Diversification. Although the concepts of SAN/NAS convergence offer a compelling glimpse into one possible storage future, businesses can be leery of one-size-fits-all platforms. NAS use cases are diversifying, and the needs of each specific use case must be carefully evaluated. Some NAS offerings are well suited for backups and archives but might not possess the performance, scale and reliability attributes needed for hosting virtualized environments, data analytics, AI/ML computing and demanding databases. As the variety of NAS products grows, it's important for IT and business leaders to select the NAS platform that best meets the needs of the task at hand.

[May 29, 2009] "Key Exchange." By Michael Vizard (eWEEK) and Kevin Bocek (Director of Product Management, Thales e-Security). From eWEEK (May 14, 2009). "In this eWEEK podcast hosted by Mike Vizard, the Director of product marketing for Thales, Kevin Bocek [WWW], talks about the impact that a new KMIP (Key Management Interoperability Protocol) standard will have on spurring widespread adoption of encryption. Storage managers, data center operators, and IT security teams are demanding new support for full encryption next step in data security. With encryption comes the need for integrated key management within databases and other applications to cover business continuity and SLA requirements. Encryption is now being deployed as critical part of enterprise infrastructure. The KMIP interoperability specification is a big step for the industry in terms of supporting development of interoperable security products. The standard will be applicable for key management systems and servers, for both software-based applications (databases, web servers) and hardware (tape drives, disk arrays, network switches)... Encryption is is now being deployed to a much larger extent than over before, so key management needs to be commensurable... We've seen an end to crypto wars (e.g., certificate formats) so the focus is on reliability and recoverability of data: we need key management that's stable and tested. Key management is moving away from the point applications (from concern about individual keys) to policy and compliance concerns. The question isn't so much "where are my keys?" but "what are my key management policies? how can I pass an audit?... Data center operators need to be able to know and prove that their encryption supports recoverable data. Where to encrypt: software, hardware, both? It depends: what's the risk: what's threat to the data, and what are the consequeneces of compromise (data breach). If you have high-value transactions, the data may need to be protected (encrypted) early and throughout its life cycle; but some data becomes sensitive only at certain points. For storage systems, encryption is now moving from being an option to being an expectation/requirement. Many devices are shipped with hardware that supports encryption - even if it's not activated initially. Similarly, with databases: expectation is growing that information is encrypted in the database. Cost factors are coming down as encryption gets embedded in applications and hardware devices. A challenge however is management of keys in terms of automation and auditing for operations. KMIP interoperability will help a lot..." [source MP3]
[May 07, 2009] "OASIS Group Aims to Simplify Crypto-Key Management." By Tom Espiner. From ZDNet.co.uk. "Open-standards consortium OASIS has formed a group to devise a standard aimed at allowing encryption products to work easily with business applications and with each other. Group members include IBM, Cisco, EMC, HP, PGP Corporation, Symantec, and the US National Institute of Standards and Technology (NIST). The OASIS group, called the Key Management Interoperability Protocol (KMIP) Technical Committee, will aim to define a single protocol for communication between encryption systems and enterprise applications, to cover such things as email, databases and storage devices. The companies participating in the new group submitted a key management interoperability standard to OASIS in February. Key management interoperability is vital for businesses to be able to successfully implement encryption and protect data, according to Jamie Cowper, PGP's EMEA marketing manager. 'With the best will in the world, businesses are never going to be using a single encryption product, or a single company to provide that,' Cowper told ZDNet UK on Thursday. 'It's great to see key members of the security and encryption community working together and recognising the business need for key management interoperability.' Key management is a problem for businesses, according to Cowper. As more documents are encrypted throughout an enterprise or shared with third parties, keys proliferate. Managing the administration of those keys until they are revoked is a problem that is exacerbated as companies grow, said Cowper. 'Encryption is really just a standard,' said Cowper. 'To strongly protect and decrypt in an automated way is the clever bit'..."
[March 03, 2009] "Towards a Common Key Management Standard: Making Encryption Work." By Staff. From Computer Business Review Online. "Enterprises are increasingly aware of the need to implement encryption in order to protect their information assets, but this has emphasized the challenges around interoperability and effective key lifecycle management. As a result, a group of storage and security vendors has announced the key management interoperability protocol, which is intended to standardize key management interfaces. The growing trend towards remote and mobile working, combined with the ubiquity of internet access and the prevalence of removable storage, has created a significant increase in the channels through which data can be lost. Unsurprisingly, this growth in loss vectors has resulted in a torrent of high-profile incidents that have led to valuable data being compromised. The higher visibility of the risks of data loss and the awareness of their effects on the bottom line (especially in this challenging economic environment) have encouraged greater investments from enterprises in information protection technologies, particularly encryption. Attempts to resolve these concerns have often been ad hoc and have therefore failed to remove obstacles to the wider and deeper adoption of encryption solutions. This may all change thanks to the welcome introduction of the proposed KMIP standard that has been formulated by a group of prominent enterprise storage and security vendors including Brocade, EMC, HP, IBM, LSI, [NetApp,] Seagate, and Thales. KMIP is intended to standardize and simplify the interactions between disparate key management mechanisms and encryption methods across the entire IT infrastructure. The long list of vendors which have already committed to the standard will almost guarantee its ratification and make it very likely to emerge as the foremost protocol in this marketplace. However, KMIP is still at an early stage of its development and is many steps away from being adopted by the industry..." Similarly, posted to CBR Security by Alaa Owaineh, March 25, 2009. 2ff7e9595c
