Cyber Incidents & Offender Methods Technical Explainer

Is this a source record, security alert, incident ticket, intelligence report or somebody's summary?¶

They are different layers of information, and each can support a different kind of conclusion.

The simplest way to think about it is:

systems record events; tools detect patterns; responders build incidents; analysts and intelligence products interpret what those records may mean.

Follow the information back towards the source¶

Source recordWhat did the system record?Authentication, process, file, network or application event.

AlertWhy was attention drawn to it?A rule, threshold or model matched the underlying events.

Incident ticketHow did responders understand and handle it?Reports, hypotheses, actions and decisions accumulate over time.

Summary / intelligenceWhat interpretation was made later?Human analysis across one or more sources.

Each layer can be useful without replacing the one below it.

Source records tell you what the system observed¶

Examples include:

authentication events;
process execution;
file access;
firewall connections;
cloud audit events;
email message traces.

These are often the best place to test a technical claim.

They still need interpretation, but they are closer to the event itself.

Alerts tell you why something was noticed¶

An alert might say:

“Suspicious PowerShell activity detected”

That does not mean the alert itself proves malicious intent.

It means the product detected activity that matched a rule or model.

Useful questions are:

which source records triggered it;
what rule or threshold was applied;
whether the action was blocked;
what else happened around it.

What underlying records support an alert? is the useful next step when an alert matters.

Incident tickets are working records¶

A ticket may combine:

user reports;
alerts;
analyst notes;
containment decisions;
changing hypotheses;
recovery activity.

That history can be extremely valuable, especially for explaining why systems changed during the response.

But an early hypothesis in the ticket should not silently become a confirmed fact just because it was written down first.

Intelligence and summaries sit further from the event¶

An intelligence report may say an IP address, malware family or technique resembles activity seen elsewhere.

That may help with context or prioritisation.

It does not automatically identify the actor in this incident.

Likewise, an analyst summary can be excellent if the reasoning is clear and the underlying records remain traceable.

Keep observation and interpretation separate¶

For an important conclusion, try to be able to say:

what the system recorded;
what tool or person interpreted it;
what conclusion was drawn; and
what alternative explanations were considered.

The practical point is: know which layer you are relying on. Alerts, tickets and summaries help you navigate the incident; source records show what the systems actually observed.
