Five Approaches to Implement a Zero Trust NetworkZero Trust Networks (ZTN) can handle cyberattacks better than traditional networks and are necessary to strengthen an organization’s privacy and security standards.

FREMONT, CA: Organizations are vulnerable to online threats and are experiencing an increased number of cyberattacks now, more than ever. Zero Trust Networks (ZTN) can handle these challenges in a better way than most traditional networks. As organizations experience digital transformation, it becomes necessary to strengthen their privacy and security standards. Organizations must include trust principles in their corporate strategies.

Five approaches for implementing a ZTN are as follows:

Identifying protection surface

Organizations need to protect their data and privacy. An organization’s data is an essential element for ZTN, privacy requirements and its guidelines. To identify an organization’s protection surface, it is crucial to understand what type of data is essential for an organization and where this data is located.

Mapping connections

A typical network architecture diagram that describes network traffic flow is inadequate. A complete map of the numerous links throughout the network is also required for ZTN to be effective.  Zero Trust necessitates a detailed mapping of all programs in use, related data sets, and data transmission connections, with enough detail to decide where security controls are required.

Micro-segmenting protection surface

The focus now switches to micro-segmenting the protective surface with techniques and technologies. Deep packet inspection tools, firewalls, intrusion prevention systems, and data loss prevention tools are the most often used information security tools today. These tools can help you set up a Zero Trust environment, but they need to be improved in order to assess and control traffic around the stack.

Implementing zero-trust policies

One of the most significant and time-consuming factors in building an effective ZTN is developing and executing policies. It necessitates that businesses fully comprehend their protection surface to accept or deny acceptable traffic flow. Security tools should be used to implement these granular standards across all network workloads.

Regular monitoring

All resources will be better safeguarded if all logs are directed to a centralized location and monitored for harmful activities. Deep packet inspection tools and some other network security monitoring technology can help with this. Automation and orchestration can also be used to monitor and filter undesirable traffic properly. Because Zero Trust is a never-ending process, analyzing all logs and making improvements to obtain more visibility into all resources should be done on a regular basis.
