Implementing zero-trust security models in legacy IT infrastructures requires a strategic approach to enhance security without disrupting existing operations:
Start by assessing your current infrastructure and segmenting your network to create smaller, more manageable security zones. This limits the potential impact of breaches.
Implement robust IAM policies to ensure that only authenticated and authorized users can access critical resources. Use multi-factor authentication (MFA) to enhance security.
Utilize micro-segmentation to create granular security policies that restrict access to sensitive data and applications based on the principle of least privilege.
Deploy continuous monitoring and threat detection tools to identify and respond to suspicious activities in real-time, ensuring ongoing security and compliance.
