Despite the growing awareness of cyber-attacks and the increasingly sophisticated tools and technologies available to combat data breaches, the problem is getting worse. What’s more, organizations face steep challenges in dealing with cyber-attacks, and many are underreporting incidents, according to a recently released research report from ThreatTrack. The company polled 200 security professionals in U.S. enterprises and found that 57 percent had experienced a data breach that they did not disclose. Moreover, 72 percent said that addressing malware is equally or more difficult this year than it was last year. Part of the problem is that the nature of data breaches is growing more diverse and affecting firms on a wider scale. As a result, enterprises are struggling to keep up.
