METHOD, SYSTEM, AND COMPUTER PROGRAM PRODUCT FOR CONTROLLING ACCESS IN A NETWORK OF SERVERS

Abstract:

Provided is a method for controlling access in a network of servers, which may include generating a set of nodes including a node for each account of each server. For each respective node, at least one other node of the set of nodes having credential-free access to the respective node may be determined. For each respective node, an edge connecting the respective node to each of the other node(s) of the set of nodes having credential-free access may be generated. The set of nodes and edges may collectively define a graph. For at least a first node, second nodes of the set of nodes that have indirect access to the first node(s) via at least one of the other node(s) having credential-free access to the first node(s) may be determined based on the graph. A system and computer program product are also disclosed.
