Zero trust is a cybersecurity approach that assumes that all network traffic and users, whether internal or external, are potentially untrusted and must be verified before being granted access to resources. This approach is based on the premise that traditional security approaches, which rely on perimeter-based security controls to protect networks, are no longer sufficient to protect against modern cyber threats.
There are several types of zero trust models that organizations can implement, including:
Network segmentation: This involves dividing a network into smaller, more secure segments, with strict controls in place to prevent unauthorized access between segments. This can help to limit the spread of malware or other threats within the network.
Microsegmentation: This involves segmenting networks at a much finer level, with each individual device or resource being placed in its own segment. This can help to further limit the spread of threats within the network.
Zero trust network access (ZTNA): This involves implementing strict controls on network access, requiring users to authenticate and authorize themselves before being granted access to resources. This can help to prevent unauthorized access to the network.
Zero trust platform (ZTP): This involves implementing zero trust principles across an entire organization, including both network and application-level security controls. This can help to ensure that all resources and systems are protected against cyber threats.
Overall, zero trust is a cybersecurity approach that assumes that all network traffic and users are potentially untrusted and must be verified before being granted access to resources. There are several types of zero trust models that organizations can impl
