Three leading suppliers of Linux systems have said they will use Tripwire's intrusion detection and prevention software to make Linux more secure for e-business.
Tripwire also plans to release an open source version of the software during the third quarter.
The move by Caldera, Red Hat, and SGI should help convince IT managers that Linux is a secure operating system for vital business applications, said Aberdeen Group analyst Eric Hemmendinger.
" With the increased dependence on Linux, decision-makers need security tools that are transferable to Linux environments — including integrity assessment tools. Tripwire's expansion into the Linux and open source communities offers market-leading solutions on platforms that are being rapidly adopted by enterprises."
Tripwire detects intruders or unauthorised changes made to a system's key files and directories. It then notifies users when intrusions occur on important systems.
