What is the primary function of the User-ID agent?

The primary function of the User-ID agent is to map IP addresses to user identities. This capability is essential for enhancing security within a network. By associating users with their respective IP addresses, the User-ID agent enables firewall policies to be applied based on user identities rather than just IP addresses. This mapping allows for more granular control over access and permissions, making it easier to implement security policies that reflect user roles and functions within an organization.

Incorporating User-ID into network security strategies helps organizations effectively monitor and manage user activity, ensuring that the right users have the right access to resources. This also aids in compliance and reporting, as activities can be tied back to specific user identities rather than being solely based on potentially dynamic IP addresses.
