The Systems Administration and Network Security (SANS) Institute (www.sans.org) is probably one of the best-known purveyors of what by all accounts is truly outstanding security training, including their general (GSEC) security class and their intruder detection class. Both of these offerings are available in the classroom at SANS conferences, which will be in London from Aug. 5-10 (rather short notice, I know) but also in Spain (Nov. 11-16) and Amsterdam (Nov. 20-25) later this year. They also offer excellent online courses for both GSEC and intusion detection topics.
Other potential sources of such training would include the many excellent colleges and universities in your country, some of which are world leaders in IT security. Here again, I'd urge you to use your local search engines to help you identify and select such offerings.
Good luck in your search for just the right courses, online or in the classroom.
