Which of the following actions helps improve incident response effectiveness?

Regular training for incident teams is essential for improving incident response effectiveness. Such training helps team members stay current with the latest cybersecurity threats, response techniques, and tools. By regularly engaging in simulations and scenario-based training, incident response teams can develop a cohesive response strategy, enhance their skills under pressure, and ensure they can collaborate effectively during real incidents. This preparedness allows for quicker and more efficient responses, minimizing the potential impact of incidents on the organization.

The other actions listed do not contribute to improving incident response effectiveness. Disabling user accounts after hours may enhance security, but it does not directly improve the capabilities or readiness of the incident response team. Using generic passwords is detrimental to security practices and can lead to increased risks rather than effective response. Ignoring minor security incidents can result in larger issues later, as small incidents can escalate if not addressed promptly, thus undermining the preparedness and responsiveness of an organization.
