Wireless Authentication
Cards in this deck (11)
- 1IEEE 802.1x1) EAPOL (Extensible Authentication Protocol over LAN)
2) Authentication mechanism
3) Port based security for wireless network access - 2Lightweight Extensible Authentication Protocol (LEAP)1) Cisco proprietary
2) Uses passwords only
2) No detailed certificate management
3) Based on MS-CHAP
(including MS-CHAP security shortcomings) - 3Protected Extensible Authentication Protocol (PEAP)1) Created by Cisco, Microsoft, and RSA Security
2) Encapsulates EAP in a TLS tunnel
3) Only one certificate needed, on the server - 4Wired Equivalent Privacy (WEP)1) 64-bit or 128-bit key size
2) Cryptographic vulnerabilities
3) WEP is no longer used
4) 24bit initialization vector size - 5WiFi Protection Access (WPA)1) Short-term workaround after WEP
2) Used RC4 cipher as a TKIP (Temporal Key Integrity Protocol)
3) TKIP has its own vulnerabilities - 6WiFi Protection Access 2 (WPA2)1) Replaced TKIP with CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol)
2) Replaced RC4 with AES (Advanced Encryption Standard)
3) WPA2 is the latest and most secure wireless encryption method
4) 802.11i - 7WiFi Protection Access 2 - WPA2 Enterprise1) WPA2-Enterprise adds 802.1x
2) RADIUS server authentication - 8Extensible Authentication Protocol (EAP)EAS-TLS, EAP-PSK, EAP-MD5
LEAP & PEAP - 9Wireless Transport Layer Security (WTLS)1) provides authentication, encryption, and data integrity for wireless devices.
- 10Wireless Application Protocol (WAP)1) Data transmission standard
2) Using WML Wireless Markup Language
3) WMLScript
4) WAP gateway system between HTTP and WAP with no encryption - 11Wireless Application Protocol (WAP)1) Technical standard
2) Used for accessing information over a mobile wireless network
3) WAP protocol Suite (WSP = session info, WTP = TCP&UDP, WTLS =sec layer, WDP = common interface btw devices)
