SIEM — The Signal Line: How the Alarm System Hears

A friendly first course on how an organisation hears its own systems — every action leaves a trace, traces travel to one listening post, rules turn them into questions, and people give the questions meaning.

What you'll learn

• Explain log lines, the three jobs of the trail (replay, watch, prove), and why scattered diaries must travel to one listening post on one clock.
• Describe a SIEM plainly — collect, normalise, store, watch — and recognise correlation: the meaning that lives between diaries, needing human context to resolve.
• Hold the keystone that an alert is a question, never a verdict, and understand the noise economics — false alarms budgeted, fatigue as a property of the queue, tuning as a standing loop in both directions.
• Name the senses that fail quietly (coverage gaps, drifted clocks, short memory), follow an alert through triage to calm escalation, and practise the four-line card: senses on, questions answered, oddities reported, record untouched.
