Covert channel detection using Information Theory [PDF]
Electronic Proceedings in Theoretical Computer Science, 2010 This paper presents an information theory based detection framework for covert channels. We first show that the usual notion of interference does not characterize the notion of deliberate information flow of covert channels.

Detection of Covert Channels Over ICMP Protocol [PDF]
2017 IEEE/ACS 14th International Conference on Computer Systems and Applications (AICCSA), 2017 With the growing complexity of networks and communications protocols that become increasingly enormous and extensive, we are confronted with the problem of covert channel that affects the confidentiality and integrity of data sent in the network. Covert channels also known as hidden channels can elude basic security systems such as Intrusion Detection ...

Covert Channel Detection: Machine Learning Approaches [PDF]
IEEE Access, 2022 The advanced development of computer networks and communication technologies has made covert communications easier to construct, faster, undetectable and more secure than ever. A covert channel is a path through which secret messages can be leaked by violating a system security policy. The detection of such dangerous, unwatchable, and hidden threats is

Covert Channel Detection Using Machine Learning
2020 28th Signal Processing and Communications Applications Conference (SIU), 2020 A covert channel is a communication method that misuses legitimate resources to bypass intrusion detection systems. They can be used to do illegal work like leaking classified (or sensitive) data or sending commands to malware bots. Network timing channels are a type of these channels that use inter-arrival times between network packets to encode the ...

A framework for network covert channel detection
, 2020 Since the dawn of human communications, there have been people that have wished to correspond secretly with others. Some people have desired the content of their communication to be kept confidential; some wish the very fact that they are communicating to remain unknown.

Detection of DNS based covert channels [PDF]
, 2015 Information theft or data exfiltration, whether personal or corporate, is now a lucrative mainstay of cybercrime activity. Recent security reports have suggested that while information, such as credit card data is still a prime target, other data such as corporate secrets, employee files and intellectual property are increasingly sought after on the ...

Detection of communication over DNSSEC covert channels
, 2016 Unauthorized data removal and modification from information systems represents a major and formidable threat in modern computing. Security researchers are engaged in a constant and escalating battle with the writers of malware and other methods of network intrusion to detect and mitigate this threat.
