Which method effectively limits web usage based on specific categories over time?

The method that effectively limits web usage based on specific categories over time is the implementation of a web policy rule quota. This approach allows administrators to define specific usage quotas assigned to users or groups for different web categories. By setting these quotas, an organization can manage and control how much time or data users can spend on particular categories of websites, thereby promoting responsible use of internet resources and aligning with company policies.

Web policy rule quotas can be very effective in environments where various user groups need different levels of web access based on their roles or responsibilities. For example, an organization may want to allow greater web access for certain research teams while limiting distractions for others, such as administrative staff.

Daily usage caps typically impose a limit based on a single day's usage, which does not consider cumulative usage over a longer period. Service-based filtering focuses on restricting access to services rather than monitoring and limiting usage over time based on categories. Session limits pertain more to the number of concurrent sessions a user can have rather than tracking the duration of web usage in categorized areas.

Overall, utilizing a web policy rule quota gives a comprehensive and structured way to manage web usage while aligning with organizational goals.
