Abstract
A system and method for content request monitoring and filtering for a plurality of managed devices in a managed network uses a smart PAC file that is uniquely associated with a particular user using a particular managed device and a DNS look up to perform both the logging/monitoring of the content request and the filtering without a hardware appliance or partial proxying.
Claims4
An internal IP address filtering method for a plurality of managed devices on a network of an entity having a private IP address, each managed device having a smart PAC file that is unique to each managed device and a user of the managed device, the smart PAC file having a plurality of lines of instructions that monitor and filter content being requested by the managed device using a filtering policy and a universally unique identifier that uniquely identifies each managed device and the user of the managed device and associates the managed device and the user of the managed device with the filtering policy contained in the smart PAC, the method comprising:
- creating a fused smart PAC, from the smart PAC files for each of the managed devices, the fused smart PAC having a plurality of lines of instructions of a filtering policy for each of the managed devices associated with the private IP address that monitors and filters content being requested by each managed device that is associated with the private IP address;
- communicating the fused smart PAC to a domain name service (DNS) server;
- communicating, by a particular managed device to the DNS server using a DNS protocol, a hostname for each piece of content requested by the particular managed device and the universally unique identifier of the particular managed device;
- and
- monitoring and filtering content requested by the particular managed device using the filtering policy for each of the managed devices associated with the private IP address contained in the fused smart PAC.
A system for internal IP address filtering, comprising:
- a plurality of managed devices in a network of an entity having a private IP address, each managed device having a smart PAC file that is unique to the managed device and a user of the managed device, the smart PAC file having a plurality of lines of instructions that monitor and filter content being requested by the managed device using a filtering policy and a universally unique identifier that uniquely identifies the managed device and the user of the managed device and associates the managed device and the user of the managed device with the filtering policy contained in the smart PAC;
- the entity network further comprising a server configured to create a fused smart PAC, from the smart PAC files for each of the managed devices, the fused smart PAC having a plurality of lines of instructions of a filtering policy for each of the managed devices associated with the private IP address that monitor and filter content being requested by each managed device that is associated with the private IP address;
- the entity network further comprising a domain name service (DNS) server configured to:
- receive the fused smart PAC;
- receive, from a particular managed device using a DNS protocol, a hostname for each piece of content requested by the particular managed device and the universally unique identifier of the particular managed device;
- and
- monitoring and filtering content requested by the particular managed device using the filtering policy for each of the managed devices associated with the private IP address contained in the fused smart PAC.
