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
If your router still shows "WEP" or "WPA", switch to WPA2 or WPA3 right away. WEP can be broken in a few minutes – it is not security, only an illusion of it. And choose pure WPA2/WPA3 rather than "mixed WPA/WPA2".
Ravindra Bagale's Tip – मराठी
Router मध्ये अजून "WEP" किंवा "WPA" दिसत असेल तर लगेच WPA2 किंवा WPA3 वर बदला. WEP फक्त काही मिनिटांत तोडला जातो – ती सुरक्षा नाही, फक्त भास आहे. आणि "mixed WPA/WPA2" पेक्षा शुद्ध WPA2/WPA3 निवडा.
Ravindra Bagale's Tip – हिंदी
Router में अभी भी "WEP" या "WPA" दिखता है तो तुरंत WPA2 या WPA3 पर बदलो. WEP कुछ ही मिनटों में टूट जाता है – वह सुरक्षा नहीं, सिर्फ़ भ्रम है. और "mixed WPA/WPA2" के बजाय शुद्ध WPA2/WPA3 चुनो.
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.
