Siber Olay Müdahale Süreçlerinde Açık Kaynaklı Otomasyon: Low-Code Tabanlı Sürekli Tespit, Doğrulama ve Müdahale Mimarisi

Öz

Siber tehditler giderek daha karmaşık hale gelmektedir; kuruluşlar personel eksikliği ve mali kısıtlamalar nedeniyle güvenlik politikalarının uygulanmasında zorluk çekmektedir. Manuel yaklaşımlar, yüksek "bekleme süresi" ve yanlış alarmlara yol açarak kuruluşları siber saldırılar açısından risklere maruz bırakmaktadır. Bu çalışma, kamu ve özel kuruluşlar için maliyet etkin, açık kaynaklı ve düşük kodlu bir güvenlik orkestrasyonu, otomasyonu ve yanıtı çerçevesi önermektedir. Önerilen sistem, Wazuh, n8n, OpenVAS ve GLPI çözümlerini içermekte olup, "sıfır dokunuş" yaklaşımına göre çalışan Docker mikro hizmet tabanlı mimari kullanılarak uygulanmaktadır.. Sunulan çözüm, yüksek vasıflı personele duyulan ihtiyacı en aza indirerek Türkiye'nin ulusal siber güvenlik altyapısını mikro düzeyde geliştirmesine yardımcı olacaktır.

Open-Source Automation in Cyber Incident Response Processes: A Low-Code-Based Continuous Detection, Verification, and Response Architecture

Öz

Cyber threats are becoming increasingly complex; organizations face difficulties in implementing security policies due to staffing shortages and financial constraints. Manual approaches lead to high "wait times" and false alarms, exposing organizations to risks from cyberattacks. This study proposes a cost-effective, open-source, and lowcode Security Orchestration, Automation, and Response framework for public and private organizations. The proposed system incorporates Wazuh, n8n, OpenVAS, and GLPI solutions and is implemented using a Docker microservice-based architecture operating according to a "zero-touch" approach. The presented solution will help Türkiye develop its national cybersecurity infrastructure at the micro level by minimizing the need for highly skilled personnel.
