Coordinating Security Information

What happens when an agency finds a better point solution than one currently in place?

A recent article in Government Computer News raised the topic of FISMA reporting, specifically describing the "pessimism" of many USG agencies over meeting the September 2012 deadline for "using continuous monitoring to meet Federal Information Security Management Act reporting requirements." The article cites a survey of over 200 government IT professionals, conducted by RedSeal Networks, in which 55% of respondents felt they won't be ready, or don't know if they will be ready, by the deadline. One can certainly debate the significance of the number of agencies expressing concern over meeting the deadline, and the reasons given would likely drag the conversation to arguing over the validity of a deadline set by government for something that is far more complex than "flipping a switch." But set that aside for the moment.

More interesting is the fact that, when you look at the responses by the role of the respondents, "53 percent of security managers, administrators and auditors expected to meet the Sept. 30 deadline, while only 28 percent of CIOs and chief information security officers expected to." Mike Lloyd, RedSeal's CTO, said "This is an interesting finding, not what a cynic might expect." That cynic would expect the typical (over-)confidence of an executive, the one telling folks "no problem, we're right on track" while the IT managers, the ones actually tasked with the design, deployment and operation of relevant systems, the feverish scramble to find the right tools, the right people, and the right data to meet the reporting requirement.

In fact, the opposite is the case. The IT managers believe they have the right point solutions to do the monitoring, analyze the data, and process the relevant compliance reports. They aren't worried about trying to figure out how they're going to perform the continuous monitoring, primarily because today's IT vendors are creating products that provide the capabilities to meet these requirements. So why don't these CIOs and CISOs share the confidence of their IT staff?

The answer is both simple ... and not so simple. In discussing this survey and resulting article, the editors at SANS described the lack of C-level confidence this way (emphasis added): "Agencies need to find ways to bring together information from various systems to provide the necessary set of data." Bring information together? That's easy, just get a bunch of good developers to build custom integration points between all these systems that the IT managers feel really good about (rightly so), and then the data will flow! Sounds great...until you look a little closer at what this entails: a group of good developers is expensive, not to mention hard to find. Assuming you can find all these good developers (and afford to pay them), can they knock this effort out in, say, 6 months? 9 months? Factor in the unique and often proprietary formats and data structures of these various solutions, and now what, 12 months? Remember that September deadline?

What happens when the agency finds a better point solution than one currently in place? Bring back those good, expensive developers (or retain them) to build new integration points between the existing solutions and this new one? Not so simple anymore, is it?

This approach is not timely, cost-effective, or scalable. A better approach is to build a foundation that allows these best-of-breed point solutions to share data in a common format, providing each solution with the ability to use only that data that is relevant to it.

Over the last four years, the Trusted Computing Group (trustedcomputinggroup.org) has developed and published a set of open specifications called IF-MAP (or "Interface to Metadata Access Points"). IF-MAP is a protocol specifically designed to allow disparate systems from different vendors to share information. The IF-MAP open standard makes it possible for any authorized device or system to publish information to an IF-MAP server, to search that server for relevant information, and to subscribe to any updates to that information. This "sharing" is done in a standardized way, eliminating the need for costly custom integration points between these disparate systems. Through the use of IF-MAP, agencies would have the ability to enable data and information sharing between systems in an automated and continuous manner.

Share data without allowing unauthorized access among logs, records/databases, firewalls, provisioning systems, switches, and more.

Track devices and their owners on the network.

Track/monitor network traffic.

Control the activity/access of devices operating inappropriately.

Manage/Tie legacy systems into global enterprise (i.e., SCADA).

Validate endpoints and allow access (Standard managed endpoint security).

Share security data among devices and have those security devices act based on the collective available data.

And the best part - many government agencies already have solutions in place that support IF-MAP. Vendors including Lumeta, Juniper, Enterasys, and Infoblox, just to name a few, have products supporting IF-MAP. Numerous government agencies and system integrators have labs dedicated to using IF-MAP and similar open standard specifications to develop solutions to the biggest cyber-security challenges out there - such as real-time configuration management databases; the integration of physical and network security; and policy-based remote access - all using IF-MAP and COTS products.

IF-MAP alone won't necessarily help those agencies meet the September deadline, but one thing is certain - not using open standards and specifications such as IF-MAP will make the effort more costly, more time-consuming, and less flexible. If you can show me a government agency that has extra money and extra time, I'd love to see it.

You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He ended the session with some interesting case study examples.
One of the ways to increase scalability of services – and applications – is to go “stateless.” The reasons for this are many, but in general by eliminating the mapping between a single client and a single app or service instance you eliminate the need for resources to manage state in the app (overhead) and improve the distributability (I can make up words if I want) of requests across a pool of instances. The latter occurs because sessions don’t need to hang out and consume resources that could ...
Microservices has the potential of significantly impacting the way in which developers create applications. It's possible to create applications using microservices faster and more efficiently than other technologies that are currently available. The problem is that many people are suspicious of microservices because of all the technology claims to do. In addition, anytime you start moving things around in an organization, it means changing the status quo and people dislike change. Even so, micr...

Digital Transformation is the ultimate goal of cloud computing and related initiatives. The phrase is certainly not a precise one, and as subject to hand-waving and distortion as any high-falutin' terminology in the world of information technology. Yet it is an excellent choice of words to describe what enterprise IT—and by extension, organizations in general—should be working to achieve. Digital Transformation means: handling all the data types being found and created in the organizat...
JavaScript is primarily a client-based dynamic scripting language most commonly used within web browsers as client-side scripts to interact with the user, browser, and communicate asynchronously to servers. If you have been part of any web-based development, odds are you have worked with JavaScript in one form or another. In this article, I'll focus on the aspects of JavaScript that are relevant within the Node.js environment.
Approved this February by the Internet Engineering Task Force (IETF), HTTP/2 is the first major update to HTTP since 1999, when HTTP/1.1 was standardized. Designed with performance in mind, one of the biggest goals of HTTP/2 implementation is to decrease latency while maintaining a high-level compatibility with HTTP/1.1. Though not all testing activities will be impacted by the new protocol, it's important for testers to be aware of any changes moving forward.
This week, I joined SOASTA as Senior Vice President of Performance Analytics. Given my background in cloud computing and distributed systems operations — you may have read my blogs on CNET or GigaOm — this may surprise you, but I want to explain why this is the perfect time to take on this opportunity with this team. In fact, that’s probably the best way to break this down. To explain why I’d leave the world of infrastructure and code for the world of data and analytics, let’s explore the timing...

Auto-scaling environments, micro-service architectures and globally-distributed teams are just three common examples of why organizations today need automation and interoperability more than ever. But is interoperability something we simply start doing, or does it require a reexamination of our processes? And can we really improve our processes without first making interoperability a requirement for how we choose our tools?
Cloud Migration Management (CMM) refers to the best practices for planning and managing migration of IT systems from a legacy platform to a Cloud Provider through a combination professional services consulting and software tools. A Cloud migration project can be a relatively simple exercise, where applications are migrated ‘as is’, to gain benefits such as elastic capacity and utility pricing, but without making any changes to the application architecture, software development methods or busine...
The Internet of Things. Cloud. Big Data. Real-Time Analytics. To those who do not quite understand what these phrases mean (and let’s be honest, that’s likely to be a large portion of the world), words like “IoT” and “Big Data” are just buzzwords. The truth is, the Internet of Things encompasses much more than jargon and predictions of connected devices. According to Parker Trewin, Senior Director of Content and Communications of Aria Systems, “IoT is big news because it ups the ante: Reach out ...
At DevOps Summit NY there’s been a whole lot of talk about not just DevOps, but containers, IoT, and microservices.
