Ten Immutable Laws of Security
Law #1: If a bad guy can persuade you to run his program on your computer, it's not your computer anymore
Law #2: If a bad guy can alter the operating system on your computer, it's not your computer anymore
Law #3: If a bad guy has unrestricted physical access to your computer, it's not your computer anymore
Law #4: If you allow a bad guy to upload programs to your website, it's not your website any more
Law #5: Weak passwords trump strong security
Law #6: A computer is only as secure as the administrator is trustworthy
Law #7: Encrypted data is only as secure as the decryption key
Law #8: An out of date virus scanner is only marginally better than no virus scanner at all
Law #9: Absolute anonymity isn't practical, in real life or on the Web
Law #10: Technology is not a panacea

HK police information leakage

Look like most Government don't handle data security well. Recently HK police information leakage case is one of great example:

http://www.thestandard.com.hk[..]35&sid=7287851&con_type=1&d_str=20060330
http://www.google.com[..]ge+case&sourceid=opera&ie=utf-8&oe=utf-8

However, this is not only HK problem some other countries facing similar problem also: http://thedailywtf.com/forums/65974/ShowPost.aspx http://thedailywtf.com/forums/71199/ShowPost.aspx

For HK case, look like it just some idiots in Government given out real data for testing, of course the IT service provider should also check the data and keep the data secure even for test data.

But for later case, it is more trick, it turn out Googlebot is too clear to bypass the security trick which call GET HTTP command to delete link everyday. Remember, all client side security is not safe.
