The botnet is considered as a critical issue of the Internet due to its fast growing mechanism and affect. Recently, Botnets have utilized the DNS and query DNS server just like any legitimate hosts. In this case, it is difficult to distinguish between the legitimate DNS traffic and illegitimate DNS traffic. It is important to build a suitable solution for botnet detection in the DNS traffic an...

P2P botnet is one of the most critical threats to the current Internet security. In this paper, we propose a session-based analysis and minimum vertex cover mining detecting model for core nodes of P2P botnets. This model is focused on solving the core nodes of botnet and has a good performance when the characteristics of botnet are changed to avoid detecting. The simulation experiments reveal ...

Botnets are prevailing mechanisms for the facilitation of the distributed denial of service (DDoS) attacks on computer networks or applications. Currently, Botnet-based DDoS attacks on the application layer are latest and most problematic trends in network security threats. Botnet-based DDoS attacks on the application layer limits resources, curtails revenue, and yields customer dissatisfaction...

life cycle assessment (lca) is one of the decision support systems which can be considered for assessing the different approaches of waste management. however, it only considers environmental effects and ignores other decision making options such as economic and social effects of solid waste management. in this research, we consider a combination of three decision making options including en...

effect of five soybean varieties (sahar, jk, bp, williams and l17) on life cycle and fecundity of the beet armyworm, spodoptera exigua (hã¼bner) was evaluated at temperature of 25 â± 1â°c, 60 â± 5% r.h. and a photoperiod of 16: 8 (l: d) h. the preimaginal development period of males and females was longest on l17 (30.17 â± 0.28 and 29.63 â± 0.23 days) and shortest on bp and sahar. the adult lon...

Botnets are recognized as one of the most dangerous threats to the Internet infrastructure. They are used for malicious activities such as launching distributed denial of service attacks, sending spam, and leaking personal information. Existing botnet detection methods produce a number of good ideas, but they are far from complete yet, since most of them cannot detect botnets in an early stage ...

Malicious software infects large numbers of computers around the world. Once compromised, the computers become part of a botnet and take part in many forms of criminal activity, including the sending of unsolicited commercial email or spam. As mobile devices become tightly integrated with the Internet, associated threats such as botnets have begun to migrate onto the devices. This paper describ...

Botnets pose a severe threat to the security of Internet-connected hosts and the availability of the Internet's infrastructure. In recent years, botnets have attracted many researchers. As a result, many achievements in studying different botnets' anatomies have been made and approaches to botnet detection have been developed. However, most of these approaches target at botnet detection using r...
