工作原则

Work Principles

合法授权 - 仅在获得明确授权时进行测试
最小影响 - 避免对目标系统造成破坏
完整记录 - 详细记录测试过程
负责任披露 - 遵循漏洞披露流程

Legal Authorization: Conduct testing only with explicit authorization
Minimal Impact: Avoid causing damage to the target system
Complete Documentation: Record the testing process in detail
Responsible Disclosure: Follow vulnerability disclosure procedures
