The recent outbreak of the Flashback trojan on Mac computers is a case study in how unprepared security professionals are for dealing with malware that's not specific to Windows.

Using the analogy of workers inspecting marbles of varying colors, the author explains how organizations can apply clustering to defend against evolving threats.

A researcher describes a method known as clustering, which can be used to analyze malware patterns and help defend networks from harm.

A noted security researcher explains how sophisticated malware is created to elevate privileges on behalf of an attacker so security controls, such as anti-virus, can be disabled.

As older generations of non-networked health care machines get replaced with 'smarter' network-integrated versions, the proliferation of embedded operating systems will grow.

The concept of malware morphing is not new. For years, malware authors and anti-virus researchers have documented and classified the methods used to obfuscate and hide malware code with each infection.

More access to code means people are bound to be finding more flaws, says Gunter Ollmann

It’s all too easy to let minor security problems get sidelined, warns Gunter Ollmann, but they need attention

Online authentication security is vital, but much of it can be carried out in a paper review, says Gunter Ollmann

We hear a lot about new vulnerabilities, but as Gunter Ollmann explains, there are still plenty waiting for a patch
