If adverse events or conditions cause a system to fail to operate appropriately, they can cause all manner of harm to valuable assets. As I outlined in previous posts in this series, system resilience is important because no one wants a brittle system that cannot overcome the inevitable adversities. In the first post in this series, I addressed these questions by providing the following, more detailed, and nuanced definition of system resilience: A system is...

This post was co-written by Timur Snoke. In this post, we aim to help network security analysts understand the components of a cybersecurity architecture, starting with how we can use endpoint information to enhance our cyber situational awareness. Endpoints collect a wealth of information valuable for situational awareness, but too often this information goes underutilized....

A system resilience technique is any architectural, design, or implementation technique that increases a system's resilience. These techniques (e.g., mitigations, such as redundancy, safeguards, and cybersecurity countermeasures) either passively resist adversities, actively detect adversities, react to them, or recover from the harm they cause. System resilience techniques are the means by which a system implements its resilience requirements. Resilience techniques can also be viewed as architecture, design, or implementation patterns or idioms. This post begins...
