Intel Expressway Service Gateway and RSA DPM: Security without pain
Top security threats for 2013 include “hacktivism” attacks, botnet malware, distributed denial of service attacks, and identity theft. The problems are well known and yet there is still resistance to spending the capital on prevention measures. Intel® Expressway Service Gateway (ESG) and RSA Data Protection Manager (DPM) have partnered to provide a painless way to protect web services and sensitive data from threats.
The beauty of the solution is that existing services do not need to be modified. Service delivery of tokenization and key management is abstracted, secured and simplified. The Expressway Service Gateway provides features made to integrate, mediate, secure, and scale services in a dynamically changing Enterprise application perimeter that may include multiple security domains. Once deployed to the network edge in a software or hardware form factor, our service gateway combined with the DPM can safely expose existing REST APIs or SOAP web services. High speed data mediation capabilities for XML, JSON, binary, and legacy data enable existing web services to be exposed as REST APIs to meet growing mobile service demands.
Tokenization in the Expressway Service Gateway
When acting as a tokenization solution, ESG in conjunction with DPM can provide PCI Compliance through the configuration of a proxy tokenization and detokenization service. This configuration provides security without modification to existing services. Data is proxied through the service gateway and tokenized before it reaches existing services. All systems behind ESG are out of scope since PAN data never reaches them, only the tokenized data. In reverse, when data needs to be transmitted out with the original PAN data it can be securely proxied through the service gateway and the tokens are replaced with the original PANs. ESG supports a wide range of protocols, HTTP(S), JMS, IBM MQ, FTP(S), FILE, SFTP, RAW TCP/IP(S), and CUSTOM which allows it to handle the various types of traffic that needs to be tokenized/detokenized on the way in and out of a customer’s data center.
For retail applications, PCI Compliance can be achieved by intercepting url-encoded web requests containing PAN data, tokenizing and forwarding to the existing backend with no change needed to the back-end service. Bulk tokenization requests, transmitted over SFTP, can be proxied to allow for tokenization. ESG can batch large requests to run in parallel in order to optimize performance. The concepts applied to PAN data also work to secure patient health information (PHI) for healthcare applications.
Data Encryption Services
When working in conjunction with DPM for key management operations, ESG acts as a secure proxy gateway to sign/verify/encrypt/decrypt data as it enters or leaves a customer’s Data Center. The advantage here is that customers do not need to modify existing services to gain this functionality. It also allows larger amounts of data to be encrypted vs. smaller PAN credit card type numbers. It is extremely flexible and desired key and Token behavior can be set to each application needs. The data center encrypt/decrypt/sign/verify use case can be applied to cloud applications too. Requests to store data in the cloud can be intercepted and encrypted/decrypted with no modification to the cloud storage services.
