The bottom line: Cybersecurity must originate from network infrastructure and combine Zero-Trust, segmentation, cloud-native security and automated anomaly detection, rather than stacking isolated protective solutions.
Traditional perimeter security is no longer sufficient — NTT DATA recommends integrating security mechanisms directly into network architecture. Given cloud services, home office work and distributed applications, infrastructure itself must become a defense layer.
The classical security strategy with defined network boundaries no longer works. Cloud platforms, mobile work and decentralized applications dissolve the previous perimeter architecture. The consequence: attackers exploit this blurring while companies continue to concentrate their defenses primarily at the network entrance.
NTT DATA sees the network itself as a central defense layer. Concretely, this means: security functions must be built into existing systems, not added afterwards. Companies should disable unnecessary services, segment access and encrypt all data transfers. The Zero-Trust principle forbids blind trust in devices, users or services — even within the company. Network segmentation limits lateral movement after compromise. When selecting technology partners, it becomes relevant whether vendors have already integrated security and governance requirements into their products.
For multi-cloud and hybrid environments, Secure-Service-Edge technologies are recommended, which enforce security policies independently of location — in the office, home office or on the go. This creates transparency and centralized control over all access.
The enormous volume of telemetry and log data from modern networks requires observability solutions and AIOps approaches. They automate processes, detect anomalies early and significantly reduce response times to threats. Christian Koch from NTT DATA DACH emphasizes: the threat landscape cannot be completely controlled. What matters is how resilient companies build their infrastructure — technically, through governance rules, employee training and documented processes.
