What are the three key pillars of security operations?

The three key pillars of security operations are prevention, response, and recovery. Prevention involves proactive measures taken to stop security incidents before they occur, such as implementing security policies, conducting background checks, and engaging in regular threat assessments. This foundational pillar is essential in minimizing risks and safeguarding assets.

Response refers to the actions taken during and immediately after a security incident has occurred. This includes alerting the necessary authorities, managing the situation, and ensuring the safety of individuals involved. An effective response is critical for mitigating the impact of incidents and protecting both people and property.

Recovery involves the efforts made after an incident to restore normal operations and evaluate how the situation was handled. This pillar focuses on learning from the incident, reinforcing security measures, and preparing for future challenges. Recovery ensures that an organization can bounce back from security breaches and become more resilient over time.

The other options, while mentioning important concepts in security operations, do not encapsulate the comprehensive approach that prevention, response, and recovery provide in addressing security challenges. They may focus on specific aspects or other processes but do not collectively represent the overarching framework crucial for effective security operations.
