Abstract

The complexity and ongoing evolution of Advanced Persistent Threats (APTs) compromise the efficacy of conventional cybersecurity measures. Firewalls, intrusion detection systems, and antivirus software, which are dependent on static rules and predefined signatures, are increasingly ineffective against these sophisticated threats. Moreover, the use of system audit logs for threat hunting involves a retrospective review of cybersecurity incidents to reconstruct attack paths for attribution, which affects the timeliness and effectiveness of threat detection and response. Even when the attacker is identified, this method does not prevent cyber attacks. To address these challenges, we introduce ThreatInsight, a novel early-stage threat detection solution that minimizes reliance on system audit logs. ThreatInsight detects potential threats by analyzing IPs captured from HoneyPoints. These IPs are processed through threat data mining and threat feature modeling. By employing fact-based and semantic reasoning techniques based on the APT Threat Intelligence Knowledge Graph (APT-TI-KG), ThreatInsight identifies and attributes attackers. The system generates analysis reports detailing the threat knowledge concerning IPs and attributed attackers, equipping analysts with actionable insights and defense strategies. The system architecture includes modules for HoneyPoint IP extraction, Threat Intelligence (TI) data analysis, attacker attribution, and analysis report generation. ThreatInsight facilitates real-time analysis and the identification of potential threats at early stages, thereby enhancing the early detection capabilities of cybersecurity defense systems and improving overall threat detection and proactive defense effectiveness.
