Imagine knowing everything about a customer before they come through the door – name, preferences and interests, buying history, who they are connected to, where they live, and more. That kind of intelligence makes it easy to strike up a conversation with the customer and make the right recommendations that can lead to sales. The more you know, the more chances you have to win.
Data encryption is the bedrock of cybersecurity. Encrypted data remains worthless ciphertext without access to encryption keys; hardware security modules (HSM) are well-established means for securing those keys in on-premises data centers. Data security teams are well-versed in the process of purchasing, provisioning and managing those HSMs.
Residing on disks, in computer memory or transferred by wire or wireless, data increasingly drives global economies. Try going a day without internet access. How isolated do you feel when you’re out of cell-tower range? Your day is driven by data, and the value of data is defined by its context and usage.
To remedy this embarrassment and bring a greater degree of security, the payment card industry as well as real-time payment platforms are moving to tokenization—a process by which a surrogate value in the form of a series of randomly-generated numbers, known as a “token,” replaces the primary account number.
When we talk to companies around the world, a common topic of discussion is the transformational nature of cloud technologies. In a very short time, the cloud has disrupted every aspect of how IT infrastructure, resources and software are deployed and managed. While there’s near-universal agreement on the economic benefits of this, it’s not all good news: In these discussions, the conversation invariably turns toward the growing challenges of cloud security management - in particular, the management of the encryption keys that are fundamental to cloud security.
The cloud strategy you adopt—private, hybrid, public or multicloud—is a key factor in the decision as to which encryption key management strategy will work best for your enterprise. For best results, your key strategy should fit your long-term cloud strategy and should be applied consistently across your enterprise.
Enterprises should consider a vendor-neutral HSM-as-a-Service that provides the protection and a service level agreement (SLA) to effectively support the “shared-responsibility” model between cloud providers and their customers.
Stored and accessible PII, which is broadly defined as any information that could be used to identify an individual, facilitates these transactions for all consumers. However, near-weekly reports of significant data breaches have raised concerns about the ability of retailers and other organizations to keep consumer records secure.
The best approach to delivering each of the aforementioned capabilities is an HSM as a Service (HSMaaS) solution. It leverages the established strengths of the cloud—wide availability, service on demand and scalability—to make encryption keys easy to implement and manage.
As you transition from on-premise computing to cloud computing, securing your data in the cloud is paramount. Since encryption is a preferred way to secure data, encryption key management is a critical concern. Cloud providers have responded to this need with two options: a hardware security module (HSM) or a key management service (KMS). Each approach features benefits and drawbacks.
