Apa iku threat modeling?

Question

Accepted Answer

**Threat modeling** minangka proses terstruktur kanggo ngenali potensial **security threats** menyang sistem lan nglancakake pertahanan — sistematis mikir apa sing bisa salah, sapa sing bisa nyerang, lan kepiye. Iki minangka pendekatan proaktif kanggo security, ditindakake nalika desain.

## Apa iku threat modeling

```text
Threat modeling = systematically analyzing a system to find SECURITY THREATS and decide
how to mitigate them — BEFORE building (or as a review):
  → understand the system (data flows, components, trust boundaries, assets)
  → identify THREATS (what could an attacker do? where are the weak points?)
  → assess and prioritize risks; plan MITIGATIONS
→ proactive security: design defenses by thinking like an attacker, early.
```

## Pendekatan umum (lan STRIDE)

```text
Typical questions:
  1. What are we building? (diagram the system, data flows, trust boundaries)
  2. What can go wrong? (identify threats)
  3. What do we do about it? (mitigations)
  4. Did we do a good job? (review)
STRIDE → a framework for categorizing threats:
  Spoofing, Tampering, Repudiation, Information disclosure, Denial of service,
  Elevation of privilege
→ helps systematically consider threat types per component/data flow.
```

## Mengapa lan kapan

```text
✓ PROACTIVE → find/address security issues at DESIGN time (cheaper than after a breach)
✓ Focuses security effort on real RISKS (the most important threats to the system)
✓ Especially valuable for sensitive/critical systems and significant new features
✓ Part of "security by design" / shift-left → build security in, not bolt on
→ A structured way to think about and improve a system's security posture.
```

## Mengapa penting

Nangerteni threat modeling minangka pengetahuan tingkat senior sing berharga amerga iki minangka **pendekatan proaktif, terstruktur kanggo security** sing nemokake lan ngatasi threats nalika desain, mula penting kanggo mbangun sistem sing aman kanthi mateng.

Threat modeling — **sistematis nganalisa sistem kanggo ngenali security threats lan nglancakake mitigasi**, kanthi nangerteni sistem (data flows, components, trust boundaries, assets), ngenali apa sing bisa salah, lan mutusake kepiye cara membela — minangka pendekatan proaktif, desain-time kanggo security (mikir kaya panyerang nang awal, tinimbang nanggepi breaches).

Nangerteni **pendekatan umum** (pitakonan: apa sing kita bangun, apa sing bisa salah, apa sing kita lakukan babagan iku, apa sing kita gawé kanthi apik — diagram sistem lan ngenali threats) lan framework kaya **STRIDE** (kategorisasi threats minangka Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, lan Elevation of privilege — membantu sistematis ngenali jenis-jenis threats) menyediakan struktur kanggo nindakake kanthi efektif tinimbang ad-hoc.

Nangerteni **mengapa lan kapan** threat modeling iku berharga — dadi proaktif (nemokake lan ngatasi masalah nalika desain, luwih murah tinimbang sawise breach), fokus usaha security nang risks nyata, paling penting, luwih berharga kanggo sistem sensitif/kritis lan fitur signifikan, lan embodying **security by design / shift-left** (mbangun security tinimbang melekatake) — ngrepresentasikake pemikiran security sing mateng.

Threat modeling minangka carane tim sing mateng sistematis nambah postur security bab desain, ngatasi threats sadurunge dadi vulnerabilities.

Sawise security proaktif, desain-time (nemokake lan ngatasi threats sadurunge mbangun) luwih efektif lan murah tinimbang reactive security, lan sawise threat modeling menyediakan carane terstruktur kanggo nindakake iki (sistematis ngenali threats lan mitigasi, nggunakake framework kaya STRIDE), lan sawise nangerteni iki mrefleksikake praktik security mateng, nangerteni threat modeling minangka pengetahuan tingkat senior sing berharga — praktik security proaktif penting kanggo mbangun sistem aman kanthi mateng, embodying security-by-design, lan reflecting pemikiran security terstruktur, attacker-minded sing dikarepke kanggo peran senior sing ndesain lan nreview sistem kanggo security.
