The Importance of Context to Mobility

Mobility introduces a few new entities to the equation, all of which have to be taken into account for ideal contextual decision

My grandfather has a bumper sticker on his pickup truck that says “He who dies with the most toys, wins.” Since my world revolves more around API Management than collecting die-cast models of John Deere tractors, I have my own version of the saying – “He who has the most context wins.” Context has always been an important part of managing data or applications, but the proliferation of enterprise B2E (business-to-employee) and B2C (business-to-consumer) mobile apps has significantly increased the need for context-based policy.

Mobile ContextThe Layer 7 family of API Gateways has always been good at context. Not only does a Gateway have access to the full request and response content, it can also access header content (from a wide variety of protocols) and transaction metadata (latency, source information etc.) Then it adds in user credentials and attributes retrieved from the request and backend identity management systems. These inform decisions around access control but also around traffic routing, prioritization, rate limiting, quota fulfillment etc.

However, mobility introduces a few new entities to the equation, all of which have to be taken into account for ideal contextual decision-making. The first is familiar: users; but mobile users might have additional attributes that come into play. Phone number and email become more important, since they provide other connection points accessible to the user on the same device (smartphone, tablet etc.) The inclusion of social login – available in the 2.1 release of our Mobile Access Gateway – provides social graph information that might also have relevance when deciding how a user request should be processed.

The second entity providing contextual attributes is the app itself. An app ID or API key can tie an application back to the developer who created it. Signer information, permissions and other internal details can give context around existing app security. The Mobile Access Gateway can collect some of this information using our Mobile SDK and more data can be gathered via integration with CA (or third-party) MAM and MDM products.

The third important entity is the device itself. Not only can APIs be tailored to return data structures specific to a screen size or even a specific device type but behavior can also be tracked to a single device ID to analyze the risk involved. There might be more risk delivering sensitive data to a family iPad than there would be on a personal smartphone – or to a phone in an airport rather than a laptop in the office. This level of risk (and the associated response) increases dramatically when interacting with an unlocked device rather than one locked down by corporate security policies.

In my new role across the CA Securecenter product line, I’ve focused quite a bit on the integration of Layer 7 with other CA products. The result has been a flood of new contextual information with which to make richer decisions. Gathering risk profiles from CA RiskMinder or data categorization from CA DataMinder provides an even stronger understanding of who is trying to access what, from where. And the decision made from this context doesn’t necessarily have to result in a thumbs-up or thumbs-down; with CA AuthMinder, suspicious requests can simply require an additional level of authentication.

Every industry has its own variables, vulnerabilities and potential optimizations. Our goal is to give customers the right context with which to make the best decisions for their specific use cases. Our rich interface management capabilities and strong integrations with other proprietary and standards-based mobile technologies give us the best palette of access control and policy options in the API Management industry. In a world where context is king, we’re continually fighting for that crown.

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
When applications are hosted on servers, they produce immense quantities of logging data. Quality engineers should verify that apps are producing log data that is existent, correct, consumable, and complete. Otherwise, apps in production are not easily monitored, have issues that are difficult to detect, and cannot be corrected quickly. Tom Chavez presents the four steps that quality engineers should include in every test plan for apps that produce log output or other machine data. Learn the ste...

Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
When building large, cloud-based applications that operate at a high scale, it's important to maintain a high availability and resilience to failures. In order to do that, you must be tolerant of failures, even in light of failures in other areas of your application. "Fly two mistakes high" is an old adage in the radio control airplane hobby. It means, fly high enough so that if you make a mistake, you can continue flying with room to still make mistakes. In his session at 18th Cloud Expo, Le...
