Detecting And Responding

telagod/code-abyss

This is for blue and purple team work: writing Sigma and YARA rules, tuning SIEM alert noise, responding to incidents, doing forensics, and running threat hunts. It enforces a strict methodology where every detection rule must answer what, why, false positive rate, and response action before going live. The skill routes you through three reference docs depending on whether you're building detections, handling an active incident, or hunting threats. It's opinionated about treating detection rules like production code with git, tests, and CI, and it won't let you ship a rule with more than 5% false positives. Maps everything back to ATT&CK techniques and includes forensic chain of custody practices. Use this when you're actually building or operating a security detection stack, not for architectural threat modeling or application security work.

蓝队检测与响应 · 镇魔盾

判断先于执行:决定「是否做 / 选什么 / 如何取舍」(栈、方案、架构、权衡)前,先读领域判断内核 skills/_kernel/security/SKILL.md——它管 judgment,本秘典管 execution;冲突时以内核判断为准。

检测是工程,不是运气。每条规则必须能回答四问:what / why / FP rate / response。 站在防御侧,把告警当代码维护、把事件当事故管理、把狩猎当假设验证。 信级:项目日志/EDR 原始事件 > Sigma/YARA 规则库 > ATT&CK 官方矩阵 > 训练记忆(标 [unverified])。

路由

意图秘典触发词
SIEM/EDR 规则与调优siem-and-edrSigma, YARA, Splunk, Elastic, Sentinel, EDR, LOLBins, detection-as-code
事件响应与取证incident-responseIR, NIST 800-61, triage, chain of custody, Volatility, memory, runbook, postmortem
威胁狩猎与紫队threat-huntinghunt, hypothesis, IOC, IOA, TTP, ATT&CK, Atomic Red Team, Caldera, 蜜罐

执行链

检测:日志源 → 规则编写 → 告警分级 → 调优降噪 → 覆盖矩阵
响应:识别 → 遏制 → 根因 → 清除 → 恢复 → 复盘
狩猎:假设 → 数据源 → 验证 → 规则化 → 自动化 → 紫队闭环

每环必须可回答「我看的是哪条日志?我证伪的是哪条假设?我下一步动作是什么?」

何时使用

场景用不用

处理已发生入侵、取证✅ incident-response—
假设驱动狩猎 / 紫队演练✅ threat-hunting—
ATT&CK 检测覆盖打分✅ threat-hunting—
设计应用层防御代码❌defending-applications
渗透测试、写 PoC❌securing-systems (pentest/red-team)
威胁建模、IAM 架构❌architecting-security
代码静态扫描胶水❌analyzing-security
云配置基线、K8s 加固❌securing-cloud-and-supply-chain

联动

  • securing-systems/red-team:攻方 TTP 是本 skill 检测规则的设计输入。
  • securing-systems/threat-intel:IOC/CTI 投喂本 skill 的规则与狩猎假设。
  • architecting-security/threat-modeling:威胁模型的 detective control 在本 skill 落地。
  • analyzing-security:本 skill 产出的 detection-as-code 接入 CI 门禁。
  • automating-devops/observability:日志/指标/链路三支柱的安全维。

铁律

  1. 无噪不出闸 — 任何规则上线前必须有基线 + FP rate 测量;FP > 5% 直接打回调优,不准带病上线。
  2. 不证伪即假设 — 狩猎必须有可证伪的假设;找不到不是结论,是数据缺失或假设错。
  3. 取证不破坏现场 — 先采易失证据(内存/网络/进程),再动磁盘;写阻断器 + 哈希链 + 时间戳三件套必须齐。
  4. 检测即代码 — 规则进 git、有 unit test、过 CI、有 owner;改规则等同改生产代码。
  5. 闭环到 ATT&CK — 每条规则、每次事件、每次狩猎必须映射到 ATT&CK 技术 ID;无 ID 不归档。

输出约束

  • 规则示例必须给完整 frontmatter + detection + condition + 反例说明(为什么不这样写)。
  • 命令示例标注操作系统与权限要求(root / SYSTEM / 普通用户)。
  • 日志样例脱敏:IP 用 192.0.2.0/24、域名用 example.com、用户名用 <analyst>。
  • 每条检测规则必须附 FP 来源清单与响应动作(containment / enrichment / kill)。
