Reading estimates use lesson text and an allowance for diagrams. Reflection, exercises and optional linked resources take additional time. These are estimates, not measured completion times.

KNOW WHAT YOU’RE WORKING TOWARD

What you’ll learn

  • Reconstruct process lineage using host-scoped identifiers, time, image paths, users, and command lines.
  • Parse command arguments and execution context without treating strings or signatures as verdicts.
  • Compare a chain with role-aware baselines and analyze system-binary proxy behavior.
  • Fuse process, file, network, registry, identity, and persistence evidence into a scoped endpoint disposition.

Is this the right course for you?

Who it’s for

Analysts investigating endpoint alerts and process relationships.

Scope and boundaries

Process-tree evidence and behavioral reasoning. Product-specific response actions require separate authorization and validation.

How you’ll learn

Self-paced reading with explanatory diagrams and linked resources. Reflection and optional resource study take additional time.

Before you begin

  • Windows endpoint and alert-triage familiarity — Learners should recognize executables, paths, command-line arguments, users, hashes, and timestamps. Reverse engineering and malware-development experience are not required.

About this course

Process trees are among the fastest ways to understand an endpoint alert, but a parent-child diagram is not the incident by itself. This course teaches SOC analysts, threat hunters, and incident responders to reconstruct Windows process creation from Security event 4688 and Sysmon event 1; handle process IDs, GUIDs, command lines, users, tokens, hashes, and parent information correctly; build role-aware baselines; and analyze system binaries used for legitimate or harmful work. Learners correlate execution with files, network, registry, identity, and persistence, then write a disposition that separates observed behavior from technique labels. Completion means the learner can explain an execution chain, identify collection and causal limits, scope related activity, and recommend containment or tuning with evidence.

Course curriculum

MODULE 1

1. Reconstruct Execution Correctly

Learn what process-creation telemetry records, how identifiers behave, and how command-line structure changes the meaning of an execution chain.

  1. Build a Trustworthy Process LineageUse process creation records to connect parents and children while respecting host, time, provider, and identifier limits.3 min reading
  2. Parse Command Lines as Structured EvidenceSeparate executable, switches, values, code, paths, destinations, and quoting so suspicious strings are interpreted in the program’s own grammar.3 min reading

MODULE 2

2. Judge Behavior in Context

Compare chains with device and user roles, then analyze signed system utilities by what they cause rather than by reputation alone.

  1. Baseline Parent-Child Relationships Without Freezing the EnvironmentMeasure execution by device role, user role, software, version, and time so rare does not become synonymous with malicious.3 min reading
  2. Analyze Signed System Binaries by BehaviorInvestigate proxy execution and dual-use utilities without assuming a valid signature makes the command trustworthy or the filename makes it malicious.3 min reading

MODULE 3

3. Correlate Impact and Close the Case

Fuse endpoint and identity evidence into a behavior timeline, then choose containment, tuning, or escalation with a reproducible handoff.

  1. Fuse Process, File, Network, Registry, and Identity EvidenceBuild a time-aligned behavior timeline that distinguishes process creation from the files, connections, persistence, and account effects that follow.3 min reading
  2. Disposition, Containment, and Detection HandoffDecide what the chain represents, preserve the evidence needed for response, and turn durable behavior into a testable detection improvement.3 min reading
