1. A method, comprising:

  • monitoring votes from a plurality of nodes for node categorization;

    identifying a pattern associated with the votes;

    identifying undesirable nodes based on the pattern associated with the votes, wherein the node categorization includes identifying at least some of the undesirable nodes as malicious nodes being associated with propagation of malware, and wherein the malicious nodes are provided on a black list; and

    implementing a policy at a firewall that precludes communication with the malicious nodes provided on the black list and that withdrawals data access rights for the malicious nodes provided on the black list, wherein a network is partitioned for the malicious nodes based on the pattern, and wherein partitions that include the malicious nodes are refined over iterations of subsequent voting sessions involving the plurality of nodes.
