Reducing Outage Impact: Resilience-by-Design for Critical Services
Summary
This article discusses how critical infrastructure, increasingly reliant on cloud-first services, is vulnerable to rapid disruptions. It advocates for a "resilience-by-design" approach, integrating DevSecOps, cloud-native architecture, and incident response to proactively build resilience rather than reactively patching problems. The session will cover strategies for standardizing secure pipelines, automating controls, and aligning service level objectives (SLOs) with business risk, referencing frameworks like CISA's Cybersecurity Performance Goals and NIS2.
IFF Assessment
The article provides guidance and strategies for defenders to improve the resilience and security of critical services, which is beneficial for overall cybersecurity posture.
Defender Context
Defenders need to understand the interconnectedness of modern critical infrastructure and the threats posed by adversaries exploiting this complexity. Adopting a 'resilience-by-design' methodology is crucial for minimizing the impact of disruptions, whether from technical failures or cyberattacks, by integrating security and recovery into the core architecture.
