Zero trust is a security stance for networking based on not trusting any users, devices, or applications by default, even those that are already on the network.The zero trust model uses identity and access management (IAM) as a foundation for an organization’s security program.For this assignment:
Research the zero trust model.
Write a report that describes the following:
The purpose of zero trust and what differentiates it from other security models
An overview of how zero trust works in a network environment
How zero trust incorporates least privilege access through role-based access control (RBAC) and/or attribute-based access control (ABAC)
Full Answer Section
How Zero Trust Works
Zero trust works by implementing a number of security controls, such as:
- Identity and access management (IAM): This is used to identify and authenticate users and devices.
- Micro-segmentation: This is used to divide the network into smaller segments, each with its own security controls.
- Continuous monitoring: This is used to monitor the network for suspicious activity.
- Threat intelligence: This is used to identify and track threats.
These security controls work together to create a layered defense that makes it more difficult for attackers to gain access to sensitive data.
How Zero Trust Incorporates Least Privilege Access
Zero trust incorporates least privilege access through role-based access control (RBAC) and/or attribute-based access control (ABAC). RBAC is a method of granting permissions based on a user's role in the organization. ABAC is a more granular method of granting permissions based on a user's attributes, such as their department, their location, or the device they are using.
By using least privilege access, zero trust helps to reduce the attack surface and makes it more difficult for attackers to gain access to sensitive data.
Benefits of Zero Trust
The benefits of zero trust include:
- Increased security: Zero trust helps to protect an organization's data and systems from unauthorized access.
- Reduced risk: Zero trust helps to reduce the risk of data breaches and other security incidents.
- Increased efficiency: Zero trust can help to improve operational efficiency by reducing the need for manual security tasks.
- Improved compliance: Zero trust can help organizations to comply with security regulations.
Challenges of Zero Trust
The challenges of zero trust include:
- Complexity: Zero trust can be a complex security model to implement and manage.
- Cost: Zero trust can be a costly security model to implement.
- Training: Employees may need training on how to use zero trust security controls.
Conclusion
Zero trust is a security model that is gaining popularity due to its ability to protect organizations from unauthorized access. However, it is important to note that zero trust is not a silver bullet and it should be implemented as part of a comprehensive security strategy.
Sample Answer
Purpose of Zero Trust
The purpose of zero trust is to protect an organization's data and systems from unauthorized access. It does this by assuming that no user or device is trusted by default, even if they are already on the network. This is in contrast to traditional security models, which typically trust users and devices once they have been authenticated.
Zero trust is based on the principle of least privilege, which means that users and devices should only be granted the permissions they need to do their jobs. This helps to reduce the attack surface and makes it more difficult for attackers to gain access to sensitive data.
