RSM analysis based cloud access security broker: a systematic literature review.

Area of Science:

• Cloud Computing Security
• Information Security Management
• Software Engineering

Background:

• Cloud Access Security Brokers (CASB) are crucial for extending organizational security to cloud services.
• Existing research often lacks a focus on the end-user or client perspective in CASB implementation.
• Understanding CASB design and deployment is vital for effective cloud security strategy.

Purpose of the Study:

• To systematically review and analyze existing literature on Cloud Access Security Brokers (CASB).
• To identify and categorize methods and approaches used in CASB design and engineering.
• To evaluate CASB studies from a customer-centric viewpoint, identifying research gaps.

Main Methods:

• Conducted a systematic literature review (SLR) of 20 studies published between 2011 and 2021.
• Extracted keywords from research questions to identify relevant papers from various sources.
• Analyzed selected studies based on motivation, usefulness, engineering approach, and decision methodology.

Main Results:

• Identified a range of engineering efforts including market-based solutions, middleware, toolkits, and conceptual frameworks.
• Principal Component Analysis (PCA) identified five key parameters influencing CASB.
• Research Surface Methodology (RSM) developed an empirical model with R²=0.90, indicating significant variable influence.

Conclusions:

• Cloud Access Security Broker (CASB) technology is still in a formative stage of development.
• Despite advancements, significant challenges in CASB implementation and effectiveness remain.
• This review provides a customer-focused understanding and a novel taxonomy for CASBs.
