What is 'data exfiltration'?

Unauthorized transfer of data from a system

Data exfiltration refers specifically to the unauthorized transfer of data from a system. This can involve moving sensitive or confidential information outside of an organization’s network, often with malicious intent, such as stealing data for financial gain or industrial espionage.

Understanding this concept is crucial in cybersecurity as it highlights potential vulnerabilities in data security protocols and emphasizes the need for strong measures to prevent unauthorized access and data breaches. The other options relate to data management and security practices but do not align with the definition of data exfiltration. Securing data and encrypting information are preventive measures against data theft, while conducting internal audits pertains to reviewing and assessing organizational processes rather than the unauthorized transfer of data itself.
