Question

Accepted Answer

**Sarrafa jiyoyi** yana aiki da kiyaye masu amfani suka ci gida a cikin buƙatun - kuma yin hakan cikin karfi yana da muhimmanci, saboda rashin karfin jiyoyi (satar jiya, tsarawa jiya) yana bada damar masu hari su fakanci masu amfani. Jiyoyi masu karfi sun haɗa da adbawa daidai na alama, tsaron kuki, da sarrafar rayuwar jiya.

## Kina jiyoyi ke aiki

```text
After login, the server keeps a SESSION identifying the user across requests:
  → a SESSION ID (or token) is stored client-side (usually a cookie) and sent each request
  → the server uses it to know who the user is (without re-authenticating each time)
→ the session ID/token is effectively a key to the user's account → must be PROTECTED.
```

## Tabbatar da jiyoyi

```text
✓ SECURE COOKIE flags for session cookies:
  → HttpOnly → JavaScript can't read it (protects against theft via XSS)
  → Secure → sent only over HTTPS (not plaintext)
  → SameSite → not sent on cross-site requests (mitigates CSRF)
✓ Strong, RANDOM, unpredictable session IDs (can't be guessed)
✓ Store session data server-side (or sign/encrypt tokens); transmit over HTTPS only
```

## Rayuwar jiya da hari

```text
✗ SESSION HIJACKING → stealing a session ID to impersonate the user (via XSS, network
  sniffing) → prevent with HttpOnly, HTTPS, secure handling
✗ SESSION FIXATION → attacker sets a known session ID, then the victim logs in with it →
  prevent by REGENERATING the session ID on login (privilege change)
✓ EXPIRE sessions → timeouts (idle + absolute); INVALIDATE on logout (server-side)
✓ Regenerate IDs on login/privilege change; allow users to revoke sessions
```

Ana gani cewa sarrafar jiyoyi mai karfi yana muhimmanci saboda **jiyoyi suke kiyaye masu amfani an tabbatar, kuma rashin karfin jiyoyi yana ba da damar masu hari su fakanci masu amfani**, saboda haka adbawa a karfi yana da mahimmanci, yana ba da muhimmancin ilimin tsaro.

Bayan shigo, sulhu yana kiyaye jiya (ta hanyar ID jiya ko alama, sau da yawa a cikin kuki) don gano mai amfani a cikin buƙatun ba tare da sake adbawa - kuma saboda wannan ID jiya yana aiki azaman **mabuɗi ga asusu mai amfani**, kiyayewa yana da mahimmanci.

Ana gani cewa **tabbatar da jiyoyi** yana da muhimmanci: amfani da **alamu masu karfin kuki** don kukiyin jiya — **HttpOnly** (hana JavaScript karanta kuki, kiyaye daga satar ta hanyar XSS), **Secure** (aika kawai a hanyar HTTPS), da **SameSite** (ba aika a buƙatun gida-gida, sakewa CSRF) — amfani da **ID jiya mai karfi, bazuwa, maras lissafi**, kuma adbawa data jiya a karfi.

Wannan kariyoyi a kai-kai sukan kare alama jiya.

Ana gani cewa **rayuwar jiya da hari** yana da muhimmanci: **satar jiya** (satar ID jiya domin fakanci mai amfani, ana sakewa ta HttpOnly, HTTPS, da adbawa daidai), **tsarawa jiya** (masu hari suna saita ID jiya sannan nesu a jiya kafin mai amfani ya shigo, ana sakewa ta **sake buƙata ID jiya a shigo**), da sarrafar jiya daidai (tsallakewa jiya da lokaci, soke a samun shigo a sulhu, sake buƙata ID a sauyin karfi, da bada damar soke jiya.

Ana gani cewa sanin waɗannan hari da sakewansu yana da mahimmanci domin sakewa hari daga samun aikin jiyoyi na mai amfani.

Tun da jiyoyi suke kiyaye masu amfani an tabbatar kuma rashin karfin jiyoyi (satar, tsarawa) sukan bada damar fakanci asusu, kuma tun da sarrafar jiya mai karfi (alamu masu karfin kuki, ID masu karfi, sarrafa jiya daidai, sake buƙata a shigo) yana sakewa waɗannan, kuma tun da ganin shi yana da mahimmanci domin kiyaye masu amfani da aka tabbatar, sanin sarrafar jiya mai karfi yana da kima, haɗin gida-karfi ilimin tsaro — mahimmanci domin kiyaye jiyoyi da ke kiyaye masu amfani suka ci gida, kare daga hari na satar da tsarawa da ke ba da damar hari daga fakanci masu amfani, da mada muhimmanci domin kowane aikace-aikace da adbawa.
