Identifying and fixing security vulnerabilities before an attacker exploits them is one of the most difficult tasks an administrator faces. Virtually any infrastructure component can become a target for crooks. Web applications, with their cornucopia of cross-site scripting (XSS) and other injection attacks, are a problem, as are systems with unpatched software, insecure user accounts, misconfigured firewalls, poorly protected network devices, and so on. At the same time, IT setups are becoming increasingly complex, comprising increasing numbers of components. What’s more, sometimes you do not know exactly what components you are dealing with locally. The best way to prevent attacks is to identify and eliminate security risks before an attack happens. Of course, you cannot hope to do this manually if you have thousands or more virtual instances running the most diverse software zoo imaginable in your company data center. The only tools that can help you there are those that automatically query entire networks or hosts and search for specific vulnerabilities.
Google comes to the aid with its Tsunami [1] offering. Because it is not an official project, Google does not provide any support. That said, Tsunami is now available under the Apache license on GitHub, and the tool can be used without any further Google involvement.
