As Singapore accelerates its push to becoming the world's first Smart Nation, seamlessly connecting and enhancing every aspect of the country's infrastructure, cyber security becomes a key contributor to economic growth.
A recent survey by the Economist Intelligence Unit (EIU) revealed that more than one-fifth businesses across the Asia Pacific Japan (APJ) expect to be hit by a serious cyber-attack within the next 90 days. We now live in a world where the question for cybersecurity is no longer 'what ifs' but 'when' we will be attacked.
Not just about security, but resilience
Today's threats continue to increase in volume, veracity and variety. With the widespread adoption of cloud and mobile in the enterprise, applications and user data are stored and exchanged on more devices and locations than before. Cyber-attackers are becoming more creative and successful in attempts to access via numerous potential entry points.
Taking a leaf from Sun Tzu's when facing adversaries: Organizations must assume they will face a serious cyber-attack and align their security strategy to be resilient rather than reactive.
The approach of cyber security resilience negates this. Resilience is the ability to recover quickly from difficulties and in this case, cyber resilience requires businesses to develop a plan to identify, prevent, detect, respond and recover from cyber-attacks, minimizing customer harm, reputational damage and financial loss.
Vulnerabilities are becoming more sophisticated where it is now easier for compromises to spread across the network. Sustained economic growth demands that businesses think beyond information security to network resilience.
Virtualization transforms security, enabling resilience from inside-out
Conventional firewall-based security sits at the perimeter of the network is not robust enough. In fact, an astounding number of more than 70% of successful cyber attackers gain insider access through lost, stolen or weak credentials.
Businesses need a ubiquitous architectural plan that cuts across compute, network, storage and clouds to seamlessly prevent, detect and respond to cyber-attacks taking advantage of new gaps or exposed frontiers.
Traditionally, perimeter-centric security models govern most data centers, and if the perimeter is breached, there are no internal controls to prevent lateral attacks. An approach called micro-segmentation limits the spread of attacks inside the data center, but until recently, it was cost-prohibitive and operationally infeasible. Micro-segmentation, powered by network virtualization, not only adopts such an approach, but also delivers the operational agility of network virtualization that is the foundation of a modern digital business.
