Note, that other security devices like the ASA also support wildcard certificates. There can be a number of benefits using wildcard certificates, but there are also a number of security considerations related to wildcard certificates including:ġ) Loss of auditability and non-repudiationģ) Not as common or as well understood by adminsĪlthough considered less secure than assigning a unique server certificate per ISE node, cost and other operational factors often outweigh the security risk and necessitate the need to offer this as an option to our customers in their ISE deployments. Less prompting and more seamless connectivity will translate into happier users and increased productivity. Ultimately, wildcard certificates result in an improved user experience. With wildcard certificates, a single server certificate can be trusted rather than individual certificates from each PSN.

For example, Microsoft Windows supplicant with PEAP-MSCHAPv2 and server cert trust enabled often requires specification of each server certificate to trust, or user may be prompted to trust each PSN certificate when client connects using a different PSN. Using a wildcard certificate, the certificate will be the same across all PSNs, so user will only need to accept certificate once and successive authentications to different PSNs should proceed without error or prompting.Ĥ) Simplified supplicant configuration. When an iOS client first communicates to a PSN it will not explicitly trust the PSN certificate, even though a trusted Certificate Authority has signed the certificate. Wildcard certificates address issues as seen with Apple iOS devices where client stores trusted certificates within the profile, and does not follow the iOS Keychain where the signing root is trusted. In addition to significant cost savings, certificate administration is also simplified through “create once, apply to many”.ģ) Reduced authentication errors.

Wildcard certificates allow all Policy Service Node (PSN) EAP and web services to share the same certificate. Wildcard certificates may be used on all nodes of the ISE Deployment (also referred to as the “ISE Cube”).Ģ) Operational efficiency. Certificates signed by a 3rd-part Certificate Authority can be costly, especially as the number of servers increase. Some examples of benefits of wildcard certificate usage are:ġ) Cost savings.

Ultimately, those who choose to use them, do so to ensure the end-user experience is as seamless as possible, especially given the vast difference and variety of endpoints. There are a number of reasons to implement wildcard certificates with an ISE deployment. Aaron Wolandįigure 3 - PEAP Example Why use Wildcard Certificates? Figure 3 describes an example using PEAP. In a Secure Access deployment, the client is a supplicant, and the server is an ISE Policy Services node. The client’s credentials are not sent to the server until after this tunnel is established, thereby ensuring a secure exchange. If the client trusts the certificate, the TLS tunnel is formed. Much like going to an HTTPS web site, the client establishes the connection to the server, which presents its certificate to the client. With tunneled EAP methods such as PEAP and FAST, Transport Layer Security (TLS) is used to secure the credential exchange. Client Provisioning Portal (CPP) & Native Supplicant Provisioning (NSP)įigure 2 - Admin Portal Example EAP Communication:Ĭertificates are used with nearly every possible EAP method.Centralized Web Authentication (CWA) Portal.Figure 2 describes the TLS encrypted process when communicating to the Admin portal. HTTPS communication using the ISE certificate:Įvery web portal with ISE version 1.1.0 and newer is secured using HTTPS (TLS encrypted HTTP communication). The certificate is used for all HTTPS communication as well as the Extensible Authentication Protocol (EAP) communication. The certificates are used to identify the Identity Services Engine (ISE) to an endpoint as well as to secure the communication between that endpoint and the ISE node. Where are Certificates Used with ISE?Ĭertificates are employed often in a network implementing Secure Access. Wildcard certificates secure communications in the same manner as a regular certificate, and requests are processed using the same validation methods.
