Almost every cybersecurity expert acknowledges the end of the era of prevention-only InfoSec. While a strong digital perimeter remains an essential cybersecurity feature, it can’t stop every evolved penetrative cyber attack. Without some kind of analytical component to your cybersecurity, hackers could easily gain the upper hand.
Therefore, next-generation security analytics must form the linchpin of your next-gen cybersecurity strategy. But why? What does modern security analytics offer your business’ InfoSec?
We explore a few next-gen security analytics essential capabilities below.
Continuous Threat Intelligence
Ideally, your cybersecurity solution should provide your IT security team with up-to-date threat intelligence. Every business, including yours, faces distinct cybersecurity threats, based on their industry-vertical and size. Therefore, you need to properly prepare your IT environment against those threats in particular—impossible without the right knowledge.
Your security analytics should provide your enterprise with continuous threat intelligence, optimally from multiple feeds and sources. In fact, without good threat intelligence, you can’t expect optimal performance from your security analytics.
Threat intelligence and security analytics work in a symbiotic relationship. Your security analytics can’t hunt for threats without intelligence; conversely, threat intelligence without analytics to utilize it can’t protect your digital assets.
Facilitated Threat Hunting
Next-generation security analytics actually helps pave the wave for effective and proactive threat hunting. Threat hunting allows your IT security team to pursue cyber attackers throughout the network.
Granted, your enterprise should have a dedicated threat hunting team which can search for penetrative cyber attacks without indicators. They can utilize their familiarity and experience with the environment to get an advantage on hackers.
However, your threat hunters can use alerts generated by your next-generation security analytics to find threats even faster. Security analytics can process the log data and activity events from throughout your network, and correlate it to find potential breaches. Then it generates an alert with context for possible investigation and sends it to the team. With this information in hand, hunters may catch the scent of their prey even faster than before.
Improved Network Visibility
Network visibility forms such an essential part of modern cybersecurity, no InfoSec article could possibly overstate its importance. As your IT environment scales, it incorporates more databases, digital assets, applications, users, and potentially locations (such as cloud servers). Each addition creates the possibility of an area going “dark” or becoming invisible to legacy detection capabilities.
Often, hackers can find and exploit these dark areas in your enterprise network. After all, these digital shadows create opportunities for concealed lateral movements, island hopping attacks, or implanted dwelling threats.
In addition, without proper visibility into your IT environment, you won’t know the full extent of what you must protect. Cases exist in which enterprise lost track of critical databases until after a hacker infiltrated it.
Next-generation security analytics solves this issue by improving visibility into the IT environment. It can uncover previously concealed databases and follow security correlations to detect dwelling threats.
Visualization and Machine Learning
Machine learning can significantly reduce the burden on your IT security team by automating security workflows, detection, and correlation. While it does require regular evaluation and maintenance for optimal performance, it can provide much of contextualization and investigation legwork automatically. This can help your team determine whether the alert is, in fact, a true threat indicator or whether it only demonstrates a false positive.
Next-generation security analytics, in particular, can offer graph analytics and visualization to help your team better understand its threat vulnerabilities and determine potential threats. Sometimes, having the image on the screen can make a difference.
