In a May 2012 survey by the Ponemon Institute, 66 percent said they are not confident their organization would be able to detect the loss or theft of sensitive personal information contained in systems operated by third parties, including cloud providers. In addition, the majority are not confident that their organization would be able detect the loss or theft of sensitive personal information in their company’s production environment.
Which aspect of data security for your cloud solution is most important?
1. Is it to protect the data in copies of production/cloud applications used for test or training purposes? For example, do you need to secure data in your Salesforce.com Sandbox?
2. Is it to protect the data so that a user will see data based on her/his role, privileges, location and data privacy rules?
3. Is it to protect the data before it gets to the cloud?
As compliance continues to drive people to action, compliance with contractual agreements, especially for the cloud infrastructure continues to drive investment. In addition, many organizations are supporting Salesforce.com as well as packaged solutions such as Oracle eBusiness, Peoplesoft, SAP, and Siebel.
Of the available data protection solutions, tokenization has been used and is well known for supporting PCI data and preserving the format and width of a table column. But because many tokenization solutions today require creating database views or changing application source code, it has been difficult for organizations to support packaged applications that don’t allow these changes. In addition, databases and applications take a measurable performance hit to process tokens.
What might work better is to dynamically tokenize data before it gets to the cloud. So there would be a transparent layer between the cloud and on-premise data integration that would replace the sensitive data with tokens. In this way, additional code to the application would not be required.
In the Ponemon survey, most said the best control is to dynamically mask sensitive information based on the user’s privilege level. After dynamically masking sensitive data, people said encrypting all sensitive information contained in the record is the best option.
The strange thing is that people recognize there is a problem but are not spending accordingly. In the same survey from Ponemon, 69% of organizations find it difficult to restrict user access to sensitive information in IT and business environments. However, only 33% say they have adequate budgets to invest in the necessary solutions to reduce the insider threat.
Is this an opportunity for you?
