ABOUT ME

我是 Lex,專注於資訊安全與風險管理。

我具備銀行資訊部門與資安管理經驗,曾參與 弱點管理、SSL 憑證檢查、資安設備權限管理、資安稽核與合規、系統開發與維護 等工作。

同時,我持續透過實驗室環境研究 滲透測試、數位鑑識、Purple Team、Active Directory Security,將攻防技術轉化為容易理解、能實際執行的安全建議。

無論面對的是個人的帳號安全,還是企業的系統風險,我都希望先回答三個問題:

  1. What is actually at risk?
  2. How serious is the risk?
  3. What should you do next?
