A policy scheduler is a feature that allows a security policy to be activated or deactivated for a specified time period. You can define schedulers for a single or recurrent time slot within which a policy is active. Two statements that are correct about a policy scheduler are:
A policy scheduler can be defined using a daily schedule: You can configure a scheduler to be active every day for a certain time interval, such as from 8:00 AM to 5:00 PM. You can also exclude specific days from the daily schedule, such as weekends or holidays.
A policy scheduler determines the time frame that a security policy is actively evaluated: When you associate a scheduler with a security policy, the policy is only available for policy lookup during the time frame specified by the scheduler. When the scheduler is off, the policy is inactive and cannot be matched by any traffic.

Adaptive Threat Profiling (ATP) is a Juniper Networks solution that enables organizations to detect malicious activity on their networks and process it through IPS and Juniper ATP Cloud for malware and virus protection. ATP is powered by Juniper's advanced Machine Learning and Artificial Intelligence (AI) capabilities, allowing it to detect and block malicious activity in real-time. ATP is integrated with Juniper's Unified Threat Management (UTM) and Encrypted Traffic Insights (ETI) solutions, providing an end-to-end network protection solution.
