执行行业威胁态势评估

概述

行业特定威胁态势评估（Threat Landscape Assessment）通过研究哪些威胁行为者针对特定行业、其惯用攻击向量和 TTP（战术、技术和程序，Tactics, Techniques, and Procedures）、常被利用的漏洞、历史事件数据及新兴威胁，分析特定行业垂直领域（医疗、金融服务、能源、政府、制造业）所面临的网络威胁环境。该评估为风险管理、安全投入优先级排序和董事会级汇报提供可落地的情报支持。

前置条件

• Python 3.9+，安装 attackcti、requests、pandas、matplotlib 库
• 可访问威胁情报源（AlienVault OTX、MISP、厂商报告）
• MITRE ATT&CK 知识库用于 TTP 映射
• 行业 ISAC（信息共享与分析中心，Information Sharing and Analysis Center）会员资格（FS-ISAC、H-ISAC、E-ISAC 等）
• 了解行业特定监管要求

核心概念

行业定向攻击分析

不同行业面临不同的威胁画像。金融服务面临高级国家级威胁行为者（Lazarus Group）和专注于金融欺诈的网络犯罪组织。医疗行业面临利用紧迫性和遗留系统的勒索软件（Ransomware）组织。能源和关键基础设施面临具有破坏能力的国家级组织（TEMP.Veles、Sandworm）。政府部门面临以间谍活动为目的的 APT（高级持续性威胁，Advanced Persistent Threat）组织（APT29、APT28、Turla）。

威胁态势组成要素

全面评估包括：威胁行为者画像（针对该行业的组织）、攻击向量分析（观测到的初始访问方法）、TTP 映射（该行业常见技术）、漏洞态势（常被利用的 CVE）、事件趋势分析（泄露频率、影响、恢复时间）及新兴威胁（新组织、演变技术、供应链风险）。

情报来源

行业特定情报来源包括：ISAC、政府公告（CISA、FBI、NSA）、厂商威胁报告（CrowdStrike 年度威胁报告、Mandiant M-Trends、Verizon DBIR），以及行业特定攻击的学术研究。
