Business Email Compromise (BEC)
CONCEPT
CYBERSECURITY
Email fraud using spoofed or hijacked accounts of executives, vendors or partners to redirect payments, change bank details or obtain sensitive data.
CONCEPT
SYSTEMS ARCHITECTURE
Event-Driven Architecture
A design approach in which components produce, detect, and respond to events representing changes or occurrences in a system.
BUSINESS RELEVANCE
EDA can reduce coupling, improve responsiveness, and let multiple processes react to the same business event. It supports scalable integration and near-real-time automation.
IMPLEMENTATION EXAMPLE
When an order is confirmed, an event triggers inventory reservation, customer notification, analytics, and fulfillment independently rather than through one synchronous chain.
LIMITATIONS
Asynchronous systems are harder to trace, test, and reason about. Duplicate, delayed, or out-of-order events are normal design concerns, and eventual consistency may not suit every process.
TECHNICAL EXPLANATION
Producers publish events without directly controlling consumers. Brokers, streams, or queues distribute them to interested services, which react asynchronously. Designs must address event contracts, delivery guarantees, ordering, idempotency, schema evolution, retries, and observability.
