Incidents are attack paths through identities, hosts and tools — yet many war rooms still brief from a linear ticket thread that hides lateral movement. EDR alerts, identity logs and firewall events arrive in different consoles. Responders paste hostnames into Slack and hope the next person understands blast radius. When executives ask who could still be affected, the answer depends on who last updated the shared doc — which is already wrong. linkchart maps the incident as a living attack graph: persons, company assets, phones, items (malware, keys) and events linked by authenticated as, pivoted to or exfiltrated from. Shift handovers point at the canvas, and containment priorities become visible.
Why a real link chart for incident response
Most people start this work with tools that were never designed for networks. Documents narrate. Spreadsheets tabulate. Whiteboards photograph poorly and refuse to scale. A dedicated incident response attack map approach treats every person, place, asset and event as a node — and every meaningful connection as an edge you can label, question and revise.
That shift matters because decisions in incident response are rarely about a single record. They are about patterns: who introduces whom, which address keeps appearing, which phone bridges two clusters, which event changed the shape of the network. linkchart exists so those patterns stay visible while you work, not only in the final slide.
Security teams looking for an incident response attack map, cyber link chart or lateral-movement diagram need a shared visual model of identities and assets. linkchart.art provides that model with structured cards and labelled edges for live response.
Who this map is for
SOC analysts, IR leads, and threat hunters reconstructing attack paths across identities, hosts, and tooling.
The signature move on the canvas: Draw the intrusion as a path of authenticated actions — account to host to tool to objective — so containment targets the real choke points.
What belongs on the map
Every incident response attack map gets noisy when the wrong things dominate the board. Prioritise these domain-specific anchors before decorative extras:
- User accounts and service principals
- Hosts, IPs, and cloud resources
- Malware families and tools
- Detection events and dwell milestones
Sample relationship labels
Prefer short, scannable edge text. Useful starters for this domain include: authenticated to, executed on, lateral move to, exfiltrated via, phished, persisted on.
Your first week on this canvas
Start from the first high-confidence alert and walk forward and backward. Add account and host cards before speculative threat-actor lore. Label each edge with technique or evidence ID. Midweek, mark contained versus still-trusted assets. Close the week with a path diagram leadership can use for impact and next containment steps without reading the full ticket dump. Document why each card earned its place so the incident response board does not drift into decoration. Before the week closes, freeze a viewer link for one outsider and capture their first three questions as backlog edges or notes.
What not to do
Do not decorate the map with unverified APT mythology. Avoid merging similar hostnames without asset inventory proof. Never leave containment status only in chat while the chart still shows a clean network. Resist one eternal map for every incident — split major waves. If an edge cannot be explained in one plain sentence, it is not ready for a briefing view of your incident response map.
What success looks like
A good IR chart shortens war-room debates: you can point at the bridge account, the beachhead host, and the egress path. Post-incident reviews inherit a timeline-shaped network instead of a folder of screenshots. When someone new opens the incident response canvas, they should grasp the live question, the strongest links, and the next check within minutes. That is the operational definition of a successful incident response attack map on linkchart.
How to use linkchart for incident response
You do not need a special template to begin. Open the linkchart app, create a map, and build outward from the question you must answer. The workflow below is a proven path for people doing incident response who want speed without losing structure.
- Open an incident map with the severity and ticket ID in the title.
- Add patient-zero assets and identities first, then expand along confirmed pivots only.
- Label edges with technique or evidence references your IR notes already use.
- Attach malware samples, API keys or stolen cookie sets as item cards.
- Log containment actions as events so the response timeline sits beside the graph.
- Give executives a simplified viewer cluster focused on business impact entities.
As the map grows, resist the urge to make it decorative. Beauty comes from clarity: consistent card titles, honest labels, and notes that explain uncertainty. A slightly ugly accurate chart beats a pretty misleading one every time — especially when incident response work has consequences.
Entity types that shine for this use case
linkchart supports investigation-ready cards you can reuse across domains. For incident response, start with these and expand only when a new type earns its place on the canvas:
Person Company Event Phone Address Vehicle
Person and organisation cards carry identity. Addresses anchor geography. Phones and communication profiles expose bridges between clusters. Events give you time. Vehicles and items capture the physical world that incident response narratives often depend on. Together they form a vocabulary you can teach a teammate in minutes.
Real-world scenarios
Business email compromise with finance fraud
An executive mailbox rules rewrite is the first event. Person cards for the executive and the finance approver link to company payment systems; phone cards capture MFA fatigue prompts. Item cards for the forged invoice and the attacker’s lookalike domain sit on the money path. When treasury asks whether other approvers are exposed, the map shows identity edges already checked versus still unverified — containment stops being a gut call.
Ransomware lateral movement
Initial access on a VPN account fans into three file servers and a backup console. Hosts as company/item cards, admin persons, and event cards for each encryption wave form a path. Seeing that backups share a credential with a jumped host changes the restore order immediately. Night-shift responders inherit a graph instead of a wall of alert IDs. Executives receive a simplified impact cluster while responders keep the host-level path on the working board.
Third-party SaaS token theft
A contractor’s integration token touches production data. Mapping the vendor company, the contractor person, the token item and the systems accessed clarifies whether the blast radius is one workspace or many. Event cards for token creation and last use sit next to revocation actions. Legal and IR finally share one picture of who must be notified. Post-incident reviews reuse the final graph so lessons learned are about real edges, not reconstructed memory.
Across these scenarios the constant is the same: when incident response information stays trapped in siloed files, people argue about memory. When it lives as a labelled network, people argue about evidence — which is exactly where productive work happens.
Field practices that keep maps trustworthy
- Mirror your MITRE-oriented notes in edge labels without turning the map into jargon soup.
- Keep ‘suspected’ and ‘confirmed’ compromise as distinct statuses.
- Group by trust zone — identity, endpoints, cloud — for executive readability.
- Update the map at each major containment milestone, not only at close.
Common pitfalls
- Do not draw every noisy alert as a node — only entities that change decisions.
- Avoid mixing unrelated incidents on one canvas during an active response.
- Never paste raw secrets, private keys or full token values into shared cards.
Compared with slides, whiteboards and generic diagram tools
Slide software is excellent for presenting a finished argument and poor at hosting an evolving network. Whiteboards are wonderful for a one-hour workshop and hostile to long-running incident response work. Generic diagrammers can draw boxes and arrows, yet they rarely treat investigative entities as structured records with fields your team actually fills in. linkchart sits in the gap: fast enough for a working session, structured enough for a case file, visual enough for a briefing.
FAQ: Incident response
Is this a replacement for our SIEM?
No. SIEMs detect and store telemetry. linkchart explains relationship and blast radius for humans in the war room.
Can we reuse maps across incidents?
Reuse asset inventories carefully; keep each incident’s attack path on its own map to preserve clarity.
How do we brief non-technical leaders?
Create a simplified cluster of business entities and impact events, hiding host-level clutter behind the full IR map.
Does it help with post-incident reviews?
Yes. The final graph plus containment events becomes a precise PIR artefact instead of reconstructed memory.
