Replication package: Modern Frontiers in Security Requirements Engineering

This is the data-extraction replication package for the systematic review "Modern Frontiers in Security Requirements Engineering" The review examined 46 sources spanning maturity models and classical threat-modelling frameworks (STRIDE, PASTA, LINDDUN, Secure by Design), requirements-native security methodologies (SQUARE, SREP, STORE, and related approaches), AI-augmented threat-modelling and formal-reasoning approaches, and meta-level reviews or empirical studies on security requirements engineering practice. This package contains: Corpus (all 46 sources): the full reference list with category assignment, numbered to match the paper's own reference list. Scoring (32 sources): the four-criterion data extraction (concrete guidance, dedicated tool support, non-technical stakeholder accessibility, end-to-end elicitation-to-assurance coverage) applied to every method- or tool-proposing source, with live formulas reproducing the paper's aggregate statistics. Search Strategy: the search terms, platforms, and inclusion/exclusion criteria used to assemble the corpus. No human-subjects or experimental data are involved; this is a literature review, and the data shared here is the review's own source corpus and classification scheme.
