"数据出站策略与隐私合规（DLP/PII检测）最佳实践"

数据出站策略与隐私合规（DLP/PII检测）最佳实践概述对外发送或记录的数据需进行敏感信息检测与脱敏，配合策略门禁与审计，实现隐私合规与防泄漏。PII检测规则const piiPatterns: Record<string, RegExp> = { email: /\b[\w.%+-]+@[\w.-]+\.[A-Za-z]{2,}\b/g, phone: /\b\+?\d{1,3}[-\s]?\d{6,14}\b/g, idcard: /\b\d{15}(\d{2}[0-9X])?\b/g } function detectPII(text: string): string[] { const hits: string[] = [] for (const [name, re] of Object.entries(piiPatterns)) { if (re.test(text)) hits.push(name) } return hits } 脱敏与替换function maskPII(text: string): string { return text .replace(piiPatterns.email, '***@***') .replace(piiPatterns.phone, '********') .replace(piiPatterns.idcard, '****************') } 出站策略门禁type OutboundPolicy = { allowPII: boolean; destinations: string[] } function gateOutbound(payload: string, policy: OutboundPolicy, dest: string): { allowed: boolean; sanitized: string } { if (!policy.destinations.includes(dest)) return { allowed: false, sanitized: '' } const hits = detectPII(payload) if (hits.length > 0 && !policy.allowPII) { return { allowed: false, sanitized: maskPII(payload) } } return { allowed: true, sanitized: payload } } 审计与留存type OutboundAudit = { dest: string; blocked: boolean; categories: string[]; timestamp: string } function auditOutbound(dest: string, blocked: boolean, categories: string[]): OutboundAudit { return { dest, blocked, categories, timestamp: new Date().toISOString() } } 运维要点将PII检测与脱敏前置到出站与日志环节明确目的地白名单与是否允许PII的策略出站审计入库并留存以满足合规要求通过检测、脱敏与门禁，可在通用Web场景下实现数据出站的隐私合规治理。
