Introduction to Disaster Recovery and Business Continuity

As information availability increases in the PASIS architecture, which feature decreases as a consequence?

  • A Confidentiality
  • B Durability
  • C Nonrepudiation
  • D Latency
Explanation

Increasing the number of PASIS shares improves availability because it is more likely that enough shares can be reached for reconstruction. It decreases confidentiality because additional shares provide more opportunities for an attacker to obtain the information.
