Further, it's becoming increasingly clear that observing user behavior is an insightful way to pinpoint potentially malicious activity, including the often-missed reconnaissance phases of an attack. We need to take note that some of these systems can process millions of data points per second, a rate that surpasses legacy methods.
Instead of fixed thresholds, the adoption of dynamic baselines based on user behavior is a more robust approach, as it readily adapts to shifting patterns of activity. It's important to understand that the AI behind these detection systems utilizes data from numerous sources to achieve a broader context of any threats. The ability to understand the "where", "when", and "who" related to an attack is incredibly valuable, though unfortunately these systems aren't perfect and can produce many false positive alerts.
In the hunt for compromises, systems are moving away from simply relying on indicators of compromise (IOCs) associated with known malware to evaluating the behaviors observed. This behavioral analysis approach is particularly beneficial in identifying zero-day attacks that have no known signatures. One noticeable difference between behavioral analysis and static code analysis is that behavioral analysis looks at what the code is actually doing, not just the code itself. This is an advantage in identifying hidden threats.
However, even in 2024 these systems are still not without challenges. One major hurdle is scalability in very large and complex networks. The sheer volume of data produced in some environments can overwhelm the computational resources and necessitate ongoing innovations in the algorithms to improve efficiency. As the field moves forward, these are the issues researchers will need to overcome if the promise of real-time behavioral analysis is to be fully realized.
