Public-private partnership (PPP) describes a government service or private business venture which is funded and operated through a partnership of government and one or more private sector companies.
Here's an example of "public-private partnerships": Recently, six Estonian nationals have been arrested and charged with running a sophisticated Internet fraud ring that infected millions of computers worldwide with a virus and enabled the thieves to manipulate the multi-billion-dollar Internet advertising industry. Users of infected machines were unaware that their computers had been compromised -- or that the malicious software rendered their machines vulnerable to a host of other computer viruses.
Beginning in 2007, the cyber fraud ring used a class of malware called DNSChanger to infect approximately 4 million computers in more than 100 countries. There were about 500,000 infections in the U.S., including computers belonging to individuals, businesses, and government agencies such as NASA.
The FBI further states "A complex international investigation such as Operation Ghost Click could only have been successful through the strong working relationships between law enforcement, private industry, and our international partners."
The private partnerships refer to corporations just like yours who may have been affected by a virus or play a role in information security that help track down the bad guys. "PPP involves a contract between a public sector authority and a private party, in which the private party provides a public service or project and assumes substantial financial, technical and operational risk in the project."
As President John F Kennedy once said "Ask not what your country can do for you -- ask what you can do for your country". Today that may mean taking down international cyber criminals.
