Minimizing Disruption in Responding to a Data Breach
Question
Following a recent data breach, a company has hired a new Chief Information Security Officer (CISO)
The CISO is very concerned about the response time to the previous breach and wishes to know how the security team expects to react to a future attack.
Which of the following is the BEST method to achieve this goal while minimizing disruption?

A. B. C. D. E.C.
The BEST method to achieve the CISO's goal of understanding the security team's response to a future attack while minimizing disruption is to conduct a tabletop exercise, which is option C.
A tabletop exercise is a simulation of a security incident or breach that allows the security team to evaluate and refine their response procedures. During the exercise, the team discusses the steps they would take to identify and contain the threat, communicate with stakeholders, and restore operations.
This method allows the security team to test their response plan without causing any actual disruption to business operations. It also provides an opportunity for the team to identify any gaps or weaknesses in their response procedures and make necessary improvements.
Performing a black box assessment (option A) involves testing the security of a system from an external perspective without prior knowledge of its internal workings. While this type of assessment can identify vulnerabilities, it can also be disruptive and time-consuming.
Hiring an external red team audit (option B) involves engaging a team of ethical hackers to simulate an attack on the company's systems. This method can be useful for identifying vulnerabilities and testing the response of the security team, but it can also be expensive and disruptive.
Recreating the previous breach (option D) is not a recommended method as it can be disruptive and costly. Additionally, it is not a reliable method to assess the security team's response to a future attack since the circumstances of each breach can be different.
Conducting an external vulnerability assessment (option E) involves identifying vulnerabilities in a company's systems and applications from an external perspective. This method can be useful for identifying weaknesses that an attacker could exploit, but it does not test the security team's response to an attack.
In conclusion, a tabletop exercise is the best method to achieve the CISO's goal of understanding the security team's response to a future attack while minimizing disruption. It allows the team to test their response procedures and identify any weaknesses in a controlled environment.
