The rise of non-Windows operating systems in the enterprise and the easy availability of powerful hardware is killing the "one OS for one box" model. This is a good thing because it allows users to easily work with, test on, and develop for multiple operating systems. And the best way to accomplish this is with virtualization.

A very well integrated solution to monitor your network, applications and servers is the combination of Jalasoft Xian Network Manager Io with Microsoft System Center Operations Manager 2007. In a very user friendly and single console environment, you are able to monitor your windows servers, Linux servers, virtual servers, switches, routers and many other network devices. On the Xian Io side you can easily add network devices and set up rules. All without any complicated scripting, just a matter of drag and drop the rules. Xian Io comes with about 100 build in rules per device type!

This paper discusses the advantages of using BalaBit Shell Control Box (SCB) to control remote access to your UNIX/Linux servers and Windows Terminal Services. SCB can transparently control, audit and replay the Secure Shell (SSH) and Remote Desktop (RDP) protocols commonly used to remotely access and manage servers. The document is recommended for technical experts and decision-makers working on auditing server-administration processes for policy compliance (e.g., PCI-DSS), or for forensics situations in case of security incidents.

The introduction of Linux brought the promise of a new level of cost-efficiency and flexibility in enterprise IT
environments. But as Linux systems scale, management typically becomes unwieldy. The prohibitive cost of managing large installations over time, making sure every single server is running right, rolling out updates and security patches, even up to thousands of servers, has gotten in the way of achieving Linux’s full potential.
The core challenges include massive heterogeneity, sheer volume of equipment and data, and lack of nimble
management tools.
Levanta has created a new administration model with innovative technology that breaks down the barriers to
making the most of Linux systems. This paper will provide an in-depth look at the workings of Levanta’s product,
the first Linux appliance of its kind.
