What is MMIT cyber security?

Could you please elaborate on what MMIT cyber security entails? Is it a specific technology, a set of protocols, or a methodology employed to safeguard digital assets and networks? I'm particularly interested in understanding its scope, the key principles it adheres to, and any notable successes or challenges it has faced in the realm of cryptocurrency and finance. Additionally, how does MMIT cyber security compare to other established cybersecurity frameworks, and what sets it apart?
