A database access control system is augmented to provide additional functionality to enable an external security device (e.g., an EDSM) to fully and accurately assess a database query against one or more security policies even when the EDSM is overloaded. To this end, a pair of channels is established between the ISA and the ESM, wherein the channel pair includes a first channel that is expected to have relatively low packet rate, and a second channel that is expected to have a relatively high packet rate. Packets representing initial session information (i.e., user information sent at the beginning of a user session) are directed to the first channel, whereas packets received following session establishment are directed to the second channel, because the latter are likely to be present during a potential overload scenario.
