A memory system system includes a single in-line memory module which contains a memory device and a signal transmission line connected between the memory device and a connection terminal, and a dual in-line memory module which contains two memory devices and a signal transmission line connected between the two memory devices and a connection terminal. The present invention allows a conversion from a format of the IEEE 1394 to the VSB remodulator and also a conversion from a format of the VSB remodulator to the IEEE 1394. Thereafter, the engine retrieves a set of rules for accessing the resource, applies the rules to the security claims to determine whether to allow the request from the requestor, and if the request is to be allowed, provides the requestor access to the resource in accordance with the request and the rights of the requestor as determined based on the security claims.
