HP has unveiled a series of Linux-based OS offerings, adding proprietary layers to the open source operating system. The company has released a security-enhanced version and a scaled-down system for devices using an embedded OS.

HP is not the first company to offer hardened versions of Linux - many independent integrators do similar work, and the US intelligence agency NSA offers a freely downloadable configuration. In most cases, the solution is just that - configuration specifically designed to stave off attacks. In HP's case, the company has bundled additional security software onto the system.

HP Secure OS Software comprises multiple layers designed not only to prevent penetration, but also to detect and contain an attack should it succeed at all. Unauthorised connections between processes and potentially dangerous file operations, for example, are tightly controlled.

For intelligent devices, HP has developed Chai-LX, a Linux-based embedded software platform which allows devices to host Java applications and Web services. The platform ties together HP's existing Chai software with a tweaked Linux kernel and a range of Java applicatins.
