    • Deploy a Full-featured Mail Server on OpenBSD 5.1 with iRedMail

      iRedMail installs and configures mail server binary packages automatically from the official software repositories provided by Linux/BSD distribution venders. These packages include: Postfix, Dovecot, Apache, OpenLDAP, MySQL or PostgreSQL, Amavisd and Roundcube. The article is dedicated to Open Source edition of the program.


    • freebsd-update as Intrusion Detection System

      One of the most annoying things a sysadmin can endure is a system intrusion. A script kiddie might only install an IRC bot, but a skilled intruder can carefully replace core system binaries so as to exploit more systems or extract more data. An Advanced Persistent Threat (APT) intruder might even patch and secure a penetrated system, so as to delay detection…


    • Taming the Blowfish with a Dog

      This article is meant to be a quick, yet comprehensive overview of using Kerberos to manage user passwords and single-sign-on on OpenBSD. It is by no way an exhaustive documentation about Kerberos – entire books have been written about it!


    • Upgrading Ports Using Portmaster

      On a FreeBSD server, the system administrator has the choice of using either packages (binary) or the ports system (source). Packages are precompiled binaries from the source in the ports system. These packages come with some sane default options. It is sufficient for a server with minimum customization.


    • Hardening FreeBSD with TrustedBSD and Mandatory Access Controls (MAC) Part 2

      Most system administrators understand the need to lock down permissions for files and applications. In addition to these configuration options on FreeBSD, there are features provided by TrustedBSD that add additional layers of specific security controls to fine tune the operating system for multilevel securit.y From this article you will learn the configuration of the Mandatory Access Controls provided by FreeBSD and how to apply the concepts of the Biba model to FreeBSD.


    • DNSSEC Part 3: Securing the DNS Hosting Environment

      DNS security can be distilled into two maxims: always run the latest version of your chosen DNS software package, and never provide unnecessary information or services to strangers. Put another way, keep current and be stingy! The truth is: DNS servers are susceptible to the same types of vulnerabilities (platform, software, and network-level) as any other host on the Internet. This article will provide guidelines for secure configuration of the DNS hosting environment. The author focuses on three areas: content control of the zone file, securing the DNS host platform and software.
