Long before analysts, vendors or journalists were coining terms like Digitalization, Identity Relationship Management or Customer IAM, several industries were already confronted with large-scale Identity and Access management (IAM) environments. Due to the character of their businesses they were challenged with the storage of huge amounts of identity data while serving massive volumes of both read and write requests at a constantly high access speed. Especially providers of telecommunication infrastructure like voice or data services typically handle identity data for several millions of subscribers. This information is leveraged for various purposes: One highly essential task focuses on controlling which subscribers are permitted to access which services and keeping track which resources they have used. This is typically done in highly specialized AAA (Triple-A) systems providing real-time Authentication (who?), Authorization (what?) and Accounting (how many?) services.
As this forms the basis for the actual core business processes, performance, availability, reliability and security are of utmost importance. Therefore, telco operators have always been in the forefront of designing and implementing highly redundant, scalable, sustainable special-purpose IAM systems as directory or database systems capable of fulfilling their unique requirements.
But several other systems traditionally need access to various subsets of subscriber=customer data: Customer Relationship Management (CRM) systems are the foundation for sales and help desks processes, while this information needs to be merged with AAA-data to produce e.g. the monthly bills. But apart from the traditional help desk systems, where customers call and want to interact with helpdesk personnel, the service landscape has changed dramatically: Many telco operators have transformed into being full service providers of communication and entertainment services, e.g. IPTV. In parallel subscribers have more and more gotten used to online portals for self-service access to their operator’s product portfolio. Having online access to their billing information, while being able to change, extend or cancel their subscriptions has become the new normal. This of course requires strong security mechanisms, especially rock-solid authentication and authorisation functionalities, while this is also true for ordering immediate access to streaming a blockbuster movie or gaining access to live coverage of their favourite sports event directly from the set-top box. These devices among money others (tablets, mobile phones or even gaming consoles) represent the identities individual subscribers and are of course more sources for additional billing information as well.
Providing a large-scale IAM system comes with many promises and requirements: gaining better insight into subscriber data through big data analytics might lead to efficient and agile business decisions and new products. The resulting information might be even more valuable when own subscriber data is intelligently merged with information provided by third parties (e.g. financial data, market research) and even social data, e.g. from Facebook, Google or Twitter logins. On the other hand, the privacy, security and reliability of sensitive information provided to the operators by subscribers is highly important. An example for that is when mobile devices are used for mobile, online payments (which is already done for example by Swisscom with their Easypay system) or secure mobile authentication (e.g. as a second factor) in the not so far future.
In large-scale IAM environment we observe that the traditional use case scenarios don’t go away, while they are constantly complemented with completely new requirements and business models. New technical requirements (new access methods, new devices, optimized performance, new data processing like big data analytics and lots more) are the results from such developments. And this often introduces the need for compliance to new sets of legal or regulatory requirements. All of this has to be adequately implemented in parallel, while existing requirements continue to be fulfilled, but usually with rising numbers of subscribers and increasing volumes of access requests.
With the traditional business models of providing mere access to voice or data services getting more and more irrelevant, telco operators have to constantly re-invent themselves and their business models. Existing and changing IAM systems for large numbers of customers and subscribers might turn out to be one of their biggest challenges but also their most significant asset to provide added value to their subscribers and new customer groups in the future.
