The threat of running unnecessary services on a system bloated with extra software is a less commonly discussed security concern. Yet enabled and listening services weaken the server’s defences by creating potential entry points for the attacker, as well as by providing resources for the attacker to use against other machines. The server hardening maxim we’re interested in today goes as follows: “Install only necessary software; delete or disable everything else.” With this topic in mind, our task is to examine how this technique applies to a Xen Project hypervisor DomU virtual machine running a paravirtualized Debian 9 operating system.
The purpose of this tutorial is to describe how to install and configure a Xen Project hypervisor with control and guest domains using Debian as the base operating system. Note that this tutorial uses Xen version 4.8.5-pre as included in the current stable release of Debian 9.5 (stretch).

Low interest rates, low unemployment, increased trade, population growth, and stagnated innovation in transportation technology are some of […]
The Bank of Canada‘s January 2018 Monetary Policy Report and November 2017 Financial System Review both highlight the impact of recent government interventions on the country’s hottest housing markets – those of greater Vancouver and Toronto. In many respects, announced interventions have effectively signalled the government’s need to address the risks of inflated residential real […]
The January 2018 Bank of Canada (“BOC”) Monetary Policy Report announced strong growth in the Canadian economy during 2017, including near-capacity levels of economic activity. By their estimates, GDP growth came in at around 3% for 2017 with approximately 70% of that growth derived from domestic consumption – a historically normal level of household consumption […]
Just like the measured weight of an object differs in water versus on land, asset valuations, or measurements, are too affected by their own environmental variables. For example, it’s a reasonable assumption that an asset valued in a booming market is going to generate a different result than if valued during a downturn. For that […]
