JWT vs Session Auth: bezopasnaya autentifikatsiya API

Vybor mezhdu JWT (JSON Web Tokens) i Session-based autentifikatsiey kritichen dlya bezopasnosti API.

Session-based autentifikatsiya

Server hranit sessiyu, klient poluchaet session ID v cookie.

Plyusy:

• Mgnovennaya invalidatsiya
• Menshiy razmer payload
• Prostota realizatsii

Minusy:

• Trebuet shared storage dlya masshtabirovaniya
• CSRF-uyazvimost (reshaetsya tokenami)

JWT autentifikatsiya

Samodostatochnye tokeny s podpisyu. Stateless, masshtabiruemaya.

Plyusy:

• Masshtabiruemost bez shared storage
• Cross-domain avtorizatsiya
• Mikroservisnaya arhitektura

Minusy:

• Nevozmozhno otozvat do expiration
• Bolshoy razmer tokena
• Slozhnost refresh token flow

Best Practices

• Hranite JWT v httpOnly cookies, ne v localStorage
• Ispolzuyte korotkiy srok zhizni access token (15 min)
• Rotatsiya refresh tokens
• HTTPS only

Rekomendatsii

Dlya monolitnyh prilozheniy — Sessions. Dlya API i mikroservisov — JWT s pravilnoy realizatsiey.
