5.4.2 Certificate Management
Overriding a Device Configuration
A certificate links identity information with a public key enclosed in the certificate.
A certificate authority (CA) is a network authority that issues and manages security credentials and public keys for message
encryption. The CA signs all digital certificates it issues with its own private key. The corresponding public key is contained
within the certificate and is called a CA certificate. A browser must contain this CA certificate in its Trusted Root Library so it
can trust certificates signed by the CA's private key.
Depending on the public key infrastructure, the digital certificate includes the owner's public key, the certificate expiration
date, the owner's name and other public key owner information.
Each certificate is digitally signed by a trustpoint. The trustpoint signing the certificate can be a certificate authority,
corporation or individual. A trustpoint represents a CA/identity pair containing the identity of the CA, CA-specific configuration
parameters, and an association with an enrolled identity certificate.
SSH keys are a pair of cryptographic keys used to authenticate users instead of, or in addition to, a username/password. One
key is private and the other is public key. Secure Shell (SSH) public key authentication can be used by a client to access
resources, if properly configured. A RSA key pair must be generated on the client. The public portion of the key pair resides
with the licensed device, while the private portion remains on the client.
The certificate configuration used by an access point managed device can be changed (overridden) as changes in security
credentials require modification in the management of the device.
