🔍01 Identify
Understand your digital assets and risks
Before you can take appropriate protective measures, you need to know exactly what digital assets your company owns and where potential vulnerabilities lie. The identification phase is the foundation of any solid security strategy.
What does "Identify" mean specifically?
📊 Asset Management
What hardware and software are being used? Who uses them and where?
🏢 Business Environment
Which business processes are critical? Which data is essential?
📋 Governance
What security policies exist? What requirements must be met?
⚠️ Risk Assessment
Where are the greatest risks? Which threats are most likely?
