Claim 0:
1. A method to access first system memory, comprising:
retrieving, by one or more processors, first role history information, first current access history information, and first justification history information of users that have access to the first system memory;
generating, by the one or more processors, one or more request clusters based on the first role history information and the first current access history information of the users that have access to the first system memory;
receiving, by the one or more processors, a first request for access to the first system memory from a new user and a first justification for access for the first system memory, the first request comprises first role information of the new user and first current access information of the new user;
determining, by the one or more processors using k-means, density based spatial clustering of applications with noise (DBSCAN), expectation-maximization (EM), gaussian mixture modeling (GMM) algorithms, or combinations thereof, whether the first request is within a request cluster of the one or more request clusters;
when the first request is within the request cluster of the one or more request clusters:
transmitting, by the one or more processors, the first request and the first justification to a first user in a first stage of a first process;
in response to receiving an indication of grant from the first user:
generating, by the one or more processors, a matrix from the first role information of the new user and the first current access information of the new user of the first request;
determining, using a first neural network, whether to grant the first request based on the matrix in a second stage of the first process;
when the first request is granted by the first neural network, determining, using a second neural network and the one or more processors, whether the first justification is similar to the first justification history information of the users that have access to the first system memory beyond a similarity threshold in the second stage of the first process;
when the first justification is similar to the first justification history information of the users that have access to the first system memory beyond the similarity threshold, determining whether the first process comprises one or more additional stages;
when the first process does not comprise the one or more additional stages, transmitting, using the one or more processors, the first request and the first justification to a final user in a final stage of the first process; and
in response to receiving a final indication of grant from the final user, generating and transmitting, using the one or more processors, a grant notification to the new user indicating that the first request for access to the first system memory is granted.
