Basic vulnerabilities statistics

A distributed network of ‘honeypots’, computers running special network traffic capture software, can be used to easily track the distribution of the most popular exploits and commonly exploited vulnerabilities. Collecting data from a reasonably large number of systems,and sorting it by type, source and destination provides statistics on the most common attacks, the most secure (or insecure) geographical areas and how the preferences for one set of exploits or another changes over time.

For instance, here’s the list of the most exploited vulnerabilities collected by the Smallpot project for September 2004:

The SANS (SysAdmin, Audit, Network, Security) Institute and the National Infrastructure Protection Center (NIPC) at the FBI also releases a document listing the most critical Internet security vulnerabilities every year.

This is SANS Top 20 vulnerabilities for 2004:

If you want to make the world safer, start with the smart things in your home. Or, to be more specific, start with your router – the core of any home network as well as an interesting research object. And that router you got from your ISP as part of your internet contract is even more interesting when it comes to research. Read Full Article
