应用安全性是保护软件免受威胁的实践——构建和维护能够抵抗攻击、保护数据并安全运行的应用程序。这很重要,因为安全漏洞会造成严重后果:数据盗窃、经济损失和信任破裂。
应用安全性的覆盖范围
text
App security = protecting software and its data from threats throughout the lifecycle:
→ secure CODING (avoid vulnerabilities like injection, XSS)
→ AUTHENTICATION (who are you?) and AUTHORIZATION (what can you do?)
→ protecting DATA (encryption in transit and at rest)
→ input VALIDATION, secure configuration, dependency security, etc.
→ "Security" is a quality of the whole system, not a single feature.
安全性为何重要

✓ Breaches are SEVERE — stolen data (personal, financial), financial loss, downtime
✓ TRUST & reputation — a breach damages user trust and the company's reputation
✓ LEGAL/compliance — regulations (GDPR, etc.) require protecting data; fines for failures
✓ Attacks are CONSTANT — apps are continuously targeted (automated attacks, bots)
→ Security failures are among the most costly and damaging problems software can have.
