Privacy and data security in big data
Posted: Wed Dec 11, 2024 6:10 am
Suppose your most personal information, from your shopping preferences to your medical data, was accessible to anyone with the skills to hack a system. Would you feel safe? Welcome to the era of massive data analysis, or Big Data.
Both individuals and companies are affected and influenced by the security and privacy of Big Data, which cannot be overlooked. On the one hand, the ability to collect, store and analyze massive amounts of information gives companies special power to improve their services and products. But on the other hand, this massive collection of data poses serious challenges regarding privacy.
For those looking to enter the world of Big Data with a solid understanding of these challenges, the Master in Big Data & Analytics from EAE Business School Madrid offers training focused on developing skills to implement effective privacy and security strategies.
The importance of privacy and data security in Big Data
Data privacy and security in big data are critical players in managing massive amounts of information. This is due to the sensitive nature of the data collected, which can include financial job seekers phone number data information, medical history, consumer habits and online behaviors. If this data falls into the wrong hands, the consequences can be devastating for both individuals and businesses. The risk of privacy breaches affects consumer trust, but can also result in legal penalties and reputational damage.
Privacy challenges in the context of big data
Massive data collection
Big Data is characterized by the collection and analysis of massive volumes of information, coming from various sources such as social networks, IoT devices, commercial transactions and more. If this massive data collection is not managed properly, it can lead to the accumulation of sensitive information without the explicit consent of users, violating fundamental privacy principles.
Risks of privacy breaches
Personal data, once collected, can be susceptible to unauthorized access, theft, and misuse. Big Data privacy breaches through cyberattacks, phishing, and other forms of intrusion are constant threats that jeopardize data security. And the lack of adequate Big Data security measures amplifies these risks, making the implementation of robust protection systems an imperative need.
Data anonymization issues
Data anonymization is a technique used to protect Big Data privacy by removing or modifying personal identifiers from data sets. But effective anonymization is difficult to achieve and maintain. Anonymized data can, in many cases, be re-identified through advanced analytics techniques, especially when combined with other data sources.
Main threats to data security in Big Data
Attackers use a variety of methods to exploit vulnerabilities in systems, from malware and ransomware to DDoS attacks. Vulnerabilities can be present in various layers of the technology infrastructure, from hardware to software. Attackers can also gain access to data systems through techniques such as malware, including viruses, trojans and ransomware, phishing, password hacking or the use of stolen credentials.
This type of breach compromises Big Data privacy, and can lead to significant financial losses and irreparable damage to the organization’s reputation.
Big Data Privacy Regulations and Rules
GDPR (General Data Protection Regulation)
The GDPR, or General Data Protection Regulation, is one of the most important regulations in the field of Big Data privacy. Implemented in May 2018, the GDPR establishes a rigorous legal framework for the protection of personal data of citizens of the European Union.
