Mempelajari SOC design, SIEM/SOAR architecture, detection architecture, dan merancang operasi keamanan yang scalable dan efektif

Setelah di episode 15 kita mempelajari vendor & technology selection, pada episode ini kita dalami security operations architecture — bagaimana mendesain SOC, SIEM/SOAR, dan detection architecture. Security architect harus memastikan operasi keamanan dirancang untuk scalability dan efektivitas.
Mengapa SecOps architecture penting? Karena SOC yang tidak terdesain dengan baik akan tenggelam dalam alert volume tinggi, tool sprawl, dan manual processes.
| Model | Deskripsi | Best For |
|---|---|---|
| Centralized | Single SOC, all locations | Medium enterprise |
| Distributed | SOC per region | Large global enterprise |
| Virtual | Remote SOC | Cost optimization |
| Hybrid | Central + distributed | Balanced approach |
| Layer | Tools |
|---|---|
| Collection | Filebeat, Fluentd |
| SIEM | Wazuh, Splunk, Elastic |
| EDR | CrowdStrike, Defender |
| SOAR | TheHive, Shuffle |
| Case Management | Jira, ServiceNow |
| Pattern | Use Case |
|---|---|
| Single instance | Small org |
| Distributed | Large enterprise |
| Cloud-native | Cloud-first |
| Hybrid | Mixed environment |
Tip
SIEM architecture harus dirancang untuk scale. Mulai dari volume data yang diharapkan, lalu pilih arsitektur yang sesuai. Over-provisioned SIEM membuang uang; under-provided SIEM kehilangan data.
| Layer | Fungsi |
|---|---|
| Network detection | IDS/IPS, NDR |
| Endpoint detection | EDR/XDR |
| Cloud detection | Cloud-native (GuardDuty, Defender) |
| Application detection | WAF, RASP |
| Identity detection | UBA, identity threat |
| Practice | Detail |
|---|---|
| Version control | Git-based detection rules |
| Peer review | PR-based rule changes |
| Testing | Atomic Red Team validation |
| Tuning | Regular FP reduction |
| System | Integration |
|---|---|
| SIEM | Alert forwarding |
| EDR | Endpoint actions |
| Firewall | Block IP/domain |
| Ticketing | Case management |
| Notification | Email, Slack, Teams |
| Level | Activities |
|---|---|
| Manual | All human |
| Assisted | Enrichment automated |
| Automated | Response automated |
| Autonomous | AI-driven response |
Note
SOAR architecture harus dirancang untuk interoperability. Setiap tool harus memiliki API yang bisa diintegrasikan. Vendor lock-in di SOAR layer sangat berisiko.
Inti yang harus dibawa pulang:
Di episode 17 selanjutnya kita akan membahas cloud-native & platform security — K8s security architecture, service mesh, dan supply chain security.
