A computer readable storage medium with executable instructions specifies the execution of a state machine operating across a set of computing nodes in a distributed computing system. The executable instructions execute a set of operators, where the execution of each operator is under the control of a state machine that periodically invokes pause control states to pause the execution of an operator in response to a violation of a service level agreement specifying an operating condition threshold within the distributed computing system. Partitions of input data are formed that are worked on independently within the distributed computing system. A set of data batches associated with the input data is processed. Data partition control states to process the partitions associated with the set of data batches are specified. Key control states to process a set of keys associated with a data partition of the partitions are defined.

State machine controlled dynamic distributed computing

A computer readable storage medium includes executable instructions to define an interface to a multi-dimensional cube divided into partitions distributed across nodes supporting a shared nothing multi-dimensional distributed database. The interface includes a metadata module characterizing access paths to data within the multi-dimensional cube and an access path module to convert a data request into an access path protocol to retrieve data from the multi-dimensional cube to satisfy the data request.

Apparatus and method for accessing materialized and non-materialized values in a shared nothing system

A computer readable storage medium includes executable instructions to receive a request for data from a multi-dimensional cube divided into partitions distributed across nodes supporting a shared nothing distributed multi-dimensional database. The request is transformed into physical access layer operators in a tree structure. The tree structure is reduced into an index scan operator.

Apparatus and method for processing multi-dimensional queries in a shared nothing system through tree reduction

A distributed computing system includes a memory storing execution state collected prior to an operator pause state. A controller modifies, during the operator pause state, characteristics of the distributed computing system. The controller invokes execution of the operator after the pause state such that the operator accesses the execution state to complete an operation.

System for pause and play dynamic distributed computing

A method of detecting intrusions on a computer includes the step of identifying an internet protocol field range describing fields within internet protocol packets received by a computer. A connectivity range is also established which describes a distribution of network traffic received by the computer. An internet protocol field threshold and a connectivity threshold are then determined from the internet protocol field range and connectivity range, respectively. During the operation of the computer, values are calculated for the internet protocol field range and connectivity range. These values are compared to the internet protocol metric threshold and connectivity metric threshold so as to identify an intrusion on the computer.

Method and apparatus for detecting intrusions on a computer system

A method of forming a virtual intrusion detection system includes the step of positioning a set of sensors in a network environment, each sensor supporting multiple logical traffic paths. The method also includes the step of providing a set of sensor management systems corresponding to the set of sensors. This set of sensor management systems enforces a set of virtual intrusion detection systems, wherein each virtual intrusion detection system corresponds to a predetermined logical traffic path through the set of sensors, each virtual detection system providing sensor traffic information solely to authorized parties.

Virtual intrusion detection system and method of using same

An intrusion signature describing an attack is stored on a computer. Once a plurality of internet protocol packets is received, the plurality of internet protocol packets collectively containing an information sequence within a series of states, it is rearranged so as to place the information sequence in order. Each state of the series of states is then successively examined so as to correlate the information sequence to the intrusion signature.

Protocol-parsing state machine and method of using same

A method of provisioning a computer against computer attacks includes constructing a hierarchy characterizing different computer attacks and counter measures, and traversing this hierarchy to identify computer attacks and countermeasures relevant to a target platform. Detection and protection measures are collected in response to this traversing. These detection and protection measures are then downloaded to a security sensor associated with the target platform.
