Zero-day attack is a critical network attack. The zero-day attack period (ZDAP) is the period from the release of malware/exploit until a patch becomes available. IDS/IPS cannot effectively block zero-day attacks because they use pattern-based signatures in general. This paper proposes a Prophetic Defender (PD) by which ZDAP can be minimized. Prior to actual attack, hackers scan networks to identify...
HTTP is the main protocol of the Internet and many network applications rely on it. Malware also utilizes it as a covert channel through which to evade the firewall (FW) or network intrusion detection system (NIDS). We recognize a malware, which employs HTTP to communicate as the HTTP-like Botnet. Some parts of the network traffic of an HTTP-like Botnet are different from normal HTTP applications...
Network anti-virus (AV) solutions are the first line of defense against malicious software. Traditional proxy-based network anti-virus solutions with store-scan-forward techniques decrease network performance and consume massive amounts of memory. Therefore, traditional solutions are not easily adaptable for Network Function Virtualization (NFV). This paper details the work on a novel virus scanning...
