Identification and Validation of Social Media Socio-Technical Information Security Factors with Respect to Usable-Security Principles

The goal of this manuscript is to present a research finding, based on a study conducted to identify, examine, and validate Social Media (SM) socio-technical information security factors, in line with usable-security principles. The study followed literature search techniques, as well as theoretical and empirical methods of factor validation. The strategy used in literature search includes Boolean keywords search, and citation guides, using mainly web of science databases. As guided by study objectives, 9 SM socio-technical factors were identified, verified and validated. Both theoretical and empirical validation processes were followed. Thus, a theoretical validity test was conducted on 45 Likert scale items, involving 10 subject experts. From the score ratings of the experts, Content Validity Index (CVI) was calculated to determine the degree to which the identified factors exhibit appropriate items for the construct being measured, and 7 factors attained an adequate level of validity index. However, for reliability test, 32 respondents and 45 Likert scale items were used. Whereby, Cronbach’s alpha coefficient (α-values) were generated using SPSS. Subsequently, 8 factors attained an adequate level of reliability. Overall, the validated factors include;1) usability—visibility, learnability, and satisfaction;2) education and training—help and documentation;3) SM technology development—error handling, and revocability;4) information security —security, privacy, and expressiveness. In this case, the confirmed factors would add knowledge by providing a theoretical basis for rationalizing information security requirements on SM usage.

Fuzzy Based Decision-Making Approach for Estimating Usable-Security of Healthcare Web Applications

Usability and security are often considered contradictory in nature.One has a negative impact on the other.In order to satisfy the needs of users with the security perspective,the relationship and trade-offs among security and usability must be distinguished.Security practitioners are working on developing new approaches that would help to secure healthcare web applications as well increase usability of the web applications.In the same league,the present research endeavour is premised on the usable-security of healthcare web applications.For a compatible blend of usability and security that would fulfill the users’requirments,this research proposes an integration of the Fuzzy AHP-TOPSIS method for assessing usable-security of healthcare web applications.Since the estimation of security-usability accrately is also a decision making problem,the study employs Multiple Criteria Decision Analysis(MCDA)for selecting the most decisive attributes of usability as well as security.Furthermore,this study also pinpoints the highest priority attributes that can strengthen the usable-security of the healthcare web applications.The effectiveness of the suggested method has been tested on the healthcare web applications of local hospitals in Mecca,Saudi Arabia.The results corroborate that Fuzzy AHP-TOPSIS is indeed a reliable technique that will help the developers to design a healthcare web applications that delivers optimum usable-security.
