Exfiltration is "[t]he unauthorized transfer of information from an information system." [1]

Overview[]

"Cyber criminals can use malware or other methods to infect a network and steal data using a process known as exfiltration.... Therefore, to prevent malware and data exfiltration, cyber defense systems often use a concept known as defense-in-depth, the deployment of a variety of network security devices at different layers of the network, to protect sensitive network data."[2]
