|
AWS SECURITY — ENCRYPTION 🔐 AWS CloudHSM Cloud मा उपलब्ध Dedicated Hardware Security Module — Encryption key generate, store र use गर्नको लागि। |
|
🔑 Core Concept — CloudHSM के हो? |
|
| Feature | CloudHSM |
|---|---|
| HSM Type | Dedicated (Single Customer only) — अरूसँग share हुँदैन |
| Security Level | FIPS 140-2 Level 3 ← यो exam मा 100% आउँछ! |
| Key Control | Full Customer Control — AWS ले keys access गर्न सक्दैन |
| Managed By | AWS = hardware, patching, HA मात्र | Keys = Customer |
| Used For | High-security encryption — Bank, Government, Healthcare |
|
🎓 FIPS 140-2 Level 3 भनेको के हो? (Exam Key) ▸ FIPS = Federal Information Processing Standard — US Government को security standard ▸ Level 3 = Physical tamper protection — कोहीले hardware खोल्न खोज्यो भने keys automatically delete हुन्छ ▸ KMS = FIPS Level 2 | CloudHSM = FIPS Level 3 (higher security) 👉 Bank वा Government ले Level 3 माग्छ = CloudHSM answer |
