A New Architecture for Enhancing the Security of E-Mail System
نویسندگان
چکیده
In this paper, we propose a bridge-type e-mail proxy architecture to release the bottlenecks of the two popular mail security architectures: software mail filter and e-mail gateway. In the proposed architecture, a bridge-type e-mail proxy is located in front of mail server and sniffs all flowing packets on the network. If sniffed packets belong to one of mail protocols, the proposed system filters the packets just as an e-mail proxy system does. But if a sniffed packet does not belong to mail packets, it is forwarded just as a normal network bridge does. The proposed architecture has several merits. Keyword: e-mail, proxy, spam, bridge

A New Hybrid Approach of K-Nearest Neighbors Algorithm with Particle Swarm Optimization for E-Mail Spam Detection
Emails are one of the fastest economic communications. Increasing email users has caused the increase of spam in recent years. As we know, spam not only damages user’s profits, time-consuming and bandwidth, but also has become as a risk to efficiency, reliability, and security of a network. Spam developers are always trying to find ways to escape the existing filters therefore new filters to de...
متن کاملGenetic and Memetic Algorithms for Sequencing a New JIT Mixed-Model Assembly Line
This paper presents a new mathematical programming model for the bi-criteria mixed-model assembly line balancing problem in a just-in-time (JIT) production system. There is a set of criteria to judge sequences of the product mix in terms of the effective utilization of the system. The primary goal of this model is to minimize the setup cost and the stoppage assembly line cost, simultaneously. B...

Composition, change and complexity have attracted ev- eryone’s attention towards Self-Adaptive systems. These systems, inspired by the human body, are capable of adapting to changes in the inner and outer environment. The main objective of this study is to achieve a more con- venient availability for e-banking services in the payment switch, using self-healing systems and focusing on the failur...

متن کاملHigh capacity steganography tool for Arabic text using 'Kashida'
Steganography is the ability to hide secret information in a cover-media such as sound, pictures and text. A new approach is proposed to hide a secret into Arabic text cover media using "Kashida", an Arabic extension character. The proposed approach is an attempt to maximize the use of "Kashida" to hide more information in Arabic text cover-media. To approach this, some algorithms have been des...
