Artificial Intelligence (AI) refers to computer programs designed to perform tasks that typically require human intelligence. These include learning, problem-solving, decision-making, and perception. AI systems use big data and algorithms to analyze information, adapt their behavior, and achieve goals without constant human oversight.
The rapid improvements in AI capabilities enable advanced attacks by malicious actors. Attackers no longer rely solely on manual intrusion attempts. They harness automation, AI-driven malware, and Living off the Land (LOTL) tactics that blend with legitimate activity. Organizations must adopt equally advanced technologies to defend against this new threat landscape.
In modern security operations, AI is indispensable. It applies not only to anomaly detection but also to log correlation, malware classification, phishing detection, and threat intelligence. The key advantage lies in speed and scale. AI can process millions of events across distributed environments and highlight suspicious activity in minutes, something human analysts could never achieve.
Challenges with traditional detection methods
Traditional detection methods are effective against known threats but often struggle with scale and adaptability. Security teams face these challenges:
Alert fatigue: Security Operations Centers (SOCs) often drown in thousands of daily alerts. Most are false positives or low priority, but analysts must review them. The repetitive nature of this work creates alert fatigue, where genuine threats are overlooked or not properly treated due to the overwhelming noise. This directly contributes to analyst burnout and increases Mean Time to Detect (MTTD).

This directly contributes to analyst burnout and increases Mean Time to Detect (MTTD). Rapid exploitation of vulnerabilities: When new vulnerabilities are disclosed, threat actors can weaponize them within days or even hours. Proof of Concept (PoC) exploits are quickly shared across forums and integrated into botnets or ransomware kits. Organizations relying on manual patch cycles or traditional vulnerability scanners are left exposed, often for weeks. This gives attackers a significant advantage.

Evasion through legitimate processes: Modern adversaries increasingly hide their activity by leveraging existing tools and methods in the target environment. This includes Living off the Land (LOTL) techniques such as abusing and exploiting trusted applications, system services, or even security tools to mask malicious behavior. Because these processes are also used daily by administrators and business applications, distinguishing between routine operations and malicious use is highly challenging. As a result, signature-based defenses often fail.

Even with powerful indexing and search engines, correlating this data in real-time is nearly impossible with static rule sets. This data overload leads to blind spots where attackers can hide.

Advanced phishing campaigns: Phishing remains the most common initial attack vector for malware and credential theft. With generative AI, adversaries craft compelling emails free of grammatical errors and inconsistencies. To the human eye, these attacks are nearly indistinguishable from genuine communications.
