Title

The RUCKUS ICX device must be configured to include only approved trust anchors in trust stores or certificate stores managed by the organization. (Cat II impact)

Discussion

Public key infrastructure (PKI) certificates are certificates with visibility external to organizational systems and certificates related to the internal operations of systems, such as application-specific time services. In cryptographic systems with a hierarchical structure, a trust anchor is an authoritative source (i.e., a certificate authority) for which trust is assumed and not derived. A root certificate for a PKI system is an example of a trust anchor. A trust store or certificate store maintains a list of trusted root certificates.

Fix Text

To allow a client to communicate with another RUCKUS ICX device using an SSL connection, a set of digital certificates and RSA public-private key pairs must be configured on the device. A digital certificate is used to identify the connecting client to the server. The certificate contains information about the issuing Certificate Authority as well as a public key. Digital certificates and private keys can be imported from a server. Copy the certificates from the server to flash memory and save the configuration.
