Abstract:

In order to address the increasingly serious cloud-native container security threats arising from large-scale cloud migration of systems, the ISM method merging IPFS, DEMATEL, and method were proposed to identify the key tactical factors influencing cloud-native container security threats and their hierarchical logical relationships from the security intruder perspective. The findings of this research are as follows: the centrality and causality of the persistence and privilege escalation tactical phases are high, positioning them at the core of the entire cloud-native security threat landscape. Security attacks during these two phases require high-priority attention. Threat attacks during the execution and persistence tactical phases constitute essential factors in cloud-native container security. The threats during the initial access, credential theft, and lateral movement tactical phases have the most direct impact on cloud-native container security. In comparison with traditional and triangular fuzzy sets improved DEMATEL-ISM, our proposed method has better performance in identifying container security-related critical factors.

Key words: interval pythagorean fuzzy set (IPFS), decision-making trial and evaluation laboratory (DEMATEL), interpretative structural modeling (ISM), container security threats, critical tactical factors
