Which of the following incidents would fall under the responsibility of incident response teams?

The responsibility of incident response teams primarily revolves around identifying, managing, and mitigating security incidents that could jeopardize an organization's information systems and data integrity. Data breaches are a significant concern for organizations, as they involve unauthorized access to sensitive information, potentially leading to data loss, financial damage, or reputational harm.

When a data breach occurs, incident response teams are tasked with quickly assessing the situation, containing the breach, conducting forensic analysis to understand its scope, and implementing measures to prevent future occurrences. This involves coordinated efforts across various domains, including IT security, legal, and public relations, to effectively address the breach and communicate with affected parties.

In contrast, regular database maintenance, employee onboarding procedures, and software updates are aspects of IT operations and management rather than incidents demanding immediate incident response. These activities are essential for the continued robustness and security of systems but do not typically involve the reactive measures that incident response teams implement in response to a security threat like a data breach.
