Currently, the primary concerns on Internet are security and privacy, particularly in encrypted communications to prevent snooping modification of Domain Name System (DNS) data by hackers who may attack using HTTP protocol gain illegal access information. DNS over HTTPS (DoH) is new that has made remarkable progress encrypting traffic modifying spying. To alleviate these challenges, this study ...

Dynamic engineering of application-specific network traffic is becoming more important for applications that consume large amounts of network resources, in particular, bandwidth. Since traditional traffic engineering approaches are static they cannot address this trend; hence there is a need for real-time traffic classification to enable dynamic traffic engineering. A packet flow monitor has be...

The popularity of encrypted communication has grown due to increased security awareness and rapid internet development. End-to-end encryption can prevent data attacks but also poses new cybersecurity threats. Thus, identifying malicious traffic is a focus research in network behavior analysis anomaly detection. Recently, deep learning brought directions for the development classification Based ...

An increasing amount of Internet traffic has its content encrypted. We address the question whether it is possible to predict activities taking place over an encrypted channel, in particular Microsoft’s Remote Desktop Protocol. show that presence five typical can be detected with precision greater than 97% and recall 94% 30-s traces. also design protocol exposes fine-grained actions such as key...

Although the widely-used Transport Layer Security (TLS) protocol hides application data, an unencrypted part of TLS handshake, specifically server name indication (SNI), is a backdoor for encrypted traffic classification frameworks. The recently developed Encrypted ClientHello (ECH) amendment to aims protect privacy-sensitive content message, including SNI. Conversely, ECH can be game-changer i...

As more sensitive information is transmitted over computer networks, there has been a steady increase in the deployment of encryption to protect data in-flight. Myriad encrypted network protocols have emerged [8, 2, 1] that enable various applications like encrypted browsing, VPNs, secure shells, and VoIP. Since the data payload of an encrypted protocol is protected by strong encryption, attack...
