SQL 注入、XSS、CSRF……这些安全漏洞你的代码里有吗？一文掌握 OWASP Top 10 漏洞的原理和防御方法。
SQL injection, XSS, CSRF — are these vulnerabilities in your code? Master the principles and defenses of OWASP Top 10 vulnerabilities in one article.
为什么开发者必须懂安全？安全不是运维的事，是开发者写每一行代码时就要考虑的事。一个 SQL 注入漏洞，可能让整个数据库被脱走。最常见的 5 个漏洞1. SQL 注入永远不要拼接 SQL 字符串。用参数化查询（PreparedStatement）或 ORM 框架（MyBatis-Plus）自动防御。2. XSS（跨站脚本）用户输入的内容在页面上展示时，必须做 HTML 转义。富文本内容要用白名单过滤，只保留安全的 HTML 标签。3. CSRF（跨站请求伪造）前后端分离 + JWT 认证天然防御 CSRF，因为 Token 在 Header 里而不是 Cookie。4. 敏感数据泄露密码用 BCrypt 加密存储，API 响应不要返回密码字段，配置文件里的密钥用环境变量。5. 权限控制缺失光验证登录不够，还要验证用户是否有权限操作该资源。普通用户不能访问管理员接口。iDev 的安全实践我们在每个项目中默认执行安全 checklist：参数校验、SQL 防注入、XSS 过滤、密码加密、JWT 鉴权、CORS 限制、HTTPS 强制。安全不是可选项，是交付标准。
Why Developers Must Understand SecuritySecurity isn't just an ops concern — it's something developers must consider with every line of code. One SQL injection vulnerability could lead to the entire database being exfiltrated.Top 5 Most Common Vulnerabilities1. SQL InjectionNever concatenate SQL strings. Use parameterized queries (PreparedStatement) or ORM frameworks (MyBatis-Plus) for automatic defense.2. XSS (Cross-Site Scripting)User-submitted content displayed on pages must be HTML-escaped. Rich text content needs whitelist filtering — only allow safe HTML tags.3. CSRF (Cross-Site Request Forgery)Frontend-backend separation + JWT authentication naturally defends against CSRF, since tokens are in headers, not cookies.4. Sensitive Data ExposureStore passwords with BCrypt, never return password fields in API responses, use environment variables for config secrets.5. Missing Access ControlValidating login isn't enough — verify the user has permission for the specific resource. Regular users must not access admin endpoints.iDev's Security PracticesEvery project follows a default security checklist: input validation, SQL injection prevention, XSS filtering, password encryption, JWT auth, CORS restrictions, HTTPS enforcement. Security is not optional — it's a delivery standard.
