RPC port mapper integrity checker to improve security of a provisionable network

In a network comprising a plurality of network port connections, a network port map verification tool, comprising:

• a port assignment file, stored in an electronic device, comprising a port authorization, which includes an authorized port of an authorized service, in said network;
• and
• a port assignment file verifier wherein said verifier is enabled to verify a port assignment against said port authorization by,
• querying a port mapper for a mapped port assignment, which was created when an application registered a service provided by the application with said port mapper at the time said application was brought up, said mapped port assignment includes a current port used by said registered service;
• determining if an identified service is currently using said authorized port by comparing said mapped port assignment to said port authorization;
• and
• initiating a response to said comparing.

A system for protecting network security, comprising:

• a network server coupled to a network;
• a network client communicatively coupled with said network server via a port;
• a plurality of provisionable services enabled to communicate with said server via a plurality of ports;
• and
• a port map verification tool enabled to compare a port assignment to a port authorization, which includes an authorized port of an authorized service, in said network by,
• querying a port mapper for a mapped port assignment, which was created when an application registered a service provided by the application with said port mapper at the time said application was brought up, said mapped port assignment includes a current port used by said registered service;
• determining if an identified service is currently using said authorized port by comparing said mapped port assignment to said port authorization;
• and
