In dit document wordt beschreven hoe ISE en Windows-aanvrager kunnen worden geconfigureerd voor Extensible Authentication Protocol (EAP) Chaining met TEAP.
Cisco raadt kennis van de volgende onderwerpen aan:
ISE
Configuratie van Windows Supplicant
De informatie in dit document is gebaseerd op de volgende software- en hardware-versies:
De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u zorgen dat u de potentiële impact van elke opdracht begrijpt.
TEAP is een op tunnels gebaseerde Extensible Authentication Protocol-methode die een beveiligde tunnel tot stand brengt en andere EAP-methoden uitvoert onder de bescherming van die beveiligde tunnel.
TEAP-verificatie vindt plaats in twee fasen na de eerste uitwisseling van EAP-identiteitsverzoeken en -antwoorden. In de eerste fase gebruikt TEAP de TLS-handdruk om een geverifieerde sleuteluitwisseling te bieden en een beveiligde tunnel te creëren. Zodra de tunnel tot stand is gebracht, begint de tweede fase met de peer en de server die verder praten om de vereiste authenticaties en autorisatiebeleid vast te stellen.
Cisco ISE 2.7 en hoger ondersteunt het TEAP-protocol. De TLV-objecten (type-length-value) worden binnen de tunnel gebruikt om verificatiegerelateerde gegevens tussen de EAP-peer en de EAP-server te vervoeren. Microsoft introduceerde ondersteuning voor TEAP in Windows versie 10 2004 uitgebracht in mei 2020.
Met EAP-chaining kunnen de gebruiker en de machine binnen één EAP/Radius-sessie worden geverifieerd in plaats van twee afzonderlijke sessies. Om dit te bereiken, moet u de Cisco AnyConnect NAM-module hebben en EAP-FAST op de Windows-aanvrager gebruiken, omdat de oorspronkelijke Windows-aanvrager dit niet ondersteunde. Nu kunt u de Windows Native Supplicant gebruiken om EAP Chaining met ISE 2.7 uit te voeren met behulp van TEAP.
1. U moet de Toegestane protocollen bewerken om TEAP- en EAP-ketting in te schakelen.
2. Navigeer naar ISE > Beleid > Beleidselementen > Resultaten > Verificatie > Toegestane protocollen > Nieuw. toevoegen Schakel de selectievakjes TEAP en EAP aan.

3. Maak een certificaatprofiel en voeg dit toe aan de reeks Identiteitsbronnen.
4. Navigeer naar ISE > Beheer > Identiteiten > Identiteitsbronreeks en kies het Certificaatverificatieprofiel.

5. U moet deze volgorde aanroepen in het verificatiebeleid.
6. Navigeer naar ISE > Beleid > Beleidssets. Choose the Policy Set forDot1x > Verificatiebeleid en kies de identiteitsbronreeksen die in stap 3 zijn gemaakt.

7. Nu moet u het machtigingsbeleid wijzigen onder de Dot1x-beleidsset.
8. Navigeer naar ISE > Beleid > Beleidssets. Kies de Beleidsset voor Dot1x > Verificatiebeleid. Je moet twee regels opstellen. De eerste regel controleert of de machine is geverifieerd, maar de gebruiker niet. De tweede regel controleert of zowel de gebruiker als de machine nu zijn geverifieerd.

9. Hiermee wordt de configuratie aan de kant van de ISE-server voltooid.
Configureer de bekabelde verificatie-instelling in dit document.
1. Navigeer naar Configuratiescherm > Netwerkcentrum > Adapterinstellingen wijzigen en klik met de rechtermuisknop op LAN-verbinding > Eigenschappen. Klik op het tabblad Verificatie.
2. Klik op de vervolgkeuzelijst Verificatie en kies Microsoft EAP-TEAP.

3. Klik op de Settings knop naast TEAP.

4. Kies onder Client Authentication de EAP-methode voor verificatie aan Microsoft: smartcard van ander certificaat.
5. Klik voor elke vervolgkeuzelijst voor de EAP-methode op de knop Configureren en wijzig deze aan de vereisten en klik op OK.

6. Klik op de aanvullende instellingen knop aan de onderkant.

U kunt het Windows 10-systeem opnieuw opstarten of u kunt zich afmelden en vervolgens inloggen. Wanneer het inlogscherm van Windows wordt weergegeven, wordt de systeemverificatie geactiveerd.
In de live logs ziet u anoniem, host / beheerder (in dit voorbeeld wordt de systeemnaam weergegeven) in het identiteitsveld. U ziet anoniem omdat u de aanvrager hierboven hebt geconfigureerd voor identiteitsprivacy.
Wanneer u inlogt op de pc met referenties, ziet u de live-logs als Administrator@example.local, host / beheerder. Dit is EAP-chaining waarbij zowel gebruiker- als machineverificatie plaatsvond in één EAP-sessie.

In de Live Log Details, de machine authenticaties tonen slechts een enkele NACRadiusUsername vermelding, maar de geketende gebruiker en machine authenticatie toont twee vermeldingen (een voor de gebruiker, en een voor de machine.) U ziet ook onder het gedeelte Verificatiedetails dat TEAP (EAP-TLS) werd gebruikt voor het verificatieprotocol. Als u MSCHAPv2 gebruikt voor machine- en gebruikersverificatie, wordt in het verificatieprotocol TEAP (Microsoft: Secured password (EAP-MSCHAP v2)) weergegeven.
