Data exfiltration, in the context of a cyberattack, is the malicious transfer of sensitive information from a compromised system to remote cybercriminal servers.
What is Data Exfiltration
- Data theft is of greater security severity than a data breach because accessed data is already in transit.
- To prevent data exfiltration, malicious access must be intercepted before privilege escalation at the latest.
- Next-generation firewalls, an SIEM, and a Zero Trust Architecture could prevent data exfiltration.
