Without covering the basics, there isn’t much point in having a SIEM. Harden your environment and configure appropriate auditing on all endpoints.
A Detection and Complianace Matrix is an object oriented, relational database approach to recording and associating all elements to one another - cases, adversaries, techniques, mitigations, detections, hunts, log sources, etc.
Detection Tactics To detect an attacker, one must be equipped with the necessary logs to reveal their activities. Here we use a matrix to map detection tactics to attacker tactics (Mitre ATT&CK).
Detection Methods Once necessary logs are collected (detection tactics), use various methods to reveal anomalous, suspicious, and malicious activity.
Playbooks Playbooks provide a means to document solutions for many reasons including tracking work, uniform response, content recreation, metrics & reporting, making informed decisions, avoiding work duplication, and more.
These efforts can provide significant benefits to some ingested logs. Typically enrichment will result in either adding a new field to events or a lookup table for use in filtering or filling in a field.
Set up a lab with a Windows system, a SIEM, and an attacking system to aid in detection research and development.
