    Reducing Cyber Risk: Zero Trust Networks

    Reducing Cyber Risk Zero Trust Networks

    Zero trust networks are becoming increasingly important in organizations around the world due to their ability to provide sophisticated network security solutions to protect companies, organizations, and individuals from malicious actors. Zero trust networks are a response to the increasingly interconnected network of devices in today’s digital landscape, where traditional cybersecurity methods no longer offer sufficient protection. Rather than relying on perimeter-based defense mechanisms that assume all users and devices behind the perimeter walls can be trusted, zero trust network access employ a policy of “never trust, always verify” when it comes to granting access to resources both inside and outside the corporate network.

    What is a zero trust network

    A zero-trust network is a security concept that eliminates the idea of an untrusted outside and an implicitly trusted inside in favor of assuming that all entities, both internal and external to the network, are potentially malicious. This means that the security perimeter is pushed all the way back to individual users, devices and services on the network. With this model, no entity or user is automatically trusted; instead, access must be earned through authentication and authorization systems that verify identity and ensure users only have access to the resources they need.

    The benefits of a zero trust network

    Improved Visibility

    By leveraging zero trust architecture, organizations can also improve visibility into user activities on their networks. IT teams can monitor all attempted or successful connections made by any user on the network in order to detect suspicious behavior or threats quickly and efficiently. Additionally, organizations can utilize advanced analytics solutions such as machine learning and artificial intelligence to further enhance their threat detection capabilities.

    Simplify Access

    One of the benefits of zero-trust network is that it simplifies access management while providing users with granular control over who can gain access to which resources. This means IT teams no longer have to manage complex permissions for each user individually. Instead, policies are set at the network level for each group or user identity to grant appropriate levels of access. This enables organizations to fine-tune their network security posture by defining roles and capabilities for each user type in their environment.

    Increased Security

    A key security benefit of zero-trust implementation network is its ability to reduce the attack surface. By creating a system of access controls that ensures only trusted users and devices can submit access requests, zero-trust networks dramatically reduce the chances of malicious actors infiltrating your organization’s network. A zero-trust security model is designed to detect suspicious activity and send alerts in order to quickly identify any potential threats before damage can be done.

    Examples of Zero Trust Security

    Microsoft Azure Active Directory

    An example of a zero-trust system is Microsoft’s Azure Active Directory (AAD). AAD provides comprehensive single sign-on capabilities along with multifactor authentication features such as biometrics and two-factor authentication via SMS or phone calls. It also allows IT departments to maintain control over their systems by allowing them to create policies and apply restrictions based on organizational requirements and user roles.


    Finally, micro-segmentation is an important component of a zero trust strategy as well. Micro-segmentation involves breaking up public and private networks into smaller segments according to users’ roles and responsibilities, as well as their need for certain resources. This helps limit users’ visibility into other parts of the network, making it harder for attackers to move laterally through the network without being noticed. Furthermore, micro-segmentation allows administrators to quickly identify suspicious traffic within the network and respond accordingly.

    How Zero Trust Model Works

    Zero trust security requires setting up and reinforcing multiple layers of security measures. These layers are designed to detect anomalies and malicious activities, both inside and outside the organization’s network infrastructure. Typical security protocols include authentication methods such as multi-factor authentication (MFA), biometrics, federated identity management protocols, and audit logging tools; network segmentation; application whitelisting; encryption; firewalls; intrusion detection systems; data loss prevention solutions; sandboxing techniques; malware detection solutions; endpoint security solutions; and threat intelligence systems. The goal is to provide an environment where every transaction is securely contained within a microsegmented context so that if one layer of defense fails, another will take its place.
