摘要：Heuristics-based anti-phishing systems are the most deployed solutions in cyberspace. This is due to their generalization feature which is capable of preventing zero-day attacks. However, this promising anti-phishing countermeasure is faced with the problem of managing the feature corpus for scale and complexity. In addition, managing the redundant feature during an upgrade is another factor. In this paper, an incremental component system is proposed to this problem. The proposed framework consists of atomic units and composite units. These units provide encapsulations through which feature corpus is built with ease of management and upgrade. The scheme provides both generic and specific frameworks for designing an anti-phishing scheme with effective management of feature vectors. Therefore, maintenance and updates can be integrated without the total collapse of the system. Hence, the proposed framework can be described as being fault tolerant.
