## Description

The Combined Authority require security events, that are captured and correlated by the SIEM solution, to be monitored 24/7 using an externally hosted Security Operations Centre (SOC).  The Combined Authority will leverage the security alerts provided by the SOC: • To understand where the Combined Authority needs to focus its resources to maximise its cybersecurity posture. • To detect and respond to threats, keeping the information held on systems and networks secure. • To increase resilience by learning about the changing threat landscape (both malicious and non-malicious, internal and external). • To identify and address negligent or criminal behaviours. • To derive business intelligence about user’s behaviours to shape and prioritise the development of technologies.
