b. Increased customer trust
In today’s digital world, data security is critical to building customer trust. With rampant incidents of data breaches, customers are increasingly concerned about how businesses handle their personal and sensitive data. According to Statista, only 46 percent of U.S. customers trusted their banks and financial institutions to protect their data. This data shows there is a trust deficit among customers and businesses when it comes to data privacy and security.
Big data security helps in protecting customer data from unauthorized access. When customers see that a company protects their data and privacy, they are more likely to trust the company and remain loyal to it. Many organizations employ reputed third parties for security audits, validating the company’s data security commitment and reassuring customers that their data is safe.
c. Improved decision-making
Big data security helps maintain data integrity and accuracy by protecting it from unauthorized access. Security measures like encryption, restricted access, and authentication ensure that only authorized individuals can access sensitive information. A secure data environment helps find the correct insights and patterns, assisting stakeholders in making the right and data-driven decisions. For example, banks can use big data to improve their risk management and fraud detection capabilities and offer loans to customers with good credit history. However, this is possible only when the data is secure and correct.
d. Competitive advantage
Big data security offers businesses a competitive advantage by safeguarding critical assets and helping them make data-driven decisions. By protecting customers’ data and ensuring privacy, companies can enhance trust and loyalty, ultimately boosting customer retention. Businesses with robust security measures also attract partners who can help in business growth. These factors contribute to the company’s growth and help outpacing competitors yet to invest in big data security analytics.
Common big data security challenges
Securing big data is a significant challenge in today’s digital landscape as attackers use sophisticated technologies and innovative methods, making it essential for businesses to understand big data security challenges.
Let’s look at the top big data security challenges that will help you take appropriate measures to secure your data.

As the volume grows, processing the data while ensuring security measures requires careful planning and implementation of robust security practices.
f. Employee theft
Every employee in an organization has some amount of access to the data, especially those who are involved in big data analysis. Some employees even have insider knowledge of the organization’s data systems, including access controls, security protocols, and passwords so password managers on mac and windows are big game changers. An employee with access to a big data system can exploit the authority to gain unauthorized access to sensitive data. They can also manipulate data to cause financial and reputational harm to the organization.
Top 10 big data security best practices
Implementing robust big data security measures is crucial for safeguarding sensitive information and maintaining data integrity. Here are ten security best practices businesses can implement to secure big data.
1. Encryption
Encryption plays a critical role in big data security as it converts data into an unreadable format, called ciphertext, that can only be deciphered by the users with the correct key. Encryption ensures that sensitive data remains confidential during transit and while in rest, thus protecting data stored on computers, servers, and within a network. If any unauthorized party gains access to the data, they can’t decode it. Moreover, encryption helps maintain data integrity, making it difficult to tamper with data.
2. Effective user access control
Big data contains sensitive and valuable information, and protecting it is critical for businesses. Effective user access control ensures that only authorized users can access, modify, or delete this data, reducing the risk of unauthorized access, data breaches, or theft. There are multiple ways to implement user access control for big data. One common approach is using role-based access control, as it allows authorities to create roles and assign access according to those roles.
