Experts at Sophos have advised businesses to take action to defend their Windows computers after Microsoft issued a warning of critical security flaws in its software.

As part of its monthly "Patch Tuesday" schedule Microsoft has issued a number of bulletins about security vulnerabilities in its software. The list of affected software includes versions of the Windows operating system, Microsoft Office and Internet Explorer.

"Everyone responsible for the security of data on Windows computers needs to sit up and listen when Microsoft issues a security warning about its software," said Graham Cluley, senior technology consultant at Sophos. "The rise in financially-motivated hacking has made it more important than ever to ensure that your business is properly defended with the latest patches."

Home users of Microsoft Windows can visit to have their systems scanned for Microsoft security vulnerabilities.

Sophos suggests that every IT manager responsible for security should consider subscribing to vulnerability mailing lists such as that operated by Microsoft at

How can Network Access Control help your business?

Network Access Control enables companies to control who and what is allowed onto their network; blocking unauthorized users, controlling guest access, and ensuring compliance with a business's security policy. By implementing NAC firms reduce the risk of unauthorized, guest, non-compliant, or infected systems compromising the network, ensuring that only correctly secured computers gain network access.

Sophos continues to recommend companies protect their desktops and servers with automatically updated protection against viruses, spyware, hackers, and spam.
