Zero trust is a security concept that assumes that no network or system can be fully trusted, and all access to resources should be granted on a case-by-case basis. The goal of zero trust is to reduce the attack surface of a network by limiting access to only those resources that are necessary for a specific task.
To implement zero trust, there are several solutions that can be used:
- Identity and access management (IAM) solutions: These solutions help to verify the identity of users and devices before granting access to resources. They can use methods such as multi-factor authentication (MFA) and certificate-based authentication to verify identities.
- Network segmentation: This involves dividing a network into smaller segments, each with its own security controls, to limit the impact of a compromise.
- Microsegmentation: This involves dividing a network into even smaller segments, down to the level of individual resources or applications. This allows for more granular control over access to resources.
- Endpoint security: This involves protecting endpoint devices, such as laptops and smartphones, from threats by using solutions such as antivirus software and firewalls.
- Cloud security: For organizations using cloud resources, implementing security measures such as encryption, access controls, and monitoring can help to secure data and resources in the cloud.
