FAQ & User Documentation
Everything an operator needs to run ARC Forensics — access, cases, evidence, storage, investigation, alerts, AI, reporting, retention and security.
Getting started
▸How do I sign in?
Open the Sign in page and use the workspace's managed identity options — Google or Microsoft — or the email and password account issued to you. Accounts are never self-service: a workspace administrator provisions every user.
▸What do the roles mean?
Admin — full control: manage users and invites, integrations, storage, retention, AI settings, and delete cases. Analyst — investigates: creates and edits cases, evidence, tasks, indicators, notes and reports, and runs AI requests. Viewer — read-only access to the shared investigation corpus.
▸How are new users added?
An admin sends an invite from Settings → Users. The invite email carries a secure activation link (valid 7 days) — the invitee chooses their own password; no initial password is ever generated or shared. Admins can resend or revoke invites, and change roles at any time.
▸Can I reset my password?
Yes — use "Forgot password?" on the sign-in page. A reset link is emailed to your address; opening it lets you set a new password. Invite and reset links both resolve to the same secure password page.
Command Center
▸What does the command center show?
A live operating picture: open incidents by severity and status, the alert queue, recent evidence, MITRE ATT&CK/ATLAS coverage, investigation activity and response metrics. Tiles and panels deep-link to the underlying registers.
Cases
▸How do I create a case?
Open the Case Register and use New Case. You set the title, severity, phase/status, classification, lead analyst, impacted hosts, priority, team, tags and SLA due date. Storage for the case (bucket/prefix and encryption key) is provisioned automatically.
▸Can I edit a case after it is opened?
Yes — the case screen has an Edit control covering the same metadata. Every update is recorded in the Investigation Activity log with a request id.
▸How are cases closed or deleted?
Cases move through triage, investigating, containment, eradication and recovery to closed — set via the case screen. Deleting a case is an admin action that removes the case and everything attached to it (evidence, custody, artifacts, timeline, indicators, notes, tasks, reports, activity and keys) and is audit-logged.
Evidence & chain of custody
▸What does evidence intake require?
A case and a payload file are both required. The file is hashed with SHA-256 before it is accepted; the hash is written to the evidence record before the object is stored, so integrity is established at ingest.
▸Is evidence encrypted at rest?
Yes. Evidence is envelope-encrypted with AES-256-GCM (the ARC1 format) using a per-case key before it is written to storage. On upload the workspace verifies the stored copy by reading it back, decrypting and re-hashing it — the evidence record's integrity flag reflects that check.
▸What is the chain of custody?
Every movement is a custody ledger entry: action, actor, role, location and optional hash verification. Records are appended when evidence is added, and analysts can add custody entries at any time from the Chain of Custody screen.
Storage
▸Where is evidence stored?
Administrators choose a backend in Settings → Storage: a Wasabi S3-compatible object store or a local network filesystem share. Each case gets its own bucket/prefix and is provisioned automatically, with status shown on the case.
▸How are encryption keys managed?
Keys are per case, never shared. In SSE-C mode the key is held in the workspace database (masked, admin-only); admins can rotate a case key, which re-encrypts safely via read-decrypt-rewrite with verification.
▸How do I test the storage connection?
Settings → Storage → Test connection validates the endpoint, credentials and reachable bucket and reports detailed, non-secret diagnostics.
Investigating
▸What investigation tools are available?
The Artifact Explorer (hosts, users, hashes, IPs, domains, files), Timeline Explorer (correlated events), IOC Correlation (indicators with hits, confidence and case links) and ATT&CK/ATLAS Coverage (including AI/ML techniques). Evidence Search spans the vault with filters.
▸How do I add or edit indicators?
From a case's Indicators tab or the IOC Correlation register: value, artifact type, severity, confidence, status, source, label, ATT&CK technique and tags. Edits are logged to the activity stream.
Alert connectors
▸Which alert sources are supported?
Bitdefender GravityZone, Tenable, Microsoft Azure Defender/Sentinel, Microsoft 365 Defender, Datto RMM and NinjaOne. Alerts are normalized, deduplicated and can be triaged into cases.
▸Who can see alerts from an integration?
Admins, plus any responder explicitly granted scope on that integration source (Settings → Alert integrations). Manual alerts are visible to all responders.
Tasking, notes & reports
▸How does tasking work?
Tasks can be created from the case screen or Response Tasking, assigned to a provisioned user, given a phase, priority and due date, and linked to evidence. Status moves Todo → In Progress → Done (or Blocked); overdue tasks are highlighted and the list sorts by due date.
▸What report options exist?
New Draft supports executive, technical, forensic and lessons-learned types with author, title and summary; reports can auto-fill from the case. Open Full Report assembles scope, timeline, evidence, custody, indicators, tasks and notes into a generated document you can download as Markdown or print.
AI decision engine
▸How does AI work in ARC Forensics?
The decision engine sends bounded context — never the full dataset — to a decision endpoint you configure. It supports alert triage dispositions, case guidance and IOC correlation. Bring-your-own-AI: each deployment supplies its own HTTPS endpoint; no shared AI service is provided and nothing is sent until an admin configures and enables it.
▸What happens to the suggestions?
Low-risk alert actions (severity, assignee) at or above the confidence threshold are auto-applied and recorded. Everything else lands in the AI Review Queue, where analysts see confidence, extracted signals and step-by-step rationale, then apply or reject — individually or in bulk. Every decision is traced by request id in the decision ledger.
▸How do I test the endpoint?
Settings → AI decision engine → Test endpoint runs a full health check: reachability, auth validation, latency and response-schema validation, with per-component status shown on the panel. Exports of the ledger (CSV/JSON) are available with filters for status, type, case and time range.
Retention & audit
▸How long are logs kept?
The admin audit log and the Investigation Activity log have a configurable retention (minimum 3 months) set by an admin in Settings → Retention. A background scheduler purges expired entries; the admin panel shows the last purge run, deletion counts and a preview of what would be purged.
▸Can I export the logs?
Yes — admins can export the audit log and activity log as CSV or JSON (limited to 5,000 rows) for incident review; exports are themselves audit-logged.
Security & privacy
▸Who can see data before sign-in?
Nobody. All workspace routes are gated: before authentication you only see the sign-in screen. Data access is enforced by row-level security with admin/analyst/viewer roles; integrations and settings are admin-only.
▸How are secrets handled?
Storage and integration credentials are stored server-side, masked in the UI and never returned to clients — the UI only ever shows whether a credential is set. Evidence payloads are encrypted before leaving the workspace, and there is no client-facing decrypt or download endpoint for evidence objects.
