A computer system, device, computer software, and/or method performed by a computer system, is provided for determining a user name likely to be associated with an attack, a configuration, or a vulnerability. First data is obtained which associates user names with individual IP addresses onto which the user names were logged in. Second data is obtained which associates attacks, configurations, or vulnerabilities with individual IP addresses on which the attacks occurred or on which the configurations or vulnerabilities exist. The user names from the first data are associated with the attacks, configurations or vulnerabilities from the second data based on having the same IP address during a log-in. An individual user name is indicated as being associated with attacks which occurred while the individual user name was logged in or with configurations or vulnerabilities for an IP address onto which the user logs in.

Real-time user awareness for a computer network

A policy component includes policy configuration information. The policy configuration information contains one or more rules. Each rule and group of rules can be associated with a set of response actions. As the nodes on the monitored networks change or intrusive actions are introduced on the networks, network change events or intrusion events are generated. The policy component correlates network change events and/or intrusions events with network map information. The network map contains information on the network topology, services and network devices, amongst other things. When certain criteria is satisfied based on the correlation, a policy violation event may be issued by the system resulting in alerts or remediations.
