An article written a year ago at IT World titled 'Four Telecommuting Security Mistakes' received a response at a blog I subscribe to yesterday and both proved to be interesting reads. Although the articles are discussing telecommuting, it really seems to apply to any of the library-issued devices including our loaner laptops, projectors, and Blackberries.
IT World Article: Four Telecommuting Security Mistakes
Roger's Information Security Blog: Telecommuting Security
At first read, there seems to be a discrepancy between what the article describes and the practices we have in place (or at least what we see as a result). Some of that might be attributed to differences between private industry and academic, but I don't think computer security should see any difference.
