Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'github.com/russellhaering/goxmldsig' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で github.com/russellhaering/goxmldsig を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
