在定义协调规则之前，选择一个可以自动评估和执行这些规则的静态分析工具。
手动检查效率低下且容易出错，因此应尽可能实现自动化。
以下静态分析工具可与 CloudFormation 和 SAM 模板一起使用。选择并实施最适合您的项目的工具：
cfn-lint
检查有效的资源属性值、资源依赖性和 AWS 资源设置。
请参阅评估规则： cfn-lint/docs/rules.md 。
cfn_nag
检查 CloudFormation 模板中定义的 AWS 资源设置。
使用“cfn_nag_rules”命令查看评估的规则。当前规则列在下面的“CFN_NAG 规则列表（截至 2025 年 1 月 3 日）”中。
CloudFormation Guard
在部署之前验证 CloudFormation 模板。
使用符合 CISSP、NIST 800-53 和 PCI DSS 等安全框架的规则集： aws-guard-rules-registry 。
YAML（VS 代码扩展）
检查 YAML 文件语法。
Visual Studio Code 用户和工作区设置
可以使用设置文件来统一换行和缩进的设置，例如 EditorConfig 。

Not sure!? W26 Elastic Load Balancer should have access logging enabled W27 Security Groups found ingress with port range instead of just a single port W28 Resource found with an explicit name, this disallows updates that require replacement of this resource W29 Security Groups found egress with port range instead of just a single port W31 S3 Bucket likely should not have a public read acl W32 CodeBuild project should specify an EncryptionKey value W33 EC2 Subnet should not have MapPublicIpOnLaunch set to true W34 Batch Job Definition Container Properties should not have Privileged set to true W35 S3 Bucket should have access logging configured W36 Security group rules without a description obscure their purpose and may lead to bad practices in ensuring they only allow traffic from the ports and sources/destinations required.

另外， [2024 年 3 月更新]云工程师 Visual Studio Code 推荐插件汇总 | Moderniser.repo ，在集成开发环境中与编辑器协调时自动评估。CloudFormation Guard没有插件，因此需要手动执行工具。
CloudFormation Linter
Cfn-Nag Linter
在vscode上启用该插件后，代码实时静态分析，并会显示“警告（黄色）”或“错误（红色）”。
这可以让您快速找到并修改违反协调规则的部分。
对于“警告（黄色）”或“错误（红色）”中显示的结果，如果设计中指定的值是值，则设置明显恶化。
示例）如何忽略 CFN-Lint 在所有模板中检测到的错误显示
在工作目录中创建配置文件 .cfnlinTrc.yml ，并将忽略的规则ID指定为 include_checks 。
.cfnlinTrc.yml

文件配置取决于“Cloudformation 模板还是 SAM 模板？”以及“在一个存储库中管理多个模板？”
在一个存储库中管理多个模板时，建议您为每个模板创建一个目录，并将模板文件放置在该目录中。
管理一个模板时，建议您将模板文件直接放在存储库根目录下。
作为基本策略，模板文件采用yaml文件，文件扩展名统一为 *.yml 。
*.yml
模板文件有两种类型：JSON和YAML格式，但考虑到可读性和可编辑性，建议您使用YAML格式描述。
以下是在 CloudFormation 模板中管理一个存储库中的一个模板时的文件配置示例。
aws cloudFormation 命令的选项 --cli-input-json 如果您使用该选项指定参数，您将能够创建 JSON 格式的参数文件并将其放置在 parameters 目录中。
aws cloudFormation
--cli-input-json

AWSTemplateFormatVersion: 2010-09-09 Description: cloudformation-cicd/template.yml
模板中描述的资源、参数、条件、映射、输出等逻辑名称均统一为密码大小写（单词仅大写，无换行符）， ${用途}${AWS 资源名称}${2 位序列号} 。但允许使用 EC2、SSM 等缩写。
${用途}${AWS 资源名称}${2 位序列号}
示例：如果 EC2 实例用作垫脚石服务器 ( AWS::EC2::Instance )，则为 BastionInstance01 。
AWS::EC2::Instance
BastionInstance01
嵌入函数原则上使用缩写符号。
示例） 值：！Ref AWS::NoValue
值：！Ref AWS::NoValue
但如果需要嵌套多个函数，也可以容忍使用完整的函数名。
