Jifunze best practices za usalama kwa Progressive Web Apps (PWA) ili kuhakikisha website/app yako inakuwa salama kwa watumiaji. PWA ni powerful, lakini ikiwa haijakingiwa ipasavyo, inaweza kuwa hatari. Hapa kuna mwongozo wa mambo muhimu ya kuzingatia.
Misingi ya Usalama kwa PWA:
HTTPS Lazima
PWA lazima ziwe served kupitia HTTPS ili Service Workers, Push Notifications, na Add to Home Screen ziweze kufanya kazi.
HTTPS inalinda data ya user dhidi ya interception na attacks za man-in-the-middle (MITM).
Content Security Policy (CSP)
Tumia CSP header kuzuia loading ya scripts, styles, au media zisizo salama.
Mfano:
Content-Security-Policy: default-src 'self'; script-src 'self' https://cdn.jsdelivr.net;
Service Worker Security
Hakikisha service-worker.js haikidhi requests zisizo salama.
Validate URLs kabla ya caching ili kuepuka cache poisoning.
Avoid caching sensitive data kama credentials.
Push Notification Security
Tumia VAPID keys za authentication.
Usitume sensitive info kwenye notification body.
Input Validation & Sanitization
Hii inahakikisha script injections (XSS) hazifanyiki kwenye forms au dynamic content.
Keep Dependencies Updated
Libraries za JS na frameworks lazima ziwe updated ili kuzuia vulnerabilities za outdated code.
Monitor & Test PWA
Tumia Lighthouse au tools nyingine za auditing kuona security issues.
Fanya regular penetration testing na vulnerability scanning.
Summary:
Kuzingatia HTTPS, CSP, service worker security, push notification authentication, input validation, na updates ni muhimu kuhakikisha PWA yako fast, reliable, na secure kwa watumiaji.
