## Descripció

SiteGuard Scanner is a companion plugin for the vulnerability diagnostic service
provided by EG Secure Solutions. Installing it on a site that is under a diagnostic
contract enables the following two features.

 1. **Site ownership verification (authentication)** — Lets the diagnostic service 
    confirm that the target site is the one that is actually under a diagnostic contract.
 2. **Installation inventory** — Provides the diagnostic service with a list of the
    plugins and themes installed on the target site (name, version, and activation 
    status).

#### How it communicates

The plugin only **responds to signed requests** sent by the diagnostic service. 
It never sends data to any external server on its own (it does not «phone home»).

 * Authentication uses an **HMAC-SHA256 signature** based on a shared token. Each
   request includes a timestamp and a nonce (a single-use random value) to prevent
   replay attacks.
 * Requests are received through the WordPress REST API endpoints `/wp-json/siteguard-
   scanner/v1/verify` and `/wp-json/siteguard-scanner/v1/collect`.
 * For environments where the REST API is disabled, a custom endpoint (`/?siteguard-
   scanner-request=verify` and `/?siteguard-scanner-request=collect`) is provided
   as a fallback.

Every endpoint responds only to requests carrying a valid signature. When signature
verification fails, the plugin returns HTTP 401 and no information at all.

#### Data provided

When responding to `collect`, the plugin returns the following information to the
diagnostic service:

 * Site URL
 * WordPress core version
 * List of installed plugins (slug, name, version, activation status, network-activation
   status)
 * List of installed themes (slug, name, version, activation status, network-enabled
   status)

No personal data, post content, or any other data beyond the above is collected 
or transmitted.

#### Multisite

On a multisite network, diagnostics are performed against the main (parent) site.
Because plugin and theme files are shared across the entire network, `collect` returns
the network-wide inventory of installed assets and correctly reports network-activated
plugins via the `network_active` flag.

## Captures

[⌊The settings screen (Settings > SiteGuard Scanner), where you enter the token 
provided by the diagnostic service.⌉⌊The settings screen (Settings > SiteGuard Scanner),

The settings screen (Settings > SiteGuard Scanner), where you enter the token provided
by the diagnostic service.

## Instal·lació

 1. In the WordPress admin, go to «Plugins» > «Add New».
 2. Click «Upload Plugin» at the top of the screen and select the plugin ZIP to install
    it.
 3. After installation, activate the plugin.
 4. Open «Settings» > «SiteGuard Scanner» in the admin menu.
 5. Enter the 64-character token provided by the diagnostic service and save.

On a multisite network, set the token on the main site’s Settings screen.

## PMF

### Does this plugin send data to an external service?

It does not send anything on its own. It only responds to signed requests from the
diagnostic service.

### I cannot save the token.

The token must be a 64-character lowercase hexadecimal string (0-9, a-f). Values
that do not meet these conditions are rejected and not saved.

### Can I use it even with the REST API disabled?

Yes. In environments where the REST API is disabled, the custom endpoint (`/?siteguard-
scanner-request=...`) is used automatically as a fallback.

### Does it work on multisite?

Yes. On multisite, diagnostics are performed against the main site, and the plugin
provides the network-wide plugin and theme inventory.
