Bu durum, zafiyetlerin ge\u00e7 ke\u015ffedilmesine, maliyetli d\u00fczeltmelere ve teslimat s\u00fcrelerinin uzamas\u0131na neden oluyordu. DevSecOps ise, g\u00fcvenli\u011fi “sol tarafa kayd\u0131rma” (shift-left) prensibiyle, tasar\u0131m a\u015famas\u0131ndan itibaren devreye sokar. Bu sayede, g\u00fcvenlik a\u00e7\u0131klar\u0131 erken tespit edilip giderilir, b\u00f6ylece \u00fcretim ortam\u0131nda kar\u015f\u0131la\u015f\u0131lacak riskler minimize edilir.<\/p>\n

- EnvSecOps eski sistemleri (legacy systems) nas\u0131l ele al\u0131r?<\/dt>\n
- EnvSecOps, eski sistemlerin modern ortamlara ta\u015f\u0131nmas\u0131 (lift-and-shift) veya kademeli olarak modernize edilmesi (re-platforming\/re-factoring) s\u00fcre\u00e7lerinde g\u00fcvenlik entegrasyonuna odaklan\u0131r. Mevcut eski sistemler i\u00e7in ise, \u00e7al\u0131\u015fma zaman\u0131 izleme, a\u011f segmentasyonu ve eri\u015fim kontrollerinin g\u00fc\u00e7lendirilmesi gibi EnvSecOps prensipleri uygulanarak riskler azalt\u0131labilir. Hedef, eski sistemleri yeni, g\u00fcvenli ortamlara ba\u011flarken ortaya \u00e7\u0131kabilecek g\u00fcvenlik a\u00e7\u0131klar\u0131n\u0131 en aza indirmektir.<\/dd>\n<\/dl>\n
