2.2 RADIUS packet structure
RADIUS is the protocol at the application layer. In the transport layer, its packets are encapsulated in UDP packets and then encapsulated into the IP packet. Port 1812 is used for RADIUS Authentication, and port 1813 is used for billing.

Validating modelsThe validation model is used to verify that the cached response data is kept up-to-date.In this case, when the cached data is going to be the response of the client request, it first checks the source server or the intermediate cache with the latest data to see if the data it caches is still up to date. This is where the authenticator is going to be used .ValidatorThere are two types of validator

When we use security-related data for interaction, such as user account authentication (LOGIN) and authorization management, Shiro will find relevant data from one or more configured Realms.From this perspective, Realms is actually a DAO: encapsulates the details of the connection to the data source and enables Shiro to easily read the relevant data. When we configure Shiro, there must be at least one Realms. SecurityManager can be configured by multiple Realms, but at least one Realms is

However, for small and medium enterprises, the cost of using commercial identity authentication solutions such as RSA is high. The lack of IT budget often limits enterprises' choice of two-factor solutions.
