Teknologi virtualisasi server merupakan penggunaan bersama satu mesin fisikal oleh beberapa sistem operasi server. Perancangan dan implementasi mail server ini dibangun dengan menggunakan Debian.5 sebagai base operating system server. Perancangan dan implementasi mail server ini dibangun dengan menggunakan dns server, web server dan mail server/squirrelmail, di konfigurasi menggunakan bantuan aplikasi virtualbox sebagai server. DNS (Domain Name System) adalah sebuah sistem yang menyimpan informasi tentang nama host maupun nama domain dalam bentuk basis data tersebar (distributed database) di dalam jaringan komputer, misalkan Internet. Aplikasi yang digunakan untuk menangani penghantaran pesan mail adalah mail server. Mail server ini senantiasa menerima pesan dari e-mail client yang digunakan user, atau mungkin dari server e-mail lainnya. Web mail berfungsi untuk mengirim dan melihat pesan email melalui web browser. Konfigurasi squirrelmail dilakukan dengan menjalankan skrip conf.pl : $/var/www/wemail/config/ conf.pl. Layanan Exchange Server antara lain : Directory Service, Simple Mail Transfer Protocol (SMTP), Post Office Protocol ( POP3 ), IMAP (Internet Message Access Protocol), Complementary Services, System Attendant. Untuk Proses Pengiriman Mail Server dapat dilihat pada nomor 5.2. Kata Kunci: Squirrelmail, Exchange Server, DNS Server, Web Server, Mail Server.

In previous chapters of this book, crypto systems, security mechanisms, and security services have been discussed and reviewed as separate crypto modules. In Chapters 10 to 14, how these crypto modules are used to provide network security will be discussed. Electronic mail enables users to exchange messages using computer communications facilities, but sending an e-mail message is like sending a postcard that anyone can read as it travels from post office to post office. When an e-mail message travels from one e-mail server to another, the e-mail is first stored in an e-mail server before it is sent to the next e-mail server. A way to protect e-mail is by using writer-to-reader security in which the message is encrypted at the sender station and deciphered at the receiver station. There are several ways to make e-mail secure. Pretty Good Privacy (PGP) and Secure MIME (S/MIME) are presented in this chapter.

ABSTRACT   Electronic mail or commonly called e-mail is a mailing service that uses computer network for sending and receiving mail. On the other hand, e-mail mostly used as one of the supporting media for any communication activities. Therefore the purpose of this research is applying auto backup email system on mail server at Unisma Bekasi software laboratory.  Mail server used is Zimbra open source with Ubuntu Linux 14.04 operating system. To support the necessary elements, the bind9 system is used for naming the domain name that provides addressing on the server system. By having cronjob feature on Webmin, it makes a solution automatically command for auto backup which is combined with scrip. User account capacity and mailbox on mail server Zimbra can accommodate bigger mail compared to other servers such as qmail or postfix.     Key words: mail server, open source, zimbra, cron job, auto backup.        ABSTRAK   Surat elektronik atau biasa disebut e-mail adalah suatu layanan surat menyurat yang menggunakan media jaringan komputer dalam mengirim dan menerima surat. Penggunaan e-mail sendiri lebih banyak dipakai sebagai salah satu media pendukung dari setiap kegiatan komunikasi. Tujuan dari penelitian  ini adalah menerapkan sistem auto backup email pada mail server pada laboratorium software Universitas Islam 45. Mail server yang digunakan adalah zimbra open source dengan sistem operasi Linux Ubuntu 14.04. Untuk mendukung unsur-unsur yang diperlukan, penamaan nama domain menggunakan sistem bind9 yang menyediakan pengalamatan pada sistem server. Dengan adanya fitur cron job pada webmin, menjadikan solusi untuk melakukan sebuah perintah otomatis dalam melakukan auto backup yang dikombinasikan dengan script. Kapasitas user account dan mail box pada mail server zimbra dapat menampung lebih banyak dibandingkan mail server lainnya, seperti qmail atau postfix.   Kata kunci: mail server, open source, zimbra, cron job, auto backup.

The VoIP communication system at OMNI Hospital Alam Sutera uses the Elastix 2.5 server with the Centos 5.11 operating system. Elastix 2.5 by the developer has been declared End of Life. The server security system is a serious concern considering that VoIP servers can be accessed from the internet. Iptables and fail2ban applications are applications that are used to limit and counteract those who try to attack the VoIP server. One application that can be used as an open source VoIP server is the Issabel Application version 4.0. The migration process from Elastix 2.5 application to Issabel 4.0 by backing up all configurations in the Elastix 2.5 application through a web browser including the configuration of endpoints, fax, e-mail, asterisk. After the backup file is downloaded then upload the backup file to the Issabel 4.0 application then run the migration process. Adding a backup path as a failover connection is needed because the VoIP communication protocol between the OMNI Hospitals Group still uses one path so that when there is a problem in the connection path, the communication protocol will stop. The tunnel EoIP is a protocol used as a backup path between the OMNI Hospitals Group site.

If we are talking about user behavior analytics, we have to understand what the main source of valuable information is. One of these sources is definitely a web server. There are multiple places where we can extract the necessary data. The most common ways are to search for these data in access log, error log, custom log files of web server, proxy server log file, web browser log, browser cookies etc. A web server log is in its default form known as a Common Log File (W3C, 1995) and keeps information about IP address; date and time of visit; ac-cessed and referenced resource. There are standardized methodologies which contain several steps leading to extract new knowledge from provided data. Usu-ally, the first step is in each one of them to identify users, users’ sessions, page views, and clickstreams. This process is called pre-processing. Main goal of this stage is to receive unprocessed web server log file as input and after processing outputs meaningful representations which can be used in next phase. In this pa-per, we describe in detail user session identification which can be considered as most important part of data pre-processing. Our paper aims to compare the us-er/session identification using the STT with the identification of user/session us-ing cookies. This comparison was performed concerning the quality of the se-quential rules generated, i.e., a comparison was made regarding generation useful, trivial and inexplicable rules.
