According to the Shared Assessments Certified Third Party Risk Professional (CTPRP) Study Guide, data loss prevention (DLP) is a strategy for preventing the unauthorized disclosure, transfer, or misuse of sensitive data, such as personally identifiable information (PII), personal health information (PHI), or intellectual property (IP)1. Endpoint security is a component of DLP that focuses on protecting the devices (such as laptops, tablets, or smartphones) that access and store sensitive data from internal or external threats2. Therefore, data loss prevention in endpoint security is the strategy for preventing exfiltration of confidential information by users who access company systems, as this could result in data breaches, regulatory fines, reputational damage, or competitive disadvantage3.
The other options are not the best descriptions of data loss prevention in endpoint security, as they either relate to different aspects of data protection or security, or do not address the specific goal of preventing data exfiltration. Data backups are a strategy for ensuring data recovery in the event of a disaster, but they do not prevent data loss or leakage from unauthorized access or transfer. High-availability is a strategy for ensuring data availability and continuity, but it does not prevent data loss or leakage from malicious or accidental actions. Malware prevention is a strategy for ensuring data integrity and confidentiality, but it does not prevent data loss or leakage from legitimate users who may misuse or overshare data.
