## 📖 Usage

### Creating an IOC

1. Navigate to **Add IOC** from the menu
2. Select IOC type (IPv4, Domain, Hash, etc.)
3. Enter the IOC value
4. Set severity, confidence, and TLP level
5. Add description and tags
6. For hash types (MD5, SHA1, SHA256, etc.), optionally select a **target Operating System**
7. Choose a **Lifecycle Status**: *To be reviewed* (default), *Active*, or *Draft*
8. Click **Create IOC**

> IOCs created as **To be reviewed** are immediately placed in the approval queue and reviewers are notified.

### Enriching IOCs

Click **Enrich IOC** on any IOC detail page to automatically fetch threat intelligence:
- **IP addresses** — GeoIP location, ASN, and organization data
- **Hashes** — VirusTotal malware analysis, detection rate, MITRE ATT&CK techniques
- **URLs** — URLScan.io screenshot/verdict, VirusTotal URL analysis, HTTP headers, server fingerprinting, GeoIP of resolved IP
- **Domains** — WHOIS registration data, DNS records (A, AAAA, MX, NS, TXT), SSL/TLS certificates

Once enriched, the button changes to **Refresh IOC Enrichment** — clicking it clears the service cache and re-fetches fresh data from each source.

### Creating Relationships

Link related IOCs together:
1. Open an IOC detail page
2. Click **Add Relationship** in the Related IOCs section
3. Search for target IOC
4. Select relationship type (resolves_to, contains, downloads_from, etc.)
5. Add optional notes

The **Graph View** tab on the detail page visualizes the full relationship network with configurable hop depth (1–3).

### Generating YARA Rules

1. Open any IOC detail page
2. Click **Generate YARA**
3. Copy or download the rule (`.yar`)
4. Toggle to YARA-X syntax if needed (`.yarax`)

Supported for all IOC types: hashes (uses VT enrichment for additional hashes), IPs, domains, URLs.

### Generating Hunting Queries

1. Open any IOC detail page
2. Click **Hunting Queries**
3. Select a platform tab: **Splunk**, **KQL / Sentinel**, **Sigma**, or **CrowdStrike**
4. Copy to clipboard or download with the native file extension (`.spl`, `.kql`, `.yml`, `.fql`)

Queries use enrichment data where available (e.g. all known hashes from VirusTotal). Timeframe defaults to the last 30 days — adjust index names and table names for your environment.

### Commenting

Add comments to IOCs for collaboration:
- Use **Markdown** formatting for rich text
- **@mention** users to notify them
- **Reply** to create threaded discussions
- **Edit/Delete** your own comments

### Sharing IOCs

Click **Share** on any IOC detail page to copy an anonymized shareable link. The shared view strips sensitive metadata for safe external sharing.

### IOC Lifecycle Management

IOCs follow a structured approval workflow to ensure quality and accountability.

#### States

| State | Description |
|-------|-------------|
| **Draft** | Work in progress — only the creator and admins can see and edit it |
| **In Review** | Submitted for approval — reviewers are notified and can approve or reject |
| **Active** | Approved and operational — visible to all users |
| **Archived** | Retired — kept for historical reference, no longer active |

#### Workflow

```
Draft ──→ In Review ──→ Active ──→ Archived
            │                         ↑
            └─── (rejected) ──→ Draft   └─── Restore
```

#### For IOC Creators

1. Create an IOC — it defaults to **In Review** and reviewers are notified automatically
2. Alternatively, save as **Draft** to continue editing before submitting
3. On a Draft IOC, click **Submit for Review** when ready
4. Once approved, the IOC becomes **Active**
5. If rejected, the IOC returns to **Draft** with a rejection reason you can address

#### For Reviewers / Admins

1. A badge in the navbar shows the number of IOCs pending review
2. Navigate to **Approvals** in the top menu to see the full queue
3. On any IOC in review, click **Approve** to make it active or **Reject** with a reason
4. Reviewers can also **Archive** active IOCs and **Restore** archived ones

#### Marking for Review (quick path)

On any **Active** IOC detail page:
1. Toggle the **"To be reviewed"** switch
2. The lifecycle status automatically moves to **In Review** and reviewers are notified
3. Toggling it off restores the status to **Active**

#### Reviewer Role

The reviewer flag is independent of the user's role and can be granted to any user:
1. Navigate to **Admin → Reviewers**
2. Click **Grant** next to any user to give them reviewer privileges
3. Click **Revoke** to remove reviewer access

### Multi-Factor Authentication (MFA)

Enhance account security with optional TOTP-based two-factor authentication:

**Enabling MFA**:
1. Navigate to your profile page
2. Click **"Enable MFA"** in the Multi-Factor Authentication section
3. Scan the QR code with your authenticator app (Google Authenticator, Authy, Microsoft Authenticator)
4. Enter the 6-digit verification code to confirm setup
5. Save your 10 backup codes in a secure location (each can only be used once)

**Logging in with MFA**:
1. Enter your username and password as usual
2. You'll be redirected to an MFA verification page
3. Enter the 6-digit code from your authenticator app
4. Alternatively, check "Use a backup code instead" and enter one of your backup codes

**Managing MFA**:
- **View Backup Codes**: See how many backup codes you have remaining
- **Regenerate Codes**: Generate new backup codes if you've used most of them (requires MFA verification)
- **Disable MFA**: Turn off MFA protection (requires password + current MFA code)

**Security Features**:
- Rate limiting: Maximum 10 failed verification attempts per 15 minutes
- Session timeout: MFA verification must be completed within 5 minutes
- Backup codes: 10 one-time use codes for device loss scenarios
- Audit logging: All MFA events (enable, disable, login attempts) are logged
- Admin visibility: Admins can see which users have MFA enabled

**Note**: MFA is optional and configured per-user. Existing users are not affected when MFA is added to the system.
