Linux fights off hackers
Linux systems are getting tougher for hackers to crack, security experts have reported today.
A study by not-for-profit IT security testing organisation Honeynet Project has shown that, on average, Linux systems today take three months to fall prey to hackers, up from 72 hours in equivalent tests conducted between 2001 and 2002.
The 2004 results came after a team of researchers set up 19 Linux and four Solaris 'honeypots' in eight countries including the UK. Honeypots are unpatched internet-connected computers designed to be targets for hackers.
"Default installations of Linux distributions are getting harder to compromise," said the report.
"New versions are more secure by default, with fewer services automatically enabled, privileged separation in services such as OpenSSH, host-based firewalls filtering inbound connections, stack protection for common threats and other security mechanisms."
