Map Service allows a sophisticated mechanism to propagate business relevance data throughout the system. This facility aids scalability and provides an extensibility advantage by enabling intelligent data transfer between different nodes of the distributed system.
Map Service is a data propagation facility that gives the ability to cross-reference Vulnerability Scanner data with Intrusion Detection System signatures and more (for example, asset data, business-relevant data). This allows immediate notification when an attack is attempting to exploit a vulnerable system. Three separate components provide this functionality:
Collection of real time events from an intrusion detection source;
Comparing those signatures to the latest vulnerability scans; and
Cross referencing an attack feed through Sentinel Advisor (an optional product module, which cross-references between real-time IDS attack signatures and the user's vulnerability scanner data).
Map Service dynamically propagates information throughput the system without impacting system load on the system. When important data sets (that is, "maps" such as asset information or patch update information) are updated in the system, the Map Service propagates the updates across the system, which can often get to be hundreds of megabytes in size.
iSCALE's Map Service algorithms handle large referential data sets across a production system processing large real-time data volumes. These algorithms are "update-aware" and selectively push only the changes or "delta data sets" from the repository to the edge or system perimeter.
