🛠️ How to Use

For New Table Creation

  1. Create table and enable RLS immediately:
CREATE TABLE my_new_table (...);
ALTER TABLE my_new_table ENABLE ROW LEVEL SECURITY;

  1. Choose appropriate template from docs/DATABASE_SECURITY_GUIDE.md:

    • User-Scoped Data (bookmarks, search history)
    • Public Read, Restricted Write (judges, courts)
    • Organization-Scoped Data (campaigns, resources)
    • Admin/Service Only (sync queues, audit logs)
    • Public Insert, Restricted Read (analytics events)

  2. Create policies using template:

-- Always include service role bypass
CREATE POLICY "Service role access" ON my_new_table
  FOR ALL TO service_role USING (true) WITH CHECK (true);

-- Add specific access pattern
CREATE POLICY "Users manage own" ON my_new_table
  FOR ALL TO authenticated
  USING (user_id = auth.uid());
  1. Test policies:
SET ROLE anon;
SELECT * FROM my_new_table; -- Should fail or return limited data
RESET ROLE;

How to Apply the Migration

Local Development

# Reset database (applies all migrations)
supabase db reset

# Or apply specific migration
supabase db push

Staging Environment

# Push to staging
supabase db push --project-ref <staging-project-id>

# Verify
psql -f scripts/verify_database_security.sql

Production Environment

# IMPORTANT: Test in staging first!

# Push to production
supabase db push --project-ref <production-project-id>

# Verify immediately
psql -f scripts/verify_database_security.sql

# Monitor for access denied errors in application logs

How to Run Verification

Quick Check

# Run full verification script
psql -f scripts/verify_database_security.sql

Manual Queries

-- Check RLS enablement (should return 0 rows)
SELECT tablename FROM pg_tables
WHERE schemaname = 'public' AND rowsecurity = false;

-- Check policy coverage (should return 0 rows)
SELECT t.tablename
FROM pg_tables t
LEFT JOIN pg_policies p ON p.tablename = t.tablename
WHERE t.schemaname = 'public'
  AND t.rowsecurity = true
GROUP BY t.tablename
HAVING COUNT(p.policyname) = 0;

-- Check function protection
SELECT proname, proconfig
FROM pg_proc p
JOIN pg_namespace n ON p.pronamespace = n.oid
WHERE n.nspname = 'public' AND p.prosecdef = true;

Supabase Dashboard

  1. Go to Supabase Dashboard
  2. Navigate to Database > Advisors
  3. Check for security warnings
  4. Expected: 0 warnings

How to Monitor

Weekly (Automated)

# Add to cron or CI/CD
0 0 * * 1 psql -f /path/to/verify_database_security.sql | mail -s "Weekly Security Report" team@example.com

Monthly (Manual Review)

  1. Run verification script
  2. Review security score
  3. Check for new tables without policies
  4. Update policies based on usage patterns
  5. Document any exceptions

Continuous (Real-time)

  • Monitor Supabase Dashboard > Database > Advisors
  • Set up alerts for security warnings
  • Track "access denied" errors in application logs
  • Review audit logs for suspicious activity

🔍 Troubleshooting

Issue: Access Denied Error

Symptom: Application can't access data Cause: Missing or too restrictive policy Solution:

  1. Check which table is affected
  2. Review policies: SELECT * FROM pg_policies WHERE tablename = 'table_name';
  3. Add missing policy or adjust USING clause
  4. Test with: SET ROLE authenticated; SELECT * FROM table_name;

Issue: RLS Not Enabled

Symptom: Verification shows table without RLS Cause: New table created without RLS Solution:

ALTER TABLE table_name ENABLE ROW LEVEL SECURITY;

-- Then create policies
CREATE POLICY "Service role access" ON table_name
  FOR ALL TO service_role USING (true) WITH CHECK (true);

Issue: SECURITY DEFINER Function Vulnerable

Symptom: Verification shows function without search_path Cause: Function created or altered without SET search_path Solution:

ALTER FUNCTION function_name() SET search_path = public, extensions;
