In the past year, we have witnessed a dramatic rise in the number of platforms and apps based on machine learning and artificial intelligence. AI technology has impacted from software and the Internet industry to other verticals such as healthcare, legal, manufacturing, automobile and agriculture. This trend has also applied to security industry, with all types of security products (e.g. malware detection engines, firewall IPS/IDS engines and endpoint sandboxes) beginning to leverage AI technology to escalate their power for better detection rates and quicker response speeds. However, at the same time, due to the increasingly complex model, especially in some deep neural network-based engines, it is extremely hard to understand the decision made by the products. Typical concerns include reactions such as "How on earth did the endpoint product quarantine my document?" from a frustrated customer, and complaint such as "How did the firewall miss such a native C&C traffic?" from a Dev-Ops team. As a result, an accountable explanation is becoming a necessary part along with the "binary" malicious-or-benign result.

In this talk, we want to ask questions of these AI-powered products: Why does this SVM-based scanner report certain binary files as malware? What caused the RNN-based firewall to reset the traffic to this IP address? With the emerging of XAI (eXplainable AI), we are able to peek inside the complicated machine learning "Black-Box". The core part of this talk is to demonstrate how to explain the result from AI-powered security products and what kind of answers we can get from them. A further investigation is "is the answer convincible and constructive?".

With concrete examples shown in the talk, we expect to make the audience aware of the importance of XAI to the current security industry, and to revisit existing products to check whether the current model is really effective or whether it happened to be a "happy accident".
