What is Federated Monitoring?
A wise man once told me that there is a big difference between reachability and availability. Ever since I have been fascinated by the challenges that we face with net-centric information sharing and service dependencies which cross all forms of organizational, network, and even classification boundary. The reality here is that with net-centric approaches and the need to re-use services, we will have massive dependencies on services outside of our control.
The Federal Government has emphasized and even mandated in some cases the use of XML, Web Services, and SOA concepts and standards to align IT assets with business processes to employ the concept of netcentricity. Simply put the concept of netcentricity makes the right information available at the right time to the right people.
By exposing applications as reusable and dynamically composable services, new business processes can be defined on-demand to allow for business agility. This is especially important as Government organizations are constantly defining and building solutions for an evolving set of requirements many of which are based on a near term objectives to offer a set of capabilities to the war-fighter or analyst supporting an immediate threat.
The reality here is that these services will be stood up and offered throughout the government enterprise and will cross organizational, network, and potentially even classification boundaries. These newly formed IT Communities of Interest (CoI) will require a shared knowledge of their individual and collective purpose, mission objectives, service level agreements, security postures, and availability and reachability characteristics.
Existing monitoring approaches and products are based on the perspective of internal monitoring and portraying network, application, and service visibility. Within the DoD and IC the definition of enterprise is often not clear, and visibility and monitoring is segmented based on project, department, organization, branch of service, etc.. In Government, we are integrating our services across these different mini-enterprises and are lacking in an ability to monitor services in a federated fashion. Since netcentricity is all about services, I assert that we don't care that much about the health and availability of a server or an application, unless it impacts the service that we are using, and therefore my focus is on Federated Service Monitoring.
Federated service monitoring portrays the service availability information as it relates to usage of the service external to the enterprise. Availability in this case is measured not only by the internal services status, but additionally by aspects of the service provider's network. This end-to-end reachability information must be portrayed outside the enterprise in a secure fashion and made available to those wishing to use the service. With federated monitoring service implementers can extend their internal monitoring external to the organization to allow for business partners to accurately measure services availability, reachability, and performance in an ongoing fashion.
The Department of Defense (DoD) and Intelligence Community (IC) has developed the Joint DoD/IC Enterprise Service Monitoring (JESM) Specification, which in time will be used across the govenrment as a way of doing secure federated monitoring. The JESM specification is based on a subset of WSDM relevant to DoD/IC use-cases and WS-Eventing.
Layer 7 Technologies (www.layer7tech.com) SecureSpan and CloudSpan line of products are fully supportive of the Joint DoD/IC ESM specification. For every service within Layer 7, JESM monitoring can be enabled for external consumption of service metrics. The JESM Service supports request/response or publish/subscribe and for each JESM enabled service (Mission App A-C, etc.) and policy can be enforced to ensure access-control, confidentiality, integrity, and audit of JESM data. For example, Mission Application A metrics can be made available, but access limited by the attributes of the authenticated subject whom is requesting them.
In my time working with government, I have seen numberous occations where a service went down and noone knew for several days, all while they believed the data coming from the service was still available.
Mission IT visibility (past, current, and future) and operational flexibility (in the face of attack or even power failure) is critical. Federated monitoring isn't a silver bullet, however I believe it will be helpful in allowing for communities of interest to come together quickly, integrate their IT, while providing visibility and react-ability in the case of failure.
Security testing is must. Everybody wants security at every level of his working. as explained above failures are happened but if we test time to time then it will improve. So it depend on us how much we are serious about this.ReplyDelete
