Applying blocking measures progressively to malicious network traffic
A method of progressive response for invoking and suspending blocking measures that defend against network anomalies such as malicious network traffic so that false positives and false negatives are minimized. When an anomaly is detected, the detector notifies protective equipment such as a firewall or a router to invoke a blocking measure.

If the anomaly is no longer evident, the method returns to the state of readiness. Otherwise, a loop is executed to re-apply the blocking measure for a specified duration, then suspend the blocking measure and test again for the anomaly. If the anomaly is detected, the blocking measure is re-applied, and its duration is adapted. If the anomaly is no longer detected, the method returns to the state of readiness.

System and method for reliably replicating data
Described is a system and method for replicating each of a set of resources to a subject computer in a replica set prior to making use of a resource in the set of resources. The set of resources includes resources that are dependent upon each other for a proper functioning of the group. A manifest file that identifies each resource in a group of interrelated resources is used. The manifest file is generated at one computer in the replica set (typically the computer at which a modification to one of the interrelated resources occurred). When the modification occurs to one of the set of resources, the manifest file is transmitted (e.g., itself replicated) to each computer in the replica set. The manifest file includes an indicator that identifies the manifest file as a special file. When received at another computer in the replica set, a service evaluates the manifest file to identify whether the appropriate versions of the identified resources exist at the receiving computer. If not, the service at that computer awaits the receipt of each resource. The wait period may include delaying the execution of an application associated with (or even included within) the manifest file from launching. Alternatively, the FRS could simply disallow access to one or more resources identified in the manifest file until all have arrived. When all have arrived, the FRS releases control of the identified resources, which may then operate or be accessed in the ordinary manner.
