Mapping Certificates to IPsec or SSL VPN Connection Profiles
When the adaptive security appliance receives an IPsec connection request with client certificate
authentication, it assigns a connection profile to the connection according to policies you configure. That
policy can be to use rules you configure, use the certificate OU field, use the IKE identity (i.e. hostname,
IP address, key ID), the peer IP address, or a default connection profile. For SSL connections, the
adaptive security appliance only uses the rules you configure.
For IPsec or SSL connections using rules, the adaptive security appliance evaluates the attributes of the
certificate against the rules until it finds a match. When it finds a match, it assigns the connection profile
associated with the matched rule to the connection. If it fails to find a match, it assigns the default
connection profile (DefaultRAGroup for IPsec and DefaultWEBVPNGroup for SSL VPN) to the
connection and lets the user choose the connection profile from a drop-down menu displayed on the
portal page (if it is enabled). The outcome of the connection attempt once in this connection profile
depends on whether or not the certificate is valid and the authentication settings of the connection
profile.
A certificate group matching policy defines the method to use for identifying the permission groups of
certificate users. You can use any or all of these methods.
