However, being an able security administrator does not mean you are necessarily skilled at probing for holes in the solutions you control. Penetration testing can be automated through software, but that can lack the ingenuity of a live human trying to breach your system. The value in skilled ethical hacking is tremendous and critical for identifying vulnerability in cybersecurity solutions before a real bad actor comes along. The United States Air Force has used ethical hacking to simulate a user with insider access gone rogue , for example, and DARPA has hosted ethical hacking tournaments to develop AI cybersecurity tools like Mayhem , which can identify and fix vulnerabilities with minimal human involvement.

The information that goes into an AI cybersecurity tool is arguably just as critical as the tool itself. For instance, AI-powered network traffic analysis NTA tools function by learning what is normal in a network and then flagging what is anomalous, or abnormal.

The AI can learn by itself over time unsupervised machine learning , learn by being fed a set of pre-determined parameters, like a list of known viruses and what they look like and how they behave supervised machine learning , or both. The more data, and the wider the variety of data, you give an AI-powered cybersecurity solution, the better.

Of course, not everything abnormal is an attack, and AI-driven tools that are operating under limited data — for instance, only considering an analysis of network traffic without knowing typical threat behaviors — may trigger false positives from benign actions. Training AI on what an actual attack might look like helps it distinguish between harmless abnormal behavior and malicious anomalies. AI-powered cybersecurity tools are very good at recognizing the work of software because malware will usually behave in predetermined or recognizable patterns.

An actual human who has penetrated a system, though, may not be so predictable. What steps is this malicious actor taking? Where do they look first, once they have breached the perimeter defenses and gained access?

Ethical hackers can also try to leverage human error in the way a real black-hat hacker might. They can use business email compromise BEC scam or compromised websites, or see how your employees might respond to a phishing attack. Skilled white-hat hackers can help identify vulnerability in cybersecurity protocol in two ways: They can show security professionals where their human-error-driven weak points are, so they can modify or increase training, and they can teach an AI-based system what it looks like when the first lines of defense have failed.
