25.1 Wi-Fi Security Standards
Wi-Fi chi suraksha varshanuvarshe sudharat geli, karan june standards todle gele.
| Standard | Introduced (approx.) | Status | Note |
|---|---|---|---|
| WEP | 1999 | Broken | Crackable in minutes; never use |
| WPA | 2003 | Weak | A stopgap over WEP hardware |
| WPA2 | 2004 | Common | Strong with a good passphrase; AES-CCMP |
| WPA3 | 2018 | Best | Resists offline cracking (SAE); use if your devices support it |
Home Wi-Fi usually uses a pre-shared key (PSK) – the passphrase everyone types. Companies use WPA2/WPA3-Enterprise, where each user logs in with their own credentials through a RADIUS server (no shared password).
Ravindra Bagale's Tip
Router madhe ajun "WEP" kiwa "WPA" disat asel tar lagech WPA2 kiwa WPA3 var badla. WEP fakt kahi minitat todla jato – to suraksha nahi, fakt bhas aahe. Ani "mixed WPA/WPA2" peksha shuddha WPA2/WPA3 nivada.
Practice task
Log in to your own home router's admin page and note which Wi-Fi security it uses. In your notes, write whether it should be upgraded and to what.
