In cloud security, real-time events provide immediate signals about system activities, which differ from traditional log files that require time to process.
Logs are retrospective—they require collection, storage, and analysis, which can introduce delays in threat detection. Events, however, enable immediate responses, reducing the time between detection and action.
Attackers can exploit gaps in security monitoring if alerts are delayed. Using events allows security teams to act in near real-time, preventing or mitigating potential threats before damage is done.
Why can’t we just process logs faster? Log storage and analysis introduce infrastructure and computational overhead.
What is EventBridge? A service that allows AWS resources to react to event patterns in real time.
Why is it useful? Security Hub findings, GuardDuty alerts, and CloudTrail logs generate security events that can be acted upon immediately when routed through EventBridge.
Events are like salmon jumping out of a river: if you don’t catch them when they appear, they’re gone (ephemeral).
