Apa iku model keamanan Zero Trust?

Question

Accepted Answer

**Zero Trust** minangka model keamanan adhedhasar prinsip **ora perlu dipercaya, tansaya verifikasi** — tinimbang mempercayai apa wae adhedhasar lokasi jaringan (ing dalam utawa ing njaba), saben permintaan akses diautentikasi, diotorisasi, lan diverifikasi. Iki ngatasi kegagalan keamanan tradisional adhedhasar perimeter.

## Problema karo keamanan perimeter

```text
TRADITIONAL ("castle and moat") security:
  → a strong PERIMETER (firewall); trust everything INSIDE the network
  ✗ once an attacker gets IN (breach, insider, compromised device), they move FREELY
    (lateral movement) — the inside is implicitly trusted
  ✗ doesn't fit modern reality: cloud, remote work, mobile, distributed services (no clear
    perimeter)
```

## Zero Trust: ora perlu dipercaya, tansaya verifikasi

```text
ZERO TRUST assumes NO implicit trust — verify EVERY request regardless of location:
  → AUTHENTICATE & AUTHORIZE every access (every request, every resource), inside or out
  → "assume breach" — act as if attackers are already inside
  → LEAST PRIVILEGE → minimal access; verify continuously (identity, device, context)
  → MICRO-SEGMENTATION → limit lateral movement (a breach in one area is contained)
→ trust is never assumed based on network location; it's continuously established.
```

## Komponen utama

```text
✓ Strong IDENTITY & authentication (MFA); verify the user AND device
✓ Least-privilege, fine-grained access control (per resource); continuous verification
✓ Micro-segmentation; encrypt everything; monitor/log all access (detect anomalies)
✓ Context-aware policies (who, what, where, device posture, behavior)
```

## Apa sing penting

Pamahaman babagan model keamanan Zero Trust minangka ilmu tingkat senior sing berharga amarga iki minangka **pendekatan keamanan modern sing penting** sing ngatasi kegagalan keamanan perimeter tradisional, saya suwe diadopsi kanggo lingkungan modern, mula relevan kanggo arsitektur sing aman.

Pamahaman babagan **problema karo keamanan perimeter** — model tradisional "kubu lan wedi" sing mempercayai kabeh sing ana ing jaringan, sing gagal amarga mengko penyerang bisa lolos (liwat breach, insider, utawa piranti sing rusak) lan **bisa berpindah-pindah (lateral movement)**, lan sing ora cocog karo realitas modern (cloud, remote work, mobile, layanan terdistribusi tanpa perimeter sing jelas) — njlasake apa mengapa pendekatan anyar diperlukan. **Zero Trust** ngatasi iki karo prinsip **ora perlu dipercaya, tansaya verifikasi**: ora nganggep ana kepercayaan implisit, mengotentikasi lan mengotorisasi **saben permintaan tanpa perduli lokasi**, **nganggep ana breach** (tumindak minangka yen penyerang wis ana ing dalam), ngetrapake **least privilege** karo verifikasi terus-terusan, lan nggunakake **micro-segmentation** kanggo ngebatesi breach lan nglimit lateral movement.

Pamahaman babagan prinsip-prinsip iki — lan yen kepercayaan ora perlu dianggep adhedhasar lokasi jaringan nanging terus-terusan ditegakake — menggambarake inti saka model.

Pamahaman babagan **komponen utama** — identitas kuat lan otentikasi (MFA, verifikasi user lan piranti), least-privilege fine-grained access control, micro-segmentation, enkripsi, monitoring lengkap, lan context-aware policies — nggambarake carane Zero Trust diimplementasikan.

Zero Trust saya suwe dadi standar modern kanggo arsitektur keamanan, utamane nalika cloud lan remote work nglenyapake perimeter tradisional, mula dadi ilmu sing relevan kanggo desain aman saiki.

Amarga keamanan perimeter tradisional gagal ing lingkungan modern sing terdistribusi/cloud/remote (ngidini lateral movement sawise breach) lan Zero Trust ngatasi iki karo prinsip ora-perlu-dipercaya-tansaya-verifikasi (verifikasi terus-terusan, least privilege, anggep-breach, micro-segmentation), lan amarga saya suwe diadopsi minangka pendekatan keamanan modern, pamahaman babagan model keamanan Zero Trust minangka ilmu tingkat senior sing berharga — paradigma keamanan modern sing penting ngatasi kegagalan keamanan perimeter, saya suwe relevan kanggo lingkungan cloud lan terdistribusi, lan nggambarake pemikiran arsitektur keamanan kontemporer sing dikarepake kanggo peran senior ngrancang keamanan kanggo sistem modern.
