Microsegmentation and Zero trust Best practices

Zero trust architecture is the best way to ensure that all systems, networks, and users are safe. It requires continuous authentication for your devices or else you could potentially have an attacker on your hands.

To ensure that your organization can maintain a secure environment, an architecture should be implemented using multiple integrated technology solutions.

The process of Micro-segmentation is a very granular one. And it’s put in place at the lowest possible level which addresses minutiae that will determine success long term. Considering this basic ask from micro segmentations, there are best practices needed when implementing them into workflows. these need attention to detail for their successful execution.

Let’s have a look at some of the best practices for zero trust and microsegmentation best practices.

Zero Trust Best Practices 

Understand your cloud architecture

Mapping out your network topology is essential to know who and what devices are accessing it. As well as understanding how those users will interact with the system. It can help identify any potential vulnerabilities in order for you to build an architecture that protects against them. this way security becomes part of product design.

Consider any network as hostile—whether it is your local area or an unsecured public Wi-Fi connection. Also, take into account existing services that were not designed for a zero-trust architecture. And may not be able to defend themselves against attacks on the system they are running on.

Device Authentication

Device identity is the foundation of a secure architecture. Without it, you cannot authenticate or authorize devices in any way and therefore, your security will be compromised. Make sure that device identities are strong and unique to avoid being vulnerable.

Adopt network segmentation

If you want to be truly secure, it’s important that no one from outside your network has access rights. This includes both physical or wireless vulnerabilities in addition to the people on staff who handle data remotely for businesses with remote work policies.

The implementation of VLANs, firewalls, and other types of security controls such as IDS/IPS can be used to segment your network into groups which are then protected by specific policies. These technologies protect against both external threats from outside networks or inside ones where employees could launch attacks on their own computers with botnet software designed for corporate servers. Allowing them access without being noticed.

Microsegmentation Best Practices 

Define Parameter

The architecture should be well-defined to ensure early results. To do this, enterprises need to define their objectives driven by business applications. And categorization/identification of consumers or end users who use these services. This will enable them to create boundaries for information flow as well as what type is transferred across those fences.

Application-centric approach

The goal of an enterprise is to create a safe space for employees where they can do their jobs without being worried about what’s going on outside that context. Creating boundaries by the application will help you achieve this. And the first step in doing so should be establishing visibility into all your applications with clear guidelines as well defined internal. And external communications policies – not just email but also chats or other means like instant messages too.

Level of access

It is important to think of the lowest level of privilege when designing your application. You should define this first and then work up from there for each service type or user group that will use it.
