Zero trust is a security concept that suggests that organizations should not trust any users, devices, or networks within or outside of their perimeter. Instead, all access to resources should be based on verifying the identity of the user or device and ensuring that they meet the necessary security policies.
Here are some key principles of zero trust:
Verify before granting access: Before granting access to resources, verify the identity of the user or device and ensure that they meet the necessary security policies.
Micro-segmentation: Divide your network into small segments, and apply security controls at each segment. This makes it harder for attackers to move laterally within your network.
Least privilege: Grant users and devices the minimum level of access necessary to perform their duties. This reduces the risk of unauthorized access to sensitive resources.
Continuous monitoring: Monitor your network and devices continuously to detect and respond to threats in real-time.
Multi-factor authentication: Use multiple methods to verify the identity of users, such as passwords, biometrics, or security tokens.
By implementing these principles, organizations can significantly improve their security posture and reduce the risk of cyber attacks.
