From 47ee0c0242ea5b984ecf30bb070885a20fa75a66 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=EA=B9=80=EC=A7=84=EC=97=BD=20=28Nathan=29?= Date: Fri, 3 Apr 2026 16:40:44 +0900 Subject: [PATCH] feat: add AI Security & Zero Trust executable scripts, service-provider template Add missing executable check/fix scripts for AI Security and Zero Trust guidelines to achieve parity with CII and Robot Security, which already had complete scripts coverage. Changes: - Add scripts/ai-security/ (3 files: model-security-check, api-security-check, data-pipeline-check) - Add scripts/zero-trust/ (3 files: identity-check, network-check, visibility-check) - Add templates/ai-security/service-provider.md (27-item checklist) - All content synchronized across 8 skills (4 EN + 4 KO) - Fix pre-existing README validation failure by adding English CII technical table - Update validate-content.mjs to verify new directories and file counts - Clean up temp/ directory from git tracking Constraint: All scripts follow existing KISA guide structure (Source + Checklist refs + bash/PowerShell commands + Verification Checklist) Constraint: Content parity enforced across all 8 skill directories as required by validate-content.mjs Rejected: Adding language-specific secure coding templates (Go/Java/Rust) | pseudocode.md already covers these via language-agnostic patterns Confidence: high Scope-risk: moderate --- .gitignore | 1 + README.md | 25
