2812. **Ne zapuskuyte vid imeni root**: stvorit ne-root korystuvacha ta pereyddit na nyoho
2823. **Vykorystovuyte obrazy Alpine**: mensha poverkhnya ataky (mensha paketiv vstanovleno za zamovchuvannyam)
2834. **Fiksuite versiyi obraziv**: `node:22-alpine` zamist `node:latest` dlya zapobihannya atakam na lantsyuh postachannya
