How to Build a Security Monitoring with Lovable

1Create a security monitoring app with Supabase. Set up these tables:
2
3- security_events: id, org_id, source (text, e.g. 'app'|'firewall'|'auth'), event_type (text), severity ('critical'|'high'|'medium'|'low'|'info'), title (text), description (text), raw_payload (jsonb), ip_address (text), user_id (uuid nullable), incident_id (uuid nullable references incidents), created_at (timestamptz default now())
4
5- incidents: id, org_id, title, severity ('critical'|'high'|'medium'|'low'), status ('open'|'investigating'|'contained'|'resolved'), assignee_id (uuid references auth.users), description (text), resolution_notes (text), created_at, updated_at, resolved_at (nullable)
6
7Create indexes:
8- security_events(org_id, created_at DESC)
9- security_events(severity, created_at DESC)
10- incidents(org_id, status, created_at DESC)
11
12Enable RLS on both tables. Only users with role = 'security_team' or 'admin' in profiles can access these tables.
13
14Enable Supabase Realtime on security_events.
15
16Seed with 50 sample security_events of mixed severities spanning the last 7 days.

1Build a ThreatCharts component at src/components/security/ThreatCharts.tsx.
2
3Requirements:
4- Fetch a daily severity breakdown: query security_events, group by date_trunc('day', created_at) and severity for the last 14 days. Use a Supabase RPC function get_event_counts(start_date, end_date) that returns rows of { day, critical, high, medium, low, info }.
5- Fetch event type distribution: query security_events, group by event_type, count, for the same period.
6- Left chart (2/3 width on desktop): StackedBarChart with one Bar per severity level, each with its corresponding color. XAxis shows dates formatted as 'MMM d'. Tooltip shows counts per severity.
7- Right chart (1/3 width): PieChart with one slice per event_type. Show top 8 types, group the rest as 'Other'. Use a Legend below the chart.
8- Add a period selector (7d / 14d / 30d) above the charts that re-fetches both datasets.
9- Show Skeleton loaders while fetching.

1Build an IncidentsTable component at src/components/security/IncidentsTable.tsx.
2
3Requirements:
4- Fetch incidents from Supabase ordered by created_at DESC
5- TanStack Table v8 columns: Title, Severity (Badge), Status (Badge: open=red, investigating=orange, contained=yellow, resolved=green), Assignee (Avatar + name), Created, Age (days since created_at)
6- Row click opens an IncidentDetailSheet:
7  - Title (editable Input)
8  - Severity Select
9  - Status Select with only valid transitions: open→investigating, investigating→contained, investigating→resolved, contained→resolved
10  - Assignee Select (list all security_team profiles)
11  - Description Textarea
12  - Resolution Notes Textarea (shown only when status is 'resolved' or 'contained')
13  - Linked Events section: show security_events where incident_id = this incident's id
14  - 'Link Event' Button: opens a Dialog to search and link unassigned events
15  - Save Button: calls supabase.from('incidents').update()
16- Create Incident Button above table: opens a Dialog with title, severity, description. On submit, inserts a new incident row.

1Create a Supabase Edge Function at supabase/functions/ingest-security-event/index.ts.
2
3Requirements:
4- Accept POST requests with Content-Type: application/json
5- Verify authentication: check Authorization header matches 'Bearer ' + Deno.env.get('WEBHOOK_SECRET'). Return 401 if invalid.
6- Accept a flexible JSON body with these fields (normalize as needed):
7  { source, event_type, severity, title, description, ip_address, user_id, raw_payload }
8- Validate: severity must be one of critical|high|medium|low|info. Return 400 with error details if invalid.
9- Insert into security_events using the Supabase service role client (use Deno.env.get('SUPABASE_URL') and Deno.env.get('SUPABASE_SERVICE_ROLE_KEY'))
10- Set org_id from a hard-coded default org or from an X-Org-ID header
11- Return { id: insertedId, created_at } on success
12- Add CORS headers
13- Log errors to console for Supabase Edge Function logs visibility
14
15Also build a WebhookConfigCard component in Lovable that displays the deployed Edge Function URL and the WEBHOOK_SECRET (masked) so admins know where to point their external tools.

1Add alert threshold monitoring to the dashboard.
2
3Requirements:
4- Create an alert_thresholds table in Supabase: id, org_id, severity ('critical'|'high'), threshold_count (integer), window_minutes (integer default 10), created_at. RLS: security team members can read/write their org's thresholds.
5- Build an AlertThresholdMonitor component:
6  - Subscribe to the same security_events Realtime channel
7  - Maintain a rolling buffer of events from the last window_minutes
8  - On each new event, count events matching the severity in the buffer
9  - If count >= threshold_count, call sonner's toast.error() with: 'ALERT: X critical events in the last Y minutes' and a View Events Button that scrolls to the feed
10  - Debounce alerts: don't re-fire the same severity alert more than once per minute
11- Add an AlertSettings Dialog accessible from a Bell icon in the header:
12  - Shows current thresholds for critical and high severity
13  - Allows changing threshold_count and window_minutes
14  - Saves to the alert_thresholds table
