Cloud Security Alliance: 10 Ways To Achieve Access Control For Big Data

A look at granular access control of the big data security and privacy.
2 of 11

Choose appropriate level of granularity required
 
Goal: Balance complexity and granularity of access control

As with most things in security, sliding the lever too far to either side can leave things too exposed or too difficult to use. Controlling access to big data is no different in this sense; picking the right model will be based on the criticality and sensitivity of the data, the feasibility of labeling the data, and the ability for the team to define, apply, and enforce the supporting policies.

From the handbook: 
- Why it matters: The use of fine-grained access controls requires an increased complexity in data labeling and security attribute management, while coarse-grained access controls demand data modeling.  
- How to do it: Evaluate the policies that govern data access, looking for restrictions on data or schema elements that should be protected.


Additional reading: 
From an auditor's perspective, 'Effective access control doesn't just put up barriers to entry -- it also enables for more effective and granular visibility into what specific employees are doing within specific systems.'

The concept of application security is well known, but application security testing and remediation processes remain unbalanced. Most organizations are confident in their approach to AppSec, although others seem to have no approach at all. Read this report to find out more.
