What does the term "data exfiltration" mean?

The term "data exfiltration" refers to the unauthorized transfer of sensitive data from a system to an external location. This process typically occurs without the consent or knowledge of the organization that owns the data. Data exfiltration can happen through various means, including hacking, insider threats, or exploiting vulnerabilities in software or hardware.

Understanding this concept is crucial for cybersecurity professionals, as preventing data exfiltration is a major part of safeguarding an organization’s information assets. Organizations implement various security measures, such as intrusion detection systems, data loss prevention tools, and employee training, to mitigate the risks associated with data exfiltration.

The other options describe different data-related processes that do not align with the concept of unauthorized data transfer: integrating new data relates to data entry processes, backing up data involves creating secure copies, and retrieving lost data pertains to data recovery efforts. None of these options accurately reflects the intention or implications tied to data exfiltration.
