Security Analytics: CXOs' Key To Breach Detection

While most companies are spending considerably on information security, the number of security breaches at major organizations are also rising at the same time. A Gartner report states that as the impact of advanced attacks has reached boardroom-level attention, many organizations are looking at security analytics as a discipline to better fight against such attacks.

“Breach detection is top of mind for security buyers and the field of security technologies claiming to find breaches or detect advanced attacks is at an all-time noise level,” said Eric Ahlm, research director at Gartner. “Security analytics platforms endeavor to bring situational awareness to security events by gathering and analyzing a broader set of data, such that the events that pose the greatest harm to an organization are found and prioritized with greater accuracy.”

When it comes to gathering masses of security data that can be analyzed to bring greater meaning to security events, security information and event management (SIEM) technologies are topping the list of likely solutions. While most SIEM products have the ability to collect, store and analyze security data, the meaning that can be pulled from a data store (such as the security data found in a SIEM) depends on how the data is reviewed. How well a SIEM product can perform automated analytics — compared with user queries and rules — has become an area of differentiation among SIEM providers, says Gartner.

User behavior analytics (UBA) is another example of security analytics that is already gaining buyer attention. UBA allows user activity to be analyzed, much in the same way a fraud detection system would monitor a user’s credit cards for theft. UBA systems are effective at detecting meaningful security events, such as a compromised user account and rogue insiders. Although many UBA systems can analyze more data than just user profiles, such as devices and geo-locations, there is still an opportunity to enhance the analytics to include even more data points that can increase the accuracy of detecting a breach.

“Today, there are certainly commercially viable applications of analytics to better position security technologies, such as with SIEM and UBA providers,” said Ahlm. “However, the applications or other problems that can be addressed for other security markets are still emerging and on the whole, the security industry is rather immature in the application of analytics.”

As security analytics platforms grow in maturity and accuracy, a driving factor for their innovation is how much data can be brought into the analysis. Today, information about hosts, networks, users and external actors is the most common data brought into an analysis. However, the amount of context that can be brought into an analysis is truly boundless and presents an opportunity for owners of interesting data and the security providers looking to increase their effectiveness.

“Ultimately, how actual human users interface with the outputs of large data analytics will greatly determine if the technology is adopted or deemed to produce useful information in a reasonable amount of time,” said Ahlm. “Like other disciplines that have leveraged large data analytics to discover new things or produce new outputs, visualization of that data will greatly affect adoption of the technology.”
