So, Just What Is REACT? And How Does It Change Security Strategies?
Examining the advantages of cloud-based unified security

Last month, I published an article about a new unified security platform called REACT (Realtime Event & Access Correlation Technology). All in all, it received some very positive notices, but also raised some questions as to what exactly the platform is, and why it should matter.
Simply put, REACT is an approach whereby an organization leverages the capabilities of several security solutions into one central correlated repository of security intelligence. For instance, key information from an Access Management tool (such as SaaS SSO logins or views of/modifications on/additions to protected data) can be shared, processed and analyzed through a SIEM correlation engine. When this is done in real time, not only do you expand the centralized visibility, but more importantly any suspicious activity is immediately identified and alerted. When these systems are running in parallel, but not unified, it might be days or weeks before these anomalous instances are discovered and remedied.
REACT incorporates four elements: SIEM, Access Management, Identity Management and Log Management. Each, independently, addresses certain security and/or compliance functions. As a deployment of centralized and unified security, they enhance the enterprise’s ability to perform, improve the granular visibility across independent silos and provide a true field of play in which to… yes…react! But the key is this monitoring must be done in real time to gain the advantages of proactive readiness and agile and accurate response.
Think of REACT like an apple pie. You might have apples, dough crust, butter and spices. Each can be used on their own. However, when using each of the ingredients together, you create a tasty result that is more than the sum of its parts. As a platform, REACT is similar. Your organization may already have Identity Management or SSO, but if it isn’t “baked” together with forensic analytics like SIEM and/or Log management, you only get a portion of the information and a slice of the capability.
Why does that matter? Let’s break it down into 3 key business advantages:
1. Creating 360o Visibility -In the current complex, multi-networked and interlaced business environment, the ability to know who is doing what, when and where to any part of the monitored IT landscape has moved beyond the “nice-to-have” strategy. Anything less is short sighted, and honestly, dangerous. It seems every few weeks, we hear about a large organization suffering some kind of breach. It could be internal sabotage, user carelessness, or hackers, but either way, sensitive data has been put at risk. By employing the unique advantage of multi-silo correlation and information distillation, the ability to expand visibility manifests as a huge return on investment through prevented breaches, supported work practices and easier compliance.
This enhanced visibility goes a long way toward internal proactive defense planning: who is logging in (or failing), modifying records, accessing data from any affiliated app across the entire extended network. When you have the right level of visibility, you can make better decisions faster...especially when factoring Big Data and BYOD.
2. Improved compliance - One of the top concerns for enterprises are compliance requirements. Hundreds of man-hours and other resources must be deployed per month just to provide the reports auditors require. When approaching security from a non-unified approach, IT needs to look at machine data and logs from many different servers from many different sectors of the network. It’s a Herculean task given the best of circumstances. With multiple audits from multiple agencies, it takes an inordinate amount of time away from other core business needs. Yet when unifying and centralizing (and automating) the data required by audits, compliance becomes less of a burden. The automations across the enterprise now deliver the prescribed data in the right format, fully completed by the imposed deadlines
And also consider, requirements from agencies like HIPAA, PCI, FFIEC, CIP GLBA, SOX are not going to lessen. If history teaches us anything, the demands of such organizations are only going to increase as the usage cases of your online assets continue to diversify and evolve.
3. More capability for less cost - In many circumstances, asking an organization to make investments in all sorts of security solutions is cost prohibitive. Not to mention all the other time, personnel and computing resources needed to properly deploy the initiative. By leveraging the security functionality from the cloud, companies gain additional and immediate solution bandwidth along with expanded capabilities. As a unified security deployment from the cloud, the cost-to-function ratio dramatically drops. Colloquially speaking, you get more bang for the buck. But because the solutions are managed from the cloud it is not an apples-to-apples comparison. REACT can work as an on-premises platform, but through multi-tenancy, centralization and other economies of scale, cloud-based security users get best of breed solutions for pennies against the on premises dollar. In short the cloud provides a unique advantage in functionality, affordability and control for any sized company—not just the big boys.
So to recap… REACT is not a collection of individual solutions and functions, but an interpolation of all the data across the enterprise to gain a truly holistic security vantage point. AND REACT matters because you can see more, see it faster, manage it cheaper and protect a greater swath of your enterprise. It’s a simple calculation-especially from the cloud.

Did you know that ninety percent of the data in the world has been created in the last two years? Every day, we create 2.5 quintillion (or 2.518) bytes of data, according to IBM. As corporations across all industries globally are struggling with how to retain, aggregate and analyze this mounting volume of what the industry refers to as Big Data, it also provides a unique opportunity for innovative startups that recognize the business prospects Big Data presents. Big Data is not just unlocking new information but new sources of economic and business value. Interactivity is driving Big Data, with people and machines both consuming and creating it. Digital companies focused on becoming good at aggregating and analyzing the data created by the end users of their product, who then provide their customers with solid insights taken from that data are at a distinct competitive advantage over others in the marketplace.
Industry-specific clouds are those PaaS, IaaS, and PaaS services that are tailored for a specific vertical, such as transportation, retail, finance, and health care. IDC sees a $65 billion market in these industry solutions for 2013, rising to $100 billion in 2016. The value of industry-specific clouds is that businesses within a vertical can connect to applications, processes, and databases that are pre-defined for that vertical within a public or private cloud. They can extend processes and databases into the business domain, versus defining the data and processes within a generic cloud-based platform. So, are industry specific clouds right for your business? What options are out there? How do you figure out the ROI?

Cloud computing is becoming one of the next industry buzz words. It joins the ranks of terms including: grid computing, utility computing, virtualization, clustering, etc. Cloud computing overlaps some of the concepts of distributed, grid and utility computing, however it does have its own meaning if contextually used correctly. The conceptual overlap is partly due to technology changes, usages and implementations over the years. Trends in usage of the terms from Google searches shows Cloud Computing is a relatively new term introduced in the past year. There has also been a decline in general interest of Grid, Utility and Distributed computing. Likely they will be around in usage for quit a while to come. But Cloud computing has become the new buzz word driven largely by marketing and service offerings from big corporate players like Google, IBM and Amazon.

One of the most compelling promises of the cloud is that you can pull out a credit card and be working in minutes. No purchase orders to fill out, no equipment to wait for on the loading dock. Just instant access to the resources you need, when you need them. But accessibility comes at a price, and an unintentional consequence may be that you create yet another orphaned identity silo. Enterprise IT has spent years consolidating its mishmash of directories, only to discover that cloud now threatens to turn back their hard-won victories. In his session at the 12th International Cloud Expo, Scott Morrison, CTO and Chief Architect at Layer 7 Technologies, will look at strategies to incorporate identity into cloud applications. Enterprise identity or social login can both be a part of your go-to-cloud strategy, but you must plan for this upfront, rather than try to retrofit identity and access control at a later date.
