With two-factor security, a user requires a password and another form of identity, such as a token, to be authenticated. Federated security relies on partnerships to allow a user authenticated on one system to be authenticated on a partner's system.
RSA said the new product would enable enterprises to securely exchange digital identities with business partners and could be used in a situation where a user authenticated on a system using the two-factor method can access a second system via the federated model.
By combining two-factor and federated security, RSA said users could carry a single token that would be recognised by multiple RSA Ace/Server software installations that are linked with RSA Federated Identity Manager.
