What is big data in cyber security?
In this blog, we will be discussing the risks of big data in cyber security.
The digital world is generating more than ever, with approximately 90% of the world’s data created in the last two years alone. Cybersecurity experts harness this wealth of data to protect individuals, organizations, and governments from cyber attacks. This abundance of data is what we refer to as “big data,” which is known as a large volume of data that is too complex for traditional data processing software.
In cybersecurity, big data analytics help identify patterns and anomalies in data to prevent attacks or quickly detect them when they occur. These analytics help identify different types of cyber threats, such as DDoS attacks, malware infections, and data breaches.
As per recent statistics, the global cost of cybercrime will increase by $6 trillion annually by 2021. Moreover, data breaches exposed 36 billion records in the first half of 2020 alone, with 52% of data breaches involving hacking.
Cybersecurity experts use big data in several ways to safeguard digital information. Firstly, they analyze vast amounts of data from network traffic, systems logs, and various security systems to identify anomalies, malware, and suspicious activities that may signify a threat. This analysis helps organizations understand potential risks and prevent them from occurring.
Secondly, cybersecurity professionals use big data to gain insight into trends, which may indicate possible future attacks. These insights help security professionals avoid emerging threats and deploy strategies that protect organizations before an attack occurs.
Thirdly, big data in cybersecurity is helpful for security teams when monitoring security controls, endpoints, and systems used to track the movement of cyber attackers. By detecting, containing, and removing the threat early, security experts can prevent the threat from becoming more significant.
In simple terms, big data plays an essential role in modern cybersecurity. The insights gained from extensive data analysis assist cybersecurity professionals in proactively identifying, mitigating, and managing risks in big data. Organizations that employ big data in cybersecurity can protect themselves and their customers from the significant financial and reputational risks of cyber attacks. As the volume of digital data continues to grow, so will the importance of big data for cybersecurity.
The risks of big data in cyber security
Big data has become an increasingly significant element of cybersecurity. However, with its use comes potential risks and challenges that businesses must be aware of to safeguard their systems, assets, and information from cyber-attacks.
Risks of Big Data in Cybersecurity are:
1. Lack of Data Privacy
Big data can help companies track and store significant amounts of data, including sensitive personal information. But as data volumes increase, so do concerns about data privacy. Malicious actors can leverage this data to launch phishing and other cyber attacks. Also, cyber-criminals can steal large volumes of data for identity theft and other fraudulent activities.
2. Data Breaches
The volume of data businesses collect creates an attractive target for cybercriminals looking to steal and sell valuable information on the black market. Additionally, as more companies integrate cloud storage solutions and APIs, it becomes easier for cybercriminals to penetrate these systems. Therefore, data breaches have become more prevalent, causing massive financial losses and tarnishing reputations.
3. Malware
Big data creates ample opportunities for the spread of malware. When combined with phishing attacks, malware can penetrate systems and networks, thereby risking valuable data. Hackers may create customized malware tailored to the specific characteristics of an organization’s IT environment.
Strategies to Mitigate Big Data Risk in Cybersecurity
1. Increased Monitoring
Businesses must take a security initiative to mitigate the . They must increase their monitoring activities to ensure they know all cyber threats targeting their system. For instance, by using intrusion detection systems, a business can detect cyber-attacks early before the attacker gains access to their network.
2. User Authentication
Passwords are no longer secure as they are easily compromised. However, multifactor authentication solutions (MFA) offer added security to passwords. An MFA solution involves authenticating the user’s identity through multiple authentication methods. MFA can include voice biometrics, facial recognition, fingerprints, and SMS verification.
3. Access Control and Authorization
Big data’s dynamic and complex environment increases the need for access control mechanisms. Risks associated with access to sensitive information require minimization; businesses must implement comprehensive access control and authorization procedures. These processes help to restrict access to critical systems, data, and applications.
4. Data Encryption
Data encryption plays a critical role in securing sensitive data. Data encryption techniques transform the readable text into cipher text that only authorized users with the decryption key can understand. Hence, if a hacker penetrates an organization’s security measures and accesses the data, it’s unreadable, rendering the attack useless.
5. Disaster Recovery and Business Continuity Planning
Disaster Recovery management is the process of restoring a business’s data and systems after a disaster has occurred. It involves the backup, restoration, and recovery of all critical data and applications compromised in a cyber attack, hardware failure, natural disaster, or any other disaster scenario.
Business Continuity Planning, on the other hand, is the process of creating a comprehensive plan for maintaining essential business functions during a disaster or crisis. The plan outlines the strategies, processes, and procedures to ensure business performance can continue during a disruption.
Conclusion
In conclusion, it is undeniable that there are many risks of big data in cyber security. As companies and organizations continue to amass and utilize large amounts of data, cybercriminals increasingly seek ways to exploit this information for their malicious intentions. The sheer volume of data creates new challenges for promptly identifying and responding to potential threats.
However, it is essential to note that big data can also be a powerful tool in enhancing cyber security. By utilizing advanced analytics and machine learning, organizations can proactively detect and respond to potential threats before they cause significant damage. Moreover, proper encryption and data protection measures can help ensure that sensitive information remains secure even in a breach.
