Acronym for Security Information and Event Management—centralised security logging and threat detection.
SIEM stands for Security Information and Event Management. See 'Security Information and Event Management' for the full definition. UK organisations in regulated industries often require UK-based SIEM solutions like Assuria to meet data residency requirements.
Why It Matters
The DSC Perspective:
SIEM is a cornerstone of compliance evidence. When auditors ask how you monitor for security incidents or how long you retain logs, SIEM is typically the answer. Defence sector organisations often require UK-hosted SIEM specifically.
