Permissions : While installing a wordpress plugin or wordpress theme you may change the permission of the files and some plugins like the wordpress anti-spam plugins need you to change permissions so the cron jobs are created and the files are executed automatically but give permissions very carefully and dont do a quick job by giving wrong permissions to important files.
Software Version : Even though there were many problems in the recent wordpress 2.3 upgradation you still need to keep your blogs updated to the latest versions so your blog is safe from the hackers and you dont get into sudden troubles. Just make sure you take a backup of your blog before making the upgrade because it helps in case your blog has some problem with the already installed plugins and themes.

Try to set up passwords which has some local words with some numerical combinations. A Strong password is always important because the most strength you have in your password the more secure you are.
