Define Monitoring Requirements

Where do we begin? Defining monitoring requirements is the first step towards robust security management. This task involves outlining what exactly needs to be monitored to maintain data integrity under ISO 27001. Consider the impacts of not having precise requirements; it’s like sailing without a map—a potential challenge, wouldn’t you say? By identifying your priorities, you’ll have a clear path ahead.

Identify key assets that require monitoring.
Assess current monitoring gaps.
Align monitoring needs with business objectives.
