The Mounting Case for Cloud Access Brokers

Addressing the need for flexible control of access to off-premise applications

Unifying identity and access management has been a stretch goal for IT for nearly a decade. At first it was merely the need to have a single, authoritative source of corporate identity such that risks like orphaned or unauthorized accounts could be addressed within the enterprise.

But with a growing number of applications - business applications - being deployed "in the cloud", it's practically a foregone conclusion that organizations are going to need similar capabilities for those applications, as well.

It's not easy, there are myriad reasons why unifying identity and access control is a stretch goal and not something easily addressed by simply deploying a solution. Federation of identity and access control requires integration. It may require modification of applications. It may require architectural changes.

All of these are disruptive and, ultimately, costly. But the costs of not addressing the issue are likely higher.

Security a Rising Concern for Cloud-Based Application Usage

With access to these applications taking place from a variety of locations including smartphones (80 percent),tablets (71 percent) and non-company computers (80 percent) and with a large percentage of organizations (73 percent) needing to grant temporary access to cloud apps, respondents cited concerns around identity management, governance and complexity.

...

Nearly three-quarters (72 percent) of the respondents said they have the need to provide external users, such as consultants, with temporary access to the company’s cloud applications, while just under half (48 percent) of respondents said they are still not able to sign in to cloud applications with a single set of credentials. [emphasis mine]

There is a significant loss of control - in terms of governance - that's occurring, where the organization no longer has the means by which they can control who has access to applications, from what device or location, and when. That's the downside of cloud, of distributed systems that are not architected with security in mind.

Make no mistake, it's not just IT making a power grab for power's sake. This is a real, significant issue for the business side of the house, because it is their applications - and ultimately data - that is at risk by failing to properly address issues of access.

THE CASE FOR CLOUD ACCESS BROKERS

The least disruptive - and most efficient - means of addressing this disconnect is to insert into the data center architecture an access broker tier, a layer of dynamic access and identity management services designed to provide federation and unification of credentials across cloud and data center resources based on the organization's authoritative source of identity.

The advantages of such a tier are that they are less disruptive, it respects the authoritative source of identity and it is highly flexible. The same cloud access broker that provides authentication and authorization to internal resources can do so for cloud-based resources. The downside is integration with a growing variety of SaaS and custom cloud-deployed applications used by the enterprise. A standards-based way of integrating off-premise applications with a cloud access broker is needed, and we find such a standard in SAML 2.0, an increasingly popular means of integrating identity and access management services across the cloudosphere.

In addition to providing access control through such integration, a cloud access broker also provides the means for IT to address the issue of password security noted in "Security a Rising Concern for Cloud-Based Application Usage":

The survey indicated unsafe password management continues to be a challenge, with 43 percent of respondents admitting that employees manage passwords in spreadsheets or on sticky notes and 34 percent share passwords with their co-workers for applications like FedEx, Twitter, Staples and LinkedIn. Twenty percent of respondents said they experienced an employee still being able to log in after leaving the company.

By enabling federation and single-sign on capabilities, organizations can mitigate this problem by ensuring users have fewer passwords to recall and that they do not share them with off-premise applications like FedEx. Because IT controls the authoritative source of identity, it also governs policies for those credentials, such as password length, history, interval of change, and composition.

FEDERATION MEANS HEIGHTENED (AND ENFORCEABLE) SECURITY

Federation of identity and access management through a cloud access broker can alleviate the loss of control - and thus expanding security threats.

By maintaining the authoritative source of identity on-premise, organizations can enforce security policies regarding password strength and length while improving the overall experience for end-users by reducing the number of credentials they must manage to conduct daily business operations. Issues such as orphaned or rogue accounts having access to critical business applications and data can be more easily - and quickly - addressed, and by using a flexible cloud access broker capable of transitioning security protocols, device incompatibility becomes a non-issue.

As more and more organizations recognize the ramifications of unfettered use of cloud services it is inevitable that cloud access brokers will become a critical component in the data center.

Most DevOps journeys involve several phases of maturity. Research shows that the inflection point where organizations begin to see maximum value is when they implement tight integration deploying their code to their infrastructure. Success at this level is the last barrier to at-will deployment. Storage, for instance, is more capable than where we read and write data. In his session at @DevOpsSummit at 20th Cloud Expo, Josh Atwell, a Developer Advocate for NetApp, will discuss the role and value extensible storage infrastructure has in accelerating software development activities, improve code quality, reveal multiple deployment options through automated testing, and support continuous integration efforts. All this will be described using tools common in DevOps organizations.
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the benefits of the cloud without losing performance as containers become the new paradigm.
Security, data privacy, reliability and regulatory compliance are critical factors when evaluating whether to move business applications from in-house client hosted environments to a cloud platform. In her session at 18th Cloud Expo, Vandana Viswanathan, Associate Director at Cognizant, In this session, will provide an orientation to the five stages required to implement a cloud hosted solution validation strategy.
In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise.
The current age of digital transformation means that IT organizations must adapt their toolset to cover all digital experiences, beyond just the end users’. Today’s businesses can no longer focus solely on the digital interactions they manage with employees or customers; they must now contend with non-traditional factors. Whether it's the power of brand to make or break a company, the need to monitor across all locations 24/7, or the ability to proactively resolve issues, companies must adapt to the new world.
