If you use Google's Enterprise search technologies to power your company's internal document search, a post about document-level security at the Google Enterprise Blog might be worth a read.  Nitin Mangtani, product manager for the Google Search Appliance, responds to an article published in New Idea Engineering about ways to implement document-level security and explains the reasoning Google uses to select the type of security their search products implement.

Security has been a hot topic for years, spurred in no small part by the rising use of the internet as a launching ground for digital attacks on corporations and individuals.  Corporate websites and intranets should have security policies in place to prevent breaches of data from both the outside and the inside.

Keep this in mind when rolling out website and intra-company search services.
