smittofall

Smittofall is a term in systems theory and cybersecurity used to describe a rapid, multi-vector cascade of failures triggered by a single initiating incident within a distributed network. The concept emphasizes how dependencies and feedback loops can convert a localized fault into widespread disruption, often across different services, teams, and geographic regions.

Origin and usage: The word is a neologism; its etymology combines Latin smitto meaning "I send" with fall to convey cascading collapse. It appears in some security research discussions and incident reports to label a specific class of cascading incidents, though it is not a formal technical standard.

Mechanism: A smittofall begins with an initiating event such as a faulty update, compromised credential, or hardware fault. This triggers overload, retries, or synchronized actions in dependent services, leading to degraded performance, data inconsistencies, and further failures. Feedback loops, such as automated rollback attempts or cascading backoffs, can intensify the cascade if not properly controlled.

Impact and mitigation: Smittofall-oriented analysis helps assess systemic risk and plan resilience. Mitigations include strict change control, circuit breakers, rate limiting, graceful degradation, decoupled architectures, and robust incident response playbooks that isolate components and prevent simultaneous retries across services.

Examples and scope: The term is commonly discussed in the context of cloud-based microservices, distributed databases, and Internet of Things networks, where a single misconfiguration or attack can propagate rapidly. It is distinct from but related to general cascading failure and domino effect concepts.
