FAQ & User Documentation

Everything an operator needs to run ARC Forensics — access, cases, evidence, storage, investigation, alerts, AI, reporting, retention and security.

01

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.

02

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.

03

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.

04

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.

05

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.

06

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.

07

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.

08

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.

09

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.

10

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.

11

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.
