Abstract

The financial sector faces an increasingly sophisticated threat landscape characterized by advanced persistent threats, organized cybercrime, and nation-state actors targeting critical financial infrastructure. Traditional network security monitoring approaches have proven inadequate against these evolving threats due to their reactive nature and inability to correlate complex attack patterns across distributed financial systems. Financial institutions require specialized security monitoring frameworks that account for their unique operational characteristics, including high-volume transaction processing, regulatory compliance requirements, and the critical need for system availability. This paper addresses the fundamental limitations of conventional security monitoring in financial contexts by proposing a comprehensive systematic framework that integrates multiple detection methodologies within a unified architecture. The approach recognizes that financial cyberattacks often manifest as coordinated campaigns across multiple vectors, requiring security systems capable of detecting subtle anomalies and establishing relationships between seemingly unrelated events.
