  1. Patching vulnerabilities

  2. Resetting passwords

  3. Implementing additional security controls

  4. Recovering lost data
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Recovering lost data is not a method for eradicating a data breach. It is a step that is typically taken during the recovery phase of the data breach response process.

Multiple choice

Which of the following is NOT a key element of a post-mortem analysis of a data breach?

  1. Identifying the root cause of the breach

  2. Evaluating the effectiveness of the response

  3. Updating security policies and procedures

  4. Conducting a risk assessment
