I just returned from a weeklong trip to Europe, where I contributed my voice to the wildly successful series of RSA Security Summits. With near unanimity in London and Zurich the audience accepted our premise that as a result of the changing IT landscape – including cloud, mobile, big data, extended workforce, supply chains – and the realities of today’s sophisticated attackers, the approach to security in organizations needs to dramatically change. Furthermore there was also general agreement that today’s preventive security systems, that are largely perimeter and signature-based, no longer provide sufficient defenses, and that to compensate organizations must improve their detective and response focused security controls. This quickly led to the practical and real challenge of how organizations can best make those improvements. How in an environment of fixed security budgets can organizations invest to create or significantly enhance their monitoring and response capabilities?
