What is the FIRST action to take when a data breach is suspected within an organization?

When a data breach is suspected, assessing the system status is the most critical initial action. This step involves determining the extent of the breach, identifying which systems and data may be affected, and understanding how the breach occurred. By thoroughly assessing the situation, an organization can gather vital information that will guide the subsequent actions taken to respond effectively.

This assessment is essential for making informed decisions about whether to notify law enforcement, change user access credentials, or shut down affected systems. Rushing into actions without understanding the situation may lead to further data loss or complicate the investigation. Therefore, ensuring comprehensive awareness of the scope and severity of the breach is pivotal in an effective incident response plan.
