What this card says
What it is
Wi-Fi security standards, from weak to strong: WEP (broken), WPA, WPA2, WPA3.
Home vs company
Home Wi-Fi uses one shared passphrase (PSK).
Companies use WPA2/WPA3-Enterprise, where each user logs in through a RADIUS server, with no shared password.
Why it matters for security
Older standards were broken, so newer ones replaced them.
Use WPA3, or WPA2 with a long passphrase.
| Standard | Introduced (approx.) | Status |
|---|---|---|
| WEP | 1999 | Broken |
| WPA | 2003 | Weak |
| WPA2 | 2004 | Common |
| WPA3 | 2018 | Best |
