On the technical side, authentication is much the same as it was years ago. But the way consumers are using two-factor authentication products has dramatically changed, says Vasco's Jan Valcke.

When considering security products, companies need to run test scenarios to make certain the product can handle their type of traffic, says Ixia's Richard Favier.

A new study from Neustar shows DDoS attacks in the United Kingdom are often used as a smoke screen for malware attacks or theft, says security specialist Susan Warner.

The key to creating secure applications is choosing the right open source components and carefully monitoring them to ensure they remain free of defects, says Sonatype's Wai Man Yau.

New technology enables organizations to protect applications against reverse engineering and tampering by cybercriminals, says Arxan Technologies' Mark Noctor, who explains how the approach works.

"If you're not doing the right things on managing vulnerabilities, it doesn't really matter what other kinds of sophisticated things you do - that's the baseline for security," says BeyondTrust's Marc Maiffret.

Cloud-based "testing-as-a-service" and "security-as-a-service" platforms can make security more accessible to smaller organizations, says Spirent's Brian Buege.

As cyber-attacks become more common, organizations must devise new ways to shorten response times and lessen the impact, says Paul Nguyen of CSG Invotas.

The best way to detect whether hackers have penetrated an IT system is to examine outbound traffic, says Eric Cole, the latest inductee to the Infosecurity Europe Hall of Fame.

A George Mason University research fellow says the cybersecurity framework, issued earlier this year by the National Institute of Standards and Technology, is likely to cause more problems than it solves.
