Secret Management Journey - Here Be Dragons aka Secret Dragons


Published on

Secret Management Journey - In the beginning there was a file and it contained all the passwords in the plain text, but then someone stole all the passwords, so we don't do that anymore. In this talk I will explore how secret management has evolved over the years, what is the common path to maturity, what good looks like and why "Just use HashiCorp Vault" is a good heuristic. Explore with me the perils of storing secrets in Jenkins, how ansible-vault leads to disasters and where does CyberArk Conjur sit in all of this.
