A cybersecurity analyst receives an alert about a potential data breach involving the compromise of PII (Personally Identifiable Information). What is the BEST initial action to take?
Notify all affected parties
Initiate remediation measures to address the vulnerabilities
Isolate the affected systems to minimize data leakage
Begin data analysis to identify the source of the breach
In the event of a potential data breach involving sensitive information like PII, the first priority is to contain the breach to prevent further data loss. Containment actions may include isolating affected systems or networks to stop the spread of the breach. Data analysis, remediation, and notifying affected parties are secondary steps that come after the threat has been contained and further analyzed.
