In cybersecurity, it is increasingly crucial to move focus from mean time to detect (MTTD) to mean time to contain (MTTC) to enhance organizational resilience. This article provides a playbook consisting of eight steps that align IT and security, aiming to reduce MTTC effectively. Key measures include continuous discovery of assets, swift decision-making based on credible signals, and trustworthy containment strategies that are easily reversible.
The first step involves understanding the assets within the network thoroughly. Continuous monitoring is essential to identify any surprises that may require containment. Next, it discusses the importance of quick decision-making while ensuring safety, utilizing a structured approach for rapid containment actions. Following that, the article emphasizes implementing a joint operating model for IT and security, focusing on shared metrics that matter to the business and avoiding common pitfalls such as automating without understanding the context. Finally, a 30/60/90-day rollout plan is proposed to gradually implement and scale effective cybersecurity measures.
