Plan d'execution des phases (0 a 6)

Phase 0 -- Baseline et inventaire (Complete)

Objectif : Creer une baseline precise et eliminer les angles morts.

• Inventaire des endpoints (public/admin) -- 176+ endpoints identifies
• Inventaire des mecanismes auth/session -- 2 systemes : Legacy + Multi-tenant

• Inventaire des secrets/variables d'environnement -- 67 variables, score 62/100
• Inventaire des dependances et pipeline de build -- 29 outdated, 0 CVE
• Cartographie de la surface d'attaque
• Backlog initial des findings -- 30 findings identifies
• Baseline de couverture des tests -- ~5% couverture (critique)

Phase 1 -- Hardening securite immediat (95% complete)

Objectif : Reduire les risques critiques rapidement sans casser le comportement existant.
