What does the term "data exfiltration" refer to in the context of network security?

• A. The process of securing data within the network
• B. The unauthorized transfer of data outside the network
• C. Routine backups of data to an external source
• D. Data analysis for security vulnerabilities

Answer: (B)

The term "data exfiltration" specifically refers to the unauthorized transfer of data outside the network. This is a significant concern in network security because it often involves sensitive or confidential information being accessed and removed by malicious actors without the organization's knowledge or consent. Data exfiltration can occur through various means, such as hacking, malware, or exploiting vulnerabilities in the network. Understanding this term is crucial for network security professionals, as it highlights the risks associated with inadequate security measures. Organizations implement various strategies, such as data loss prevention (DLP) technologies, monitoring systems for unusual data movements, and strict access controls, to mitigate the risk of data exfiltration and protect sensitive information from being compromised.
