itgc-testing

itgc-testing is a skill for Claude Code, Codex from guoliang1114-boop/AriaAI. It costs 34 tokens per session (4,012 once invoked), scanned A, original, MIT.

A skill for testing information-technology general controls, which are the basic safeguards around access, system changes, software development, and day-to-day IT operations. It uses the COBIT 2019 governance framework and can also refer to ISO 27001:2022.

In plain words
What is it for?
Use it to create IT control test matrices and workpapers, review policies and permissions, and analyze logs, changes, access, backups, incidents, and recovery procedures.
Why use it?
It gives audits a structured way to assess whether systems and the controls supporting business data are reliable and properly managed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

itgc-testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

IT一般控制测试 (ITGC Testing)

When To Use

  • 审计中依赖信息系统生成的报告或数据时,需要测试ITGC
  • SOX合规审计中IT系统支持财务报告流程时
  • 客户引入新系统或现有系统发生重大变更时
  • 需要评估自动化控制所依赖的IT环境可靠性时
  • 客户IT治理和风险管理需要评估时

Tools

  • write - 创建ITGC测试矩阵和工作底稿
  • read - 审阅IT政策、系统配置文档、用户权限清单
  • grep - 搜索系统日志、变更记录
  • bash - 执行权限分析脚本、日志比对

Framework

COBIT 2019 Framework References

ITGC四大领域与COBIT治理/管理目标的映射:

1. 访问控制 (Access to Programs and Data)

  • DSS05: Managed Security Services
  • DSS06: Managed Business Process Controls
  • 关注: 用户账号管理、权限分配、认证机制、特权账号、定期权限复核

2. 变更管理 (Program Change Management)

  • BAI06: Managed IT Changes
  • BAI07: Managed IT Change Acceptance and Transitioning
  • 关注: 变更请求、审批、开发、测试、上线、紧急变更

3. 系统开发 (Program Development)

  • BAI02: Managed Requirements Definition
  • BAI03: Managed Solutions Identification and Build
  • BAI04: Managed Solution Availability
  • BAI05: Managed Organizational Change
  • BAI11: Managed Projects
  • 关注: 需求定义、开发流程、用户验收测试、上线审批、数据迁移

4. IT运维 (Computer Operations)

ISO 27001:2022 参考

ITGC测试亦可参考ISO 27001 Annex A控制项:

  • A.5: Organizational controls (安全策略、职责分离)
  • A.6: People controls (安全意识、入职离职)
  • A.7: Physical controls (机房安全)
  • A.8: Technological controls (访问控制、加密、变更管理)

SOX/PCAOB相关要求

参照PCAOB AS 2201 §36-38及IT Audit Guidance:

  • 当审计师依赖系统生成的信息时,需要测试ITGC
  • ITGC有效性是自动化控制可信赖的前提条件
  • 需要评估ITGC对应用层面控制的影响

  2. 了解系统架构(本地部署/云端/混合)
  3. 确定系统所有者和IT负责人
  4. 获取IT组织架构和职责分工
  5. 了解IT外包情况(如适用)

Step 2: ITGC范围界定

  1. 列出所有相关IT系统及组件
  2. 评估各系统对财务报告的重要性
  3. 确定需要测试的系统范围
  4. 识别各系统适用的ITGC领域
  5. 评估第三方服务商ITGC(SOC报告审阅)

Step 3: 控制识别与穿行

  1. 获取IT政策和程序文档
  2. 访谈IT管理层和关键人员
  3. 识别各领域的关键控制点
  4. 执行穿行测试验证控制设计
  5. 编制ITGC风险控制矩阵

Step 4: 控制测试执行

  1. 根据控制频率确定样本量
  2. 获取测试证据(配置截图、日志、审批记录)
  3. 执行测试并记录结果
  4. 对发现的偏差进行调查
  5. 评估控制缺陷等级

Step 5: 汇总与评估

  1. 汇总各系统/各领域测试结果
  2. 评估ITGC总体有效性
  3. 确定对应用层面控制和实质性程序的影响
  4. 编制ITGC测试报告

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
