DESCRIPTION:DELDroid: An Automated System for Determination and Enforcement
  of Least Privilege Architecture in Android\n\nModern mobile platforms rel
 y on a permission model to guard the system’s resources and apps. In And
 roid\, since the permissions are granted at the granularity of apps\, and 
 all components belonging to an app inherit those permissions\, an app’s 
 components are typically overprivileged\, i.e.\, components are granted mo
 re privileges than they need to complete their tasks. Systematic violation
  of least-privilege principle in Android has shown to be the root cause of
  many security vulnerabilities.\n\nTo mitigate this issue\, we have develo
 ped DELDROID\, an automated system for determination of least privilege ar
 chitecture in Android and its enforcement at runtime. A key contribution o
 f our approach is the ability to limit the privileges granted to apps with
 out the need to modify them. DELDROID utilizes static program analysis tec
 hniques to extract the exact privileges each component needs for providing
  its functionality. A Multiple-Domain Matrix representation of the system
 ’s architecture is then used to automatically analyze the security postu
 re of the system and derive its least-privilege architecture. Our experime
 nts on hundreds of real-world apps corroborate DELDROID’s ability in eff
 ectively establishing the least-privilege architecture and its benefits in
  alleviating the security threats.\n\nCo-sponsored by: IEEE OC Computer So
