What is the most effective option for preventing and detecting future data breaches in a corporation?

Implementing a dedicated Computer Incident Response Team (CIRT) is the most effective option for preventing and detecting future data breaches within a corporation because such a team is specifically designed to prepare for, respond to, and recover from cybersecurity incidents. The CIRT's primary role is to handle security breaches or attacks, ensuring that the organization can quickly mitigate any damage and restore normal operations.

A dedicated CIRT not only focuses on incident response but also engages in proactive measures, such as developing and updating the incident response plan, conducting simulations and drills, and analyzing previous incidents to strengthen defenses against future breaches. This type of structured response capability ensures that all employees understand their roles in a security incident, thus fostering a culture of security awareness throughout the organization.

While increasing the IT budget, conducting regular cybersecurity training, and hiring an external cybersecurity firm for penetration testing are all beneficial practices, they do not provide the comprehensive, ongoing framework that a CIRT offers for rapid response and future prevention. A CIRT's continuous monitoring and immediate intervention capabilities make it crucial for effectively managing and minimizing the risks associated with data breaches.
