The past year has taught enterprises that trusting a device just because it is connected to a corporate network is a bad idea. When an endpoint is left unmanaged, the organization becomes vulnerable to attack. This issue is highlighted by the widespread adoption of remote and dispersed workforces.
Zero trust ensures data usage and access are secured by understanding the flow of data and its significance, and by tracking all activities around it. As a protective model, zero trust creates a barrier around employees and their systems rather than networks and applications, allowing it to secure remote environments at scale.
However, zero trust knowledge is limited, and the first potential obstacle, according to a recent National Security Agency study, is a lack of full enterprise support, from leadership, managers, or users.
IT security departments of several organizations do not have the confidence enforce it with their existing security technologies. Their concerns center on their current infrastructure, which is complicated today and can include multiple servers and internal and third-party applications operating in multiple data centers or multi-clouds.
Making improvements that comply with zero trust protocols can be time and cost intensive, and this has been a big barrier to the adoption.
Committing to zero trust entails determining where the main security risks are in the current business environment and comprehending data flow. It’s difficult to create a program that tackles risks and enables controls to be implemented without being able to clearly identify the micro perimeter.

Access management policies should clearly prioritize confidential data properties, including where they are stored and who uses them. For zero confidence to be genuinely successful, organizations must apply it to all aspects of their infrastructure.
Securing the Critical Components
DNS, DHCP, and IP Address Management (IPAM), collectively known as DDI, may be a good place to start.
DDI are essential components of any network and a main transaction enabler. They are a part of cyber criminals’ attack surface, but they also play a key role in allowing zero trust architectures for application and access networking networks, and they have some distinct benefits.
Given businesses’ aversion to making significant improvements to their current systems, DDI may help them protect their networks and applications without requiring a major redesign or a change in how multiple devices interact with the network. It can, on the other hand, be the starting point for creating shared trust policies and providing a single pane of glass view across the network to fill in any coverage gaps.
DevSecOps teams can use software-defined DDI to easily orchestrate and control their DDI implementations as part of their overall application and network infrastructure, as well as simplify zero trust and network policies.
This provides them with a number of security and operational advantages, including the elimination of configuration anomalies caused by human error, better version control, and greatly improved application performance, thanks to traffic steering capabilities that can be instantly executed.
The Need for a Change in Mindset
Switching to zero confidence would provide significant benefits to businesses contemplating the protection of their remote employees or transitioning to a hybrid working model. Employees will need to change their attitude and be willing to provide additional security if they want to access specific data or are refused access due to a vulnerability. Simultaneously, IT and security departments will no longer be able to consider anything behind the firewall to be safe.
Enterprises must look past the obstacles and focus on the ever-increasing risks. Zero trust concepts are one of the most powerful obstacles to security vulnerabilities as network structures become more complex and distributed.
Zero trust can protect the enterprise both internally and externally, regardless of where individuals, applications, or networks are located, since it includes all elements of the system, not just security solutions.
