Big Data to drive massive overhaul in security practices in next 24 months

 

That’s the word from RSA, which predicts in a report on Big Data that we will see a market-changing impact on most product categories in the information security sector by 2015, including SIEM, network monitoring, user authentication and authorization, identity management, fraud detection, governance, risk and compliance systems.

One of the largest shifts in the market will be the availability of commercial, off-the-shelf Big Data solutions to support security operations. “Previously, the advanced data analytics tools deployed within security operations centers were custom-built, but 2013 marks the beginning of the commercialization of Big Data technologies in security, a trend that will reshape security approaches, solutions, and spending over the coming years,” RSA said in a briefing emailed to Infosecurity.

Longer term, Big Data will also change the nature of established security approaches. In the next three to five years, data analytics tools will further evolve to enable a range of advanced predictive capabilities and automated real-time controls.

“Big Data is changing the nature and addressing the limitations of conventional security controls such as signature-based anti-malware and firewalls as well as rules-based identity and access management tools,” said Sam Curry, CTO for Identity and Data Protection and chief technologist at RSA. “Big Data is being applied in new ways to enable security controls that are adaptive, risk-based and self-learning so that security is continuously evaluated and the level of protection is automatically adjusted based on changing environmental and risk conditions.”

The rise of a cloud-based, highly mobile business world has rendered obsolete prevailing security practices reliant on perimeter defenses and on static security controls requiring predetermined knowledge of threats. Security leaders are shifting to an intelligence-driven security model – a model that is risk-aware, contextual and agile and can help organizations defend against unknown threats, researchers said.

“In the coming year, top-tier enterprises with progressive security capabilities will adopt intelligence-driven security models based on Big Data analytics,” said Eddie Schwartz, CISO at RSA. “Over the next two to three years, this security model will become a way of life.”

“The discovery of and response to threats and fraud therefore can become more predictive as a richer view of user identities and complex data flows comes together to give a data-driven perspective of what normal versus aberrant behavior looks like,” added Curry.

RSA recommends a handful of best practices to prepare for this sea change. For one, organizations should align their security capabilities behind a holistic cybersecurity strategy and program that is customized for the organization’s specific risks, threats and requirements.

Then they should establish a shared data architecture for security information. Because Big Data analytics require information to be collected from various sources in many different formats, a single architecture that allows all information to be captured, indexed, normalized, analyzed and shared is a logical goal.

Organizations also need to think strategically about which security products they will continue to support and use over several years, because each product will introduce its own data structure that must be integrated into a unified analytics framework for security. At the same time, they should ensure that ongoing investments in security products favor technologies using agile analytics-based approaches, not static tools based on threat signatures or network boundaries. New, Big Data-ready tools should offer the architectural flexibility to change as the business, IT or threat landscape evolves, RSA cautioned.

Personnel is a concern as well. While emerging security solutions will be Big Data ready, security teams may not be. Data analytics is an area where on-staff talent is lacking. Data scientists with specialized knowledge in security are scarce, and they will remain in high demand. As a result, many organizations are likely turn to outside partners to supplement internal security analytics capabilities. And, it’s important to augment internal security analytics programs with external threat intelligence services and evaluate threat data from trustworthy and relevant sources.

“The game is changing,” said William Stewart, senior vice president at Booz Allen Hamilton, a national defense contractor. “More and more data is going onto the internet in automated forms, and that vector will continue. Therefore, a security analysis tool that worked great two or three years ago doesn’t work so well anymore. You now have to look through a whole lot more data, and you have to look for threats that are far more subtle. Commercial tools are changing to take advantage of these Big Data streams coming online.”
