Identifying cyber adversary behavior on a computer network is provided. Individual security events are received from multiple threat intelligence data sources. A security incident corresponding to an attack on at least one element of the computer network, the security incident being described by the individual security events received from the multiple threat intelligence data sources, is matched to a defined cyber adversary objective in a structured framework of a plurality of defined cyber adversary objectives and a related technique associated with the defined cyber adversary objective used by a cyber adversary in the attack. A set of mitigation actions is performed on the computer network based on matching the security incident corresponding to the attack on the computer network to the defined cyber adversary objective and the related technique.

Optimizing ingestion of security structured data into a graph database for security analytics is provided. A plurality of streams of information is received from a plurality of security information sources. Respective subsets of information are ingested from each of the plurality of security information sources to generate small subgraphs of security information. Each of the small subgraphs comply to a schema used by a master knowledge graph. A batch process is performed to ingest a plurality of small subgraphs into the master knowledge graph.

Prioritizing security incidents for analysis is provided. A set of security information and event management data corresponding to each of a set of security incidents is retrieved. A source weight of a security incident and a magnitude of the security incident are used to determine a priority of the security incident within the set of security incidents. A local analysis of the security incident is performed based on the retrieved set of security information and event management data corresponding to the security incident and the determined priority of the security incident.
