RE: Hiding sensitive EBS column data from certain users

Just need to highlight the problem in prod.

The rules applied can actually cause problems with the COTS applications like EBS that has their own internal security architecture.

Just need to do lots of testing.

For production environments, technologies which mask data in-flight, including Oracle's data redaction and SQL Server's dynamic data masking are appropriate solutions when a portion of the user community should not have access to certain data.

In development or testing (a.k.a. non-production) environments, there is no reason for anyone to have access to confidential data, including database administrators and systems administrators, partially because of the movement of development and testing environments to out-sourced, off-shore, or cloud environments. Masking data at-rest is the appropriate solution for non-production environments by permanently and irreversibly obfuscating data in datafiles, thus removing any value to intruders.

Following the implementation of GDPR <https://en.wikipedia.org/wiki/General_Data_Protection_Regulation> in Europe this past May, CCPA <https://www.caprivacy.org/> in California has already been signed into law, with more countries and states to follow. The professional honor code to which all of IT has adhered for the past 40-50 years is no longer sufficient to protect confidential data. Essentially, unmasked data in non-production is becoming a liability to the DBAs, developers, and testers who work with it, because at some point, all these laws may hold individuals (as well as organizations) liable for the damages from data breaches. I expect that, like SOX, individual liability will begin at the top of the organization (i.e. CEO, CFO, etc) but with examples like Snowden there is no reason why those lower in the hierarchy cannot be targeted.

What version of the database are you running?  

In 12.1 there is RAS Security (VPD 2.0) that also does column level data masking at no extra cost, but you have to create/implement the rules yourself.

Normally you control PROD by standard security controls, but you can implement RAS against report users if they are landing on your primary database. Just need to make sure anything you implement it doesn’t affect base EBS apps.

Hello List,  

Is there anyway to hide data of sensitive columns in Oracle EBS (v12.2) to certain users? I thought of VPD, but, it seems, it has different approaches in EBS. Something like, personalizing the form to hide the values of the columns, though not sure.  

Appreciate if any EBS expert can shed some light on this.  

Thanks in advance,
