Linux Network Security Higher than Other Platforms

Recent study reveals that Red Hat Enterprise Linux Subscribers were less susceptible to critical Internet security holes.

RALEIGH, N.C.

Red Hat, Inc. (NASDAQ:RHAT), the world's leading provider of open source solutions to the enterprise, today announced that Red Hat Enterprise Linux subscribers were less susceptible to network security holes than users of other platforms according to a recently published report by the SANS Institute. The report identified the top twenty Internet security vulnerabilities. Of the twenty, only two affected Red Hat Enterprise Linux subscribers, for which Red Hat has already issued patches via Red Hat Network.

"There are many research reports that try to compare the number of vulnerabilities between Linux and other operating systems but none take into account the severity of the issues." said Mark Cox head of the Red Hat security response team, "This report shows there are relatively few critical issues affecting users of Linux based operating systems. However, we believe even one is unsatisfactory, and our strategy is to rapidly respond to fix these issues whilst innovating new technology to reduce the risk of future issues."

Established in 1989, SANS (SysAdmin, Audit, Network, Security) is a leading source for information security training and certification. SANS also develops, maintains, and makes available at no cost, the largest collection of research documents about various aspects of information security, and operates the Internet's early warning system - Internet Storm Center. Its programs now reach more than 165,000 security professionals, auditors, system administrators, network administrators, chief information security officers, and CIOs who share the lessons they are learning and jointly find solutions to the challenges they face.
