Classification: CPC H  G | IPC G  H

Claim 0:
1. A system, comprising:
a processor configured to:
receive an input value;
receive an update that includes updated versions of a bitmap table, a default state table, and a rule table from a cloud security service, wherein the updated versions of the bitmap table, the default state table, and the rule table are stored;
determine a next state based on a lookup key by performing a lookup in the updated bitmap table using the lookup key to determine whether to obtain the next state from the updated default state table or the updated rule table, wherein the lookup key comprises a current state and the input value, and wherein the determining of the next state comprises to:
determine whether the updated bitmap table returns a default state or a valid state using the lookup key, the default state corresponding to a most commonly occurring next-state pointer, the default state being different from the valid state; and
in response to a determination that the updated bitmap table returns the default state, determine that the next state is to be obtained from the updated default state table; and

determine the next state based on the lookup key, comprising to:
in response to a determination that the next state is to be obtained from the updated default state table, obtain the next state from the updated default state table based on the lookup key; and

a memory coupled to the processor and configured to provide the processor with instructions.
