The Bank of England (BoE) has evolved from a reactive SOC, very much focused on ‘known threats’, to a proactive SOC, shifting the focus towards hunting down and responding to "unknown' threats. BoE also recognised the need to implement a new operating model to realise this strategy shift; one where the technology fits the operating model and not the other way around. This session will cover how BoE developed the strategy to become proactive, put the people/process/technology mix together, how data analytics helped develop a continual threat hunting capability and the ways BoE are profiling adversary techniques to proactively hunt adversaries and protect £637 billion in daily transactions.
