Forecasting the diffusion of ISO/IEC 27001: a Grey model approach

Abstract

PurposeThe aim of this paper is to present the first diffusion analysis of ISO/IEC 27001, the fourth most popular ISO certification at global level and the most important standard for information security.Design/methodology/approachTo achieve the purposes, the authors applied Grey Models (GM) – Even GM (1,1), Even GM (1,1,α,θ), Discrete GM (1,1), Discrete GM (1,1,α) – complemented by the relative growth rate and the doubling time indexes on the six most important countries in terms of issued certificates.FindingsResults show that a growing trend is likely to be expected in the years to come and that China will lead at country level.Originality/valueThe study contributes to the scientific debate by presenting the first diffusive analysis of ISO/IEC 27001 and by proposing a forecasting approach that to date has found little application in the field of international standards.

Evaluasi Keamanan Sistem Informasi Menggunakan Fuzzy FMEA Berbasis Framework ISO/IEC 27001:2013 untuk Meningkatkan Keamanan Informasi

“…Standar keamanan yang sering digunakan pada organisasi di dunia sebagai manajemen kebijakan dan pelaksanaan keamanan informasi organisasi yaitu ISO/IEC 27001. ISO/IEC 27001 membantu organisasi dalam mengembangkan dan memelihara Sistem Manajemen Keamanan Informasi (SMKI) di tingkat organisasi dan tetap menjadi salah satu alat manajemen risiko paling efektif untuk melawan miliaran serangan yang terjadi setiap tahun (Podrecca and Sartor 2023). ISO/EIC 27001 merupakan standar Internasional yang dipersiapkan untuk mengimplementasikan, membangun, memonitor, mengoperasikan serta merawat sistem manajemen keamanan informasi (SMKI) (Fathurohman and Witjaksono 2020).…”

Posterior Variance Test: Ex ante Evaluation of Grey Forecasting model

“…modes, a grey forecasting model outperformed the Crow/AMSAA reliability growth model in predicting system reliability growth parameters (Talafuse & Pohl, 2017). In 2023, Italian scholars performed the first diffusion analysis of ISO/IEC 27001 using the grey forecasting models (Podrecca & Sartor, 2023). Several grey forecasting models have been proposed to date.…”

“…EGM (1, 1, 𝛼, 𝜃) represents the even form of a grey model with a first-order differential equation containing one variable and weighted background value involving conformable fractional accumulation. It was proposed by Javed et al (2020), and has seen several interesting applications (see, e.g., Tulkinov, 2023;Podrecca & Sartor, 2023;Singh et al, 2022). Let the set of actual data is 𝑋 (0) = (𝑥 (0) (1), 𝑥 (0) (2), … 𝑥 (0) (𝑛)) , 𝑥 (0) (𝑘) ≥ 0, 𝑛 ≥ 4…”
