Kas saaksite selgitada nulli usaldus poliitika kontseptsiooni ja kuidas seda rakendatakse infotehnoloogias?

Zero Trust policy is an information security concept according to which no user or device is automatically considered trustworthy, even if they are within the corporate network.

Core principles:

• Verification of each request: access is granted only after strict authentication and authorization.
• Minimal access rights: users and services receive only the rights necessary for their work.
• Network microsegmentation: dividing the network into isolated zones to limit the spread of threats.
• Continuous monitoring and analysis: tracking activity to detect anomalies.

Implementation includes:

• Use of multi-factor authentication (MFA).
• Access control based on roles and policies.
• Encryption of data in transit and at rest.
• Use of intrusion detection and behavioral analysis systems.

Example: an employee attempts to access an internal application — the system requires identity confirmation, checks the device according to security policy, and grants access only to the necessary resources, not to the entire network.
