What type of approach is the primary focus of reactive techniques?

The primary focus of reactive techniques lies in post-event analysis and detection. This approach is utilized after a security incident or breach has occurred. Reactive methods emphasize understanding what happened, how the security failure took place, and analyzing the effects of the event. By concentrating on incident response and forensics, organizations can identify vulnerabilities or gaps that were exploited, assist in recovery efforts, and implement improvements to prevent future occurrences.

In contrast, preventive security measures aim to stop incidents before they happen, proactive vulnerability scanning involves actively seeking out and fixing potential security weaknesses before they can be exploited, and encryption of data at rest is a security practice intended to protect data by making it unreadable to unauthorized users. These methods, while important in a holistic security strategy, do not align with the primary focus of reactive techniques.
