“Easy to learn, Easy to work and Easy to play”, thus goes the advertising slogan of the ASUS Eee PC which is a subnotebook computer designed by Asus and Intel. Its combination of light weight, Linux-based operation system, solid-state drive and relatively low cost make it a very notable device at the time of its introduction.
The Eee PC runs a customtab-based interface and uses IceWM as the default manager on top of its base Linux system which boots in 20 – 22 seconds. Its quick start time is comparable to that of small electronic devices such as mobile phones and PDAs. Intel describes the Eee PC as part of its “World Ahead” marketing drive that aims to provide anyone around the world a chance to own a PC.

Linux and open source are typically the suitable choices for embedded development although they are not magic workers. Tools are considered truly valuable when they are able to assist developers to enable the right features during a product’s short life cycle. In effect, tools selection can either assist or block a developer’s effort to gain control of the project.
With the many aspects of embedded Linux development, the process of building the complex file system it depends on is the one most subject to possible loss of control. This is especially so because platform developers need to integrate and install dozens to hundreds of separate software components that creating a target file system by hand may be time consuming and difficult.

The Mikrotik RouterOS is a Linux-based operating system that lets users turn selected PC, MIPS or Power PC based machines into a full-featured router. This allows features such as firewall rules, VPN server and client, bandwidth shaper, wireless access point and other commonly used features for routing and connecting networks together. MikroTikis, the company, provides wireless ISP systems for Internet connectivity in many countries around the world.
Licensed in escalating levels, more of the available RouterOS is released as the level number rises. The RouterOS is combined with the RouterBOARD and marketed at small to medium sized wireless Internet service providers to provide broadband wireless access in remote areas.
Security Breaches in Authorized Access
April 15, 2011
Security breaches continually occur in spite of the heavy fortification of enterprise perimeters and tight control in user access. Findings would show that majority of documented breaches are committed by internal and external users having authorized access to the system. These users were able to circumvent internal security measures to leapfrog to unauthorized areas when they were only allowed to access a specific area of the network. Controls for privileged users have been dispersed and inadequate.
Xceedium is a network appliance that provides an easy way for companies to create and enforce a granular access policy for highly skilled privileged users. Since all privileged user activities and events are tracked effectively, they cannot easily exploit known holes in Linux and other applications.
