Special Issue Information

Dear Colleagues,

The purpose of this Special Issue is to present up-to-date technologies and research that enable us to maintain network security via network intrusion detection. According to the Google Transparency Report, 99% of Internet traffic is encrypted. Data traffic encryption is one of the most promising ways of protecting users’ privacy. However, it makes us face many new challenges in network-based security controls such as intrusion detection/prevention systems. One of the biggest challenges is that the conventional signature-based detection mechanism does not work over encrypted data traffic. Various alternative approaches have been proposed that use advanced cryptographic technologies and Artificial Intelligence and Machine Learning (AI/ML) techniques. The advancement in these techniques enables network-based security controls to detect anomalies from encrypted data using signature-based detection mechanisms or heuristics such as behavior analysis. We also aim to seek solutions to various network settings from heterogeneous IoT networks to cloud computing. The topic of this Special Issue includes advanced techniques that can contribute to network intrusion or anomaly detection in the modern Internet environment. They include, but are not limited to, the following:

  • Innovative network security architectures for intrusion detection;
  • Intrusion detection on heterogeneous IoT networks;
  • Fog/edge/cloud computing security;
  • AI/ML techniques for anomaly detection;
  • Advanced cryptographic techniques for intrusion detection;
  • Malware/ransomware identification and prevention.

In this paper, we present PhiShield, which is a spam filter system designed to offer real-time email collection and analysis at the end node. Before our work, most existing spam detection systems focused more on detection accuracy rather than usability and privacy. PhiShield is introduced to enhance both of these features by precisely choosing the deployment location where it achieves personalization and proactive defense. The PhiShield system is designed to allow enhanced compatibility and proactive phishing prevention for users. Phishield is implemented as a browser extension and is compatible with third-party email services such as Gmail. As it is implemented as a browser extension, it assesses emails before a user clicks on them. It offers proactive prevention for users by showing a personalized report, not the content of the phishing email, when a phishing email is detected. Therefore, it provides users with transparency surrounding phishing mechanisms and helps them mitigate phishing risks in practice. We test various locally trained Artificial Intelligence (AI)-based detection models and show that a Long Short-Term Memory (LSTM) model is suitable for practical phishing email detection (>98% accuracy rate) with a reasonable training cost. This means that an organization or user can develop their own private detection rules and supplementarily use the private rules in addition to the third-party email service. In this paper, we implement PhiShield to show the scalability and practicality of our solution and provide a performance evaluation of approximately 300,000 emails from various sources. Full article
