Cybersecurity Emerges as a Big Data Problem
In a connected world there are no boundaries. Desk-bound activities such as email are now performed on mobile devices. What once required a personal visit is now be done online (e.g. banking, shopping) – from anywhere, anytime. Access, convenience and speed have created remarkable change in the way we consume and interact. The march to connected-digital is accelerating with our growing dependence. But digital interconnectedness is not for free. Risks of security breaches, data loss, espionage, denial of service, malware, and even more through cyber attacks are both numerous and growing.
Over the past few years, businesses have deployed various kinds of security appliances in their data centers to protect against pointed threats, such as intrusions, denials of service, viruses, spam, data loss, compliance and so forth. Appliances provide real-time, in-stream filtering, detection and prevention capabilities, and have proven to be very useful and cost effective protection against isolated threats.
Security appliances are a growing market with many choices, and vendors are rapidly adding new functionality to strengthen in-stream capabilities. It is not unusual for a typical company to have dozens of these appliances in their data center. However, there are some limitations. As security appliances mature so do cyber criminals. Cyberattacks are becoming more sophisticated with more coordination, deft and reach to circumvent security appliances. One of the vulnerabilities is that appliances are “point solutions” - meaning each appliance is only aware of what it sees and has no visibility to traffic elsewhere. Cybercriminals can quite easily exploit these limitations to wreak havoc.
