What happens to a file when it is quarantined in a data loss prevention system?

When a file is quarantined in a data loss prevention (DLP) system, the appropriate mechanism involves denying the user access to the original file. This action can be crucial in preventing the potential leakage or unauthorized distribution of sensitive information. Quarantining a file serves as a protective measure that keeps potentially harmful or non-compliant data secure.

Typically, the file may be either encrypted or moved to a secure location where it cannot be accessed without proper authorization or further evaluation. This process ensures that any data that may pose a risk or violate policies is contained and evaluated before any further actions are taken, thus maintaining the organization’s data integrity and compliance requirements. Quarantine allows security teams to assess the situation and determine the next steps for the file, whether that involves restoring access, deleting the file, or taking additional action based on the DLP policies in place.

This functionality aligns with the overall goal of DLP systems, which is to monitor, detect, and protect sensitive information from unauthorized dissemination or access, while ensuring that any incidents that arise from potential data breaches are handled appropriately.
