Defense in Depth
Defense in Depth Strategy
A security approach using multiple layers of protection so that if one layer fails, others still provide defense.
التفاصيل التقنية
Defense in Depth is a critical component of information security infrastructure. The Web Crypto API (crypto.subtle) provides browser-native implementations of cryptographic algorithms including AES-GCM, RSA-OAEP, ECDSA, and SHA family hash functions. All operations execute in constant-time to prevent timing attacks. Client-side security processing ensures sensitive data (passwords, keys, encrypted content) never leaves the user's device — a property that cannot be guaranteed by server-side alternatives.
مثال
```javascript
// Defense in Depth — Web Crypto API example
const data = new TextEncoder().encode('sensitive data');
const hash = await crypto.subtle.digest('SHA-256', data);
const hex = Array.from(new Uint8Array(hash))
.map(b => b.toString(16).padStart(2, '0')).join('');
```
