#iso27001 consists of 2 parts: 1) a PROCESS to manage information security risks, called the Information Security Management System (or ISMS) 2) a list of CONTROLS to mitigate (or control) the risks you've identified, called "Annex A" #infosec #cybersecurity #isms
The #ISMS risk mgt process looks like this: 1) Identify and Analyse Risks 2) Select and Implement Controls 3) Monitor execution of Controls 4) Evaluate effectiveness 5) Re-analyse Risks and Adjust Controls 👉 NEXT: Start implementing ... #infosec #cybersecurity #iso27001
