Dépannage de CRL pour l'authentification basée sur certificat AnyConnect

Introduction

Ce document décrit comment dépanner la liste de révocation de certificats (CRL) configurée pour l'authentification basée sur les certificats AnyConnect.

Conditions préalables

Exigences

Cisco vous recommande de prendre connaissance des rubriques suivantes :

• Autorité de certification (CA)
• Infrastructures à clé publique (PKI)
• VPN RA sur FTD
• Windows 10 avec client AnyConnect

Composants utilisés

Les informations contenues dans ce document sont basées sur les versions de logiciel suivantes :

• CSR1000V - Cisco IOS® XE, version 16.12.03 - en tant que serveur Cisco IOS XE CA
• NGFWv - Version 7.1.0 - comme passerelle VPN
  
• AnyConnect Secure Mobility Client version 4.10.07073 - en tant que client VPN
• Windows 10 en tant qu'ordinateur local

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. Si votre réseau est en ligne, assurez-vous de bien comprendre l’incidence possible des commandes.

Informations générales

La liste de révocation de certificats permet aux périphériques de déterminer si un certificat a été révoqué avant l'expiration de sa durée de vie. Une liste de révocation de certificats contient le numéro de série et la date de révocation du certificat. Une passerelle sécurisée telle que les systèmes Firepower Thread Defense (FTD) ou d'autres périphériques finaux utilise cette fonctionnalité afin de renforcer l'authentification du certificat en validant l'état du certificat.

Topologie

Topologie de base qui fournit la connectivité à la passerelle VPN et au serveur AC.

Configuration importante

Afin d'accomplir l'authentification basée sur certificat avec CRL, la configuration présentée a été utilisée dans chacun des périphériques impliqués.

Routeur CA

L'autorité de certification du serveur est chargée de délivrer des certificats d'identité aux utilisateurs afin de fournir une authentification par rapport à la passerelle VPN. En outre, le routeur stocke le fichier de base de données CRL et agit en tant que point de distribution CRL (CDP).

Un CDP est l'emplacement où la passerelle VPN et d'autres utilisateurs finaux récupèrent les informations CRL. Ces informations sont mises en cache localement et ne sont valides que pendant une période spécifique ; lorsque cette période expire, une nouvelle liste de révocation de certificats est téléchargée.

Configuration de la passerelle VPN

Le FTD est configuré afin de fournir un VPN d'accès à distance aux utilisateurs finaux en utilisant des certificats comme méthode d'authentification (certificat uniquement). À la réception du certificat d'identité de l'utilisateur, le FTD vérifie si le certificat a été émis par une autorité de certification (CA) connue et confirme sa validité en obtenant la liste de révocation de certificats du CDP défini dans le certificat.

tunnel-group local type remote-access
tunnel-group local general-attributes
address-pool AC_pool
default-group-policy local_gp
username-from-certificate use-entire-name
tunnel-group local_test webvpn-attributes
authentication certificate
group-alias test enable

Périphérique Windows

Un certificat d'identité a été émis par le serveur AC et installé sur le périphérique Windows.

Validation

Les débogages et captures suivants affichent la différence entre un utilisateur utilisant un certificat valide (scénario de travail) et un utilisateur utilisant un certificat qui a été révoqué (scénario de non-travail).

Scénario 1. Le certificat est valide pour l'authentification

Lorsque l'utilisateur lance la tentative de connexion, il fournit au FTD son certificat d'identité, la passerelle VPN vérifie que l'émetteur est une autorité connue et commence à demander la liste de révocation de certificats à partir du CDP défini dans le certificat d'identité via une requête HTTP/GET. Le serveur AC répond avec la liste de révocation de certificats et le FTD vérifie si le numéro de série du certificat est répertorié. Comme la liste de révocation de certificats est vide (aucun certificat révoqué), le FTD accepte le certificat comme valide et permet à l'utilisateur de s'authentifier.

La capture FTD suivante affiche la transaction HTTP entre le FTD et le CDP (serveur AC dans ce cas) afin de récupérer la liste de révocation de certificats.

Scénario 2. Le certificat est révoqué et l'authentification échoue

Un certificat d'identité est révoqué sur le serveur AC et enregistré dans le fichier de base de données CRL. Cependant, la liste de révocation de certificats mise à jour n'est pas disponible pour le FTD tant que la liste de révocation de certificats actuelle n'expire pas (configurée pour être valide pendant deux heures).

Lors d'une nouvelle tentative de connexion après la confirmation de l'expiration de la liste de révocation de certificats, l'inspection de certificat est généralement identique au scénario précédent. La nouvelle liste de révocation de certificats est demandée une fois que le FTD a confirmé l'absence de liste de révocation de certificats dans le cache. À la réception de la nouvelle liste de révocation de certificats, le FTD vérifie si le numéro de série du certificat d’identité fait partie de la liste. Le numéro de série est marqué comme révoqué et le FTD continue à refuser l'accès à l'utilisateur.
