Understanding and Detecting Majority Attacks
2020 IEEE International Conference on Decentralized Applications and Infrastructures (DAPPS), 2020Blockchain technologies are becoming increasingly popular for financial and business solutions thanks to their many features and adaptability. However, their security is not assured. Of particular concern are majority attacks, which exploit the consensus algorithm used to resolve competing chains to modify past and present transactions on the ...

On the detection of pod slurping attacks
Computers & Security, 2010Time is recognised to be a dimension of paramount importance in computer forensics. In this paper, we report on the potential of identifying past pod slurping type of attacks by constructing a synthetic metric based on information contained in filesystem timestamps. More specifically, by inferring the transfer rate of a file from last access timestamps

DDoS Attacks Detection with AutoEncoder
NOMS 2020 - 2020 IEEE/IFIP Network Operations and Management Symposium, 2020Although many distributed denial of service (DDoS) attacks detection algorithms have been proposed and even some of them have claimed high detection accuracy, DDoS attacks are still a major problem for network security. The latent and inherent problems of these detection algorithms are 1) Requirement of both normal and attack data for building ...

A Calculus to Detect Guessing Attacks
2009We present a calculus for detecting guessing attacks, based on oracles that instantiate cryptographic functions. Adversaries can observe oracles, or control them either on-line or off-line. These relations can be established by protocol analysis in the presence of a Dolev-Yao intruder, and the derived guessing rules can be used together with standard ...

Scalable Detection of Cyber Attacks
2011Attackers can exploit vulnerabilities to incrementally penetrate a network and compromise critical systems. The enormous amount of raw security data available to analysts and the complex interdependencies among vulnerabilities make manual analysis extremely labor-intensive and error-prone. To address this important problem, we build on previous work on

On the Sybil attack detection in VANET
2007 IEEE Internatonal Conference on Mobile Adhoc and Sensor Systems, 2007Since few years, Vehicular Ad hoc Networks deserve much attention. The development of wireless communication in VANET implies to take into account the need of security. In VANET, many attacks rely on having the attacker generate multiple identities to simulate multiple nodes: this is called the Sybil attack.

Network Attack Detection and Mitigation
2015 IEEE International Conference on Self-Adaptive and Self-Organizing Systems Workshops, 2015Resource exhaustion attacks or denial of service attacks (DoS) have emerged as a major way to compromise the availability of servers and interrupt legitimate online services. IP trace back refers to the problem of identifying the source of such attacks. Packet marking is a general technique to trace back attackers. The main idea in packet marking is to

Targeted attacks detection with SPuNge
2013 Eleventh Annual Conference on Privacy, Security and Trust, 2013Over the past several years there has been a noticeable rise in the number of reported targeted attacks, which are also commonly referred to as advanced persistent threats (APTs). This is seen by security experts as a landscape shift from a world dominated by widespread malware that infect indiscriminately, to a more selectively targeted approach with ...

On Detecting Code Reuse Attacks
Automatic Control and Computer Sciences, 2020Today, a code reuse technique is often used when exploiting software vulnerabilities, such as a buffer overflow. These attacks bypass the protection against execution of code in the stack, which is implemented on the hardware and software levels in modern information systems. The attacks are based on finding suitable sections of executable code–gadgets–

Detecting SYN flooding attacks
Proceedings.Twenty-First Annual Joint Conference of the IEEE Computer and Communications Societies, 2003We propose a simple and robust mechanism for detecting SYN flooding attacks. Instead of monitoring the ongoing traffic at the front end (like firewall or proxy) or a victim server itself, we detect the SYN flooding attacks at leaf routers that connect end hosts to the Internet. The simplicity of our detection mechanism lies in its statelessness and low
