D-SF-A-24 Exam Dumps - EMC Security Questions and Answers

Double Extortion Ransomware:This type of ransomware not only encrypts files but also attempts to encrypt backups and shared, networked, and cloud drives1.

Attack Method:Attackers first exfiltrate sensitive data before encrypting it, then threaten to release the data if the ransom is not paid, hence the term 'double extortion’1.

Impact on Organizations:This method increases the pressure on the victim to pay the ransom, as they face the risk of their sensitive data being published or sold1.

Prevention and Response:Organizations should implement robust backup strategies, including offsite and offline backups, and have an incident response plan that includes dealing with ransomware and data breaches1.

Double extortion ransomware attacks are particularly dangerous because they combine the threat of data encryption with the threat of data exposure, significantly increasing the potential damage to the victim organization1.

User Analytics:UEBA systems analyze user behavior to establish a baseline of normal activities and detect anomalies12.

Threat Detection:By monitoring for deviations from the baseline, UEBA can detect potential security threats, such as compromised accounts or insider threats12.

Data Analysis:UEBA solutions ingest and analyze large volumes of data from various sources within the organization to identify suspicious activities12.

Behavioral Analytics:UEBA uses behavioral analytics to understand how users typically interact with the organization’s systems and data12.

Machine Learning and Automation:Advanced machine learning algorithms and automation are employed to refine the analysis and improve the accuracy of anomaly detection over time12.

UEBA is essential forA .R.T.I.E.as it provides a comprehensive approach to security monitoring, which is critical given the diverse and dynamic nature of their user base and the complexity of their IT environment12.
