media, sensor networks, etc. The primary aim of analyzing or processing big data is to gain valuable insights, trends, and patterns that can stimulate decision-making and drive innovation.
Key Security Challenges and Risks Big Data Poses Today
Due to its unique characteristics, big data security poses several key challenges and risks. For instance, a survey conducted in 2021 by NewVantage Partners revealed that 99 percent of senior C-level executives of several Fortune 1000 organizations were pursuing big data programs.
Even more significant was that 96 percent of these C-level executives reported their organizations had had considerable success with artificial intelligence and big data programs. But let’s highlight the challenges associated with big data.
First off, the massive volume of data generated daily makes it incredibly challenging to ensure 100 percent integrity, confidentiality, and availability. Storing and analyzing large datasets require innovative encryption mechanisms and robust infrastructure to sufficiently protect against data breaches and unauthorized access.
Secondly, the velocity or speed at which data is generated daily calls for real-time security measures for detecting and responding to any potential threats promptly. Cyberattacks can readily exploit every vulnerability within data processing systems, resulting in manipulation, data loss, or even disruption of crucial services.
Finally, the massive variety of available data sources also complicates ensuring highly consistent security controls across various types of data.
Additional risks linked with big data include privacy concerns, as big data frequently contains personally identifiable information (PII). Improper handling or inadequate anonymization of Personally Identifiable Information may result in regulatory non-compliance and privacy breaches.
Another significant challenge involves the complexity of machine learning algorithms and data analytics utilized on big data. Malevolent attacks can influence or manipulate the outcomes of these algorithms.
This could lead to misleading or biased results. Moreover, the considerable lack of skilled experts adept in big data security heightens these massive risks. This emphasizes the need for special skillfulness to address these unique security challenges that big data poses.
Best Practices for Securing Big Data
So, what are the best practices to secure big data? It’s vital to protect the privacy of individuals and safeguard information. Therefore, here are some of the best practices for securing big data:
1. Data Encryption
Encryption plays a key role in protecting the integrity and confidentiality of big data. It ensures that even if unauthorized individuals somehow gain access to crucial data, they cannot manipulate or interpret the data without the encryption keys. Encryption helps mitigate the profound risks associated with unauthorized data access and data breaches.
2. Access Control and Authentication
To fortify access control, organizations should readily implement robust authentication mechanisms. This may include biometric authentication, multi-factor or two-factor authentication, and secure password policies. Strong authentication mechanisms help minimize the risks of unauthorized access.
3. Anonymization and Data Masking
Anonymization involves ensuring that sensitive data such as personally identifiable information (PII) can’t be directly linked to a particular individual. Techniques like suppression, generalization, and perturbation are employed to modify or remove identifiers, protecting privacy while retaining data utility.
Data masking involves replacing sensitive information with highly fictitious but realistic data. It enables organizations to utilize and share data for several non-production purposes while protecting the utmost confidentiality of the original data. Techniques such as shuffling, substitution, and hashing are used for data masking.
Expert Insights and Strategies for Big Data Security
Do you still ask: What are best practices to secure big data? Which strategies should you apply? Here are some expert insights and strategies that organizations can deploy when it comes to big data security:
1. Determine Your Data Strategy
Determining your data strategy is the #1 step in managing big data: It involves determining the exact data to collect, how to collect it, and what to do with it. Your business objectives will play a key role here as they must align with your data strategy for maximum results.
2. Ensure Data Quality
Managing big data is not only all about analyzing copious amounts of data. It also involves ensuring the quality of data. Poor data quality leads to poor decision-making as a result of incorrect insights. The consequences of this can be grave for your business.
Therefore, clean and validate your data to ensure its completeness, accuracy, and consistency. Establish data governance, which defines who accesses the data, how it should be secured, and how it can be utilized.
3. Invest in the Right Tools
Choosing the right tools for managing big data is crucial since several are available. Your choice of tools must align with your business objectives and data strategy. There are choice tools for performing real-time analysis and processing large volumes of unstructured data, respectively.
So, using the right tools will help you analyze your big data to extract valuable insights. These insights will, in turn, inform your business decisions, which is the primary goal.
4. Utilize Predictive Analysis
Predictive analysis involves using machine learning techniques and statistical algorithms to process data and make acute predictions about future outcomes. This powerful tool can help you forecast trends, identify patterns in your data, and make excellent informed decisions.
5. Work with Data Experts
To manage big data, you need specialized expertise. You should have a team of data specialists who can design and deploy your data strategy. They should be capable of performing data analysis and managing your data infrastructure.
