Endpoint Process-Tree Analysis: From Alert to Behavior
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.
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.
Before you begin
You will get more from this course if these foundations are already familiar.
- 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.
Course content
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.
Build a Trustworthy Process Lineage
Use process creation records to connect parents and children while respecting host, time, provider, and identifier limits.
Parse Command Lines as Structured Evidence
Separate executable, switches, values, code, paths, destinations, and quoting so suspicious strings are interpreted in the program’s own grammar.
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.
Baseline Parent-Child Relationships Without Freezing the Environment
Measure execution by device role, user role, software, version, and time so rare does not become synonymous with malicious.
Analyze Signed System Binaries by Behavior
Investigate proxy execution and dual-use utilities without assuming a valid signature makes the command trustworthy or the filename makes it malicious.
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.
Fuse Process, File, Network, Registry, and Identity Evidence
Build a time-aligned behavior timeline that distinguishes process creation from the files, connections, persistence, and account effects that follow.
Disposition, Containment, and Detection Handoff
Decide what the chain represents, preserve the evidence needed for response, and turn durable behavior into a testable detection improvement.
