Abstract

Malware attacks on the Internet have increasedsubstantially in recent years for which botnets are a root cause. A "botnet" is a network of compromised computers controlled by an attacker known as the "botmaster". To be able to effectively detect and defend against botnets, it is very important to have a good understanding of their construction procedure and propagation methodology. In this work, we study the construction of an unstructured peer-to-peer botnet, its propagation methodology, diurnal properties and robustness. This simulation shows that the more frequently a node updates its buddy list, the lesser is the process overhead involved.

Abstract

Many applications are developed and deployed in Syiah Kuala University main server. These applications and information system are built as tools to help the University’ daily activities. Most of these applications have its own database. As a result, data is inconsistent, and the worst is redundant data cannot be avoided. The idea behind of this research is to build one centralized data that can be used as baseline to other applications. Since the main data of Syiah Kuala University are located behind the proxy which is no internet direct access allowed to the data. The proposed method to answer this problem is touse web service as a gateway for data transfer. This technique keeps the database from direct external access but the data itself can be seen without knowing where the real data is. This method has been used for Online Exit-Survey to proof that the system can verify the students’ data. Some student cannot be identified because their data were empty, the other because the data in centralized database server were only prepared for undergraduate students, so that the post graduate and professional students cannot be verified. For undergraduate students this online exit-survey works fine without error on verification phase

Abstract

Raspberry Pi is a small-sized computer, but it can function like an ordinary computer. Because it can function like a regular PC then it is also possible to run a web server application on the Raspberry Pi. This paper will report results from testing the feasibility and performance of running a web server on the Raspberry Pi. The test was conducted on the current top three most popular web servers, which are: Apache, Nginx, and Lighttpd. The parameters used to evaluate the feasibility and performance of these web servers were: maximum request and reply time. The results from the test showed that it is feasible to run all three web servers on the Raspberry Pi but Nginx gave the best performance followed by Lighttpd and Apache.Keywords: Raspberry Pi, web server, Apache, Lighttpd, Nginx, web server performance
