CISSP & CCSP Securit
Key CISSP, CCSP and CISA domain terms. Free practice questions at https://www.ex
| Question | Answer |
|---|---|
| CIA Triad | Confidentiality, Integrity and Availability - the three core goals of every information security program, tested heavily in CISSP Domain 1. |
| Risk = ? | Threat x Vulnerability x Asset Value (impact). Residual risk is what remains after controls are applied. |
| Due Care vs Due Diligence | Due diligence is researching and planning the right controls; due care is actually implementing and maintaining them. |
| Bell-LaPadula model | A confidentiality model: no read up (simple security), no write down (star property). |
| Biba model | An integrity model: no read down, no write up - the inverse of Bell-LaPadula. |
| RTO vs RPO | RTO is how fast a system must be restored; RPO is how much data loss is acceptable, measured backwards from the incident. |

| Cloud shared responsibility model | In IaaS the provider secures the hypervisor and below; the customer secures OS, apps and data. Core CCSP Domain 5 concept. |
| Free CCSP practice test | Cloud Security Professional practice questions and domain drills: |
| Data dispersion (CCSP) | Splitting encrypted data into fragments (bit splitting) across multiple storage nodes so no single node holds usable data. |
| Type 1 vs Type 2 hypervisor | Type 1 runs directly on bare metal (ESXi, Hyper-V); Type 2 runs on top of a host OS and has a larger attack surface. |
| CISA audit evidence | Evidence reliability ranks: auditor-obtained direct evidence is strongest, then external third party, then internal client records. |

| Kerberos | A ticket-based SSO authentication protocol using a KDC; vulnerable to golden ticket and pass-the-ticket attacks. |
| Defence in depth | Layering independent controls so failure of one control does not expose the asset - administrative, technical and physical. |
| Qualitative vs quantitative risk | Quantitative uses dollar figures (SLE, ARO, ALE); qualitative uses ranked scales like high/medium/low. |
