Threat modeling nima ne?

Question

Accepted Answer

**Threat modeling** wata tsarin tsari ne don gano abubuwan barazana da suka iya kasuwa ga tsarin da kuma tsara kariya — tunani cikin tsari game da abin da zai iya faruwa, wane zai iya kai hari, da kuma yadda. Gida ce don tsarin tsaron, wanda ake yi lokacin tsarawa.

## Abin da threat modeling ne

```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.
```

## Tsarin da aka saba amfani da shi (da 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.
```

## Dalilin da lokacin

```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.

## Me ya sa ya matuwa

Gane threat modeling wani ilimi ne mai mahimmanci ga ƴan senior tunda shi ne **tsari gida, tsari tsada ga tsaron** wanda ke nemo da tunka kasuwanci a lokacin tsarawa, saboda haka yana muhimman gina tsarin duwatsu cikakke.

Threat modeling — **bincike tsari na tsari don gano barazanan tsaron da kuma tsara juriya**, ta hanyar fahimtar tsarin (zamani data, sassa, iyakan aminci, abubuwa), gano abin da zai iya faruwa, da kuma yanke shawarar yadda za a tsara — wakiltar tsari gida, lokacin tsarawa ga tsaron (tunani kamar maharin a jiya, maimakon amsa ga karnatsin).

Gane **tsarin da aka saba amfani da shi** (matakai: menene muke gina, menene zai iya faruwa, menene muke buɗe sai, sanye muke buɗe daidai — zana tsari da gano barazana) da tsarin kamar **STRIDE** (rangwar barazana a matsayin Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, da Elevation of privilege — taimaka tunani cikakke game da nau'iyar barazana) ya ba tsari ne saboda yin shi inganci maimakon ba wuri ba.

Gane **dalilin da lokacin** threat modeling yana da muhimmanci — kasua (nemo da tunka kasuwanci a lokacin tsarawa, mafi jaje da kasua baje), mayar hankali tsaron abu ga ainihin, mafi mahimmancin hadarin, zama mai muhimmanci domin tsarin da tsada da kuma fasali mahimmanci, da kuma baje da matsayin **security by design / shift-left** (gina tsaron maimakon kwanto) — nuna ɗami tsada mahimmanci.

Threat modeling yadda tunani da ƴan gida suke ingana tsarasu cikakke lokacin tsarawa, tunka kasuwanci kafar su zama yanku.

Tunda tsari gida, lokacin tsarawa tsaron (nemo da tunka kasuwanci kafar gina) yana da karfia da mafi jaje fiye da tsari amsa, kuma tunda threat modeling ya ba hanya tsari ta buɗe haka (tunani cikakke game da gano barazana da juriya, amfani tsarin kamar STRIDE), kuma tunda gane shi ya nuna tunani tsada baki, gane threat modeling yana da mahimmanci ga ƴan senior ilimi — aikin tsaron gida mahimmanci domin gina tsarin duwatsu cikakke ingana, baje da matsayin security-by-design, da nuna tunani tsaron baki, attacker-minded wanda ake buɗe don ƴan senior wanda suke tsara da duba tsarin don tsaron.
