What should be initiated immediately after a reported security breach?

The initiation of incident response procedures is crucial immediately after a reported security breach because these procedures are specifically designed to address and manage the incident efficiently. They typically involve established protocols for identifying, containing, eradicating, and recovering from a security breach, ensuring that potential damage is minimized and that any ongoing threats are managed effectively.

Incident response procedures are critical for several reasons: they help to quickly assess the scope and impact of the breach, allow for prioritization of response actions, and facilitate communication among stakeholders. These procedures form the backbone of an organization's ability to manage security incidents and ultimately protect sensitive information and assets.

While other options such as reviewing security protocols or seeking government oversight are important steps to take at some point in the aftermath of a breach, they are not immediate actions. A media announcement, while perhaps necessary later for transparency, does not address the immediate need to contain and resolve the incident. The focus right after a breach must be on actively managing the situation through established incident response protocols to ensure a prompt and effective resolution.
