How secure is secure?

Recently, LinkedIn has leaked 6.5 million account passwords. A few months ago, a Chinese IT website CSDN leaked over 6 million user accounts. Worse for CSDN is that they stored the passwords as plain text format which can be easily cracked by hackers. Actually, many information leak accidents happened in the past. Information security is always a big concern for all of us. Do you have any idea on how we should keep our information secure? Do you think how secure is secure?
