This means implementing network segmentation that isolates critical business functions from general corporate networks. When attackers gain access to email systems or file shares, they shouldn’t automatically have pathways to manufacturing controls or financial systems. NIST’s Zero Trust Architecture guidelines provide a framework, but implementation requires deep understanding of your operational dependencies.
Your backup and recovery systems need their own security considerations. I’ve seen organizations invest millions in backup infrastructure only to discover that attackers had persistent access to their recovery environments for months. This requires implementing offline backup strategies, maintaining air-gapped recovery environments and regularly testing restoration procedures under simulated attack conditions.
The cloud paradox: Opportunity and vulnerability
Cloud services present both opportunities and challenges for business continuity planning. While platforms like AWS, Azure and Google Cloud offer geographic redundancy and professional security management, they also create dependencies on external providers and internet connectivity.
